Why cardanol matters
- Renewable, bio-based alternative to petro-phenols
- Phenalkamine curing agents for epoxy coatings
- Resins, plasticisers and surfactants
Cardanol is refined from CNSL, itself extracted from cashew shell.

Cardanol from Cashew Nut Shell Liquid
Cardanol is the main phenolic compound distilled from CNSL — a renewable, bio-based building block for resins, plasticisers, coatings and green chemistry.
In short
Cardanol is a phenolic compound derived from Cashew Nut Shell Liquid (CNSL) by heating/distillation (decarboxylating anacardic acid). It is a renewable, bio-based chemical prized as a substitute for petroleum phenols: it goes into phenalkamine curing agents for epoxy coatings, phenolic resins, plasticisers, surfactants and other green-chemistry products. Because it comes from cashew shell waste, cardanol is part of the sustainability and value story of modern cashew processing.

Cashew Nut Shell Liquid (CNSL)
CNSL is a dark, caustic industrial oil held in the cashew shell. Rich in phenolic compounds like anacardic acid and cardanol, it feeds resins, coatings, brake linings and specialty chemicals.

Cashew Shell: Waste, Fuel and Feedstock
The cashew shell is not just waste — it is a fuel that powers the plant, a source of the industrial oil CNSL, and a feedstock for biomass energy and carbon credits.

Carbon Credits in the Cashew Industry
By burning cashew shell as biomass instead of fossil fuel, a cashew plant can cut emissions and potentially earn carbon credits — turning waste-to-energy into extra revenue.
