Carbon-free Aluminum

Aluminum is carbon-intensive to produce. The smelting process involves passing electrical current through a large block of carbon called an anode, which burns off during the process and releases carbon dioxide into the atmosphere.

The carbon-free move is a response to consumer, activist and investor demand that miners and manufacturers show they are working to lessen their impact on [cl*m*t* ch*ng*].

“For more than 130 years, aluminum – a material common to so many products consumers use daily – has been produced the same way. That’s about to change,” Lisa Jackson, Apple’s vice president of environment, policy and social initiatives, said in a statement.

Apple uses aluminum housings for many of its electronics, including iPhones, Apple Watches and Mac computers. Apple last year introduced Mac models that use recycled aluminum.

The Alcoa-Rio joint venture wants to commercialize a technology by 2024 that uses a ceramic anode to make aluminum and emits only oxygen, eliminating direct greenhouse gas emissions from the smelting process.
Five more days until we can talk about the implications of this, but this appears to be a fundamental shift in a 130 year old industry. By a consortium of aluminum companies, Apple and Canadian governmental bodies.

Similar to carbon negative concrete. It's too bad the world is going to stainless steel.
