Biodegradable waste is waste that can break down by biological processes into natural components and be recycled naturally by the action of bacteria or other saprophytes. Examples are old vegetables / food, paper, cardboard, deceased animals, and Phyto plastics (special plastics that break down when exposed to the sun after some time) etc.
Non-Biodegradable waste is waste that does not break down into natural components and exists in the environment for a long time or may harm the various members of the eco- system.. Examples would be tyres, plastics, electronic components, metals etc.
