Solution
Concept
Rubbish is the non-putrescible part of solid waste (paper, wood, cloth, glass, metal, tins). It does not rot quickly.
Step-by-step solution
1. Refuse is classified as garbage, rubbish and ashes. 2. Garbage is putrescible waste (kitchen and food waste) that decays fast. 3. Rubbish is non-putrescible waste. It can be combustible (paper, wood, cloth) or non-combustible (glass, metal, crockery). 4. So rubbish is non-putrescible solid waste. Answer is (B).
Explanation
Rubbish is dry solid waste like paper, rags, glass and tins that does not decay quickly. Garbage is the wet, decaying food waste. So rubbish is non-putrescible.
Why the other options are wrong
A: nuclear waste is a separate category of hazardous waste. C: putrescible waste is garbage, not rubbish. D: biodegradable waste mainly means garbage or food waste.
Shortcut
Garbage = rots (putrescible). Rubbish = does not rot (non-putrescible).
Common mistake
Confusing rubbish with garbage because both words mean 'waste' in daily use.
Correct answer: B) non-putrescible solid waste
