Solid Waste Management
What Is Waste..?
Waste (also known as rubbish, trash, refuse, garbage, or junk) is unwanted or unusable materials.
According to United Nations Statistics Division(UNSD) it is defined as
"Wastes are materials that are not prime products (that is products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose. Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded."
Types:
Municipal Solid Waste(MSW)
Construction Waste
Industrial Waste
Medical Waste
Hazardous Waste (Radioactive , Electronic)
Industrial waste
Key Aspects Of Waste Management
Waste disposal
Waste processing
Waste recycling
Waste minimization
Waste disposal
Land filling
Composting
Incineration
Anaerobic digestion
Mechanical biological treatment
Preventing ground water pollution in a landfill
An adequate lining system is a necessary component for any landfill. The liner is designed as a barrier to intercept leachate and direct it to a collection system to prevent contamination of local groundwater.
Concerns over Incineration
Incineration recovers energy that would otherwise be lost
Requires less land
Reduces odor but…
Emits dangerous cancer causing compounds called dioxins
