Next generation technologies

Our AP technology platform is the world's cleanest aluminium production technology. We are committed to its continuous improvement and to developing a greener, more efficient aluminium production process.

Our goal is to reduce and eventually eliminate emissions, and dramatically reduce energy consumption.

Approximately 7,500 AP series cells are already in operation worldwide, representing some six million tonnes of installed capacity. In comparison to other smelting technology, our AP platform leads in terms of:

• Highest installed capacity worldwide
• Lowest greenhouse gas emissions
• Lowest energy consumption
• Lowest full economic cost
• Highest productivity

AP30: We are constantly investing to improve the performance of our already highly successful AP30 technology platform.

AP50: In Quebec, Canada, the first metal from our AP50 pilot plant is expected in 2010. AP50 features the world's highest productivity cell design, providing an ideal platform to improve energy efficiency.

Rio Tinto Alcan's proprietary AP3X smelting technology is the aluminium industry's leading technology in terms of energy efficiency and lowest emissions. This lead will be extended in the coming years with the arrival of the next generation AP50 technology.
