Cashew tree cultivation is done primarily aiming cashew nut production. The large amounts of cashew shells are considered as agricultural waste and the by-product of cashew nut production. The cashew shell has high amount of oil content in it and can be used in various feedstocks. It is available in abundance during the summer in almost all parts of the world and is reported to possess high valuable products in utilization of food, medicine, chemical and allied industries. It is also useful as raw material for many industrial applications. However, the natural oil phenol, Bio-based monomers and various chemical structure of cashew nut have various ways in research and focused principally on the generation of significant worth included items. So as to understand the maximum capacity of cashew nuts and its mixes, information on preparing and use instruments fundamental deterioration is required. In the present paper, the creators made an endeavor to audit the writing on important use of cashew nutshell. Also, the cashew apple waste is used as a form of energy bagasse’s, fermented cultures used in probiotics also the waste is used for conditioning of soil. Initially cashew apple is full of vitamins and minerals so after extraction of juice some residue is left in it which helps in fermentation process further. The astringency containing tannin is manufactured by extraction from the cashew apple.
