Patrick Serfass of the American Biogas Council joins the Catching Carbon Podcast to discuss the evolution of biogas as a viable source of CO2, and the importance of that CO2 being biogenic in nature. The group walks through the process of biogas upgrading, importance of the renewable natural gas, and the possible outlets for the byproduct CO2 that has historically been turned to waste. Additionally, the episode addresses concerns around the viability of the source, and methods to overcome.
