Description

Several methods are available in the literature for the extraction of CNSL. Oil extraction efficiency varies with the method adopted. Raw CNS has been reported to contain over 20% oil. The oil bath process leaves about 10% of the oil as a by-product in the spent shell. However, using an expeller extraction process, further quantities of oil may be recovered from the spent CNS. Energy studies established that cashew nut by-products CNSL, its isolates and spent CN Shell compare quite favourably with conventional fuels in terms of energy content. CNSL, cardanol and cardol, which are liquid by-products, were superior to conventional liquid and solid fuels while spent CNS was more superior to a number of liquid fuels, e.g. ethanol and methanol, as well as fire wood in terms of energy content. This material is advocated for use by cashew nut processors and other industries as fuel to reduce environmental pollution. This material is not only a cleaner fuel but also has low ash and is renewable.
