Better Metal - refining steel without producing CO2

"Boston Metal, which is developing a process to reduce carbon emissions in steel making by using electricity instead of traditional pollution-heavy techniques...uses a process called metal oxide electrolysis, which allows pure metals to be produced without carbon emissions. The only byproduct is oxygen."
