Why are biodegradable wastes preferred over non-biodegradable wastes?

Biodegradable wastes are preferred because they break down naturally and do not harm the environment, while non biodegradable wastes accumulate and cause pollution.

Key Comparison

Factor	Biodegradable Waste	Non Biodegradable Waste
Decomposition	Breaks down naturally	Does not decompose easily
Environmental Impact	Eco friendly	Causes pollution
Microbial Action	Can be decomposed by microbes	Cannot be decomposed by microbes
Soil Fertility	Improves soil	No benefit to soil
Accumulation	Does not accumulate	Accumulates over time

Stepwise Explanation

1. Biodegradable waste like food, leaves gets decomposed by microbes

2. It converts into nutrients and humus

3. This improves soil and supports plant growth

4. Non biodegradable waste like plastic remains in environment

5. It keeps accumulating and creates long term problems

Important Concept

Sustainable waste management depends on using materials that can return to nature safely.

Real Insight

Using kitchen waste for compost is a good example, while plastic waste keeps increasing and creates disposal issues.

Conclusion

Biodegradable wastes are preferred because they decompose naturally, reduce pollution, and support ecological balance, unlike non biodegradable wastes which persist and harm the environment.
