Comparision of two different ways of landfill gas utilization through greenhouse gas emission reductions analysis and financial analysis.
Greenhouse gas (GHG) emission reductions and utilization of landfill gas (LFG) were researched by comparing LFG displacing the use of natural gas (scenario 2) with electricity generation using LFG (scenario 3) at three different LFG collecting efficiencies; 35, 50 and 65%. The results show that the utilization of LFG in scenario 2 is 1.4 times that in scenario 3. GHG emission reductions generated by scenario 2 are slightly less than that of scenario 3. The GHG emission reductions and utilization of LFG are restricted by LFG collecting efficiencies. It will be helpful to improve the management level of landfill and the GHG emissions reduction by introducing the CDM. However, the utilization of LFG will be still short of financial attractiveness if the LFG collection efficiency is less than 50%.
