2. What are Wastes? Waste are unwanted or unusable residual material or any substance which is discarded after primary use . According to the, Basel convention definition of wastes “ 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. Kinds of Wastes Solid wastes:- wastes in solid forms, domestic, commercial and industrial wastes Examples:- Paper, Plastic, Scrap iron, and other trace. Liquid Wastes:- Waste in liquid form Example:- domestic washings, chemicals, oils, manufacturing industries and other sources.

4. According to EPA/USEPA regulations, SOLID WASTE is Any garbage or refuse Other discarded material Sludge from a wastewater treatment plant, water supply treatment plant Solid, liquid, semi-solid, or contained gaseous material from industrial, commercial, mining, and agricultural operations, and from community activities http:// www.epa.gov/epaoswer/osw/basifact.htm#solidwaste

5. Classification of Wastes according to their Properties Bio-degradable Can be disintegration of materials by bacteria, fungi, or other biological means (paper, wood, fruits and others. Generally Organic Material) Non-biodegradable Can not be disintegrated easily (plastics, bottles, old machines, Cans, Glass etc)

6. Wastes Classification according to their Effects on Human Health and the Environment Hazardous wastes:- Hazardous waste is a waste with properties that make it potentially dangerous or harmful to human health or the environment. They can be liquids, solids, or contained gases. A nd have any of the following properties- ignitability, corrosivity , reactivity & toxicity. Non-hazardous waste:- Substance safe to use commercially, industrially, or economically and do not have any of those properties mentioned above.

7. Classification of Wastes according to their Origin and Type Industrial waste:- It is the waste produced by industrial activity which includes any material that is useless during a manufacturing process such as that of factories, industries, mills, and mining operations . Municipal Solid wastes:- Solid waste that include Household waste, Commercial waste, and Demolished waste. Bio-Medical waste:- Solid and liquid waste that include all clinical waste. (such as syringes, cotton tablets refer, needles and gauge pieces) Special hazardous waste:- Included Radioactive waste, Explosive waste, and Electronics waste. Agricultural wastes:- Wastes generated from farming activities. These substances are mostly biodegradable

8. Sources of Wastes Households Commerce and Industry

9. Solid Waste in India India produces more than 42.0 million tons of municipal solid waste annually. Per capita waste generation increasing by 1.3% per annum Yearly increase in waste generation is around 5% annually

10. IMPACTS OF WASTE IF NOT MANAGED PROPERLY Affects our climate Affects our coastal and marine environment Affects our health Affects our socio-economic conditions

11. WASTE DISPOSAL [All activity and actions required to manage waste from, its Inception to Final disposal] Waste hierarchy :- Waste hierarchy refers to 3 Rs Reduce, Reuse, Recycle.

12. DISPOSAL SOLUTION Landfill Incineration ( 1 ) Landfill :- Landfill, is a site for disposal of waste material by burial and is the oldest form of waste management treatment .

13. (2) Incineration :- Incineration is a waste treatment process that involves the combustion of organic substance in waste material. Incineration of waste material are convert the waste into ash, flue gas and heat. Incineration and other high Temp. waste treatment system are described as “Thermal Treatment”.

14. Other Method Of Solid Waste Disposal A nd Management Open Burning Dumping into the sea Composting Ploughing in field Hog feedind Grinding and Discharging into sewers Salvaging Fermentation and Biological dig

15. WHAT SHOULD BE DONE Reduce Waste :- Reduce waste by implementing a formal policies as waste minimization. Include Redesigning product, Changing society patterns, Concerning Consumption & Production of waste generation, and To prevent the creation of waste .

16. WHAT SHOULD BE DONE Re-used :- Reused is the action or practice of using something again. It help to save Energy, Resources, Money and Time.

17. WHAT SHOULD BE DONE Re-Cycling :- Recycling is the process of converting waste material into new material and objects. Material for Recycling may be collected separately or doing separate, From general waste using dedicate bins and collection vehicles.

18. WHAT SHOULD BE DONE Employee Education :- Train employees on recycling practices prior to implementing recycling programs. Develop an “recycling procedures” packet.
