ANACARDIUM OCCIDENTALE

The Cashew, Anacardium occidentale L., is a member of

the Anacardiaceae family, along with mango, pistachio,

poison ivy and poison oak. Cashew is native to north-

eastern Brazil, in the area between the Atlantic rain forest

and the Amazon rainforest.

Anacardium Occidentale is largely produced in India, Viet Nam, Africa, Brazil ...

Cardanol based products

PolyolBiofuel

CNSL (Cashew Nut Shell Liquid) is obtained as a by-product from cashewshell ’s treatment (mainly by squeezing or solvent extraction); it represents anuseful, cheap and renewable starting material. It can be used as such for lowvalue applications or subjected to further transformations.

CNSL’s and cardanol’s current main usesField of interest Application

Coating sector Industrial and marine coatings

Paint (anti corrosive) and enamels, varnishes rubber industry to enhance thevulcanisate propertiesLacquers developed from CNSL could be used for insulation, protective ordecorative coatings for furniture, buildings, automobiles, etc.

In the coating arena, cashewnut shell oil is used as a key raw material in theproduction of curing agents for special epoxy hardeners and epoxy resins

Construction sector For cementing floors exposed to chemical attackLaminating industry For reducing brittleness and improving the flexibility of the laminates

Substitute As a substitute for linseed oil in the manufacture of foundry core oil, which isused as a binder in the foundry

Automobile Auto brake lining

Current applications are generally characterized by low added value

A real sustainable development needs products with lighter Ecological Footprint.The lower Global warming potential (GWP), the lighter the EcologicalFootprint

Polyol GWP (kg CO 2)Petrol polyol 4,10Soy polyol - 1,40Polyol from Cashew nuts - 5,91

If we substitute 1 ton of petrol polyol with Polyol from Cashew nuts, we save 5,91 tonof CO 2, equivalent to:

q the emission of 1 person flying from Brazil to Italy and back

q the emission of 30.000 km driving by car

Global warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. Itcompares the amount of heat trapped by a certain mass of the gas in question to the amount heat trapped by a similarmass of carbon dioxide . A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years. GWP is

expressed as a factor of carbon dioxide (whose GMP is standardized to 1). For example, the 20 year GWP of Methane is56, which means if the same weights of Methane and carbon dioxide were introduced into the atmosphere, that Methanewill trap 56 times more heat than the carbon dioxide over the next 20 years.
