Biodegradable and Non-biodegradable material

A material which gets decomposed through natural processes (such as action of bacteria)are called as biodegradable material.

For Ex:Plant waste,animal waste,paper,cotton,cloth,woollen cloth,jute,wood are all biodegradable material.

They rot away with time and hence do not cause pollution in the environment.

A material which does not get decomposed through natural processes (such as action of bacteria)are called as non- biodegradable material.

For Ex:Plastics,glass,metals,aluminium cans etc.

They do not rot away with time and hence cause pollution in the environment.
