In order to understand the effectiveness of such LFG-to-energy
recovery projects on GHG mitigation, the net impact of the project
waste was compared with the net impact of sanitary landfill
without gas recovery, which is the BAU practice in most of Thai
cities. If the waste generated in BMA is disposed of in a sanitary
landfill (without gas recovery), life cycle GHG emissions would be
equal to 1396 kg of CO2-eq/tonne of waste. According to these results,
the current LFG-to-energy recovery project at Rachathewa
landfill resulted in only 13% GHG reduction compared to the BAU
practice, see Fig. 2.
