The calorific value of municipal solid waste (MSW) determines the feasibility of:
Environmental EngineeringSolid Waste Calorific ValueMEDIUM
Choose the correct answer
A
Composting
B
Landfill disposal
C
Waste-to-Energy (WTE) incineration
D
Open burning
Correct Answer
C. Waste-to-Energy (WTE) incineration
Why is this the answer?
WTE feasibility requires minimum calorific value of ~1200-1500 kcal/kg (Indian MSW is ~800-1200 kcal/kg due to high moisture and organics). Indian MSW: moisture 40-60%, organics 40-60%, inerts 20-40%. Higher income cities have higher CV. Composting works for high-organic MSW.
