Recovery of energy from MSW by combustion in Waste-to-Energy (WTE) plants reduces land filling and air/water emissions, and also lessens dependence on fossil fuels for power generation. The objective of this study was to assess the potential of gasification processes as an alternative to the combustion of MSW. Gasification uses a relatively small amount of oxygen or water vapor to convert the o...

Municipal domestic waste is the most complex one among the solid wastes. Its improper disposal will easily cause serious environmental pollution, occupy substantial landfill and waste the recyclable resources. System dynamics methodology presents special merits in the study of the municipal waste management. In this paper, 16 study achievements of the system dynamics are summarized with regard ...

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 ...

Solid waste is one of the unavoidable products of every society that necessitates the establishment of municipal solid waste management system. Because of variability in quantity and composition of municipal solid wastes, several management scenarios are considered. Assessing the environmental impacts of the life cycle of these scenarios will have a significant role in reducing and resolving ur...

The management of municipal solid waste (MSW) in China is facing urgent problems with rapid industrialization and urbanization. This article focused on the status of Hangzhou, capital city of Zhejiang province, China. The regulations, policies, implementation, barriers and solutions about source separation, separate collection, clean & direct transportation, treatment and disposal were introduc...

Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is abundant in some parts of Europe and Turkey as well as Western United States is sepiolite. A laboratory study was undertaken to investigate the feasibility of sepiolite as a liner ...

Two-pot experiments with ryegrass and wheat plants were conducted in a Cambic Arenosol to test the reliability of N fate predicted by incubation experiments previously performed, with the same soil, to assess potentially mineralizable nitrogen from six organic wastes (municipal solid waste compost, secondary pulp mill sludge, horn meal, poultry manure, solid phase from pig slurry and composted ...

Fig. 1. Relationship between waste and raw materials in the production and use of building materials; the lines illustrating areas of interest for Waste Management are emphasized. An ever-increasing number of papers focusing on the use of waste as an alternative material in the production of building materials is being submitted to Waste Management. Indeed, the wide variety of waste components ...
