Castor Oil Cake is a valuable by-product obtained by crushing castor seeds in an expeller under controlled temperature with the help of steam. Rich in nitrogen and essential nutrients, this organic residue serves as an excellent natural fertilizer, widely used in sustainable and organic farming practices.
In addition to its agricultural use, Castor Oil Cake also retains some residual oil, which can be further extracted in solvent extraction plants, making it a dual-purpose raw material.
