Policies and preventive measures
Minimization of GHGs
Environmental and Socio-economic benefit
Efficient waste segregation
CO
2 , CH
4 , and N
2 O
• Regulation economic incentive
• Reduce the burden on waste management system and
landfill sites
Reduction in biodegradable waste which is landfilled
CO
2 , CH
4 , and N
2 O
• Prevent microbial decomposition of organic matter and
subsequent emission of CH
4 and N
2 O
• Regulation economic incentive
• Reduces foul smell
Aerobic biological treatment of wastes
CO
2
• Although reduces CO
2 emissions but can emit N
2 O and
CH
4 under reduced aeration or anaerobic conditions
• Reduces volume, stabilizes organic C, and destroys
pathogens
• Compost generation which can be used as fertilizer
• Job creation
• Foul odor reduction
Anaerobic biological treatment of wastes with energy
recovery system
CH
4 and N
2 O
• Even though minimizes CO
2 generation but if not
properly managed, leads to enormous CH
4 emission
• CH
4 in biogas can be used as fuels for
• heat or electricity generation
• Produce biosolid under controlled conditions
• Job creation
• Foul odor reduction
• Job creation
