Brimstone is an Oakland-based startup developing a process to make cement using silicate rocks instead of standard limestone. This change reduces greenhouse-gas emissions by about 60% compared to conventional methods, which currently contribute roughly 8% of global carbon dioxide pollution. The company achieved third-party certification for this cement production in 2023, allowing its product to be used in standard construction projects.<\/p>\n

In early 2025, Brimstone announced it could also produce smelter-grade alumina from the same silicate rocks. Late last year, the company added that its single-refinery process can extract steel, magnesium, titanium, and other critical minerals. CEO Cody Finke stated these materials represent a $2.4 trillion global market and offer a domestic path for goods often produced in China.<\/p>\n

Despite these claims, Brimstone has not yet produced any materials at a commercial scale. The company faced a setback last year when the Trump administration revoked an $189 million grant intended to subsidize its next plant in Reno, Nevada. Finke says the company is having conversations about restoring those funds but believes it can proceed without them.<\/p>\n

Brimstone plans to begin operating its Reno facility in 2028, initially producing cement, supplementary materials, and alumina. The timeline for delivering steel and other critical minerals likely extends into the next decade. However, the company has already secured commercial deals with Amazon for cement and Century Aluminum for alumina.<\/p>\n
