Abstract: An accurate estimation of source strength of gas in a landfill is necessary to design gas extraction systems. A one-dimensional mathematical model to estimate source strength of landfill gas is presented. The model is based ...

Abstract: Concern over the potentially negative impacts of climate change has resulted in a search for techniques to reduce anthropogenic emissions of methane, a primary greenhouse gas. Microbial oxidation of methane in soils may ...

Abstract: The long-term operation of a methane biofilter depends on maintaining a favorable environment for methanotrophic bacteria within the porous medium supporting their growth. The concentrations of methane and oxygen, moisture ...

Abstract: Landfill bioreactors have many advantages relative to conventional dry-tomb sanitary landfills. Leachate augmentation with enzymes (prior to its recirculation) to enhance waste degradation and gas production in landfill ...

Abstract: This manuscript presents a detailed discussion of the challenges faced and lessons learned during the initial phase of operation of the Calgary Biocell. The Calgary Biocell is a full-scale pilot project that has been ...
