Elysis

The roughly 70 million metric tons of aluminum produced each year generate about 3% of global industrial carbon dioxide emissions. Now, in Quebec, aluminum giants Alcoa and Rio Tinto have begun operating the first commercial-scale, carbon-free aluminum plant. The technology behind the venture, Elysis, replaces the carbon anodes typically used in aluminum smelting with a proprietary material, eliminating direct greenhouse emissions from the process. “It brings benefits not only to the environment, but through more efficient production of aluminum,” says Elysis CEO François Perras. Look for Elysis-made aluminum in Apple MacBook Pros and iPhones, BMW and Audi vehicles, Corona beer cans, and aerosol cans from Ball, Unilever, and Alcoa.
