Cashew Husk Natural Byproduct for Industrial Fuel Fertilizer and Animal Feed Uses

Cashew husk, the hard outer shell of the cashew nut, serves multiple industrial and agricultural purposes beyond being a processing byproduct. Main Uses Fuel production: It's pressed to extract cashew nut shell liquid (CNSL), a natural resin used in biofuels, varnishes, paints, and friction materials like brake linings. Fertilizer: Ground cashew husk adds organic matter and nutrients (nitrogen, phosphorus, potassium) to soil, improving plant growth and acting as a natural mulch. Animal feed: After detoxification (removing toxic oils like anacardic acid), it's processed into livestock fodder, especially for ruminants.
