Tunisia placed stakes on human resources in its innovative streak. The development of a new technique for extracting biodiesel from olive water (a black liquid formed at the beginning by water discharged from olives during oil extraction).
Developed by Dr. Kamel Halouani, who is working at the Sfax Preparatory Institute for Engineering Studies as teacher and researcher, this technique involve the extraction of oil devoid of acid and glucose, from olive water.
This innovation is likely to reduce discharges of olive water, which incidentally is rich in significant quantities in nitrogen, phosphorus, potassium and micro-nutrients. The olive water is a waste product of olive oil manufacturing and any biodiesel one gets out of the new process is money that would have been thrown away.
