The world's largest plant designed to suck carbon dioxide out of the air and turn it into rock started running on Sept 8, the companies behind the plant said.

The plant, named Orca, after the Icelandic word "orka" meaning "energy", consists of four units, each made up of two metal boxes, similar in appearance to the containers used for maritime transport.
