Opis:

According to the amendment to the Act on maintaining cleanliness and order in communes, a stationary a municipal solid waste collection point (MSWCP) must be established in each Polish commune or commune union and situated close to the commune center. This point (MSWCP) should exist in the commune (or commune union), which are covered in 100% by protected zone. These objects are a new element in managing of the stream of municipal solid waste in Poland, known in the European countries as “household waste recycling centers” (HWRC). The aim of the work was developing the procedure with the use of tools enabling setting potential locations for MSWCPs in protected areas. The developed method was applied (for verification of the assumptions) in the process of seeking optimal locations for MSWCPs in the communes located in the Świętokrzyski National Park (ŚNP) protection zone. The paper presents the methodology for setting locations for municipal solid waste collection points. A method was developed using the Analytic Hierarchy Process (AHP) and Geographical Information System (GIS). It was possible to designate between 98 and 191 potential locations of MSWCPs in the communes situated in the ŚNP protection zone. The assumed criterion of maximum distance from the commune center eliminated 85% of locations. Optimal locations for MSWCPs in each commune were determined using AHP method. The main results of this research was to establish of MSWCP location for every commune in analyzed protected zone, based on the proposed methodology. The method presented in the paper may be a tool for the environment impact assessment of these investments.

Opis:

Generated wastes require space and financial outlays on their proper storage and processing, whereas the lack of means usually leads to depositing wastes in places not meant for this purpose. Illegal dumping sites still emerge, despite introducing in Poland the obligatory (common) fee for collection and management of wastes and the obligatory establishing the Selective Waste Collection Points in each district. The aim of the work was conducting a detailed inventory of illegal dumping sites in the area of Olsztyn district (situated in the Silesia province, on the Krakow-Częstochowa Upland) and indicting the morphological composition of the wastes deposited in these places. The paper presents a detailed analysis of the morphological composition of illegal landfill sites situated in the analyzed district. The investigations located 28 illegal dumping sites, despite the fact that a Selective Municipal Waste Collection Point operates in the district area. The analysis of location, area, mass and composition of the wastes was conducted for each illegal landfill, according to the methodology developed for this purpose. Over a half of the illegal dumping sites was situated in the forest and on 4 of them the estimated mass of dumped waste exceeded 1Mg. Debris constitutes the highest proportion (21.8%) of the waste morphological composition. Recyclable wastes, i.e. glass, plastics, paper and cardboard, used electronic and electric equipment dominated in the morphological composition of wastes on small landfills, situated close to buildings (less than 250m) and had the smallest area (below 1m2 ). The share of debris and construction wastes was growing with increasing landfill area.

Opis:

Mixed municipal solid waste collected from the area of each Polish district (commune) is transferred to Regional Installations for Municipal Solid Waste Treatment. They comprise one or more of the following facilities: installations for mechanical-biological waste treatment (MBT), installations for thermal treatment of municipal solid waste, green waste composting plants and landfill sites. MBT installations have been currently the dominant technology of mixed municipal solid waste treatment in Poland. In these installations mixed waste is subjected to mechanical processes (including: crushing, separation, screening and classification) resulting in the production of the undersize fraction with usual grain size below 80mm and the oversize fraction with grain size over 80mm. Because of the necessity of stabilization and hygenization of the undersize fraction prior to landfilling, it is subjected to the process of biological treatment, e.g. biostabilization. The main aim of the research was to analyze the temperature changes during the biostabilization of the undersized fraction in thermally insulated BKB100 laboratory bioreactor. The research covered a 14-day period of the intensive phase. The analyses were performed in 6 replications. 40.1±2.2kg of waste with density of 519.2±27.5kgˑm-3 and the biodegradable fraction content of 41.9±1.9% was placed in the reactor. The temperature of waste inside the reactor was measured by 9 Pt 1000 temperature sensors. The air for the process was constantly supplied from the outside of the reactor. Flow of the supplied air with temperature of 18.3±3.1°C was regulated depending on the average indication of all temperature sensors. Results of the temperature measurements were averaged and showed using Golden Software Surfer 7. As a result of the conducted research it was found that changes in the temperature inside the bioreactor occurred uniformly throughout its full volume. The time of reaching the temperature of 45°C (the beginning of thermophilic phase) was 25.6±4.0 hours (21 hours at the earliest). During the first period the temperature in the reactor was increasing most intensively in the lower parts of the layer, in the central part of the layer the temperature reached 45°C after 34 hours at the earliest, whereas on average it took 47.7±9.9 hours. The average maximum process temperature was 64.8±3.5°C.

Opis:

Accumulation of municipal solid waste in residential areas is one of the public health problems in Iraq. In the other hand, accurate and reliable information on solid waste generation rate are very important elements to plan and implement solid waste management system. The volume and surface area required for a landfill to dispose the municipal solid wastes generated in Baghdad city is evaluated in this study. The per capita solid wastes generation rates are measured for a family consists of 10 individuals by using portable balance (Salter, 0 to 130 kg). Probability sampling is used to determine the minimum number of measurements needed to evaluate the mean of per capita solid wastes generation rate with a certain level of precision (a specified error level of 5% is selected corresponds to 95% confidence that the mean value is in accurate estimate of the true value). The results indicate that an area of approximately 1603 m on a side is required for the next 20 years as a sanitary landfill for disposing the municipal solid wastes generated in Baghdad city.

Opis:

Municipal Solid Waste (MSW) is the mixture of many waste types, including organic waste (garden and park waste, food and kitchen waste, paper and cardboard etc.). Such waste creates a living environment for various microorganism species, many of which are known as pathogenic. The presence of microorganisms in favorable conditions (pH, organic matter content, carbon content, moisture, appropriate granulation) leads to decomposing of organic matter, which is accompanied by an increase in temperature. Microorganisms in waste pose a serious risk for staff operating at waste treatment plants. Moreover, heat released by their activity may cause a fire in waste storage facilities. Therefore, it is necessary to search for methods of waste stabilization and hygienization. The most commonly applied technology for waste stabilization is its processing in Mechanical Biological Treatment (MBT) plants. Such treatment is capital – and timeconsuming, however. Waste liming can become an alternative method for stabilization and hygienization of waste. Lime addition is one of the oldest method known by humans for hygienization of certain waste materials, such as animal waste. Currently, liming is applied in sewage sludge treatment as one of the initial operations and is necessary for further sludge management processes. The aim of the research was to valuate temperature changes during mixed MSW hygienization process with CaO addition in the amount of several percent by using a thermographic camera. The reaction of CaO with waste is short and lasts no longer than 20 minutes. The maximal temperatures were reached after 65-124 seconds from the time of CaO addition. The most dynamic increase in temperature were observed up to approx. 120th second of the process, with the rate dependent on the initial moisture of the material. The observed pH values indicate that the maximal dose of CaO additive should not exceed 3%. Such a dose is sufficient for waste to reach pH 12, which, according to literature, guarantees the deactivation of microorganisms.

Municipal solid waste management and its disposal are considered one of the major challenges facing the urban communities around the world. Effective solid waste treatment involves a variety of approaches, treatment technologies and concepts to ensure the protection of public health and the environment. Waste landfill is the method most commonly used worldwide, despite all the significant environmental, health and economic consequences. Thus, alternative methods such as the municipal solid waste pretreatment, fermentation, ethanol fermentation and anaerobic fermentation have been the focus of heightened attention. Using these methods, an alcohol-containing liquid was obtained from 1.5 kg of the organic fraction of municipal solid waste (OFMSW), which had an ethanol percentage of 97.45%. Consequently, if properly managed and used, municipal solid waste can be a viable source of energy rather than a source of pollution.

The introduction highlights the technologies of converting the chemical energy of biomass and municipal waste into various forms of final energy (electricity, heat, cooling, new fuels) as important in the pursuit of a low- -carbon economy, especially for energy and transport sector. The work continues to focus mainly on gasification as a process of energy valorization of the initial form of biomass or waste, which does not imply that other methods of biomass energy use are not considered or used. Furthermore, the article presents a general technological flowchart of gasification with a gas purification process developed by Investeko S.A. in the framework of Lifecogeneration.pl. In addition, selected properties of the municipal waste residual fraction are described, which are of key importance when selecting the technology for its energy recovery. Significant quality parameters were identified, which have a significant impact on the production and quality of syngas, hydrogen production and electricity generation capacity in SOFC cells. On the basis of the research on the waste stream, a preliminary qualitative assessment was made in the context of the possibility of using the waste gasification technology, syngas production with a significant share of hydrogen and in combination with the technology of energy production in oxide-ceramic SOFC cells. The article presents configurations of energy systems with a fuel cell, with particular emphasis on oxide fuel cells and their integration with waste gasification process. An important part of the content of the article is also the environmental protection requirements for the proposed solution.

