Furno Materials

Furno Materials is a California cleantech company rebuilding how cement is made. Instead of the mile-long rotary kilns that make cement one of the dirtiest industries on earth - roughly 8% of global CO2 - Furno builds compact, modular vertical micro-kilns (the 'Furno Brick') that run at more than 80% thermal efficiency, roughly double a conventional plant. The kilns burn gas-based fuels, eliminate NOx and SOx emissions entirely, cut fossil-fuel emissions by at least 70%, and can reach zero emissions on hydrogen - all while producing standards-grade Ordinary Portland Cement at the point of demand.
