Solid Waste Management
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:
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:
In most countries, controlled landfills are currently the most common disposal method for municipal solid wastes (MSWs). Despite many benefits, the generation of heavily contaminated leachate with substantial differences in both chemical composition and flow rate represents a major drawback. The realization of this has compelled authorities to adopt ever more stringent establishment of pollution control requirements. Landfill leachate is a serious problem in the treatments of municipal solid wastes using landfills methods. This leachate is usually heavily contaminated, but little attention is paid to its treatment. Optimal treatment of leachates to completely decrease the harmful environmental impacts is today’s challenge. However, the complex composition of leachates makes it challenging to formulate general recommendations. Leachate variability, particularly over time and within sites, suggests that the most appropriate treatments are adaptable, universal, and simple. Landfill leachate is characterized by high biological and chemical oxygen demand and is usually composed of undesirable ingredients such as inorganic and organic pollutants. Landfill leachate varies with landfill age and content, decomposition methods, hydrological and climate conditions. Recirculation of leachate does not affect alterations in the degree of bio-degradability of the waste. During landfill operations, recirculation of leachate is often applied to help stabilize landfill degradation. Leachate recirculation is widely used in practical engineering, and recirculation using vertical wells is one of the more effective methods.

This paper presents a thermoeconomic analysis and assessment of a municipal solid waste power plant system in Gaziantep. The operation of an existing municipal solid waste power plant is described in detail and a thermoeconomical methodology based on exergoeconomic relations and specific exergy costing (SPECO) method is provided to allocate cost flows through subcomponents of the plant. SPECO method is based on a step by step procedure which begins from identification of energy and exergy values of all states defined in the present system through fuel (F) and product (P) approach and ends at the point of establishing related exergy based cost balance equations together with auxiliary equations. The actual exergy efficiency of the solid waste power plant is determined to be 47.84% which shows that 52.16% of the total exergy input to the plant is destroyed. The net electrical power output of the Gaziantep municipal solid waste power plant is 5.655 MW. The total cost rate of the power plant is evaluated as 18.44$/h as a result of thermoeconomic analyses.

In this study, air flow controlled incinerator (AFCI) was used to treat medical solid waste in Vietnam. The experiment was conducted with solid waste samples that was weighed approximately 2.1–3.3 kg/h and had moisture content of 2.8–11.7%. The results showed that an increase in the air flow rate during the drying process accelerated the combustion time by 10–20%, and the optimal air low rate was 1.1 m/s. The combustion time varied from 0–45 min. The highest temperatures recorded in the drying chamber, carbonisation chamber and combustion chamber after 25–35 min of operation were varied from 195o C, 775o C and 1275o C, respectively. The temperature of the stack was from 33–68o C after the treatment by the wet scrubber using 20% NaOH solution. The combustion capacity was 77.3–87.5%. The experimental results revealed the AFCI process advantages including low operation cost and suitability for treating hazardous waste on a small scale.

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:
Corrosion which seriously affects the quality and functionality of steel can be reduced by hot dip aluminizing which involves dipping substrate to a molten aluminum bath. Thus, this study aimed to produce hot dip aluminized coating for steel using discarded soda cans. A total of 80 steel nails with length of 65.62±0.56 mm were used wherein 40 nails were intended for the hot dip aluminizing process at 650-700 °C with an average coating mass and thickness of 547 g/m2 and 170 μm, respectively, with density of 2.627 g/cm3 following ASTM standards. Compared to the non-coated setups, the fabricated aluminum coating reduced 0.178g and 0.092g of corrosion products accumulation after immersions on H2O2 and NaCl solutions for 7 days and 4 weeks, respectively. Optical analysis of surface and cross sections of the coated samples showed less pitting, and corrosion products. Aluminum coating tends to pit that starts from small cracks and fractures when immersed in corrosive medium. Moreover, scanning electron microscopy showed that the coated nail sample experienced minimal corrosion in the form of thin cracks compared to non-coated nails which had relatively rough surface as result of heavy corrosion. In addition, t-test showed significant difference between the accumulated corrosion products’ weights of coated and non-coated setups after immersing in NaCl (t = -13.801; p = 0.000) and H2O2 (t = -31.005; p = 0.000) wherein less corrosion product was obtained by the coated set-up (x̅ = 0.036 (H2O2) and x̅ = 0.028 (NaCl)). Thus, the results proved that the produced aluminized coating from waste soda cans provides a significant corrosion protection on the steel substrates.

