Before processing, the bone is cleaned to remove foreign materials. Then it is crushed to facilitate further processing. Fat is extracted using gasoline as a solvent. The next step is the separation of glue. Glue is extracted by boiling bone under 1.5 – 2.0 bar steam. The last step is
the chemical transformation of the tri-calcium phosphate (the bone material from which fat and glue were removed) to normal super phosphate. This is achieved through the reaction of bone with sulphuric acid. The NSP is finally granulated into the required size and packed in paper bags of 50 Kg.

Currently, there is no alternative technology to produce NSP from crushed bone.
