Sept 18 : Italian cable maker Prysmian said on Friday it had partnered with Rio Tinto to supply electrical cables made with low-carbon aluminium for an Amazon data centre in Ohio.

The cables will use aluminium produced with ELYSIS "inert-anode" technology, which Prysmian said eliminates direct greenhouse gas emissions from the smelting process, releasing pure oxygen instead.

• Project is the first known use of inert-anode-smelted aluminum in a data center, the company said.

• "The use demonstrates that the carbon footprint of data centers can be reduced at the raw material level," it added.
