News Brimstone produces carbon negative ordinary Portland cement from calcium silicate

Brimstone produces carbon negative ordinary Portland cement from calcium silicate

US: Brimstone has announced a new method of ordinary Portland cement (OPC) with a negative carbon footprint. Brimstone's method uses carbon-free calcium silicate in the place of limestone. Its calcination also produces magnesium compounds, which naturally sequester further CO2 from the atmosphere. The technology will now proceed to the testing phase at an upcoming pilot plant in Reno, Nevada, before proceeding to commercial-scale production. Brimstone will then begin to market its OPC, along with supplementary cementitious materials produced by its process.

Brimstone's chief technology officer Hugo Leandri said “By delivering the exact same cement, we clear away the main obstacles to adoption, offering an opportunity to dramatically speed up the path to net-zero construction. The same buildings, bridges and roads being built today can be built tomorrow, without carbon."
