Brimstone’s Alumina Story: A Game-Changer or Just Another Hype Cycle?

Another hype piece written by an investor in Brimstone, DCVC, highlighting the company’s recent pivot away from decarbonizing cement and toward whatever terminal form of optimism this is, involving the alumina industry. I assume this move comes as the Trump administration promises to cancel anything climate, and Brimstone feels their exorbitant $189M federal funding is vulnerable to cancellation on a whim if their project looks too “green.” Hence the pivot to strategic national supply chain for alumina.

The Role of Supplementary Cementitious Materials (SCMs) in Modern Construction

In the realm of construction, cement stands as one of the most critical components for creating durable and sustainable structures. However, traditional Portland cement production has been associated with significant environmental impacts due to its carbon-intensive nature. This is where supplementary cementitious materials (SCMs) play a transformative role by enhancing performance while reducing environmental footprints.

What are Supplementary Cementitious Materials?

Supplementary Cementitious Materials, or SCMs, refer to various by-products and waste materials that can be added to concrete to partially replace Portland cement. These materials not only contribute to the strength and durability of concrete but also play a crucial role in making construction more sustainable.
