Regain maximises the value of residual mineral by-products from aluminium smelting. These by-products include refractory from bake furnaces, carbon from anodes and the carbon & refractory materials from spent potliner. By maximising the value of these by-products Regain provides the smelter with the lowest cost option for responsible management of residual by-products.

Aluminium smelters are not all alike. Production processes and handling methods differ and the residual by-products vary from smelter to smelter. Regain analyse the carbon, refractory and other smelter by-products to establish appropriate markets and re-use options for the materials along with the optimum processing methods.

Regain has three main objectives in its relationships with the aluminium smelting industry:

• 100% beneficial use of smelter mineral & metal by-products, with no unwanted residue
• A significantly positive effect on the environment
• Community, government and industry recognition of the aluminium smelter as a leader in responsible and sustainable management of by-products.
