Brimstone aims for industrial revolution with cleaner cement and critical mineral process

By PulseAugur Editorial · [1 sources] ·

Brimstone, a US-based climate tech startup, is developing a novel process to simultaneously produce cleaner cement and extract critical minerals from a single type of rock. This approach aims to reduce emissions from cement production by approximately 60% and provide a domestic source for materials like alumina, steel, and magnesium, which are currently largely sourced from China. While the company has received industry certification for its cement production, it faces significant challenges in scaling to commercial production and securing funding, including a previously revoked $189 million grant from the Trump administration.

    Brimstone and its one-stop process for making cleaner cement and critical minerals

    Brimstone is making strides on two industrial problems, reducing the emissions from cement and providing a way to produce more critical minerals within the US. If the company can do both, with the same rocks in the same plant, it would unlock a cleaner and more efficient process …
