Researchers at the Walloon Agricultural Research Centre of Gembloux, Belgium, are testing a new fuel in Senegal.
Researchers at the Walloon Agricultural Research Centre of Gembloux, Belgium, are testing a new fuel in Senegal. Dubbed Bioterre, it is made of agricultural waste products (coffee, rice husks, etc.) and comes in the form of pellets made by grinding the waste and mixing it with clay and water. The pellets are then granulated before being left to dry in the sun and packaged. This process enables the fuel to be adapted to both domestic and small-scale industrial usage, by modifying the composition or size of the pellets. According to project organisers, the use of 1,000 t of rice pellets can save up to 400 ha of forest. What is more, in Senegal, where a production unit has been installed, the fuel sells at CFAF60/kg ( 0.10), while charcoal costs CFAF212/kg ( 0.32). A survey carried out in some 30 Senegalese households revealed that 90% of them are willing to use Bioterre instead of charcoal. Before they can make the change, however, families must first invest in a specially converted kiln at a cost of CFAF7,000 ( 11). If the system is to become more widely used, production costs will first need to come down, both for the fuel and the kiln.
