GREEN HOUSE GAS EMISSION REDUCTION IN MANURE MANAGEMENT AND BIOGAS SLURY TREATMENT

Abstract

Application of AMS IIID (methane recovery in the manure management systems),

AMS.IIIH (methane recovery in the wastewater treatment) and AMS.IC (use biogas instead of electricity and fossil fuel) by International Panel of Climate Change, combined with analysis data, we calculated baseline emission, project emission and methane emission reduction in pig manure treatment for one household of 45 pigs and for Yen Lac district with 58806pigs. According to the survey in Yen Lac district, Yen L_c district discharge 104.8 ton of pig manure

per day or 6288m3CH4/day in 2009. Changing manure management method, manure treated in the biogas that contributes to reduce 0.315tCO2e/pig/year. And then, carbon emission reduction is from 0.082 to 0.089tCO2e within biogas recovery and intensive anaerobic treatment. Alternative use of recovery biogas from the biogas and UASB contributes to reduce 0.072tCO2e/pig/year. Total of methane emission reduction for the whole advanced biogas model is from 0.469 to 0.476tCO2e/pig/year. It shows that, slurry treatment stage from advanced biogas

model can reduce significantly green house gas of 5233.7tCO2e per district, and the advanced model is more effective than the tranditional one. Especially, methane emission reduction potential for Yen lac district is 27991tCO2e which is the big potential for clean development mechanism projects
