21. Rapid developmental activities over the last few decades and the consequent increase in urbanization in our country has led to an ever growing problem of disposal of waste of all types. The waste generated are commonly classified based on characteristics in terms of its impacts on the environment. The hazardous waste such as chemical and the specific biological one is of great concern due to its toxicity even at low levels and some are greatly infectious. The disposal of these HW requires very specialized methods. These HW may be gaseous, liquid and solids, which may be reactive, toxic, flammable, corrosive, radio-active and particularly of biological origin may be infectious. All such wastes are directly or indirectly involved in health and environmental hazards.
In order to tackle the problem of hazardous waste, authorities have identified types of industries generating HW. These industries store and transport as per the guidelines and unload at the specific designated disposal sites. There are also well defined criteria for selection and preparation of the disposal sites. The Government of India has issued management and handling rules for such chemical and bio-chemical waste. There are various categories of HW and the steps involved in its management. The steps involved in this process also include the EIA in the selection and preparation of disposal sites.
