Today in Vietnam, cashew nuts is one of the main industrial crops and most Vietnamese companies export cashew nut oil as raw material. However, the oil could also be used for making adhesives, anti-corrosive metal, insulating materials, electronic product panels, forest products preservatives and wood-treating processing liquids and could even produce fuel 60% cheaper. Indeed, Carnadol this natural phenol obtained from Anacarditic acid, the main element of cashew oil, is very effective against corrosion of metals and could be extremely useful on continents where the weather is hot with high humidity, like Asia, where the demand for substances capable of protecting construction work, machinery and equipment against corrosion is particularly high.





However, after harvesting and processing cashew nuts, the shells are usually discarded. Today Vietnamese scientists believe that if shells could be properly treated they could also be used. A ton of dried cashew can produce 700-750 kilograms of shells giving 154 kilos of cashew oil. Vietnam is now the world’s third largest producer of cashew nuts behind India, and the Ivory Coast and is the world’s biggest exporter with an annual growth of 5.6% in volume and 18.4% in value. The export of this nut, including its derivatives, generated $ 3.1 billion in 2016. Will Vietnam become the world’s production base for cashew nut oil in the very next future?
