According to India's Solid Waste Management (SWM) Rules, 2016, non-recyclable waste with a calorific value of ______ kcal/kg or higher should be used to generate energy through Waste to Energy (WTE) processes.
- A500
- B1500Correct
- C2500
- D3500
Solution
Concept
SWM Rules 2016 say non-recyclable waste with high calorific value should go to WTE processes.
Step-by-step solution
1. SWM Rules 2016 talk about waste processing and treatment. 2. Non-recyclable waste with calorific value of 1500 kcal/kg or more should go to WTE (RDF, incineration, etc.). 3. Waste with a lower calorific value goes to other processing or to the landfill. 4. Hence the answer is 1500 kcal/kg, which is option B.
Explanation
The rules say non-recyclable waste with calorific value 1500 kcal/kg or more should be used for energy generation. Lower-value waste should not be burnt and should go for other treatment.
Why the other options are wrong
A (500) is too low for energy recovery. C (2500) and D (3500) are higher than the limit given in the rules.
Shortcut
Remember: SWM Rules 2016 = 1500 kcal/kg for WTE.
Common mistake
Mixing this value with the 2500 kcal/kg value used for RDF or the 4000 kcal/kg figure seen in older rules.
Correct answer: B) 1500
