- Non-Biodegradable wastes.
- Biodegradable wastes: Wastes that rot by the action of decomposers are called biodegradable wastes.
- Non-biodegradable wastes: Wastes that do not rot by the action of decomposers are called non-biodegradable wastes.
- Composting: Converting plant and animal waste including that from kitchen, into manure, is called composting.
- Recycling organic wastes like vegetable peels, waste food, leaves, etc., by burying them in compost pits is called composting.