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.

Objectives: This study aims to assess the frequency and factors relevant to metabolic syndrome in workers employed in the collection and disposal of solid waste sector. Materials and Methods: This cross-sectional study was conducted in the major solid waste collecting and disposal company named İSTAÇ AŞ (İstanbul Environmental Protection and Waste Processing Corporation) in Istanbul, Turkey. All 715 male employees of the company were included in the study without sampling. The study was completed with 619 subjects. Since it was a small group, female workers were not taken into account in the study. Metabolic syndrome frequency was investigated according to the NCEP-ATP III criteria including the levels of systolic and diastolic blood pressure, waist perimeter, HDL, triglyceride, fasting blood glucose values. Results: Metabolic syndrome was present in 40.9% of participating employees. Metabolic syndrome was more common in those working in the excavation field (54.0%), such as caterpillar operators (56.5%), and less common in employees working in administrative offices, such as office staff or managers, who were under 35 years old and who had been working for less than 10 years (p < 0.05). Employees working in work stations other than administrative offices had a 2.60 times higher risk compared to those working in administrative offices. Conclusions: Metabolic syndrome may be related to work station, job, age and period worked by the subjects.

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.

Opis:
Increased waste generation due to population growth and increasing consumption patterns cause pollution, including pollution in global scale due to the emission of methane (CH4) and carbon dioxide (CO2) from the waste in the landfill. The study purposed to analyze the GHG (Green House Gases) emission generated by solid waste management in Malang in 2012 and in the next 10 years through the application of waste recycling from upstream to downstream. The production of methane (CH4) in landfill were analyzed using the model equations developed by IPPC (2001) and the reduction of the GHG from recycling were analyzed using GHG emission factors. Dynamic model of the GHG emission was developed to analyze and to predict GHG emission from recycling and dumping activity. The GHG emissions of waste management in 2012 (Scenario 1) is 192,291.19 tCO2e and in the next 10 years is 254,548.93 tCO2e (>32.19%). Application of Scenario 2 and Scenario 3 in the next 10 years produces GHG emission 134,290.38 tCO2e (<30.16%) and 37,741.56 tCO2e (<80.37%).

Opis:
Post-mining soil and solid waste from the silica sand refining industry is widespread and the potential long-term impact of toxic metals and metalloids is a significant and under-appreciated issue. This study presents the characteristics of post-mining soil and solid waste resulting from silica sand purification to observe its physical, chemical, and biological composition. Analysis of the physical properties was carried out with reference to ASTM 112-10 and the results show that post-mining soil contains 36.95% sand, 18.80% clay, and 42.74% silt, with coefficients of permeability and porosity of 0.69×10-6 cm•s-1 and 35.84%, respectively. Meanwhile, the solid waste contains 43.35% sand, 35.96% clay, and 20.68% silt with coefficients of permeability and porosity of 1.49×10-6 cm•s-1 and 51.12%. The overall mineralogy and morphology of both samples showed that they have the same chemical composition as gehlenite (Ca2Al2SiO7), spinel (MgAl2O4), akermanite (Ca2MgSi2O7), monticellite (CaMgSiO4), aluminum oxide (Al2O3), magnetite (Fe3O4), and hematite (Fe2O3) supports this data. The chemical composition of both samples is SiO2, Al2O3, CaO, and MgO, but the post-mining soil has lower heavy metal and nutrient contents compared to solid waste. Meanwhile, solid waste has a high content of heavy metals and nutrients due to washing and bonding from the silica sand purification process. The abundance of bacteria (Colony Forming Unit) for the 10-4 and 10-5 dilutions in post-mining soil was 1.59×103and not detected, while in the solid waste, 4.10×105 and 1.64×105 were found, respectively. This study can be used as base values for modifying the two samples, which can be applied in mining land reclamation.

