Jatropha Byproducts - Creating Additional Value
In addition to producing high quality biodiesel, the processing and refining of jatropha seeds also produce valuable byproducts. D1 is researching how the production of these byproducts can create added value for growers and refiners. Efficient use of byproducts ensures that jatropha growing and processing is more profitable and produces zero waste.

When jatropha seeds are crushed to extract their oil, the husks and other residues are left behind as seedcake. Jatropha seedcake is high in protein and other nutrients, and has a wide variety of applications as both an organic fertiliser and nutraceutical. Further processing can turn the seedcake into high protein animal feed. Jatropha seedcake also has a high energy content and can be pressed into briquettes and burned as fuel. Farmers who harvest and process jatropha seeds can use the seedcake in a wide variety of ways to support their operations.

Refining crude jatropha oil into biodiesel produces glycerine, which is in demand as a raw material for a very wide range of cosmetic, medical and food products. Glycerine byproducts from biodiesel production offer a valuable additional income stream to refiners.