Opis:

Though Municipal Solid Waste (MSW) is a worldwide problem, the collected wastes are dumped in open dumping at landfilling sites while the uncollected wastes remain strewn on the roadside, many-a-time clogging drainage. Such unsafe and inadequate management of MSW causes spread of bacteria, viruses, particulate matter, dioxins and other harmful pollutants in the surroundings and atmosphere. Hence, due to the repeated exposure of population to these pollutants can lead to serious health problems such as Diarrhea/Dysentery, Acute Respiratory Infection (ARI), and Asthma/Chronic Respiratory Diseases (CRD). Therefore, two-phase study included secondary data on diseases caused due to environmental pollution and primary data on MSW and lack of MSW management from 127 households in urban Patna, India. The random sampling method was used for collection of primary survey data, conducted during 2015–16 in selected areas of Patna. Logistic regression model odds ratios and their 95% confidence intervals were used to show the strength of the associations among segregation of wastes at source, segregation behavior, collection bins in the area, distance of collection bins from a residential area, and transportation of MSW. The ROC is a statistical technique to validate the logistic regression method that predicts the occurrence of an event through the comparison of probability picture of an event occurrence observed by probability and the predicted probability of the same event. The area under the ROC curve is up to 0.889 extent, which reveals that the ‘segregation of waste at source’ has a very strong scope to accomplish sustainable recycling at urban Patna in order to manage waste with the overall accuracy of 92.126%, which proves a better fi t logistic regression model. Hence, this paper concludes that ‘segregation of waste at source’ helps to attain sustainable recycling which would be the most viable approach to manage MSW in Patna and would eventually reduce environmental pollutants for the public health safety.

Indonesian municipal solid waste (MSW) is dominated by biodegradable MSW (organic and paper). Due to the degradation process, the physical and hydraulic characteristics of these components can change. It is important to study the physical and hydraulic characteristics of MSW, because landslides occurred in several landfills in Indonesia after heavy rains. Field observations showed that landslides occur due to reduced paper components in the landfill (due to high recycling activities), and cause high percolation of water into the landfill. In the research, 38 samples consisting of two variants of MSW samples (organic and 80% organic + 20% paper), were prepared under the conditions of optimum moisture content. The organic sample of MSW is leaf, while the paper sample of MSW is newspaper, which were shredded to a diameter of about 1 cm. The tests of moisture content, bulk density (in the mould of permeameter), particle size distribution, and permeability were carried out on both sample variants for 90 days, with a test frequency of once in 5 days. The results showed that there was an increase in the moisture content and density, and a decrease in particle size and permeability in both variants of MSW sample. Organic MSW + paper has lower permeability and higher density than organic MSW. This requires further study, because a high paper recycling ratio can lead to a change in the landfill characteristics.

Opis:

Successive closing down of filled-up large municipal landfill sites or those which no longer fulfil the legal regulations, compel local governments and enterprises dealing with waste disposal, to undertake activities aimed at designing and construction of new waste management plants. One of these is a municipal solid waste sorting plant where the waste stream is divided into sub-screen and screen fraction. The screen fraction after removing ferrous and non-ferrous metals, glass and other impurities and crushing to an appropriate particle size constitutes an alternative fuel. The most frequently alternative fuel is manufactured from selectively collected plastics, rubber, textiles and waste paper. Alternative fuel is also manufactured from municipal solid waste in mechanical waste treatment plants. Municipal solid waste is characterized by a non-uniform morphological composition (depending on many factors), which may result in variable parameters of the manufactured fuel. If the waste fuel manufactured in this way and supplied to cement plants does not reach certain quality standards, its price is low, or the product is not accepted for energy recovery. The work presents results of analyses of selected properties of alternative fuels generated from solid municipal waste stream with regard to the type of communes from which the waste originated (urban commune area or rural communes). Statistical analysis was conducted using Bayesian Networks. As it results from the investigations, alternative fuel manufactured from municipal solid waste is characterized by high values of variation coefficient for such parameters as: ash content, moisture and calorific value. The content of carbon, sulphur and incineration heat revealed low values of variance coefficient. The analyses have demonstrated that technological values of alternative fuel do not depend on the administrative type of the communes where the waste used for their production was collected.

Opis:

The changes in the waste management system that have been introduced in Europe and in the world were aimed at counteracting the emergence of illegal dumping sites and increasing the levels of waste recovery and recycling, so that waste management remains in line with the principles of sustainable development and circular economy. The change introduced in 2013 in the municipal waste management system in Poland concerned the assumption of full responsibility by municipalities for the municipal waste collected from owners of residential properties, as well as the establishment and organization of a charging system for residents for the collection and management of the waste. The purpose of the study was to conduct a comparative analysis of fees paid by residents of 93 selected communes of the Lubelskie Province. The study examined the impact of the amount of fees for the waste collection and management on the share of households declaring selective municipal waste collection, the share of selectively collected waste, and the mass accumulation rate of municipal waste. As a result of the analysis conducted using the data from the years 2013–2016, it was revealed that the amount of fees for the collection and management of waste in households that sorted waste contributed significantly to the increase in the percentage of selectively collected waste. Similarly, the smaller the value of the ratio of rates for sorted and mixed waste, the greater the segregation efficiency. This indicates that in the case of the analyzed region, the lower fee charged for sorting waste was an incentive for residents to sort waste.

Opis:

Mechanical biological treatment of waste is still one of the most popular methods for mixed municipal waste treatment. The result of mechanical processing of waste is sorting out: the undersized fraction from municipal solid waste (UFMSW) with granulation below 80 mm, rich in biodegradable organic waste (mainly including food waste, paper, wood, etc.). UFMSW is treated in biological processes in order to reduce the negative environmental effect of this waste. Unfortunately, the processing is not neutral to the environment. The correct course of the aerobic biostabilization process depends on the activity of microorganisms, the intensity of aeration, and the oxygen content in the processed waste. The aim of this paper was to analyze the effect of air-flow rate and biochar addition on the oxygen concentration in waste and in emitted gases during the intensive phase of UFMSW biostabilization. The study was performed under laboratory conditions. Six different variants of the process (without biochar addition and using 1.5; 3; 5; 10 and 20% of biochar addition) were applied. Subsequent replicates were conducted using an averaged air-flow rate of 0.1, 0.2, and 0.4 m3∙d-1∙kg dm.org-1. As a result of the conducted experiments, it was found that both the air-flow rate and the addition of biochar have a significant effect on the oxygen concentration in the treatment waste, as well as its content in the outlet air. Using the highest air-flow rate resulted in the oxygen content not decreasing below 14%, both in the free spaces between the waste and in the emitted gases, while the addition of biochar significantly reduced the oxygen concentration. In the case of lower air-flow rate values, the oxygen content decreased even below 5%. It was found that a high addition of biochar (10 and 20% by weight) at the lowest air-flow rate resulted in the occurrence of anaerobic zones in waste in the first days of the intensive process (between days 2 and 6 of the process), as well as absence of oxygen in the outlet air (between days 2 and 4 of the process). Despite this, no methane (biogas) emissions were found in any of the conducted experiments.

Using the highest air-flow rate resulted in the oxygen content not decreasing below 14%, both in the free spaces between the waste and in the emitted gases, while the addition of biochar significantly reduced the oxygen concentration. In the case of lower air-flow rate values, the oxygen content decreased even below 5%. It was found that a high addition of biochar (10 and 20% by weight) at the lowest air-flow rate resulted in the occurrence of anaerobic zones in waste in the first days of the intensive process (between days 2 and 6 of the process), as well as absence of oxygen in the outlet air (between days 2 and 4 of the process). Despite this, no methane (biogas) emissions were found in any of the conducted experiments.

