In 2015 NZAS produced a hot metal record of 335,292 tonnes of aluminium
NZAS has one of the lightest carbon footprints per tonne of aluminium of a smelter anywhere in the world. We are proud to have our metal marketed under the new Rio Tinto RenewAl brand. Under this umbrella, NZAS can take advantage of international demand for greener, more sustainable, low-carbon products.
RenewAl metal is externally certified to have smelting emissions of less than four tonnes of CO2 per tonne of aluminium. This guarantees that the aluminium is made from traceable raw materials and is produced with electricity from low carbon sources, using world class smelting processes.
NZAS is one of a handful of smelters which can market under the RenewAl brand. We produce a wide range of value added products, including speciality billets, high purity ingots, and foundry alloys that are cast from low carbon aluminium. NZAS is a responsible supplier producing consistently high quality products with one of the lowest CO2 footprints in the world.
