Electricity generation and greenhouse gas (GHG) reductions were researched by making comparisons between municipal solid waste (MSW) landfill and incineration systems with three different electricity generation efficiencies - 10%, 21%, and 24.7%. For MSW landfill systems, it is shown that the total electricity generation is 198,747 MWh, and the total GHG emission reduction is 1,386,081 tonne CO( 2) during a 21-year operation period. For incineration systems, the total electricity generation is 611,801 MWh, and the total GHG emission reduction is 1,339,158 tonne CO(2) during a 10-year operation period even if the electricity generation efficiency is only 10%. It is also shown that electricity generation increases quicker than the GHG emission reductions with the increase of electricity generation efficiency. However, incineration systems show great superiority in LFG utilisation and GHG emission reductions.
对三种不同发电效率（10%、21%和 24.7%）的城市固体废物（MSW）填埋场和焚烧系统进行了比较，研究了发电和温室气体（GHG）减排情况。对于 MSW 填埋场系统，在 21 年的运行期间，总发电量为 198747 兆瓦时，总 GHG 减排量为 1386081 吨 CO2。对于焚烧系统，即使发电效率仅为 10%，在 10 年的运行期间，总发电量为 611801 兆瓦时，总 GHG 减排量为 1339158 吨 CO2。研究结果还表明，随着发电效率的提高，发电量的增长速度快于 GHG 减排量的增长速度。然而，焚烧系统在沼气利用和 GHG 减排方面具有很大的优势。
