Question

What do you mean by Non-biodegradable waste. Give some examples.

Answer 1

Non-biodegradable waste:
Those materials which cannot be broken down or decomposed into the soil by micro-organisms and natural agents are labeled as non-biodegradable.

• These substances consist of plastic materials, metal scraps, aluminum cans and bottles, etc.
• These things are practically immune to the natural processes and thus cannot be fed upon or broken down even after thousands of years.