This paper deals with the estimation of methane emissions from the Mirash municipal solid waste sanitary landfill. The methane emission was calculated according to two different methodologies, namely, IPCC 2006 and LandGEM. Within the framework of the research, the following parameters were evaluated: the amount of landfilled waste, landfill characteristics, and composition of landfilled waste as well as the climate conditions prevailing in the region. According to the IPCC methodology, the total amount of methane emitted from the Mirash landfill during the period 2006–2017 was 30.57 Giga grams (Gg), while according to the LandGEM methodology, the total amount of methane emitted from the Mirash landfill in the period 2006–2017 was 26.32 Giga grams (Gg). The total mass of CH₄ in the Mirash regional landfill for the years 2018–2025 is projected to be 53.74 Gg according to the IPCC method, while according to LandGEM method, the projection points to 50.74 Gg. This study was carried out for the sanitary landfill for solid waste management in Mirash, Prishtina Region, in the Republic of Kosovo, during the year of 2018.

Opis:

The presence of municipal solid waste landfills is an inevitable spatial phenomenon that expresses the planning properties of the process of land use, economic development and the relationship to the environment. The process of land use is continuous, in which a period of planning, development and management of its operation is followed by a period of decline in the performance of (aging) and the fall of the land. Closing the landfill and reclamation results in the appearance of problem areas, i.e. of degraded areas both on the site and in the area of its influence. The paper presents the concept of development of a closed municipal solid waste landfill in the village Woźbin in the commune Cegłów and adjacent areas. According to the ‘Project of closure and reclamation of municipal solid waste landfill in the village Woźbin, in the commune Cegłów’ after the operation of the landfill as well as the technical and biological reclamation, can be implemented forest restoration direction. The concept of developing the reclaimed municipal landfill and the adjacent land is assumed to introduce the planned forest reclamation and complement the recreational function which will increase the attractiveness of the area and will enable its use in a more economical way aimed at integrating the municipal solid waste site with its surroundings.

Opis:

Hydrothermal carbonization (HTC) is known as a thermochemical converting of wet biomass into a coal-like solid fuel (hydrochar). Hydrochar is easily crumbled. Because of hydrophobic properties, hydrochar is difficult to degrade by microorganisms. It has a calorific value comparable to lignite coal. In this study, hydrochar was made via converting the organic fraction of municipal solid waste through HTC at 190, 210, and 230°C for 30 min with feed to water ratio (FWR) 0.1, 0.2, 0.3. The feedstock processed includes food waste, paper, and wood waste, represented as a pseudo-component of the organic fraction of MSW. The high heating value (HHV), FTIR, as well as proximate and ultimate analyses were applied both to feedstock and hydrochar. The results showed that the energy density of hydrochar was elevated with increasing HTC temperature. The energy densification ratio and heating value increased by approximately 1.0–1.32 and 30%, respectively compared to raw feedstock. The lower yields of hydrochar were obtained at higher temperature. The typical char yields for lignocellulosic material range between 62–63 wt% at 190 °C and reduce to 54–57 wt% at 230 °C. Furthermore, a preliminary study of kinetic model for lignocellulose decomposition was conducted. This model was based on the mass loss rate of the lignocellulose compound in HTC of MSW. Three first-order reactions were given to illustrate the hydrochar yield at of 190, 210, and 230°C. The activation energy of lignocellulose decomposition was 76.26 kJ/mol, 51.86 kJ/mol, 12,23 kJ/mol for lignin, cellulose, and hemicellulose decomposition, respectively.

Opis:

The Kingdom of Saudi Arabia (KSA) generates between 1.4–1.75 kg/person/day of Municipal Solid Waste (MSW) that accounts for over 16 million tons of MSW/year. The solid waste collected from different sources is dumped in landfills, thereby creating environmental concerns. In this paper, the potential of solid waste as an energy source (Waste to Energy (WTE)) for Reverse Osmosis (RO) water purification was evaluated. The KSA is known for its acute fresh water shortages and uses desalination technology in meeting its daily water requirements; a process that is energy intensive. The evaluation of the energy content of MSW shows a potential to produce about 927 MW in 2015, based on a total mass burn, and about 1,692 MW in 2032. The MSW-WTE plants can produce about 1.5% of the targeted 120 GW of energy for 2032. For the R.O system, it will give approximately 16.8% of the daily fresh water needed for total mass burn and 2.4% with the recycling option.

Opis:

Nowadays, selective solid waste management in the European Union belongs to important responsibilities of municipalities. In Solid Waste Management (SWM) the main operational task is to set a schedule for solid waste collection and to find optimal routes for garbage trucks, so that the total costs of the solid waste collection service can be minimized, subject to a series of constraints which not only guarantee the fulfillment of the SWM’s obligations but also ensure the desirable quality level of that service. The optimization in garbage truck routing belongs to so called rich Vehicle Routing Problems as it aims to cover the following constraints: pickup nodes (clients) must be visited during their predefined time windows; the number and capacity of depots and specialized sorting units cannot be exceeded; each garbage truck can be assigned to at most one depot; each route should be dedicated to collecting one type of segregated solid waste, and the route must be served by a garbage truck which can collect that type of solid waste; the availability of garbage trucks and their drivers must be respected; each garbage truck must be drained at a specialized sorting unit before going back to the depot. This paper contributes a newly developed Mixed-Integer Programming (MIP) model for the Municipal Solid Waste Selective Collection Routing Problem (MSWSCRP) with time windows, limited heterogeneous fleet, and different types of segregated solid waste to be collected separately. Results obtained for solving small-sized instance of the MSWSCRP are reported.

Opis:

Among solid wastes one may distinguish mixed wastes, segregated wastes (collected selectively) and biodegradable wastes originating from open-air markets, green areas or cemeteries. Mixed wastes have constituted the largest proportion in the stream of municipal solid waste (MSW), both before and after the changes in waste management system in Poland introduced on 1 July 2013. The other group, regarding the collected wastes volume, is so-called segregation. It has been forecasted that in the nearest future the amount of segregated wastes will be successively growing. The article presents the analysis of selectively collected wastes (paper, plastics, glass and metal) indicators from lower administrative units of Liszki and Mogilany communities. The degree of segregated wastes accumulation efficiency was assessed on the basis of conducted computation. The communities selected for the analysis are suburban municipalities, situated in the area of Krakow agglomeration in the immediate vicinity of the main city of the Malopolskie voivodeship. The main aim of the work was an assessment of selective accumulation of municipal solid wastes in suburban communities. Values of quantitative indices, characterizing mixed and segregated municipal solid waste generated by the inhabitants of individual lower administrative units of the studied communities were subjected to a detailed analysis. The data assumed for the investigations cover the period from July 2012 to June 2013. As results from conducted analyses actual indices of wastes accumulation differ from the indices determined on the basis of statistical data and the data stated in the Waste Management Plans, which may evidence a high ecological awareness of the analysed areas inhabitants. The efficiency of selective waste accumulation in the analysed communities was on a similar level and exceeded 20%, i.e. was twice higher than the average for Poland.

Opis:

This study was undertaken to estimate the energy potential of municipal solid waste via creating a relationship between the high heating value (HHV) and the fractions of physical composition of municipal solid waste MSW (% food, % plastic, % paper, % wood, % textile) into the two scenarios, namely wet MSW (as discarded) and dry (free moisture). The created models were determined based on the results of obtained from the analysis of the components of the Al-Diwaniyah MSW and then from previous studies which involved experimental ultimate analysis (% C, % O, % H, % N, %S) of MSW, supported by the equations and models of previous studies which were used for HHV calculation. SPSS Statistical software was used to prepare the models. For each scenario, the input datasets were 60 cases, taking into account the minimization of the data and the average of HHV that result from equations. Four models were created, two models for each status where R2 was 1.00 and 0.999 for dry and wet situation, respectively. However, the equations of verification process showed that the models which depended on the dry fractions are more accurate. The produced HHV from the dry and wet MSW components in the Al-Diwaniyah City is 8655 KJ/Kg and 6440 KJ/Kg, respectively (as discarded).

