Innovative technology that uses algae to convert waste coal dust into a clean, high-quality coal which can readily be processed into biofuel was publicly demonstrated at the Nelson Mandela Metropolitan University in Port Elizabeth on Monday.

“If you mix coal dust and algae biomass, the algae adsorps [collects] onto the surface of the coal and binds the dust together,” InnoVenton’s Professor Ben Zeelie said. The result is a coal-algae composite [briquette or pellet], for which they’ve coined – and trademarked – the name “Coalgae”.
