Composting is a natural biological process which results in the degradation of organic waste to a stable end product, commonly referred to as compost, which can be utilized for various agricultural purposes. Increasing landfill costs and regulations which limit many types of waste accepted at landfills has increased interest in composting as a component of waste management (Goldstein and Spence...

In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...

An increased international effort to reduce the incidence of malaria around the globe while reducing reliance on DDT was announced 6 May 2009 at the fourth meeting of the Conference to the Parties to the Stockholm Convention on Persistent Organic Pollutants (POPs). With funding of more than US$70 million, the United Nations Environment Programme and the World Health Organization have launched 1...

On the basis of three years' intensive observation of the community and interactions at the Love Canal in Niagara Falls, NY, the present study addresses the psychosocial problem of creating and maintaining trust between the residents of an area contaminated by toxic waste materials and the government-sponsored scientific researchers and other health professionals who worked and studied there (t...

Hazardous solid wastes may pose a serious risk to human health and to the environment, if not managed appropriately and disposed of safely. In this study, the effective stabilization of tannery sludge, a toxic industrial solid waste produced from the physico-chemical treatment of tannery wastewaters, was examined by the addition of ladle furnace slag (LFS), another industrial solid waste. Moreo...

The quality of the waste sampling procedure and chemical analysis was evaluated in a research program on characterization of organic waste obtained after disc screening of source-separated organic household waste. The sampling procedures focused on a truckload of waste and involved several steps of subsampling including shredding, mixing, blending, high-speed-blending, drying and milling prior ...

he 1980s brought changing trends into the waste market with increased reclamation, T recycling and waste minimization efforts. Adapting proven tcchnologies has aided in moving these three forms of waste managcment forward. A t EncycleITexas, Inc. (ETI), the fundamental objcctive of recycling is to convert hazardous waste into products. Founded in 1988, ET1 recycles metalbearing waste streams to...

Biogas energy has got importance in the field of energy engineering because of its attractive features. Biogas is produced from different types of waste materials by the process of Anaerobic Digestion. This paper gives the insight of Anaerobic Digestion process and different pretreatment methods used in various experimental research works. Flower waste is also a potential source of biogas energ...

BACKGROUND Healthcare waste is produced from various therapeutic procedures performed in hospitals, such as chemotherapy, dialysis, surgery, delivery, resection of gangrenous organs, autopsy, biopsy, injections, etc. These result in the production of non-hazardous waste (75-95%) and hazardous waste (10-25%), such as sharps, infectious, chemical, pharmaceutical, radioactive waste, and pressurize...

This paper reviews documented environmental effects experience from the disposal of solid waste materials in the U.S. Selected case histories are discussed that illustrate waste migration and its actual or potential effects on human or environmental health. Principal conclusions resulting from this review were: solid waste materials do migrate beyond the geometric confines of the initial placem...