Opis:
Waste disposal in landfill sites causes a potential hazard for the human health, as they release substantial amounts of gas, odours and pollutants to the environment. There have been vast reductions in the volume of waste being landfilled in many European countries and a reduction in the number of illegal landfills. The European Parliament’s laws obliged the Member States to amend the national waste law; the main objectives of the implemented directives are to create the conditions for the prevention of excessive waste. Directive 2008/98/EC establishes, as a goal for 2020, that waste reuse and recycling reach 50% of the total waste produced. Poland, having joined the European Union, committed itself to implementing many changes related to waste management. The amendment of the law on the maintenance of cleanliness and order in the municipalities imposed new obligations regarding the waste management (WM) on the local government and residents. By adopting a municipal waste management system, the selected municipality made all its residents responsible for their waste. However, the fact of introducing changes does not solve the waste problem. The implementation of EU directives and the development of strategic documents such as the National Waste Management Plan (NWMP) have made a clear change in the WM approach. One of the changes was the establishment of selective collection of municipal selective waste (MSW), with the issue of collecting the waste by the residents being a priority. This work describes the legal context of selective collection of MSW as one of the most effective means of reducing the amount of waste being landfilled.

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:
This paper presents a review of literature dealing with the combustion of a single solid fuel particle, as well as a model of combustion of solid waste particle. Two cases were analysed: • Heating of a single fuel particle without chemical reaction, • Heating of a single fuel particle with endothermic and exothermic reactions. • The degassing process was omitted in this analysis. The first version of calculation was dedicated to the heating process of a sphere of diameter 2R with no inner heat sources and with uniform initial temperature tp placed in the surrounding volume of temperature tos. The assumption was that the convection heat transfer coefficient was known and constant. The calculation procedure was based on the paper [2]. Following parameters of a solid waste particle were taken into account: density, heat condustion coefficient, heat capacity, and their influence on the heating time and temperature was shown. It was observed that the increase of heat capacity and density of the particle increases the heating time while the increase of heat conduction coefficient leads to the opposite effect [3]. The influence of heat conduction coefficient on the temperature history inside the particle is shown on Fig.1 (apparent density 2000kg/m3, heat capacity 1000 J/kg K, volume temperature 9000C).
Praca obejmuje przeglad literaturowy modeli spalania pojedynczego ziarna paliwa stałego wraz z opracowaniem modelu spalania pojedynczego ziarna paliwa stałego formowanego na bazie odpadów stałych w dwóch wariantach: • nagrzewanie pojedynczego ziarna paliwa bez reakcji chemicznej, • nagrzewania pojedynczego ziarna z reakcja endotermiczna i egzotermiczna. W obu przypadkach proces odgazowania został pominiety. Pierwszy wariant obliczen obejmował przypadek nagrzewania jednorodnej kuli bez wewnetrznych zródeł ciepła, o poczatkowej wyrównanej temperaturze przeniesionej nagle w osrodku o danej temperaturze przy czym znany był współczynnik wnikania ciepła 1. . W obliczeniach symulowano wpływ zmian własciwosci fizyko-chemicznych paliwa takich jak: gestosc, współczynnik przewodzenia ciepła i pojemnosc cieplna (wielkosci te zostały zawarte w przedziałach odpowiadajacych wartosciom dla ró6nych odpadów) na czas i temperature nagrzewania. Podczas rozwa6ania nagrzewania ziarna bez reakcji chemicznej brano pod uwage jedynie przepływ ciepła obejmujacy wnikanie ciepła od osrodka do ziarna oraz przewodzenie ciepła w głab analizowanej czastki. W wariancie drugim w procesie wnikania ciepła uwzglednione zostały ponadto reakcje wystepujace na powierzchni ziarna i wewnatrz pór. Bilans cieplny został wzbogacony poprzez wprowadzenie entalpii reakcji dla dwóch odrebnych przypadków: reakcji egzotermicznej i endotermicznej.

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.
