Another link I found whilst surfing the Co-op’s intranet.
D1 Oils want to generate biodiesel from the seeds of the jatropha tree, a hardy shrub that can be grown all over the developing world.
Because it requires minimal rainfall, jatropha can be grown successfully on marginal, degraded, or even desert land. The trees also help prevent soil erosion. In addition to yielding oil for refining into biodiesel and glycerol for use by the cosmetics industry, the residual oil cake is excellent organic fertiliser. Research is underway into alternative uses for the residual seedcake, such as animal feed, briquettes for power generation and nutraceuticals.
