“Supergas” by Superflex. In 1997, Superflex installed and tested the first Superflex biogas system. The experiment was carried out at a small farm in central Tanzania, in co-operation with the African organisation SURUDE (Sustainable Rural Development). The plant produces approx. 3 cubic metres of gas per day from the dung from 2-3 cattle. This is enough for a family of 8-10 members for cooking purposes and to run one gas lamp in the evening.
