Energy efficient and eco-friendly aluminum production

2017 - 2020

Aluminum smelting without releasing CO2.


Aluminum production is an energy intensive process that requires extraordinary amounts of electricity, water and other resources. So much energy is required that often dedicated power plants are built just to support an aluminum smelter. Unfortunately, much of the energy required to produce aluminum comes from coal, one of the most polluting fuels known to mankind.

This project delivers an environmentally friendly and energy efficient solution to our aluminum production needs. This solution originates at Icelandic company Arctus Metals, ehf. where they have developed and patented a new process that is carbon neutral in which no CO2 or other greenhouses are emitted. For comparison, the traditional Hall-Héroult aluminum production method generates 1.5 tons of CO2 per ton of aluminum produced. In other words, this method results in more pollutants than value for society. In contrast, Arctus Metals’ new method generates 1 ton of oxygen per ton of aluminum produced, that is, no CO2 is generated at all.
