Abstract

Waste management is a new concept for most of the Asian countries including India. The lack of financial and technical resources and regulatory control for the management of hazardous waste in the past has led to the unscientific disposal of hazardous waste in India. Now a days urbanization not only concentrates waste but also raises generation rates. New and expensive technologies are being pushed to deal with our urban waste problem ignoring their environmental and social implications. Hazardous waste can be classified into solid, liquid, gases and sludge waste. There are various methods of disposal of waste management. Disposing the waste in a landfill involves burying the waste. In incineration the solid organic wastes are subjected to combustion so as to convert them into residue and gaseous products. In recycling, the collection and reuse of waste materials are done such as empty beverage containers. Biological reprocessing in which waste materials that are organic in nature such as plant material, food scraps can be recycled using biological compositing and digestion process to decompose the organic matter. Energy recovery as well as avoidance and reduction methods are also the other ways of disposal.
