THE SCIENCE INSIDE - Anaerobic digestion

The Council for Scientific and Industrial Research is working on a study that will help municipalities manage wastewater through their municipal beneficiation project. The project aims to harness energy through a process called anaerobic digestion. They are also investigating how they can salvage biogases produced by human and bio waste, recover lost water in sludge and better manage wastewater. CSIR researcher Khuthadzo Mudzanani, talks about the practicalities of the research and its impact.

On Unscience, we look at an interesting study, which suggests that sleep deprived people are more likely to opt for foods and diets with a higher calorie count.

In our final story, we speak to the Head of Department of the Centre for Environmental Management, at the University of the Free State, Prof Paul Ober-holster. He chats about how they together with the CSIR have successfully implemented an algae-based wastewater treatment solution at the Motetema wastewater treatment works in the Sekhukhune District Municipality in Limpop
