Biogas is a combustible gaseous fuel that is collected from the microbial degradation of organic matter in anaerobic conditions. Biogas is principally a mixture of methane (CH4) and carbon dioxide (CO2) along with other trace gases. Biogas can be collected from landfills, covered manure pits on dairy farms, or enclosed tanks called anaerobic digesters.
Biogas is commonly made from animal manure, sludge settled from wastewater, and at landfills containing organic wastes. However, biogas can also be made from almost any feedstock containing organic compounds, both wastes, and biomass (energy crops). Carbohydrates, proteins, and lipids are all readily converted to biogas. Many wastewaters contain organic compounds that may be converted to biogas including municipal wastewater, food processing wastewater, and many industrial wastewaters. Solid and semi-solid materials that include plant or animal matter can be converted to biogas.
Biogas use has advanced tremendously over the last 10 years. Biogas can be used to generate electricity, sell back to the utility company, use on your operations as a natural gas substitute, or purchased by companies needing to comply with LCFS (low carbon fuel standard). The uses will vary by region and utility company, but worth looking into to find out if you are sitting on an untapped resource.
