o Hazardous Waste: o Any substance that is present in the environment causing substantial damage to public health and welfare of the environment is called hazardous substance. o Any hazardous substance could exhibit any one or more of the following characteristics: toxicity, ignitability, corrosivity or reactivity(explosive). o Hazardous wastes can originate from various sources such as: house hold, local areas, urban, industry, agriculture, construction activity, hospital ls and laboratories, power plants and other sources. o The hazardous waste when disposed of release a number of environmentally unfriendly substance(s). o Hospitals generate hazardous wastes that contain disinfectants and other harmful chemicals, and also pathogenic micro-organisms. Such wastes also require careful treatment and disposal. The use of incinerators (destroy especially waste material, by burning) is crucial to disposal of hospital waste.
SOURCE OF HAZARDOUS WAST 1. Industrial wastes 2. Agricultural waste 3. Household waste 4. Medical waste

PROBLEM OF SOURCE AND COLLECTION Source - Collection Poor disposal at sourceCollection service not Not separate of solid waste and hazardous waste cover all responsible area Lack of containers - Remaining solid waste Improper containers Time consuming (due to solid waste collector spend time for separation)
o Stockholm Convention on Persistent Organic Pollutants o Stockholm Convention is an international environmental treaty came into effective in Aim To eliminate or restrict the production and use of persistent organic pollutants POPs are defined as "chemical substances that persist in the environment, bio-accumulate 2004 (POPs). through the food web, and pose a risk of causing adverse effects to human health and the environment" Important Listed substances Aldrin: Used as a local ectoparasiticide and insecticide Heptachlor: Uses as a termiticide (including in the structure of houses and underground), for organic treatment and in underground cable boxes Hexachlorobenzene: Use as a chemical intermediate and a solvent for pesticides Endrin: Endrin has been used primarily as an agricultural insecticide on tobacco, apple trees, cotton, sugar cane, rice, cereal, and grains. Polychlorinated biphenyl: PCB's commercial utility was based largely on their chemical stability, including low flammability, and physical properties, includ ng electrical insulating properties. They are highly toxic. o o o o o
e Basel Convention: Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal o International treaty that was designed to reduce the movements of hazardous waste between nations o Main goal is to prevent transfer of hazardous waste from developed to less developed countries (LDCs) o It does not address the movement of radioactive waste. o 182 states and the European Union are parties to the Convention e Location -Basel, Switzerland
Rotterdam Convention: Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade Multilateral treaty to promote shared responsibilities in relation to importation of hazardous chemicals. The convention promotes open exchange of information and calls on exporters of hazardous chemicals to use proper labeling, safe handling, and inform purchasers of any known restrictions or bans. o Signatory nations can decide whether to allow or ban the importation of chemicals listed in the treaty..
