Question

difference between non biodegradable and composite waste?

Answer 1

Differences between composite and non-biodegradable wastes:

Composite wastes

1. These wastes can be broken down into non-poisonous substances by the action of microorganisms like bacteria and earthworms.
2. Biodegradable substances change their form and structure over time and become harmless.
3. They do not pollute the environment.
4. Examples: Spoiled food, vegetable peels, tea leaves, wood, grass, paper, leather, cotton, cattle dung etc.

Non-biodegradable wastes

1. These wastes cannot be broken down into harmless substances by any biological processes.
2. Non-biodegradable substances remain unchanged over a long period of time.
3. Some of them remain inert and begin to accumulate in our surroundings, while others cannot be made less toxic easily and hence keep on polluting the environment.
4. Examples: Glass bottles, metal cans, polythene bags, synthetic fibres, radioactive wastes, plastics and pesticides like DDT etc.