Opis:

The article presents the results of a research on the processing of undersize fraction, extracted from a stream of mixed municipal solid waste (MSW), into alternative fuel, in the process of bio-drying. The analysis was conducted with the use of an innovative EWA (Ecological Waste Apparatus) bioreactor adapted to carrying out aerobic treatment of waste in such processes as: composting, aerobic digestion/stabilization and bio-drying of waste. EWA bioreactors have been designed and manufactured by AGRO-EKO spol. s r.o. from the Czech Republic. The subject matter of the analysis was undersize fraction, with particle dimensions ranging from 0 to 50 mm, manufactured in the process of sorting (mechanical processing) of MSW. The main aim of the research was to assess suitability of the use of EWA bioreactor in the process of alternative fuel production from undersize fraction developed from municipal waste (in the process of accelerated bio-drying). Samples were collected between 2011 and 2012. The undersize fraction and the produced alternative fuel were analysed by AGRO-EKO spol. s r.o. and at the University of Agriculture in Krakow, in accordance with the standards for wastes and solid fuels. It has been concluded that undersize fraction produced from mixed municipal waste might be the energy source for cement plants or commercial power plants. As a result of a 66-hour accelerated process of bio-drying of undersize fraction (the standard time being ca. 7 days), the waste-mass has been lowered by reducing water content (moisture) in undersize fraction by ca. 15 % while increasing its calorific value and the C:N ratio. The process resulted in the increase of non-combustible and non-biodegradable elements. The high C:N ratio and the amount of organic substances at the level of 78 % should enable further aerobic and anaerobic stabilization preceded by substance moisturizing.

Opis:

Celem artykułu jest określenie granic pojęcia prawnego „odpady komunalne” w odniesieniu do odpadów powstających na nieruchomościach niezamieszkałych, tj. poza gospodarstwami domowymi. Wyznaczenie tych granic ma istotne znaczenie dla zadań i kompetencji gmin w zakresie gospodarki odpadami. Determinuje m.in. zakres przedmiotowy aktów prawa miejscowego w sprawie odbieraniu odpadów komunalnych od właścicieli nieruchomości, a w konsekwencji także zakres organizowanych w tej sferze przez organy gminy przetargów. Autorzy opowiadają się za szerokim ujęciem analizowanego pojęcia, uzasadnionym zarówno brzmieniem odnośnych przepisów, jak i wymogami efektywnej gospodarki odpadami, za którą odpowiedzialność ponosi gmina. Zagadnienie stanowiące przedmiot artykułu jest analizowane z uwzględnieniem zarówno polskich, jak i unijnych regulacji prawnych oraz orzecznictwa.
The aim of the article is to define the boundaries of the legal notion of ‘municipal solid waste’ with respect to solid waste produced in uninhabited property, i.e. outside households. Setting of those boundaries has a significant meaning for tasks and competences of municipalities in the area of solid waste management. It determines, inter alia, the material scope of local legal acts concerning collection of solid waste from property owners, and in consequence, also the extent of tenders organised in this field by the municipal authorities. The authors advocate a broad understanding of the analysed notion, justified by the wording of the relevant legal provisions and the effectiveness of the solid waste management for which municipalities are responsible. The subjectmatter of the article is analysed in the light of both the Polish and EU legal regulations and jurisprudence.

A sustainable performance evaluation of pilot-scale was carried through horizontal sub-surface Constructed Wetlands system for treating the leachate from constructed Municipal Solid Waste Landfill at Institute of Environmental Engineering and Management, Mehran University of Engineering and Technology Jamshoro. The CWs were planted with Phragmites australis, Typha latifolia and Scirpus validus with sand and gravel. The leachate had been treated with two different cycles, first cycle was performed in the winter season whereas second cycle in summer, to differentiate the performance with seasonal variation. Chemical parameters of leachate pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids TSS, Ammonia-nitrogen (NH3-N), Nitrate-nitrogen (NO3-N), Total Phosphate PO43- (TP) and heavy metals, Lead (Pb) and Copper (Cu) were tested with intervals of certain weeks. The tests result showed that all parameters experienced a considerable reduction in their concentrations. Significant reduction efficiencies were recorded for parameters, BOD with 53–82%, COD with 32–46%, TSS with 59–75%, NH3-N with 90–92%, NO3-N with 85–87%, and TP with 48–64%, and heavy metals Pb and Cu with 28–48% respectively in four weeks of the first cycle by all three plants. Whereas, in the second cycle, the removal efficiencies of BOD 78–93%, COD 63–76%, TSS 52–83%, NH3-N 90–91% and NO3-N 91–92% and heavy metals Pb and Cu with 21–58% respectively in five weeks were observed by all three plants. Along with the experimentation, United Nations Sustainable Development Goals UN SDGs are also highlighted. This study helps achieving tremendous SDGs accompanying treatment of leachate.

Opis:

Due to a very high percentage of organic matter in municipal solid waste (47.36%) and in total percentage of biodegradable matter (62.3%), organic waste disposed is the main source of methane emissions into the air in Albania. Capture, collection and utilization of landfill gas in an energy project leads to economic, health and environmental benefits. Energy recovery potential and methane emissions from Tirana landfill have been studied. This site is scheduled to be closed after 6 or 7 years. The evaluation has been done using LandGEM Colombia Model, version 1.0, as an international LFG Modeling. The model predicted the time of peak production in 2019, one year after assumed site closure. The total annual peak of predicted methane recovery from landfill within the study time frame was estimated to be 2950 m³/h and a maximum of power plant capacity 8.3 MW.

Opis:

The subject of the study is the analysis of the number of microorganisms forming a microbiological aerosol in a municipal solid waste treatment plant in Krakow. The storage time of mixed municipal solid waste in the plant hall is 6–48 hours and the storage time of the produced alternative fuel is within the range of 12–96 hours. 18 employees work in the three shift system in the sorting facility. The air for research was sampled using a MAS-100 impactor (Merck, Switzerland) in three locations within the plant, four times within a year to assess the effect of meteorological conditions (temperature, humidity and dustiness) on the number of selected groups of microorganisms. It was found that the number of microorganisms changes with seasons and depends on the meteorological conditions as well as the air sampling location. Since the border values of bioaerosol concentration were exceeded, further research is required to assess the changes in the number of microorganisms with potential negative impact on human health.
Celem pracy była analiza liczebności drobnoustrojów stanowiących biaerozol mikrobiologiczny na terenie zakładu zajmującego się przetwarzaniem odpadów komunalnych w Krakowie. Czas magazynowania zmieszanych odpadów komunalnych w hali zakładu wynosi 6–48 godzin, natomiast czas magazynowania wytworzonego z nich paliwa alternatywnego zawiera się w przedziale 12–96 godzin. W sortowni pracuje 18 osób na 3 zmianach. Powietrze do badań pobierano z użyciem impaktora MAS-100 (Merck, Szwajcaria) w trzech punktach zlokalizowanych na terenie przedsiębiorstwa, cztery razy w roku, aby ocenić wpływ warunków meteorologicznych, tj. temperatura, wilgotność oraz zapylenie na liczebność wybranych grup drobnoustrojów. Stwierdzono, że liczebność badanych mikroorganizmów podlega zmianom sezonowym i jest uzależniona od warunków meteorologicznych oraz punktu poboru powietrza. Ponieważ wartości graniczne dotyczące stężenia bioaerozolu zostały przekroczone, konieczne jest prowadzenie dalszych badań, których celem będzie ocena zmian liczebności drobnoustrojów mogących negatywnie oddziaływać na zdrowie ludzi.

Opis:

The research on the physical and chemical properties of landfill leachates and migration of its hazardous components into hydrosphere and biosphere is a current problem in the global context. The object of the research is landscape-changing factors of the Lviv municipal landfill (Ukraine). It was defined that the largest part of oil products accumulates in the leachates at the south-western side of the landfill (23.6 mg/dm³) and it is 2.36 times higher than the value of the maximum permissible concentration (MPC) (10 mg/dm³); the most saline leachates with chlorides and sulfites are those accumulating at the foot and at the northwestern side; the phosphate content of the investigated leachate samples was the highest at the foot of the landfill and amounted to 12.8 mg/dm³, which exceeds the MPC (10 mg/dm³) by 1.28 times; high concentration of ammonium nitride was discovered in the leachates at the foot (76.1 mg/dm³) and at the northwestern side (46.3 mg/dm³), which exceeds the MPC (30 mg/dm³) by 2.53 and 1.54 times, respectively; the highest indicators of total iron are typical for basins nearby (at the foot – 68.2 mg/dm³, at the northwestern side – 56.3 mg/dm³) and exceed the MPC norms (2.5 mg/dm³) by 27.28 and 22.52 times, respectively. According to certain indicators, the content of hazardous components in the leachates, which accumulate at the foot and at the northwestern side, exceeds the MPC and is several times higher than in the natural basins at the distance of 800 and 1200 m.

