Solution

Biodegradable waste

Non-biodegradable waste

(i)

Biodegradable waste can be degraded or broken down into simpler, harmless substances by living organisms like microbes or microorganism

Non-biodegradable waste cannot be degraded or broken down into simpler substances by living organisms.

(ii)

The degradation process in Biodegradable waste is fast

The degradation process in Non-Biodegradable waste is slower than in biodegradable

(iii)

Biodegradable waste is not collected but is used up in a short time

Non-Biodegradable waste often collected

(iv)

Breakdown of these wastes enriches the soil such as plant and animal wastes. Therefore, such wastes are beneficial for the soil.

They do not break down and cause soil pollution. For e.g. plastics, glass, etc. Such wastes are harmful to the soil.

 

(vi)

Biodegradable waste has become part of biogeochemical cycles and give back quick turnover

Most of Non-Biodegradable waste can never enter biogeochemical cycles, very slow and more harmful for earth
