    Opis:
    Municipal solid waste (MSW) contains mineral materials which are seldom considered as a potential resource. Currently, the waste management sector pays attention to recyclable parts, biodegradable material, waste-to-energy fraction, and residues after waste reuse and recycle. In contrast, this study focus as on the mineral matter in MSW. The aim was to analyze and discuss the sources of mineral matter in MSW, the impact which the minerals have on waste management technologies, and finally, the possibility to recycle the mineral matter. The contribution of inorganic matter in the MSW stream is significant (about 20 wt.%). In the years 2012–2015, the average content of mineral matter in mixed MSW in Poland ranged from 16 wt.% to 36 wt.%, and the content of organic in MSW ranged from 20 wt.% to 42 wt.%. Minerals in MSW have rather negative impact on waste management technologies and their final products, and can be sorted out from the MSW stream, either in the households or in a central sorting line. However, in central collection and separation systems it is difficult to obtain a mineral matter fraction in subsequent processing steps due to technological limitations (inefficiency of devices), high degree of waste fragmentation and pollution of mineral matter with other waste. This indicates a hampered ability to separate minerals in a form available for reuse, so an effective system should be based on improved segregation at the source.

    Opis:
    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:
    More than 60% of the waste dumps in India are within 500 m from the communities. The odor impact from these sites may be the sole criterion to prioritize these sites for closure/remediation. The existing rating systems do not consider odor impact in their assessment. A new system, proposed in the study, employs seven parameters derived from the literature review and selects their ratings based on data obtained from a survey of waste dumps in Indian cities having population more than one million and expert judgment. Application of the new system to the waste sites with continuously varying characteristics shows that the scores are spread over the full range of 0–1000 and have minimum clustering. The sensitivity analysis of the new system shows that the system exhibits medium to high sensitivity to five out of seven parameters employed in the system. The odor impact ratings for the fifteen waste dumps from the new system prioritize these dumps into three categories for remedial action and help suggesting a particular cover alternative for these dumps.

    Opis:
    The bottom ash from municipal solid waste incineration is the most important by-product, in terms of energy recovery from municipal solid waste. Safe treatment and reuse of this bottom ash in construction materials is one of the ways of its effective use. The specific use precedes the study of the properties of the bottom ash from municipal solid waste incineration. In this study, samples of bottom ash were examined via sieve analysis, basic chemical parameters, ecotoxicological property analysis and determination of heavy metals (As, Cd, Cr, Cu, Pb, Ni, Zn). The sieve analyses of samples showed different contents of individual fractions. Ecotoxicological tests for acute toxicity on Daphnia magna in the raw aqueous extract showed positive results mortality of all individuals after 24 hours. The toxic effect of bottom ash was confirmed by the content of heavy metals.

    Opis:
    Khulna is the third largest metropolitan city in Bangladesh and a centre with intensive commercial and industrial activities. Rapid urbanization and increased migration of people from rural and coastal areas has put tremendous pressure on its existing solid waste management. The status of the existing municipal solid waste (MSW) management tiers such as generation, source storage, collection, on-site storage, transportation, and open dumping has been identified in this study. The daily generation of MSW is estimated as 520 Mg, of which food and vegetable wastes are the main components (79% on average). The major source of generated MSW is residential areas, which is 85.87% of total generation, whereas 11.60% in commercial areas, 1.02% in institutional areas, 0.55% in street sweeps and 0.96% in other areas. About 50% of total generated waste is disposed daily to the dumping site and the rest remains uncollected and unmanaged. Non-governmental organizations and community based organizations play an important role in primary collection, composting of organic wastes and medical waste management.

    The work provides an overview of methods of waste collection and treatment in Poland and the Czech Republic. Differences ( in contrast to Poland, MBT technology is not used in the Czech Republic and only one incineration plant works) and similarities (similar share of waste management methods, the comparable mass of generated municipal solid waste per capita and similarly low sorting rate) between both countries have been indicated focusing on various fractions of municipal solid wastes as well as the dominant system of their management. SWOT analysis focused on the municipal solid waste management of both countries has been created. In Poland, the proportion between small amounts of waste collected selectively and the mass of waste sent to landfills is not satisfactory. In the Czech Republic, lots of municipal solid waste is deposited in landfills.

    Opis:
    An overview of municipal solid waste management (MSWM) in Poland has been presented. The processes of waste generation and composition have been described and a comprehensive review of MSWM in Poland has been provided, covering some of the important aspects of waste management, such as the current status of waste collection, transport and disposal in Poland. An additional aim of the present work was to identify the potential barriers and the factors affecting waste management as well as provide recommendations for system improvement in Poland and other similar developing countries. An analysis shows that the state of municipal solid waste (MSW) management in Poland is not yet as developed as in many other EU countries. Landfilling is still the predominant method used for the disposal of MSW. Composting and incineration are also used but refer only to a small percentage of the total. According to the latest data (31st December 2014), around 84% of MSW was collected and transported and that ca. 53% was disposed of in landfill, ca. 7% was incinerated at waste-to-energy plants, ca. 11% was treated at organic waste recovery plants and 23% was delivered to sorting. The average generation rate of MSW was 293 kg/capita/year. Generally, recycling in Poland is on the increase, especially concerning easily collectable and recyclable materials such as paper, plastics, glass and metals. Around 37% of MSW collected selectively is recycled.

