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.

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:
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 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:
In an attempt to reduce waste originating from end-of-life vehicles (ELVs) which is becoming a serious environmental problem, the European Union enforced in 2000 the End-of-Life Vehicles Directive 2000/53/EC. Each European member state has to comply with the achievement of the following recycling and recovery targets: 80% and 85% by 2006 and increasing to 85% and 95%, respectively, by 2015. The required and achieved recovery and recycling targets for ELVs in Poland in 2011 have been discussed and compared. The data shows that the achieved targets of recovery and recycling were about 82% and 80%, respectively. Therefore, the barrier factors affecting management of ELVs have been identified and the route useful to comply ELVs recovery and recycling in Poland and for other developing countries has been presented. The experience shows that this goal could be achieved by energy recovery and materials recycling of automotive shredder residue.

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.
