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.
Below is a simple school/College activity to know about Biodegradable and Non-biodegradable things.
Materials Required: Two pots, Little amount of Soil, Plastic pieces, Polythene, aluminium foils, Canes, Plants and Waste Papers
- Take two pots and label them as Biodegradable and Non-biodegradable.
- Fill both pots to the half with soil.
- Now, keep the Plastic, Polythene and aluminium foils in non Biodegradable pot.
- Keep Plant and Waste Papers in Biodegradable pot.
- Record changes occur in these pots at least for one week.
- Take images showing the top view of both pots and observe.
- You will not see any changes in the Non- biodegradable pot.
- Bio degradable substances break down naturally.
