A professor from the Cape Peninsula University of Technology has identified household and agricultural waste in South Africa as a valuable source of clean energy that can be deployed in communities, complexes and individual homes at a lower cost and with a faster return on investment than solar power.

Professor Vincent Okudoh, associate professor for biotechnology at the university’s Department of Biotechnology and Consumer Sciences, says more people globally are recognising biogas as a safe, affordable and environment-friendly source of power.
