No. 565: Japanese technology for malaria control grows widespread in Africa (July 18, 2012)

More than one million people are reported to be killed by malaria every year in Africa, and 90% of them are inhabitants in the Sub-Saharan Africa that is the area to the south of the Sahara Desert. A mosquito net named Olyset Net developed by Sumitomo Chemical is growing widespread in the Sub-Saharan Africa, and the company established the “Africa Technical Center” inside its Tanzanian plant. Staffed with about 30 local staffs, the center plans to develop and commercialize an agricultural net that maintains the moisture of farmlands by blocking the air by applying the Olyset Net by 2014.

The Olyset Net is a net sewn with threads made of resin into which repellent is kneaded. Because the repellent steeps to the surface gradually, the insecticide efficacy of the Olyset Net lasts for more than five years even if it is washed repeatedly. The company started local production of the Olyset Net in Tanzania in alliance with a local company in 2003 and established a joint company with it in 2007. The plant has now an annual production capacity of 29 million Olyset Nets. The joint company has been promoting the Olyset Net in alliance with the WHO and UNICEF, and the Olyset Net is being used in 36 African countries at present. Olyset Net was selected as the “world coolest technology” by Time magazine in 2004. It has 35% share in the mosquito net market in Africa at present.
