[ti:Cameroon Chemist Recycles Used Cooking Oil into Cleaning Products]
[00:00.04]A chemist from Cameroon has found a way to recycle used cooking oil
[00:07.25]so it does not end up polluting the environment.
[00:13.08]Martial Gervais Oden-Bella makes soap and other cleansing products
[00:19.76]out of cooking oil from hotels and restaurants in the southwestern city of Douala.
[00:28.72]Most of the businesses used to pour all their oil waste into drain pipes.
[00:36.84]Scientists say if used oil is poured down drains or released into nature,
[00:44.49]it can pollute water treatment systems and the environment.
[00:50.60]The oil waste can also harm animals.
[00:55.84]Oden-Bella told VOA he got the idea of recycling used cooking oil
[01:02.38]after hotel officials recognized the huge amount of oil their business was using.
[01:10.88]The hotel used to release all its cooking oil waste into the environment.
[01:16.76]But officials were concerned about the harmful effects this was having.
[01:23.68]Oden-Bella thought about a possible solution
[01:27.39]and developed a way to create cleansing products from the used oil.
[01:34.12]He launched production in 2014.
[01:37.56]Today, he operates a business that produces 165 kilograms of soap
[01:45.36]and two tons of liquid detergent each month.
[01:51.08]Even small businesses have joined in recycling their old cooking oil.
[01:57.28]Adeline Monkam makes donuts in Douala.
[02:02.16]In the past, she threw out her store's used oil.
[02:07.04]But after learning that this can pollute the environment,
[02:10.67]Monkam decided to recycle the oil.
[02:15.00]Frantz Tafongang is an environmental scientist
[02:19.38]who leads Biotex Laboratory, which recycles used oil.
[02:26.28]He told VOA the recycling operation reduces pollution
[02:31.24]while creating new and valued products.
[02:35.92]Tafongang said waste oil can be harmful if swallowed directly.
[02:41.66]But if recycled, the oil can be used to produce safe personal care products, he said.
[02:50.08]Biotex Laboratory said hotels in Douala alone
[02:54.47]produce about 20,000 liters of waste oil each month.
[03:00.88]Oden-Bella says too much of that oil is still being thrown away.
[03:06.50]He is calling for increased public education
[03:10.08]to show people how used cooking oil can be recycled into useful products.
