Chemist Martial Gervais Oden-Bella developed a method for recycling used cooking oil by turning it into soap! Not only is he helping the environment, but he’s made a profitable business in the process.
In Cameroon, people were tossing the used oil down the drain, which can pollute water treatment systems and the environment. When the oil ends up in the environment, it’s harmful and toxic to wildlife. Now the businesses (restaurants and hotels in the southwestern city of Douala) save the used oil to give to Oden-Bella, who turns it into soap and other cleaning products.
