Company Description

Boston Metal is a company developing a technology platform called Molten Oxide Electrolysis (MOE) to produce metals with no direct carbon emissions. The process, which operates at 1600 °C, uses electricity to separate metal from ore and can be applied to both steel production and the recovery of valuable metals from mining waste. The company runs a pilot plant in Woburn, Massachusetts, and has a wholly owned subsidiary in Brazil deploying MOE for critical metals. Founded between 2012 and 2013, Boston Metal has focused on advancing its technology from its early stages to commercialization.

Looking forward, Boston Metal is focused on scaling its MOE technology from the laboratory to industrial-scale applications for both green steel and critical metals. The company has received several recent recognitions, including an induction into the Global Cleantech 100 Hall of Fame after being selected for the list seven years in a row. Its subsidiary, Boston Metal do Brasil, was named Mineral Sector Company of the Year by Brasil Mineral. Additionally, the former CEO of Alcoa, Roy Harvey, was appointed to the company's Board of Directors. The company is also undertaking environmental projects, such as planting thousands of seedlings in Brazil to help recover native vegetation.
