Enhancement of Landfill Gas Production and Waste Stabilization by Using Geotextile Filter in a Bioreactor Landfill

Optimising the methane production period is a better way to control the greenhouse gas impact of landfill gas (LFG). This study aims to enhance biodegradation and methane production. Two bioreactors are used to evaluate the rate of LFG production and waste stabilisation. The simulated bioreactor is equipped with a geotextile filter (LBR-GT) and showed a better performance than the control bioreactor (LBR-C). A total of 1194 L and 1128 L of LFG were produced from the LBR-GT and the LBR-C respectively. This study showed that the LFG production is enhanced since the LBR-GT produced 85% of its total LFG in only 1 month whereas the LBR-C produced 85% of its total LFG in more than 3 months. The study suggests there is a benefit of using geotextiles to enhance the operation of a landfill as a bioreactor and to control the greenhouse gas impact of LFG.
