Green dustbin: It is used for disposal of biodegradable waste. Blue dustbin: It is used for disposal of non-biodegradable waste. Green bins contain the waste that is biodegradable, or compostable material that can be converted to manure to divert waste from landfills. ... - The waste generates a lot of organisms around it.

3)

Vermicompost is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.

4) Becoz it not so good to make manure and even it causes smell when it is rotten

5)

Vermicomposting is a process through which the worms convert the organic materials into a humus like material known as vermi-compost. The egg shells are the source of calcium these are added to neutralize the pH of the vermi-composting soil. ... The population of worms will contribute to speed up the composting process

Answer 2

$\huge\mathfrak\pink{hello}$

Here is my 5 answers to your 5 questions

1st question's answer:

➵ There are Two main waste categories can be established based on the distinct legislation and policy instruments usually in place:

1. Non-hazardous or solid waste and
2. hazardous waste.

2nd question's answer:

➵ Significance of Green & Blue Dustbins:

• The Green-coloured dustbins are meant for wet and bioderadable wastes. For eg: kitchen wastes including vegetables and fruits skins.
• Blue dustbins are meant for disposal of plastic wrappers and non-bioderadable wastes.

3rd question's answer:

➵ Vermicomposting is the process by which worms are used to convert organic materials into a humus-like material known as vermin-compost.

4th question's answer:

➵ Reason :

Wastes containing salt, pickle, oil, vinegar, meat and milk products cannot be used as food for the redworms in a vermicomposting pit because these items can lead to the growth of disease-causing small organisms. These small organisms may harm the redworms and hinder the preparation of compost.

5th question's answer:

➵The egg shells are the source of calcium these are added to neutralize the pH of the vermi-composting soil. The egg shells reduces the acidity of the soil as acidity can inhibit the mating and growth of soil worms. Thus helps in maintaining the mating process of worms.
