life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...

This article highlights the problems of solid waste management in the city of Guwahati. The institutional responsibility of solid waste disposal system is assigned to the Guwahati Municipal Corporation. But the service provided by the corporation is neither efficient nor sufficient. This has created enormous problem in the city. Therefore, an attempt has been made in this article to examine peo...

Waste-to-energy (WtE) facilities have been established worldwide as a sustainable method for the disposal of residual waste. In the present study the following competing WtE systems were compared: (1) municipal solid waste incinerators (MSWIs) with energy recovery; (2) co-incineration of waste in old lignite or coal-fired power plants; (3) substitute [refuse-derived fuel (RDF)] incinerators wit...

Degradation of urban environment and health hazard is directly associated with the unscientific handling of Municipal solid waste of India. Urbanization also contribute intensify Municipal solid waste generation. Source segregation of solid waste not only the fact to converge but also possible in maximum resource recovery from the waste. Waste management is a problem due to the ineffective mana...

organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...

Waste materials are common problem in modern living. Waste accumulates from number of sources including domestic, industrial, commercial, construction and demolition activity. A significant portion of municipality waste is construction related. Proper management of construction and demolition waste is important or else it will get mixed with municipal waste. This type of mixing leads to cutting...

background: developing cities like khulna, the third largest metropolitan city in bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (ngos) and community-based organizations (cbos) in municipal solid waste (msw) management. methods: a survey ...

Each day, 15,000 tons of sludge solids are removed from U.S. wastewater treatment plants. A combination of events has caused disposal of this sludge to build up to a major problem for an increasing number of communities. Municipal sanitary wastewater contains about 0.35 pounds of dry solids per person per day. Added to this load are various commercial and industrial wastes. Ever-greater quantit...

A complex mechanical-biological waste treatment plant designed for the processing of mixed municipal solid wastes (MSW) and source-selected organic fraction of municipal solid wastes (OFMSW) has been studied by using stability indices related to aerobic (respiration index, RI) and anaerobic conditions (biochemical methane potential, BMP). Several selected stages of the plant have been character...

This paper presents to demonstrate a new tool for designing integrated municipal solid waste to energy systems in the urban environment, in determining how municipal solid waste can be used to generate energy rather than being disposed of in landfills and whether it will be economical to do so. A tool has been developed to design energy system in urban environment looking at the impact of urban...
