Free thinker Why biogas? With rising energy costs, growing climate change concerns, and such similar problems, as one kind of renewable energy (green energy), biogas is rapidly reclaiming its rightful place in our energy portfolio. Unlike fossil fuel combustion, biogas production from biomass is considered CO 2 neutral. Biogas therefore does not emit additional Greenhouse Gases (GHG) into the atmosphere. However, if biogas is not recovered properly, it will contribute to a GHG effect 20 times worst than if methane is simply combusted! This really needs our focus! Therefore, there is a real incentive to transfer biogas combustion energy (power) into heat and/or electricity. Finally, biogas production from anaerobic digester presents the additional advantage of treating organic waste and reducing the environmental impact of these wastes. Biogas production contributes to a better image of the farming community while reducing odor, pathogens and weeds from the manure and producing an enhance fertilizer easily assimilated by plants.
