Biodegradable wastes are less harmful pollutants to us than non-biodegradable wastes. Which of the following groups contains only biodegradable wastes?

Biodegradable wastes are less harmful pollutants to us than non-biodegradable wastes. Which of the following groups contains only biodegradable wastes? Correct Answer Wood, spoilt food, and vegetable peels

Concept:

Biodegradable wastes:

• The wastes that can be degraded or decomposed in nature by the action of different microbes and other living things using processes like composting, aerobic digestion, anaerobic digestion, etc are called Biodegradable wastes.
• Examples include wood, fruits, vegetables, dead animal and plants, etc.
• These wastes majorly include organic matter which can be broken down into simpler organic molecules like carbon dioxide, methane, water.
• However, some Inorganic matters are also included which can be degraded by microbial action like gypsum.

​Non-biodegradable wastes:

• The wastes that cannot be degraded or decomposed in nature by the action of different microbes and other living things using processes like composting, aerobic digestion, anaerobic digestion, etc are called Non-Biodegradable wastes.
• These wastes act as a source of environmental pollution.
• Examples include plastic, glass, metallic wastes, etc.​

​​​​​​

​Explanation:

• Wood, spoilt food, and vegetable peels all come under the category of organic matter which can be easily degraded by microbial action.
• These things act as natural manure after decomposition and can be used to increase soil fertility.

Additional Information

•  Bubble wraps, PVC pipes, Bakelite switches, Empty milk sachets, Plastic cans, and DDT all are Non-biodegradable wastes as they are not decomposed in nature.
