Municipal Solid wastes: Solid wastes that include household garbage, rubbish, construction & packaging materials, etc. and are managed by any municipality.
Bio-medical wastes: Solid or liquid wastes including containers, products generated during diagnosis, treatment & research activities of medical sciences.
Industrial wastes: Liquid and solid wastes that are generated by manufacturing & processing units of various industries like chemical, petroleum, coal, metal gas, paper etc.
Agricultural wastes: Wastes generated from farming activities. These substances are mostly biodegradable.
E-wastes: Electronic wastes generated from any modern establishments. They may be described as discarded electrical or electronic devices. Some electronic scrap components, such as wires, circuits, mobile, computers etc.

Muncipal solid waste generation
in india

7.2 million tonnes of hazardous waste. One Sq. km of additional landfill area is needed every-year. Rs 1600 crore for treatment & disposal of these wastes. In addition to this industries discharge about 150 million
tonnes of high volume low hazard waste every year, which is mostly dumped on open low lying land areas.
Solid Waste in India

In Mumbai (2005) the sewage line is cloged due to large no. of plastic bags.
Blast in the Bhusan Steel factory at Noida, caused due to imported scrap from Iran.
Reduction in the number of migratory birds due to consumption of contaminated foods.
Animals dying on streets due to consumption of plastic bags, which blocks the food movement in their stomach .
How solid waste affected us in recent years?

Waste management is the storage collection transport and handling recycling disposal and monitoring of
waste materials.

Waste handling and separation involves activities associated with waste management until the waste is placed in storage containers for collection. Handling also encompasses the movement of loaded containers to the point of collection.
waste is transferred from a smaller collection vehicle to larger transport equipment
Waste handling and
transport

Method of disposal
![Page 19: solid waste management by abrar saleem](https://reader035.vdocuments.net/reader035/viewer/2022062503/588602b01a28ab0a3f8b5d05/html5/thumbnails/19.jpg)
It is the most traditional method of waste disposal. Waste is directly dumped into quarries, mining
voids or borrow pits. Disposed waste is compacted and covered with
soil. It is generally used for domestic waste.
Land Filling

Incineration is a waste treatment process that involves the combustion of solid waste at 1000^o C.
waste materials are converted into ash, flue gas, and heat.
The ash is mostly formed by the inorganic constituents of the waste and gases due to organic waste.
The heat generated by incineration is used to generate electric power.

Know 3R’s Concept and Justify Aspects and Issues related to recycling and composting of municipal
solid waste (MSW).
How can we make a change
![Page 24: solid waste management by abrar saleem](https://reader035.vdocuments.net/reader035/viewer/2022062503/588602b01a28ab0a3f8b5d05/html5/thumbnails/24.jpg)
Reduction• By reducing, consumer and industry can save natural
resources and reduce waste management costs.
Reuse• Large production companies such as Electronic,
appliances and gadgets, should establish the collection centre, where damaged items can be repaired and reuse.
Recycling• Recycling turns materials that would otherwise become
waste into valuable resources.
![Page 25: solid waste management by abrar saleem](https://reader035.vdocuments.net/reader035/viewer/2022062503/588602b01a28ab0a3f8b5d05/html5/thumbnails/25.jpg)
Waste generation and waste reduction reflect many complex economic and social factors. No city or town can adopt recommendations in a vacuum; each must examine its own wastes, and the potential for extending waste reduction.