Opis:

Landfills throughout the world are contributing to the global warming problem. This is due to the existence of the most important greenhouse gases in landfill gas; namely, methane and carbon dioxide. Methane has a high potential for energy production and by utilizing the proper technology, large amounts of energy can be extracted from it. This paper deals with the estimation of methane emissions from the controlled municipal solid waste landfill of Mohammedia-Benslimane (MB) in Morocco. Methane emissions were calculated using the LandGEM method. In this research, the following parameters were evaluated: the amount of landfilled waste, the characteristics of the landfill and the composition of the landfilled waste, as well as the climatic conditions prevailing in the region. According to the LandGEM model, the total amount of methane generated from approximately 3.663 E+06 kg of municipal solid waste that will be buried of in the MB controlled landfill over 20 years,2012 to 2032, is 1.76 E+08 m3. For the year 2020, the estimated electrical energy production in the landfill is 1.78 E+07 kWh. Regarding the carbon footprint for this landfill, the landfilling of household solid waste at the MB landfill has resulted in a production of about 499,238,000 kg CO2e in 2020 since its opening in 2012, according to the LandGEM model. These huge amounts of greenhouse gas are related to the fact that the waste buried at this landfill is highly organic. By installing an efficient system to capture and flare the biogas generated in this landfill, the management of this landfill is actively contributing to the protection of the environment by mitigating greenhouse gas emissions, particularly methane.

Opis:

W artykule przedstawiono analizę struktury kosztów transportu odpadów komunalnych gromadzonych selektywnie, odbieranych z terenu miasta Krakowa oraz 13 gmin podmiejskich. Do analiz wybrano 4 pojazdy odbierające tzw. segregację z gospodarstw domowych (gromadzoną w różnokolorowych workach). Pojazdy te posiadają zbliżoną charakterystykę pracy. Wszystkie należą do prywatnego przedsiębiorstwa zajmują- cego się zbieraniem i transportem odpadów komunalnych, budowlanych i opakowaniowych. W wyniku przeprowadzonej analizy stwierdzono, iż w strukturze kosztów transportu odpadów segregowanych dla wszystkich analizowanych pojazdów, dominują koszty zużycia paliwa, koszty wynagrodzenia oraz zakupu worków, stanowiące odpowiednio 29,5%, 26,7% i 18,0%. Pozostałe koszty oraz zysk przedsiębiorstwa stanowią 25,8% całkowitych kosztów zbierania i transportu odpadów segregowanych. Koszt transportu 1 Mg odpadów gromadzonych selektywnie wynosi średnio 243,3 zł. Mg-1. Koszt ten jest wyższy o około 60 zł. Mg-1 w stosunku do kosztów transportu zmieszanych odpadów komunalnych. Średnie zu- życie paliwa (ON) w przeliczeniu na 1 Mg segregowanych odpadów komunalnych wynosi około 13,2 dm3·Mg-1 i jest ono wyższe niż zużycie paliwa przez śmieciarki (transport zmieszanych odpadów komunalnych) o 1,1 dm3·Mg-1. W wyniku badań stwierdzono, iż istnieje statystycznie istotna zależność pomiędzy zużyciem paliwa (dm3·Mg-1), a udziałem kursów realizowanych na terenach wiejskich (R = - 0,83).
This paper reports the analysis of transport costs for segregated municipal solid waste (MSW) collected from the Krakow city and the 13 municipalities bordering the main town of Małopolska Region. There were 4 selected vehicles (garbage trucks) analyzed (collected segregated waste from households) These vehicles have a similar work characteristics. These vehicles belong to private enterprise dealing with the waste transport. The largest share in the structure of the waste transport and collection have fuel costs (29.5%), salaries (26.7%) and cost of bags purchase (18.0%). Other costs and enterprises profit represent 25.8% of the total transport costs. The average unit cost of segregated waste transport and collection is 243.3 zł. Mg-1 and is higher by 60 zł. Mg-1 in relation to the cost of mixed waste transport. Average fuel consumption (Diesel) per 1 Mg of segregated waste is about 13.2dm3·Mg-1 and it is higher than for mixed waste by an average of 1.1 dm3·Mg-1. Furthermore there is a statistically significant dependence between the unit costs of waste transport (dm3·Mg-1) and participation of courses realized at the rural areas (R = - 0.83).

Opis:

Industrialization becomes very significant for developing countries like India having large number of population. Rapid increase in urbanization and per capita income lead to high rate of municipal solid waste generation. In recent times, E-waste and plastic waste also contribute considerably to total waste stream due to utilization of electronic and other items. These wastes may cause a potential hazard to human health or environment if any of the aspects of solid waste management is not managed effectively. In India, approach towards Solid waste management is still unscientific. Solid Waste collection efficiency in India is around 70% (Sharholy et al. 2007), while same is almost 100% in the developed countries. Even today, large portion of solid waste is dumped indiscriminately on outskirts of towns or cities without any prior treatment. This leads to groundwater contamination and increase in air pollution due to leachate percolation and release of gases respectively. Various study reveals that out of total solid waste, 80% can be utilized again either by recycling or reusing. Improper waste segregation and other factors lead recycling sector to work on outdated technology. However, plastic and paper recycling have been especially growing due to continuous increasing consumption of both the commodities. This study describes about current status of municipal solid waste management in different regions of India. It further summarizes a collective, systematic effort which improves implementation of legal frameworks, institutional arrangements, financial provisions, technology, operations management, human resource development, and public participation and awareness of Integrated SWM systems.

Opis:

In the composting process, microorganisms meet the primary role of which is related to the metabolic activity of the process of synthesis of humus. Properly made compost is characterized by a large value of fertilizer, often exceeding the fertilizer value of manure. However, in the production of compost main objective is to optimize the conditions of this process. The aim of this study was to determine the dynamics of changes in the number of selected groups of microorganisms and dehydrogenase activity levels occurring during the composting of pine bark, depending on the application of different organic additives and microbiological preparation and changes in pH and temperature. The experiment was established in 2011 in the Forest District Antonin in Wielkopolska. Composting was carried out in seven piles of pine bark supplemented with different doses of green mass of legumes, Effective Microorganisms solution and urea. During the composting process, samples were taken five times for microbiological analysis. It were analyzed number of mesophilic and thermophilic bacteria and fungi on selective substrates. Isolated colonies were used to determine the total number of tested microorganisms. Furthermore, were tested the enzymatic activity of microorganisms, determining the activity of the dehydrogenase, using the spectrophotometric method with TTC as a substrate. Also were analyzed the impact of differences in the composition of compost on the growth of microorganisms. The following terms were also tested the pH level and the temperature of the windrows. It was found that additives composted pine bark with the exception only of the preparation EM-A stimulating influence on the population growth of bacteria meso-and thermophilic composting in windrows. A particularly preferred combination proved to be a combination of the green mass of the plant with solution of Effective Microorganisms. Changes in the number of analyzed groups of microorganisms also fundamentally affect temperature changes during the composting process. During the high temperature composting piles was observed in a significant increase in the number of thermophilic bacteria and fungi. In most of the analyzed terms the largest number of thermophilic bacteria and fungi was observed in combination of pine bark, and extended to the highest dose of the green mass of the plants and EM-A. Dehydrogenase complex activity did not increase with the increase in the number of analyzed groups of microorganisms.

Opis:

The monitoring that was carried out at the landfill specialized in leachate, groundwater and surface water. There were 6 sampling sites. The observed parameters were pH, BOD₅, COD_Cr, conductivity. Leachate reached the high values in all observed parameters. Groundwater samples were collected at two monitoring wells and the sampling site (A, B, C). Surface water was collected from two sampling sites (D, E). The pH showed slightly acid values at all sampling points. The pH of surface water was slightly acid to neutral. Both BOD₅ and COD_Cr values remained stable over the reporting period. The average conductivity value at sampling points D, E remained constant. In line with the Czech National Standard ČSN 75 7221 “Classification of Surface Water Quality” sampling point D belongs to II Water Quality Class – slightly polluted water and sampling site E to Class I water quality – unpolluted water. The authors believe that the fluctuations occurring with regard to the values of certain samples were not caused by the operation of the landfill itself, but were a result of the intense agricultural activity nearby the landfill.