    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:
    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.

    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:
    At Lawspet area in Puducherry, India, a unique situation of co-disposal of solid waste dumping and secondary wastewater disposal on land, prevails simultaneously within the same campus. So an attempt is made to assess the combined effect of this co-disposal on the environmental quality and pollution effects on groundwater quality with a view to correctly monitor the situation. Multivariate statistical analysis like hierarchical cluster analysis (HCA) and discriminant analysis (DA) were employed. HCA was performed on borewells, physiochemical parameters and seasons. Borewell clustering identified four clusters illustrating varying degree of groundwater contamination. In parameter clustering, two major clusters were formed indicating hardness and anthropogenic components. Temporal clustering identified three major clusters indicating pre-monsoon, monsoon and post-monsoon. Discriminant analysis revealed nine significant parameters which discriminate four clusters qualitatively affording 86% correct assignation to discriminate among the clusters. Also three major components viz. anthropogenic, hardness and geogenic responsible for groundwater quality in the study area were identified. Conclusively the investigation revealed that the direction of the contaminant transport is towards the southeast direction of the study area, where all the borewells (100%) are affected.

    Opis:
    The feasibility of various composts to operate as sorbents for heavy metals (Cu and Zn) removal from wastewater has been evaluated. Three commercial composts obtained from municipal solid wastes (MWS), sludge sewage (SS) and poultry manure (PM) were selected as potential sorbents. Kinetic and equilibrium tests were conducted in order to assess the equilibrium conditions to remove metals from aqueous samples. For all composts, the maximum time necessary to reach the equilibrium was 240 min. The Freundlich and Langmuir isotherm models were found to fit the sorption data. The SS compost proved to be the one with highest removal capability for both assessed metals, while MWS compost showed to be the less suitable for this purpose. These results can be explained in terms of the compost surface properties, namely, with the cation exchange capacity.

    One of the major problems human beings are confronted with in urban setting is the removal of urban waste. This problem has persuaded the urban authorities to use various tools such as Geographic Information System (GIS) to locate landfills. To do that, Sloan Digital Sky Survey (SDSS) has been used in which or multi-criteria decision making (MCDM) methods and GIS are combined. The selection of the burial place and landfill has great importance and different criteria must be considered. SDSS, using MCDM is able to investigate locating landfill using various criteria simultaneously and it determines its importance. This research aims at presenting suitable solution through using computer and GIS related to solid urban waste and their locating in Hamadan based on standard criteria. A comprehensive model based on GIS, to get the suitable burial place and landfill can help to save time and cost. The model of locating burial place of urban solid waste has been presented.

    Opis:
    The methodology of life cycle assessment (LCA) is a valuable tool for identifying and assessing the environmental impacts caused by waste management scenarios. The aim of this study was to perform a comparative LCA of two scenarios of municipal waste management system in Krakow, Poland. The assessment is limited to residual (mixed) waste. Under the former scenario, residual waste is landfilled at a well-equipped facility, while under the latter scenario, residual waste is incinerated in a thermal treatment plant with energy recovery. Landfilling represents a real situation for 2010, when all residual waste was landfilled, incinerating expresses the plan for 2016. The elements of the scenarios such as collection and treatments of separately collected waste are excluded from the system boundaries. The modeling of the environmental impact is done by the EASETECH model, employing EDIP 2003 methodology. The final results are expressed in person equivalent (PE) units. Both scenarios have negative impacts on the environment, however the impact for incineration is much lower than for landfilling. In respect of landfilling, the significant impact categories are photochemical ozone formation, global warming, eutrophication and human toxicity. Regarding incineration, significant impact categories include eutrophication, photochemical zone formation, acidification and human toxicity.

    Opis:
    The viability of partial replacement of biomass feedstock by the refuse derived fuel (RDF) produced from the local municipal waste management facility was investigated. Therefore, over two years, several samples of the rejected fractions from the selective collection operations and the mechanical and biological treatment were collected at the waste management facility. These samples were characterized to evaluate the physical composition, proximate analysis, ultimate analysis, alkali metal and trace metal content, calorific, and chlorine contents. All data were statistically analyzed. Several important differences were found between the rejected fractions and biomass, namely moisture, volatile matter, and fixed carbon content. However, the calorific value is like the expected from common wood or forest wastes. Trace and hazardous elements were found to be below the standard for RDF. After the statistical analysis, it was found that not all parameters had a normal distribution. Non-parametric tests were performed and for all the parameters analyzed only moisture content, nitrogen, and hydrogen show to be dependent on the waste source. Overall, the results point out the feasibility to prepare RDF from rejected fractions to use as co-fuel in a biomass power plant.
