Abstract: “Biogas is produced by breaking down organic materials in the absence of oxygen in a process called anaerobic digestion. The organic materials used for production (feedstocks) include: crops specially grown for this purpose, most often maize; food and plants considered waste; sewage sludge; industrial wastewater; as well as animal manure. Gas from landfills can also be collected. Biogas can be used directly for heating and electricity generation.

As biomethane production continues to grow rapidly (with a currently 21% year-over-year growth), so do concerns about its associated environmental and social risks. While biogas production from sludge or collecting the gas that is produced in landfills is appropriate, there are particular concerns about the effects of large-scale biogas production”