W 2014 r. w Polsce zebrano ogółem 10,33 mln ton odpadów komunalnych, z czego 80% pochodziło z gospodarstw domowych. Około 20% z nich zostało zebranych selektywnie. Selektywne zbieranie odpadów komunalnych stanowi istotny element właściwego zarządzania odpadami. Daje szansę przetworzenia większej ilości odpadów i ponownego ich wykorzystania. Regulacje prawne zobowiązują gminy do tworzenia punktów selektywnego zbierania odpadów komunalnych. Równie istotna jest właściwa polityka informacyjna gmin do obywateli w zakresie prawidłowego gospodarowania odpadami.
In 2014 in Poland a total of 10.33 million tons of municipal solid waste were collected, of which 80% came from households. About 20% of municipal waste was collected separately. Selective collection of municipal waste is an important element of proper waste management. It gives a chance of processing more waste and re-use it. Legal regulations require municipalities to create points of municipal waste selective collection. Equally important is the policy of information to citizens on the proper waste management.

Opis:

Discussion on counteracting the greenhouse effect focused on the reduction of CO2 emissions mainly from the fossil fuel burning. There is often forgotten that the important role in greenhouse effect play other gases, such as methane, but its production is weakly associated with the combustion of fossil fuels. The global warming potential for methane is approx. 25-fold higher than that of CO2.Methane is located at second place on the list of the substances responsible for rising the temperature of the Earth’ atmosphere. Taking into account the global action towards prevention the climate changes, a reduction of methane emissions should be enhanced. It could significantly improve the atmospheric air quality. The aim of the study was to evaluate the efficiency of bio-oxidation of methane and selected aromatic hydrocarbons emitted from municipal solid waste landfills. The research was carried out under field scale for 10 months, from early summer to early spring. An open type biofilter worked at variable loading rate of landfill gas and under different climatic conditions. Due to the low gas pressure inside the waste body, the gas suction was applied to provide a continuous gas flow to the biofilter. This was resulted in landfill gas dilution by atmospheric air migrating through the leakiness in the gas supply system. The study showed that the temperature was limiting factor in the processes of bio-oxidation of methane and monoaromatic hydrocarbons such as BTEXs in field scale biofilter. During winter season the realbed temperature fall below 0°C throughout the whole profile of the biofilter. This led to the freezing of the water contained in the soil pores, which prevented the flow of gas along the biofilter. In other seasons, where the average bed temperature ranged from 5.5 to 42.3°C, biofilter worked reaching the 100% efficiency of BTEXs removal, at average mass loading rate of 26.75 ug BTEXs m-2d-1, and 42% efficiency of methane removal at average mass loading rate of 14.6 g CH4 m-2d-1. High efficiencies of volatile organic compounds (VOCs) removal from landfill gas can be explained by dilution of gas stream entering the biofilter with the atmospheric air. Calculation of elimination capacity of particular VOCs and the evaluation of the impact of VOCs concentration on removal efficiencies was impossible due to their total oxidation in the biofilter.

Opis:

Paliwa alternatywne (RDF) znane są jako stabilne i bezpieczne źródła energii dla przemysłu cementowego i energetycznego zarówno pod względem mikrobiologicznym, jak i sanitarnym. Pomimo to w literaturze opisano wiele przypadków samozapłonu paliw alternatywnych w czasie ich magazynowania. Przeprowadzone badania wstępne wykazały, że przy zastosowaniu sita o średnicy oczka 80 mm do paliwa alternatywnego wytwarzanego ze zmieszanych odpadów komunalnych przedostają się odpady ulegające biodegradacji, w tym: papier, odpady organiczne, drewno itp. Udział tych odpadów w paliwie zawiera się w przedziale 11-29%. Znaczący udział odpadów ulegających biodegradacji w paliwie oraz mikroorganizmy, które je zasiedlają, są główną przyczyną samonagrzewania się tego źródła energii. Podstawowym celem badań była analiza procesu samonagrzewania się magazynowanego w pryzmie paliwa alternatywnego od momentu jego wytworzenia aż do czasu ustabilizowania się temperatury. Analizy przeprowadzono w instalacji mechaniczno-biologicznego przetwarzania odpadów komunalnych w Krakowie w okresie od września 2013 do sierpnia 2014 roku. W celu określenia zmian temperatury w czasie wykorzystano technikę termograficzną, a także system pomiarowy firmy APAR, składający się z 3 czujników temperatury PT100, umieszczonych na różnej głębokości pryzmy. Ponadto przeanalizowano zmiany zawartości tlenu wewnątrz pryzmy oraz wstępnie oceniono różnorodność mikroorganizmów zasiedlających paliwo. Badania wykazały, iż rozkład temperatury wewnątrz pryzmy magazynowanego paliwa nie jest jednakowy. Maksymalna osiągnięta temperatura wynosiła 76ºC. W pryzmie stwierdzono obecność grzybów pleśniowych, promieniowców oraz bakterii wegetatywnych i spoczynkowych. Wyizolowano także drobnoustroje chorobotwórcze (Staphylococcus aureus, Escherichia coli, Salmonella spp., Enterococcus faecalis i Clostridium perfringens), stanowiące zagrożenie dla zdrowia osób pracujących przy instalacji do wytwarzania paliwa alternatywnego.
Alternative fuel (RDF) has been known as a stable and safe solid-fuel (in terms of microbiological and sanitary) for cement and power plant. However, some spontaneous ignition incidents occurred during storage of RDF in certain facilities. As introductory research proves, the morphological composition of an alternative fuel manufactured from mixed municipal solid waste reveals such bio-degradable components as paper, organics, wood, etc. The share of those components in an alternative fuel (examined with the use of an 80 millimeter sifter) is in the range 11-29%. A significant share of biodegradable waste in the fuel and the high variety of microorganisms that colonize them are a major cause of self-heating is this energy source. The main aim of the study was to analyze the self-heating process in heap of alternative fuel since its manufacture until the temperature stabilizes. Analyses were carried out in the installation of mechanical - biological treatment of municipal solid waste in Krakow in the period from September 2013 to August 2014. To determine temperature changes during process, the thermographic technique was used, and the APAR measurement system consisting of three PT100 temperature sensors (placed at different depths of heap). The oxygen content inside the heap and the variety of microorganisms inhabiting RDF was analyzed too. Research has shown that the temperature distribution inside heap of stored fuel is not uniform. The presence of mold fungi, actinomycetes, as well as vegetative and spore-forming bacterial cells were found in the heap. Pathogenic microorganisms (Staphylococcus aureus, Escherichia coli, Salmonella spp., Enterococcus faecalis and Clostridium perfringens), which pose threat to the health of people working with the installation for the production of alternative fuel, were also isolated.

The objective of this study was to estimate the content of methane produced and generated by the anaerobic biodegradation of the main organic fraction of municipal solid waste from the controlled landfill of Mohammedia-Benslimane (Morocco) by three theoretical models, based on the first order decay equation: LandGEM, IPCC and TNO. To carry out this study, the quantities of solid waste buried in this landfill since its inauguration in 2012 were used and the composition of the biogas in-situ in 2020 and 2021was determined. The quantities of waste that will be buried in this landfill from 2022 to 2032 were estimated by projection.The results of the analysis of the biogas generated in this controlled landfill in 2020–2021 indicate that it is composed of 59.59% CH4, 38.9% CO2, and 0.14% O2. This result indicates that the waste is in a stable methanogenesis phase. The results obtained by using the three methodologies show that the total volume of CH4 generated during the period 2012–2021 was 32.59 Mm3 according to the IPCC model, 20.95 Mm3 according to the LandGEM model and 20.96 Mm3 according to the TNO model. The total volume of CH4 that will be produced during the period 2022–2032 has been projected to 107.48 Mm3 by the IPCC model, to 76.84 Mm3 by the LandGEM model, while the total volume of CH4 projected under the TNO method will be 67.67 Mm3. The maximum methane production will reach a value of 12.07 Mm3, 9.46 Mm3 and 7.82 Mm3 for the IPCC, LandGEM and TNO models, respectively. In 2021, the volume of methane estimated by the three models is higher than that on-site measurement by a factor of 3.5(IPCC), 2.4 (LandGEM) and 2.3 (TNO). The results clearly indicate that the three models over predict methane generations when compared to the on-site generations. According to the LandGEM methodology, the electricity estimated will reach a maximum value of 33 GWh/year in 2032.The efficient use of methane generated by this controlled landfill as a source of electrical energy in the upcoming years can be an option for the sustainable management of waste.

