Various materials are used during production process at each business unit of Antam, according to type of product to be produced. None of the material used originated from recycling process from the third party, however there are disposed materials from production process which are reused after being processed by the unit.

In limited capacity, Antam has recycled part of the material in production process, and the recycled materials are not from the consumers. The recycled materials to be reused at UBP Gold Pongkor were water and cyanide (CN) residue from cyanide process. Water reuse was through recirculation mechanism, in which water from tailing dam was pumped to the process water tank of the plant to be reused. The effort of reusing materials for production process was also applied at UBP Nickel Southeast Sulawesi, by recycling the waste which still contained nickel component to be used as nickel ore substitution.
