The purpose of the study is the evaluation of the potential of GHG (green house gas) reductions by installing an anaerobic digester in a wastewater treatment facility in Southeast Asia. In the advanced system, a wastewater is treated in the digester, and methane (biogas) is produced and recovered. Compared with the conventional system, the biogas can be utilized for power generation and substitute fossil fuel. The results show that the largest GHG reduction as the Certified Emission Reduction (CER) credit is 73,000 t-CO_2e/yr, and the reduction cost is 14 USD/t-CO_2e. Although the substitution of the biogas for the fossil fuels reduces only 10% of the GHG emissions, the electricity output can satisfy the electricity consumption.
