Leroy Mwasaru

Position: Greenpact


As a high school student of Maseno School, Young Leroy Mwasaru started Greenpact when his school faced a problem of a faulty sewer system. The sewer problem polluted nearby sources of domestic water for the neighboring community, sparking a demonstration against the school. In a bid to provide a solution to this problem, Leroy and his classmates created a human waste bioreactor that utilized both human and organic waste to produce Biogas and organic fertilizer.
