To promote renewable energy as a cost-effective technology in a world facing the impact of climate change and global warming, the University of South Africa, diversified miner Exxaro Resources and the South African National Energy Development Institution on Wednesday launched its first institutional anaerobic digester at nonprofit organisation EARTH Centre’s premises, in Johannesburg. Making use of a sustainable water supply, including grey water, these anaerobic digesters will be used as a source of fuel for cooking in households, schools and community organisations, and will not only vastly improve people’s standard of living but will also help the environment by minimising organic waste.