Opis:

Using the Hydrothermal process to reduce the volume of the Municipal Solid Waste (MSW) which is mostly organic component and to utilize the solid powder resulted as coal-like solid fuel will contribute not only to solving the MSW problem but also reducing the coal consumption in the power plant. In this study, the hydrothermal processes were conducted using a laboratory scale apparatus with MSW components as the samples. The process parameters comprised temperature, solid load, and holding time. Four components were used as representative of organics and plastics in the municipal solid waste. In this study, the experiments were done performed at various temperatures, 180 °C, 200 °C, and 220 °C inside an experimental autoclave. The results of the experiments show that the process time, the water amount and the temperature which are used in hydrothermal process, affect the proximate and ultimate compositions. The moisture and fixed carbon content decrease and the volatile matter increases, so that the calorific value of MSW increases. On the basis of the experiments, the optimum hydrothermal process parameters are feed to water ratio of 1/1 (250 g/250 ml), temperature of 180 °C, and holding time of 90 min. It also can be concluded that the hydrothermal process can be applied to MSW to produce solid fuel.

Opis:

Obowiązkiem każdej gminy w Polsce jest utworzenie stacjonarnego punktu lub punktów selektywnego zbierania odpadów komunalnych (PSZOK). Obiekty te stanowią nowy element zarządzania strumieniem stałych odpadów komunalnych, znany w krajach europejskich pod nazwą - „household waste recycling center”. Brak tego typu infrastruktury gospodarki odpadami komunalnymi na terenie wielu polskich gmin lub istnienie PSZOK-ów w wersji mobilnej, przyczynia się do powstawania dzikich wysypisk, a ponadto nie umożliwia zwiększania poziomów recyklingu i ponownego użycia niektórych grup odpadów. W pracy dokonano porównawczej oceny oddziaływania na środowisko pięciu istniejących PSZOK-ów na terenie jednego z powiatów województwa świętokrzyskiego. Ocenie poddano lokalizację, funkcjonowanie i wyposażenie tych obiektów. W analizie oddziaływania na środowisko została wykorzystana metoda RIAM (Rapid Impact Assessment Matrix). Spośród przeanalizowanych PSZOK-ów dwa otrzymały ocenę pozytywną, natomiast 3 obiekty powinny zostać zlikwidowane lub całkowicie zmodernizowane.
The duty of each municipality in Poland is to set up a stationary Municipal Solid Waste Collection Points (MSWCP). These facilities are a new element of municipal solid waste management system, known in European countries as: „household waste recycling center”. The lack of this type of municipal solid waste management infrastructure in many Polish communes or the existence of MSWCPs in the mobile version contributes to the emergence of wild dumps, and also don’t allow the increase of the levels of recycling and reuse of some groups of waste. The environmental impact assessment of five existing MSWCPs in one of the poviats of the Świętokrzyskie Voivodeship was compared in article. The location, functioning and equipment of these facilities were assessed. The RIAM (Rapid Impact Assessment Matrix) method was used for the environmental impact analysis. From among the analyzed MSWCPs, two received a positive assessment, while 3 objects should be close down or completely modernized.

The evaluation method to compare municipal solid waste management (MSWM) systems has been presented. The results of the integrated waste management model (IWM-1), were used as the input data for the analysis. The results were integrated into life cycle analysis LCA impact categories. The authors present possible to calculate categories, and calculate them for the two MSWM scenarios. Next, the system performance was compared using a multicriteria method, called analytic hierarchy process (AHP). The hierarchical preference analysis on the World Wide Web software Web HIPRE) was applied to conduct the analysis. The criteria ratios for the AHP were assumed arbitrarily based on the best knowledge of the authors. Finally, the presented sensitivity analysis showed the confidence of the obtained results and pointed out the most important assumptions of the whole analysis. The two Cracow MSWM systems were used as a case study.

Opis:

Podstawowym elementem dobrze zorganizowanego systemu gospodarowania odpadami komunalnymi jest selektywne gromadzenie odpadów. Prawidłowe segregowanie odpadów „u źródła”, (w gospodarstwie domowym), ułatwia dalsze postępowanie z odpadami, a w szczególności przekazywanie ich do procesów ponownego użycia oraz recyklingu. W 2020r. minimum 50% masy odpadów komunalnych, takich jak papier, metal, plastik i szkło, powinno zostać przygotowane do ponownego wykorzystania lub poddane recyklingowi. Odpady te pozyskiwane są z gospodarstw domowych, urzędów, biur i placówek usługowych, właśnie w wyniku zbierania ich w sposób selektywny. Celem artykułu jest przedstawienie wyników rocznej analizy struktury odpadów zbieranych selektywnie do żółtego worka na tworzywa sztuczne, ze szczególnym uwzględnieniem udziału zanieczyszczeń, a więc tych odpadów, które w tym worku nie powinny być gromadzone. Badania wykonano w firmie MIKI Recykling Sp. z o.o. w okresie od listopada 2016 do października 2017r. Analizowane odpady zostały zebrane z obszarów wiejskich (trzy gminy wiejskie). W wyniku przeprowadzonych analiz, stwierdzono, że udział zanieczyszczeń w strumieniu selektywnie zbieranych tworzyw sztucznych wynosi średnio 26,8%. Najczęściej występującymi zanieczyszczeniami były: tektura, „inne tworzywa sztuczne”, szkło i metal. Około 30% z tych zanieczyszczeń może być poddane procesom recyklingu lub odzysku, natomiast pozostały strumień należy przekazać do unieszkodliwienia. Tworzywa sztuczne nadające się do recyklingu stanowiły 73,2±9,4%. Wynik ten był nieznacznie wyższy od uzyskanego przez firmę udziału tworzyw sztucznych przekazanych do recyklingu (w tym samym okresie) oraz wyższy od średniej krajowej podawanej przez Główny Urząd Statystyczny.
The basic element of a well-organized municipal waste management system is selective waste collection. Separation of waste „at source” (eg in a household) facilitates further handling of waste, in particular transferring it to recycling and recovery. By 2020, a minimum of 50% of the municipal waste, such as paper, metal, plastic and glass, should be recycled or re-used. These wastes are collected selectively in households, offices, offices and service outlets. The aim of the article is to present the results of the analysis conducted during one year of the structure of selectively collected waste in the yellow bag dedicated for plastic waste, with particular emphasis on the share of impurities, that is all those types of waste that should not be thrown into this yellow bag. The research was carried out at MIKI Recykling Ent. from November 2016 to October 2017. Waste came from 3 rural communes. Analysis of the results of the conducted tests showed that the share of impurities in the stream of selectively collected plastics is on average 26.8%, while the most common impurities are: cardboard, “other plastics materials” and glass. About 30% of these impurities can be directed to recycling or recovery processes, while the remaining stream should be disposed. Plastics suitable for recycling accounted for 73.2±9.4%. This result was slightly higher than the share of plastics transferred for recycling obtained by the company and higher than the national average reported by the Central Statistical Office.

Opis:

The article discusses an innovative system used for aerobic biostabilisation and biological drying of solid municipal waste. A mechanical–biological process (MBT) of municipal solid waste (MSW) treatment were carried out and monitored in 5 bioreactors. A two-stage biological treatment process has been used in the investigation. In the first step an undersize fraction was subjected to the biological stabilisation for a period of 14 days as a result of which there was a decrease of loss on ignition, but not sufficient to fulfill the requirements of MBT technology. In the second stage of a biological treatment has been applied 7-days intensive bio-drying of MSW using sustained high temperatures in bioreactor. The article presents the results of the chemical composition analysis of the undersize fraction and waste after biological drying, and also the results of temperature changes, pH ratio, loss on ignition, moisture content, combustible and volatile matter content, heat of combustion and calorific value of wastes. The mass balance of the MBT of MSW with using the innovative aeration system showed that only 14.5% of waste need to be landfilled, 61.5% could be used for thermal treatment, and nearly 19% being lost in the process as CO2 and H2O.

