This document discusses the disposal of hazardous waste materials. It notes that hazardous waste comes from many sources and can be in different forms, and that more than 400 million tons are produced annually. It outlines rules for managing hazardous waste and the challenges of hazardous waste production, transportation, storage, and different disposal methods like landfills, incineration, and recycling. The goal of hazardous waste management is to minimize harm to human health and the environment.

DEPARTMENT OF CIVIL ENGINEERING Paper Presentation On DISPOSAL OF HAZARDOUS WASTE MATERIALS Presented By, T. RAJA RAJAN
 Hazardous wastes found in different physical states such as gaseous, liquids, or solids.  Worldwide, the United Nations Environmental Programme (UNEP) estimated that more than 400 million tons of hazardous wastes are produced universally each year.  Hazardous Wastes (Management & Handling) Rules, 1989 notified Under the Environment (Protection) Act 1986 amended in 2000.  The management of hazardous waste in developing countries, with particular emphasis on industrial hazardous waste, medical waste, and household hazardous waste..
 Hazardous wastes make dangerous or potentially harmful to human health or the environment.  Hazardous Waste generally generated with the human activities such as agricultural, industrial, residential, institutional, municipal, commercial, recreational.  These wastes are corrosive, inflammable, explosive, or react when exposed to other materials and also highly toxic .  Hazardous waste management deals with minimizing harmful effects by applying special techniques of handling, storage, transportation, treatment, and disposal of hazardous wastes.
A hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment. Hazardous waste is generated from many sources, ranging from industrial manufacturing process wastes to batteries and may come in many forms, including liquids, solids, gases, and sludges.

Hazardous waste
• To grant, refuse or cancel HW Authorization • To monitor HW generating units for ensuring safe storage, treatment and disposal of wastes • To analyze the waste characteristics in order to decide its nature • To approve the design and layout of a proposed TSDF as per SPCB guidelines
 Production ranges from large industries to individuals.  Chemicals used for industrial processes and the significant rise in use of these chemicals.  Unwillingness of the industries to manage the hazardous wastes due to the heavy expenses involved.
 Transportation requires precise control to ensure safe disposal of such wastes.  To ensure that the generator transport their hazardous waste only in the specified transport vehicles.  The transporters should train the drivers to handle the wastes under emergency situations.
 Hazardous waste containers- containers compatible with the waste and must be in good condition and free of leaks.  Sealing hazardous waste containers- containers must be sealed to prevent leakage and Plastic wrap, other shift lids are unacceptable.  Labeling Hazardous Waste Containers- containers must be labeled including name, telephone number, room number, and exact contents.
 Waste disposal is the final step of waste placing hazardous waste in a dedicated disposal facility.  The disposal of radioactive waste is defined as the emplacement of waste that is intended to isolate the waste from human and environment.  To prevent or limit a release of potentially harmful substances such that human health and the environment are protected.  The effect of climatic conditions, for example, flooding and freezing accidents on the solidified wastes.
 Landfills  Incineration  Recycling
 The disposal of refuse and other waste material by burying it and covering it over with soil
 Incineration is a disposal method solid organic wastes are subjected to combustion .  Convert them into residue and gaseous products.  This process reduces the volumes of solid waste to 20 to 30% of the original volume.
 Recycling is resource recovery practice that refers to the collection and reuse of waste materials.  The materials from which the items are made can be reprocessed into new products.
• Increase in strict regulations on the disposal of hazardous waste. • Industries can break down dangerous chemical compounds into less dangerous forms by physical, chemical, or biological treatment • Participation at individual level. • Provisions of concessions by the government to the industries for treatment and disposal of hazardous wastes.
