Biodegradable Substances

A biodegradable material can be defined as a material which can be decomposed by bacteria or other natural organisms and not be added to pollution.

Biodegradable wastes are such waste materials which are and can be degraded by natural factors like microbes (e.g. bacteria, fungi and a few more), and abiotic elements like temperature, UV, oxygen, etc. Some examples of such wastes are food materials, kitchen wastes and other natural wastes.

Non-biodegradable Substances

A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution.

Unlike biodegradable wastes, non-biodegradable cannot be easily handled. Non-biodegradable wastes are those that cannot be decomposed or dissolved by natural agents. They remain on earth for thousands of years without any degradation. Since non-biodegradable wastes are not Eco-friendly, they need to be replaced.

Amongst the following options, Aluminium wire and synthetic fibre are the non-biodegradable substances.
