Brimstone

Brimstone is reinventing how the world's essential materials are made—and building the Fourth Great Refinery to do it. The Brimstone Rock Refinery® is a patented co-production process that refines a single, globally abundant rock into cement, supplementary cementitious materials (SCM), alumina, steel, aluminum, magnesium, titanium, and more. For the first time ever, these materials can be produced together, cost-effectively and efficiently, through one integrated process—transforming global supply chains and unlocking a new era of material abundance.
