TL;DR: The data document the ability of the bioreactor operation to enhance landfill CH4 generation, although the estimated decay rate is sensitive to the selected L0, and emphasizes the importance of having a LFG collection system operational once the waste receives added moisture.
Abstract: Prediction of the rate of gas production from bioreactor landfills is important for the optimization of energy recovery and for estimating greenhouse gas emissions. To improve the predictability of gas production, landfill gas (LFG) composition and flow rates were monitored for 4 yr from one conventional and two bioreactor landfill cells at the Outer Loop Landfill in Louisville, KY. The ultimate methane yield (L 0) was estimated from the biochemical methane (CH4) potential of freshly buried refuse and the decay rate constant (k) was estimated from measured CH4 collection. The site-specific L 0 was estimated to be 48.4 m3-CH4 wet Mg−1. The estimated decay rate in the conventional cell (0.06 yr−1) was comparable to the AP-42 default value of 0.04 yr−1, whereas estimates for the two bioreactor cells were substantially higher (˜0.11 yr−1). The data document the ability of the bioreactor operation to enhance landfill CH4 generation, although the estimated decay rate is sensitive to the selected L0. Th...
