Zethos has developed and launched a revolutionary hydrogen reduction and electrochemical refining technology able to produce critical metals with 50% less cost and 95% lower carbon emissions. In zinc recycling from steel mill dust, the company’s beachhead market, Zethos has built a 10 T/year pilot plant, sold high-purity low-carbon zinc to market, secured signed commercial agreements worth over $500M USD and attracted $12M USD in funding. Zethos is now building a 1000T/y zinc capacity demonstration facility in New Zealand. Zethos is poised to reshape global metals refining while supporting decarbonisation across energy, transport, and manufacturing.
