Cashew Nut Shell Residue

Cashew nut shell residue, also known as waste or cake, refers to the fibrous material that remains after the extraction of cashew nut shell liquid and cashew kernels (cashew oil). In the field of agriculture, this residue can be utilized as organic mulch or compost to enhance soil structure and nutrient content. Additionally, it can be used as a supplement for animal feed, providing a source of roughage and essential nutrients. Due to its flammable nature, cashew nut shell residue can be easily combined with wood chips and other combustible materials to increase the heat in boilers. As a result, it is frequently employed as a fuel alternative to coal, firewood, and rice husks. In certain cases, further processing of the residue can extract additional compounds such as tannins, which find applications in industries like leather processing and wood preservation.
