China has environmental regulations in place to deal with the management of landfills and to encourage utilization of landfill gas (LFG). However, due to a lack of environmental technology know-how, in China the municipal refuse is mainly still disposed using the technology of traditional landfill, without consideration of recovery and utilization of landfill methane.
It is estimated that the annual quantity of municipal refuse filled is about 50 million tons. As nearly all landfills – except several recently built new landfills – are not equipped with landfill gas recovery mechanisms, enormous amounts of landfill methane are emitted into the atmosphere.
The Jiyuan MSW Landfill Site LFG Recovery to Power Project aims to recover and destroy landfill gas generated at the municipal solid waste (MSW) landfill site located in Jiyuan city, Henan province (China). The collected LFG will be used for electricity production.
The Jiyuan city landfill site started operation in 2004 and has a capacity of 1.6 million tons of solid waste. It is expected to run for a total of 14 years, till 2018. Degassing pipes have been installed on the landfill site for safety reasons only and since no LFG collection and/or destruction facilities existed prior to the project activity, the baseline scenario without the project envisaged the release of LFG directly into the atmosphere.
The project will employ a gas collection, transmitting and pre-treatment system as well as gas engines with a capacity of 1.5 MW. The recovered LFG will be combusted in the gas engines to produce electricity which will be fed into the Central China Power Grid (CCPG) afterwards. GHG emission reductions will be claimed from both methane recovery and the replacement of electricity mainly generated by the utilization of fossil fuels.
It is estimated that in the 10 years crediting period the project with 1.5MW engine capacity would destroy 11,460 tons of methane and replace and replace 83,516 MWh of electricity otherwise generated via fossil fuel combustion, thus 306,000 tCO2e emissions could be reduced.
