CRH Ventures has made a strategic investment in Sublime Systems, aiming to advance decarbonization efforts in the cement industry through innovative sustainable production technologies.

Information on the Target

Sublime Systems is a leading U.S.-based company specializing in sustainable cement manufacturing. The company has developed an innovative electrochemical approach to cement production that operates at near-ambient temperatures, which presents a groundbreaking alternative to traditional, energy-intensive kiln processes. By focusing on utilizing calcium-rich minerals and various industrial byproducts, such as slags and kiln dusts, Sublime Systems is capable of producing hydraulic cement compliant with ASTM C1157 standards, serving as a direct substitute for portland cement in concrete applications.

One of the most significant advantages of Sublime Systems' technology is its potential to reduce carbon dioxide emissions from cement production by up to 90% when fully commercialized. This reduction is achieved through a unique process that breaks down solid feedstocks into their elemental components, allowing for the creation of other valuable industrial co-products while minimizing waste.
