Explain different types of waste. |
|
Answer» Waste can be solid, liquid or gas but on the basis of ability to undergo decomposition, waste is classified into two types: Biodegradable Waste: Waste which can be decomposed by biological factors is called biodegradable waste, e.g. fruit peels, stale food, paper, etc. Biodegradable is generally environment-friendly. Biogas is produced on decomposition of biodegradable waste. This biogas can be utilized for many purposes like as domestic fuel, for power generation, etc. Non- biodegradable Waste: Waste which cannot be decomposed by biological factors is called non-biodegradable waste, e.g. aluminium can, polythene bag, etc. Non-biodegradable waste is generally harmful for environment. However, many non-biodegradable waste can be recycled to make useful products. |
