Jatropha



The Plant (Jatropha curcas L.) is a shrub or small tree which is planted in tropical and subtropical countries as a living fence to protect gardens and fields from animals. It produces small seeds which contain more than 30 % of a nonedible oil.

The Products are oil, press-cake and the sediment of oil purification. The oil can be used as fuel in pre-combustion chamber diesel engines and as lubrificant, the oil and the sediment can be used for soap production and the press cake is a good organic fertilizer. The oil contains also an insecticide.

The Oil Extraction can be done with hand- or engine driven expellers. These are simple machines, which can be operated on village level and built within the country.
