- 6. Classification of SolidWaste Municipal Solid wastes: Solid wastes that include household garbage, rubbish, construction & packaging materials, etc. and are managed by anymunicipality. Bio-medical wastes: Solid or liquid wastes including containers, products generated during diagnosis, treatment & research activities of medicalsciences. Industrial wastes: Liquid and solid wastes that are generated by manufacturing & processing units of various industries like chemical, petroleum, coal, metal gas, paperetc. Agricultural wastes: Wastes generated from farming activities. These substances are mostlybiodegradable. 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.

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 usin recent years.

- 14. Understand The Various Kinds of MSW Disposal Methods Such asLand Filling, Incineration and Organic MSW Composting.
- 15. • It isthe most traditional method of waste disposal. • Waste isdirectly dumped into quarries, mining voids or borrow pits. • Disposed waste iscompacted and covered with soil. • It isgenerally used for domestic waste. Land Filling

- 18. • Incineration isa 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 ashismostly formed by the inorganic constituents of the waste and gases due to organic waste. • The heat generated by incineration isused to generate electric power. Incineration

- 20. How can we make a change Know 3R’s Concept and Justify Aspects and Issues related to recycling and composting of municipal solid waste (MSW).
- 21. Reduction • By reducing, consumer and industry can save natural resources and reduce waste management costs. Reuse • Large production companies suchas 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.
