Even though solid waste management has become a major public health and environmental concern in urban areas of Ethiopia, only 2% of the population receive solid waste management services. The primary objective of this study is to assess solid waste management practices of Bahir Dar City. The technique of multistage random sampling has been employed to draw 350 households for this study, with b...

Efficient Solid waste utilization is a challenging task. In rural areas organic wastes like cattle waste is available in abundant, which is not utilized in the valuable forms and in urban areas it is disposed off in an improper manner. In this study biogas primarily from cattle waste was generated by using a fabricated anaerobic biogas digester. The methane is easily separated from biogas by re...

By mechanical-biological treatment (MBT) of residual municipal solid waste the behaviour of landfills can be significantly improved. After MBT the organic content (COD and BOD5), total organic carbon, and total nitrogen in the leachate, as well as the gas production rate, are reduced to values lower than 90% of the fresh untreated waste. The volume of the stabilized material to be disposed on l...

Waste generation has increased considerably worldwide in the last few decades. Solid wastes encompass the heterogeneous mass of throwaways from the urban community as well as the homogeneous accumulations of agricultural, industrial and mineral wastes. Waste generated from biomedical activities represents a real problem of living nature and human world. A proper waste management system should b...

Research Objective — This project focuses on the development of reliable theoretical and efficient computational descriptions of the chemistry of high-level waste simulants in highly concentrated solution and the experimental validation of this approach. It is an extension of previous work which: a) Determined the mechanism of H2 formation in waste simulants allowing quantitative prediction of ...

The disposal of municipal solid waste into the landfills has been recognized as the major source of soil, surface water and groundwater contamination. Municipal solid waste disposal site for the city of Ludhiana, in Punjab, India, has become an overflowing landfill because of the indiscriminate dumping of solid waste at the site. The leachate produced by landfilling site contains a large amount...

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...

Background & Aims of the Study: Considering the importance of solid waste disposal and the possibility of conversion them into rich organic fertilizers, the objectives of this study were to evaluation of effect of vermicomposting process (VP) on organic matter of cattle manure compost (CMC) and municipal solid waste compost (MSWC) by record changes of the elemental contents of C, N, H, S, and O...

This article investigated 36 administrative villages in Heilongjiang Province, Jilin Province and Liaoning Province. The questionnaires ask about the issuance of local rural sanitation, solid waste, chemical fertilizers, pesticides, the use of plastic film and environmental protection activities. Statistics based on the questionnaires are as follows: Organic Waste is the major part of rural sol...

The increasing solid waste generated in the Accra metropolis has not been accompanied with adequate sanitation facilities and management programs. Notable among the waste management problems is inadequate operational funding from the municipality’s budget allocation for the collection and disposal processes. The disposal methods mostly depend on the obsolete dumping with the associated environm...
