Can alumina production assist greenhouse gas emissions?
The production of alumina into lightweight aluminium does have a number of long term benefits in reducing greenhouse gas emissions. For example, aluminium is most commonly used in the manufacture of motor vehicles and it is estimated that for every kilo of lightweight aluminium used in a car will save 20 kilograms of greenhouse gas over the life of the vehicle because less energy is required to fuel the vehicle. It is also estimated that each kilogram of aluminium used in a long haul truck can save 200 kilograms of greenhouse gas over the truck’s life.
