"A teenage student at the school came up with a solution: Why not turn the sewage, along with food waste and dung from the school's cattle, into power for the school?"
"My inspiration was drawn from the pressing demand for a clean, renewable sustainable source of fuel," says student Leroy Mwasaru, now 17. "In the African continent we have lots of resources that masquerades as 'waste.'"
"Along with a team of fellow students, Mwasaru started researching biodigesters—underground chambers that collect waste and use microorganisms to efficiently convert the waste into a renewable fuel. 'We were out to make ours more flexible and better,' Mwasaru says."
