Kyla and Kristen are joined by Peter Harris, post-doctoral research fellow for the Centre for Agricultural Engineering in Australia, working on the bioenergy and bio-resource recovery team. He works on projects involving a process called anaerobic digestion, which can be used to turn biowaste into energy, while recovering useful elements. Pete discusses: the history of anaerobic digestion, what is biogas, can cow-farts be turned into energy, the potential for biogas as a sustainable energy source, barriers to biogas adoption, and how can we best utilize this technology?
