The iPhone maker has been taking steps to
reduce its use of the carbon-intensive metal that emits direct greenhouse gases
from the smelting process and has spiked consumer, activist, and investor
dissent due to its environmental impact.
Apple first bought a smaller batch of the
lab-made metal in 2019 from Elysis, a Montreal-based joint venture between two
of the world's biggest aluminium suppliers - Alcoa and Rio Tinto. It had used
the metal in its 16-inch MacBook Pro.
Elysis had originally planned to
commercialise its technology, which uses a ceramic anode to make aluminium and
emits only oxygen, by 2024. © Reuters
