As a result of establishing the existing LFG to energy recovery
project, a part of generated CH4 is captured (8.11 kg CH4/tonne of
waste disposed) to produce electricity. In addition, the electricity
produced from recovered LFG is used to replace conventional
electricity production (fossil fuel based) and the associated GHG
emissions can be avoided (GHG emission from Thai grid electricity
production 560 kg CO2-eq/MWh). Thus, the total GHG avoidance
potential from the LFG-to-energy project is 186 kg CO2-eq/tonne of
waste disposed. The net LCC was calculated by subtracting the
above revenues from the gross LCC. As shown in Fig. 2, the net GHG
emissions potential from the existing LFG-to-energy project in BMA
amounts to 1210 kg CO2-eq/tonne of waste disposed, see Fig. 2.
