Environmental Chemistry Industrial Waste Learning Objectives Wastes and its classification. Biodegradable and non-biodegradable wastes. Hazardous and non- hazardous wastes. Effects of wastes. Waste management.

Environmental Chemistry Industrial Waste Wastes Wastes are the substances or objects which are disposed of or are intended to be disposed of or are required to be disposed of by the provisions of the law.

Environmental Chemistry Industrial Waste Industrial wastes Industrial waste is the waste produced by industrial activity, such as that of factories, mills and mines. It has existed since the outset of the industrial revolution.

Environmental Chemistry Industrial Waste Classification of Industrial Wastes according to their Properties Industrial Wastes Biodegradable Wastes Non-biodegradable Wastes

Environmental Chemistry Industrial Waste Biodegradable wastes Biodegradable waste is animal or plant matter that breaks down naturally with exposure to microorganisms, heat and oxygen. Biodegradable wastes are generated by cotton mills, food processing units, paper mills, and textile factories.

Environmental Chemistry Industrial Waste Non-biodegradable wastes Non-biodegradable waste is waste that cannot be broken down naturally either by air, climate, moisture or soil. Non-biodegradable wastes are generated by thermal power plants which produce fly ash; integrated iron and steel plants which produce blast furnace slag and steel melting slag.

Environmental Chemistry Industrial Waste Classification of Wastes according to their Effects on Human Health and the Environment Hazardous wastes Substances unsafe to use commercially, industrially, agriculturally, or economically that are shipped, transported to or brought from the country of origin for dumping or disposal in, or in transit through, any part of the territory. Non-hazardous wastes Substances safe to use commercially, industrially, agriculturally, or economically that are shipped, transported to or brought from the country of origin for dumping or disposal in, or in transit through, any part of the territory.

Environmental Chemistry Industrial Waste Effects of Wastes Affects our health. Affects our socio-economic conditions. Affects our coastal and marine environment. Affects our climate.

Environmental Chemistry Industrial Waste Waste Management The improper disposal of wastes is one of the major causes of environmental degradation. Therefore, the management of wastes is of utmost importance. Waste management means the collection, transport, processing or disposal, managing and monitoring of waste materials to minimize its' consequences on humans and environment.

Environmental Chemistry Industrial Waste Waste Management Collection and Disposal Domestic wastes are collected in small bins, which are then transferred to community bins by private or municipal workers. From these community bins, these are collected and carried to the disposable site.

Environmental Chemistry Industrial Waste Waste Management Collection and Disposal At the site, garbage is sorted out and separated into biodegradable and non-biodegradable materials.

Environmental Chemistry Industrial Waste Waste Management Collection and Disposal Non-biodegradable materials such as plastic, glass, metal scraps etc. are sent for recycling. Biodegradable wastes are deposited in land fills and are converted into compost.

Environmental Chemistry Industrial Waste Waste Management Education campaign on waste management needs to be organised that includes an extensive internal web site, quarterly newsletters, daily bulletins, promotional signs and helpful reference labels within the campus of an institution.
