What is non-biodegradable waste? (the waste when disposed in garbage

pile, cannot be broken down into simpler substances by the

air, moisture,climate, soil or living things is called as non-biodegradable waste)

waste go and what happens to it?the waste is collected from different homes, the first step in the waste management is to separate the solid waste from the liquidwaste. In the next step, solid waste is again divided into biodegradable and nonbiodegradable waste.

Ø How do we can separate biodegradable and non-biodegradable waste?if the waste is separated as biodegradable and nonbiodegradable at the source then it can make the waste treatment process faster, cheaper and more effective.every household/school/colleges/public places should have one bin

for biodegradable waste and another one for non biodegradable waste.

Ø What are decomposers? (microorganisms such as bacteria and fungi are called decomposers)

Ø Give examples of decomposers used for composting. (earthworm, fungi and microorganisms)

Ø How do the Earthworms help to convert waste into the compost?

Is it necessary to separate biodegradable and non-biodegradable waste .YES

Ø How can the process of composting enhance? (by creating and controlling the conditions required for composting)

Ø What did the decomposer require for decomposing? (dead matter of living organisms)

Ø What is vermicomposting? (earthworms are used for the process of composting and the process is called vermicomposting)

Ø What is the use of biogas? (it is used as a fuel)

released directly into open water bodies in India liquid waste (household)

grey water (water coming out from kitchen sinks, showers and washing machineblack water

(water coming out from toilets and urinals

ØCan we dispose the non-biodegradable waste in the same way as biodegradable waste? (no)

ØDo you think non-biodegradable waste can be decomposed bymicroorganisms? (no)

ØYou must have seen your mother giving old papers, glass bottles and metal cans to scrap dealer. What did the scrap dealer do with these items?

·reduce, reuse and recycle works best for non-biodegradable waste and metal, glass and plastic are most commonly recycled non-biodegradable waste.
