Question

What are the advantages of the biodegradable substances?

Answer 1

Biodegradable substances:

1. Waste materials that can be broken down into simpler, non-toxic substances by microorganisms are called biodegradable substances.
2. Examples: animal waste, waste from vegetables, cattle dung, etc.
3. These wastes undergo degradation due to the action of enzymes or biocatalysts secreted by microbes and enter the biogeochemical cycles.
4. When any biodegradable waste is degraded and mixed with soil it becomes available for the other plants to absorb. This helps maintain ecological balance.
5. Biodegradable waste can be utilized as an excellent source of compost or manure for plants.
6. Cattle dung can be effectively utilized as a source of fuel by producing Gobar gas.
7. Kitchen waste can be used to produce biogas which is a fuel.
