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:
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.

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:
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.

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:
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:
Traditional markets in Malang Regency are divided into four classes with particular classifications. The traditional market solid waste research aims to show the environmental impact of solid waste management efforts using life cycle assessment (LCA) and selected scenarios to reduce solid waste sustainably. The planned management follows four scenarios: Scenario 0 represents the baseline scenario. Scenario 1 assumes that non-composted solid waste recycling is carried out. Scenario 2 assumes that composting takes place. Finally, Scenario 3 assumes that non-composted solid waste recycling and composting are integrative ely carried out by building a reduced reuse recycle solid waste treatment facility (TPS 3R) near the market. The environmental impact analysis was carried out with various impact categories (carcinogens, respiratory organics, respiratory inorganics, climate change, radiation, ozone layer, ecotoxicity, acidification/eutrophication, land use, minerals, and fossil fuels). The results show that the smallest environmental impact is in Scenario 3 in most classes, namely the scenario where non-composted solid waste was integrative ely recycled and composted.

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.

Opis:
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.

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:
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.

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.
