Currently, the management of urban waste streams in developing countries is not optimized yet, and in many cases these wastes are disposed untreated in open dumps. This fact causes serious environmental and health problems due to the presence of contaminants and pathogens. Frequently, the use of specific low-cost strategies reduces the total amount of wastes. These strategies are mainly associa...

The scientific disposal of Municipal Solid Waste (MSW) is of great significance to the urban ecological environment and the residents’ health. Taking into account the economic, technical, environmental, social indicators, as well as their subindicators, analyzing fourteen evaluation factors, the paper discusses four kinds of disposal methods of MSW using AHP and Fuzzy comprehensive evaluation. ...

This paper provides an overview of solid waste management by local authorities in the Sucre municipality in Caracas, Venezuela. Sucre is currently faced with serious demographic, economic, social, urban, and administrative challenges in solid waste management. The municipality, called Petare, has one of the largest slums in Latin America. It is estimated that more than a million people live in ...

Chromite ore processing residue occurs at over 130 sites in Hudson County, New Jersey. Many of these sites are in urban residential areas. This waste is a result of 70 years of chromate and bichromate chemical manufacturing. At least 15% of the sites contain total chromium concentrations greater than 10,000 mg/kg, with hexavalent content ranging from about 1 to 50%. Continuing leaching of this ...

Rural areas of Cambodia have no safe waste management strategies for household latrine waste. Household application of lime (calcium hydroxide, Ca(OH)2) would enable households to treat waste easily on-site and significantly reduce the risk of latrine sludge causing negative impacts on human health and the environment, whilst transforming latrines into incubators of a valuable agricultural addi...

municipal solid waste management (mswm) has become the greatest problem facing many urban and semi-urban areas in nigeria, although to varying degrees. this study suggests the various steps and approaches to combat the menace in akure in the southwest zone of nigeria. such approaches include creation of special agencies for the collection, recycling and conversion of municipal solid waste (msw)...

Rapid urban growth induces global environmental change, particularly when it comes to production, consumption, and the generation of waste. According to the United Nations, most of the world's population will be living in cities by the year 2030. In developing countries, urban agglomerations are growing at twice the rate of overall population growth. Each day, approximately 160,000 people migra...

Overpopulation is no doubt worldwide concern as it brings different problems to urbanization process as well as environment. Waste is number one side product of overpopulation. Waste generation is ever increasing in both urban and suburban area and has led to many environmental issues. Many of the waste generated have potential to be transformed into value added products. By recycling, reusing ...

Porcelain and plastic materials constitute bulk of household wastes. Owing to resistibility and slow degradability that accounts for higher residence time, these materials qualify as potential hazardous wastes. Retention of water permits these wastes to form a congenial biotope for the breeding of different vector mosquitoes. Thus porcelain and plastic wastes pose a risk from public health view...
