Outline of GHG Mitigation Activity

Cau Dien, an intermediate treatment facility, ferments garbage as part of the municipal solid waste collected in Hanoi City, to create compost. Our new project under consideration introduces a modern methane fermentation system which can treat a mixture of garbage and septage, and we expect it to improve public sanitation in the surrounding areas. Recovered biogas, which can be used at the medical waste treatment facility located in the same premise, replaces fossil fuels and improves energy saving. Digested sludge after fermentation can be made into compost for agriculture.

Expected GHG Emission Reductions

4,323 tCO2/year
Reference CO2 emissions: 4,698 tCO2/year
 Emission by fossil fuel for the medical waste treatment facility (274 tCO2/yr)
 Emission by methane gas generated from landfill (4,424 tCO2/yr) Project CO2 emissions: 375 tCO2/year
 Emission by system power consumption
