Between the 8th and 20th October, 42 volunteers learn all the techniques to construct and use efficient wood stoves. The volunteers come mainly from two semi-rural areas of the city Kinshasa. The efficient wood stoves are made of clay, straw and cow dung. All ingredients are sustainable and have a positive effect on the development of the site. The workshop is organized by Greenpeace Africa and the Youth Support Center of Greenpeace Switzerland.
