Cashew "oil" usually means Cashew Nut Shell Liquid (CNSL) — a valuable industrial oil extracted from the shell by roasting/expelling or solvent methods, not the edible kernel.
When people say "cashew nut oil", they usually mean Cashew Nut Shell Liquid (CNSL), the dark caustic oil held in the honeycomb of the cashew shell — an industrial feedstock, not an edible oil. CNSL is extracted from shells by mechanical expelling (often after roasting) or by solvent extraction. It yields cardanol and other compounds used in resins, brake linings, paints and specialty chemicals. Recovering CNSL turns cashew shell — otherwise a waste or fuel — into an additional revenue stream.
CNSL and its derivative cardanol are covered in more depth under Cashew Nut Shell Liquid (CNSL).
CNSL is caustic and industrial. It is distinct from any edible oil; the cashew kernel itself is generally sold as a nut, not pressed for oil.
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.

Cardanol is the main phenolic compound distilled from CNSL — a renewable, bio-based building block for resins, plasticisers, coatings and green chemistry.
Open →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.
Open →The cashew husk — the hard outer covering removed during shelling — is, like the shell, a biomass fuel and CNSL feedstock rather than waste.
