title: Function and limits of biofilters for the removal of methane in exhaust gases from the pig industry.
abstract: The agricultural sector is responsible for an important part of Canadian greenhouse gas (GHG) emissions, 8 % of the 747 Mt eq. CO(2) emitted each year. The pork industry, a key sector of the agrifood industry, has had a rapid growth in Canada since the middle 1980s. For this industry, slurry storage accounts for the major part of methane (CH(4)) emissions, a GHG 25 times higher than carbon dioxide (CO(2)) on a 100-year time horizon. Intending to reduce these emissions, biofiltration, a process effective to treat CH(4) from landfills and coal mines, could be effective to treat CH(4) from the pig industry. Biofiltration is a complex process that requires the understanding of the biological process of CH(4) oxidation and a control of the engineering parameters (filter bed, temperature, etc.). Some biofiltration studies show that this technology could be used to treat CH(4) at a relatively low cost and with a relatively high purification performance.
