The influence of moisture enhancement on landfill gas generation in a full-scale landfill.

The objective of this study was to investigate the influence of different moisture enhancement strategies on landfill gas generation in a full-scale solid waste landfill. Moisture enhancement strategies included leachate recirculation and liquid waste addition that were implemented to promote in situ waste decomposition. Waste mass disposed at the landfill and measured gas flow rates in the gas collection system were partitioned among four phases of the landfill that were operated with different moisture enhancement strategies.
