Anaerobic Degradation

The biodegradation of organic material in the absence of oxygen catalysed by facultative and obligate microorganisms to produce biogas and digestate as a byproduct is known as anaerobic digestion.

Anaerobic Digester

An enclosed chamber constructed to carry out anaerobic digestion of organic material to produce valuable products like biogas and digestate is known as anaerobic digestor.

Bin Composting

The process of composting organic waste inside a bin with modifications added to accommodate the requirements & to accelerate of a composting process is called bin composting. Bin composting can be performed at household or community level.


The gases produced as a result of anaerobic digestion are known as biogas. Biogas mainly consists of methane, carbon dioxide, hydrogen, H2S, ammonia etc.

Brown Waste

Brown waste is a carbon rich, dry and woody biodegradable material used for composting. Brown waste usually consists of coco-fiber, sawdust, dry leaves, hay, bagasse, paper, dry branches etc. Brown waste must be balanced out with green waste for effective composting.


The accelerated degradation of organic waste by microorganisms in an aerobic environment (in the presence of oxygen / aeration) to produce a nutrionally rich material known as compost.


The slurry emerging from the outlet of a digester post anaerobic degradation rich in nitrogen, phosphorus,potassium and other trace element content is known as digestate.

Green Waste

Green waste is an organic biodegradable waste high in nitrogen and moisture content. Green waste includes manure, grass clippings, kitchen waste. Green waste must be balanced out with brown waste for effective composting.

Municipal solid waste (MSW)

The everyday waste generated at various residential, commercial, industrial and institutional sources that is generally disposed at municipal landfills site is known as municipal solid waste. MSW usually consists of kitchen waste, plastics, metals, papers, cardboards, glass, construction waste, hazardous medical waste etc. The municipal soil waste can be subjected to solid waste management strategies that can reduce the load on landfill site.

Non-organic Waste

Any kind of non biodegradable material such as metal, glass, plastic, radio-active elements etc. are known as non-organic waste.

Organic Waste

Any kind of biodegradable material from plant or animal origin that can be broken down into simpler organic compounds upon degradation is known as organic waste.


Conversion of waste material by segregation and subsequent processing to obtain novel or similar products of heightened value is known as recycling.

Sanitary landfill

A site designed and allocated for disposal, segregation and treatment for biodegradable and non-biodegradable municipal solid waste is known as sanitary landfill.

Solid Waste Management

The process of regulating and managing the generation, collection, disposal, and treatment of discarded solid waste material is known as solid waste management. Read more


The conversion of organic waste materials into nutritionally rich compost using earthworms and microorganisms in a combined natural process is known as vermicomposting.
