I am working at KWS (Kenya Wildlife Service) in Malindi, as a volunteer of JICA. My job is teacher of environment. This presentation is about introduction of how to make ecology soap by used oil. In Kenya, people love to eat chips. However, after fry chips, the oil will go to sewage directly. Therefore, I introduced how to make soap by wasted oil.
