1 Environmental Chemistry Industrial WasteLearning ObjectivesWastes and its classification.Biodegradable and non-biodegradable wastes.Hazardous and non- hazardous wastes.Effects of wastes.Waste management.
2 Environmental Chemistry Industrial WasteWastesWastes 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.
3 Environmental Chemistry Industrial WasteIndustrial wastesIndustrial 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.
4 Environmental Chemistry Industrial WasteClassification of Industrial Wastes according to their PropertiesIndustrial WastesBiodegradable WastesNon-biodegradable Wastes
5 Environmental Chemistry Industrial WasteBiodegradable wastesBiodegradable 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, andtextile factories.
6 Environmental Chemistry Industrial WasteNon-biodegradable wastesNon-biodegradable waste is waste that cannot be broken down naturally either by air, climate, moisture or soil.Non-biodegradable wastes are generatedby thermal power plants which produce fly ash; integrated iron and steel plants which produce blast furnace slag and steel melting slag.
7 Environmental Chemistry Industrial WasteClassification of Wastes according to their Effects on Human Health and the EnvironmentHazardous wastesSubstances 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 wastesSubstances 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.
8 Environmental Chemistry Industrial WasteEffects of WastesAffects our health.Affects our socio-economic conditions.Affects our coastal and marine environment.Affects our climate.
9 Environmental Chemistry Industrial WasteWaste ManagementThe 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.
10 Environmental Chemistry Industrial WasteWaste ManagementCollection and DisposalDomestic 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.
11 Environmental Chemistry Industrial WasteWaste ManagementCollection and DisposalAt the site, garbage is sorted out and separated intobiodegradable and non-biodegradable materials.
12 Environmental Chemistry Industrial WasteWaste ManagementCollection and DisposalNon-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.
13 Environmental Chemistry Industrial WasteWaste ManagementEducation 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.