Opis:

Municipal solid waste (MSW) compost supplied from the Istanbul Solid Waste Recycling and Composting Facility was used to amend soil samples collected within the boundaries of Istanbul. Cat grass (Dactylis glomerata cat grass) seeds were sown in the prepared samples. Plant development was observed for 90 days. pH, Cd, Cu and Ni concentrations in plant samples were measured at the end of every month. Concentrations of forms of Cd, Cu and Ni forms in soil were determined at the beginning and at the end of 90 day period (with sequential extraction). The effect of MSW compost on the transfer of Cd, Cu and Ni from the soil to the plants and the change in the forms of heavy metals in soil was determined. Results of sequential extraction showed that, adding compost into the soil changed the forms of these metals in soil. Plant uptake of Cd decreased, however, those of Ni and Cu increased. Cu concentration in plants that grew in soil with 3 wt. % of compost added reached 136.4 μg/kg.

Celem niniejszej pracy była analiza składu pierwiastkowego zanieczyszczeń chemicznych i mikrobiologicznych występujących na nasionach bobiku uprawianego w bezpośrednim otoczeniu składowiska odpadów komunalnych. Skład pierwiastkowy zanieczyszczeń chemicznych na powierzchni badanych nasion oraz w glebie analizowano metodą EDS za pomocą mikroskopu elektronowego NOVA NANO SEM s 300. Analizy mikrobiologiczne przeprowadzono metodą seryjnych rozcieńczeń. Wyniki przeprowadzonych analiz wykazały na powierzchni nasion bobiku uprawianego na obszarze i w bezpośrednim otoczeniu składowiska komunalnego obecność zarówno makro- i mikroelementów, jak i pierwiastków z grupy metali ciężkich, a także występowanie bakterii i grzybów. Wykazano, że usytuowanie poletka względem składowiska miało istotny wpływ na stwierdzone na powierzchni nasion bobiku zanieczyszczenia chemiczne i mikrobiologiczne.
The aim of the work was to evaluate the effect of municipal solid waste landfill on the chemical and microbiological contaminants present on seeds surface of horse bean grown in its vicinity. Elemental composition of chemical contaminants on the seeds surface and in the soil was analyzed with the electron microscopy NOVA NANO SEM s 300 with EDS technique. Microbiological analyzes were performed by serial dilutions. Conducted analyses revealed presence of macro and trace elements, including heavy metals, as well as the presence of bacteria and fungi on the surface of faba bean seeds grown in the area of landfill and in its immediate vicinity. It has been shown that the localization of plot to the landfill had a significant effect on chemical and microbiological contaminants identified on the seed surface of horse bean.

Opis:

Współspalanie węgla i stałych odpadów komunalnych jest zjawiskiem społecznym, stanowiącym poważne źródło emisji substancji szkodliwych do powietrza. Przeprowadzono badania porównawcze współspalania węgla kamiennego z poszczególnymi frakcjami stałych odpadów komunalnych (m.in. makulatura, PE, PCV) w kotle CO o mocy 18 kW wyposażonym w automatyczny podajnik paliwa. Badania miały na celu porównanie parametrów spalin, zawartości pyłu (popiołu lotnego) i gazowych substancji zanieczyszczających powietrze w emitowanych spalinach z danego kotła CO. Podczas spalania pobierane były próbki emitowanego pyłu oraz analizowany był w sposób ciągły skład jakościowy i ilościowy spalin – analiza chemiczna spalin obejmowała: CO₂, CO, H₂O, SO₂, NO_x. Oznaczono ponadto stężenie pyłu w spalinach. Pobrany popiół lotny został poddany oznaczeniom zawartości węgla C – organicznego, elementarnego i całkowitego, PM10 i PM2,5 oraz zawartości 16 WWA. Wyniki zostały przeanalizowane pod względem efektywności spalania, emisji głównych zanieczyszczeń (NO_x, CO, SO₂) i popiołu lotnego oraz zaadsorbowanych na jego powierzchni WWA. Średnie stężenie emitowanego pyłu wynosiło 764 mg m^-3, natomiast CO – 1944, SO2 – 1256, NO_x – 555 mg m^-3 (STP, 3% O₂, gaz suchy). Spaliny zawierały popiół lotny, ze znaczną zawartością węgla EC (średnio 31%) oraz wysokim udziałem PM10 oraz PM2,5 – odpowiednio 100 i 75% obj.
Co-combustion of coal and solid municipal waste is a social phenomenon. It constitutes an important emission source of harmful air pollutants. The comparative research was conducted. It concerned co-combustion of coal and different types of municipal solid waste (including wastepaper, PE, PVC) in the domestic CH (central heating) boiler (18-kW power) equipped with an automatic fuel feeder. The aim of this research was to compare the parameters of flue gas, content of dust (fly ash) and gaseous air pollutants in the flue gases from the CH boiler. During the combustion were taken the fly ash samples and was continuously analyzed qualitative and quantitative composition of flue gas. Chemical analysis of flue gases included: CO₂, CO, H₂O, SO₂ and NO_x. Concentration of fly ash in the flue gas was determined. The fly ash samples were analysed for the organic, elemental and total carbon, PM10 and PM2,5, and 16 PAHs content. The results were analyzed in terms of combustion efficiency, emissions of major pollutants (NO_x, CO, SO₂) and fly ash with adsorbed of PAHs on its surface. The average concentration of emitted particulate matter was 764 mg m^-3, and CO – 1944, SO₂ – 1256 NO_x – 555 mg m^-3 (STP, 3% O₂, dry gas). The flue gases contain fly ash, with a significant carbon content EC (average 31%) and a high proportion of PM10 and PM2.5 – respectively 100 and 75% by volume.

Opis:

W pracy przedstawiono wyniki badań procesów pirolizy odpadów komunalnych frakcji RDF metodą pirolizy ciągłej. Badaniom poddano próbki RDF lekkiego (folie) oraz RDF ciężkiego (odpady opakowaniowe). Proces pirolizy ciągłej prowadzono w temperaturze 850°C, w pilotażowym reaktorze pirolitycznym wyposażonym w spiralę grzejną. Podczas badań określono skład gazu pirolitycznego oraz bilans masowy produktów pirolizy. Uzyskano gaz pirolityczny o wartości opałowej około 13 MJ/m3 i zawartości CH4 około 20%obj. oraz H2 na poziomie ponad 16%obj. Wyniki badań wskazują na możliwość skojarzenia procesu pirolizy odpadów komunalnych z recyklingiem energetycznym i zastosowaniem gazu pirolitycznego jako alternatywnego źródła energii wykorzystywanego do produkcji energii elektrycznej. Uzyskany gaz pirolityczny może być alternatywnym paliwem do zasilania turbiny gazowej lub wykorzystany w kogeneracji zamiast gazu ziemnego.
This paper presents results from continuous pyrolysis process of RDF fraction from municipal waste. Samples used in this research were light RDF (plastic films) and heavy RDF (packaging waste). Pyrolysis process was performed inside a pilot pyrolysis reactor equipped with a heating screw in temperature of 850°C. Experiment allowed to determine a chemical composition of pyrolysis gas and mass balance of pyrolysis products. Lower heating value of pyrolysis gas was about 13 MJ/m3 , content of CH4 was about 20%vol and H2 was over 16%vol. Research results indicate possibility to combine the pyrolysis process of solid municipal waste with energy recycling and waste-to-energy system by using pyrolysis gas as renewable energy source for electricity production. Produced pyrolysis gas can be used, instead of natural gas, as an alternative fuel to power a gas turbine or cogeneration unit.

Opis:

In the fresh samples of municipal solid waste incineration (MSWI) bottom ash, the fractional composition of Zn, Cr and Co was investigated. The BCR method was utilised to evaluate the acid soluble and exchangeable fraction (F1), reducible fraction (F2), oxidizable fraction (F3) and residual fraction (F4). Physico-chemical parameters such as pH, dry mass, and pseudo-total metal content were also determined. The percentage of zinc in fractions was in the following order: F3 (31.8%) > F1 (30.6%) > F2 (27.8%) > F4 (9.8%), for chromium F4 (88.7%) > F3 (5.4%) > F1 (3.2%) > F2 (2.7%), and in the case of cobalt F4 (59.8%) > F1 (14.3%) > F2 (13.6%) > F3 (12.3%). Mobile metal pool (F1–F3) gathered the most of zinc (90.2%) and the least of chromium (11.3%).
