Overview
The China: Tianjin Landfill Gas Recovery and Utilization project consisted of the construction of a landfill gas (LFG) utilization system to generate electricity for landfill operations and to feed to the power grid of Tianjin City. The generators combusted the methane in the LFG to produce electricity for sale to the North China Power Grid. Excess LFG, as well as all gas collected during periods when electricity is not generated, were flared. The project used methodology ACM0001 – version 5 – Consolidated baseline and monitoring methodology for landfill gas activities. The project activities involved the reconstruction of the landfill and the set-up of LFG recovery systems in its working cells, including such systems as LFG collection, pre-treatment, electricity generation and grid connection, flaring, monitoring and protection system, data recording and archiving. This project reduced greenhouse gas emissions generated from the landfill, including power generation offsets. During the project design, it was expected that the project would reduce greenhouse gas emissions by a total of approximately 1,558,228 tonnes of carbon dioxide equivalents (tCO2e) during the 10-year crediting period, from 2008 to 2017 and produce a total of 218,509 MWh electricity during this period of time, 95% of which was sent to the grid while the remaining 5% was used on-site ex ante.
