Policy-minded startups charter Decarbonized Cement and Concrete Alliance
Ten companies aiming to lower carbon dioxide emissions tied to cement production and finished concrete have launched a first-of-its-kind, U.S. coalition dedicated to growing awareness around policies that will accelerate the adoption of CO2-wise solutions in public construction. Founding Decarbonized Cement and Concrete Alliance (DC2) members are commercializing technologies that a) offer organic or inorganic alternatives for full or partial…

A screening life cycle assessment (LCA) validates how Sublime Systems’ low temperature, electrolysis-enabled processing of calcium-bearing feeds yields a concrete-grade binder whose global warming potential (GWP) is less than one-tenth that of a typical portland cement. The most widely referenced metric in environmental product declarations, GWP indicates carbon dioxide emissions and is expressed as kilograms per metric ton equivalent (kgCO2/mt). …
Read MoreSublime Cement performance measures up to ASTM C1157 standard
Sources: Sublime Systems, Somerville, Mass.; CP staff Third-party testing confirms that Sublime Systems’ namesake concrete binder, produced with sharply lower carbon dioxide emissions metrics than portland cement, exhibits strength development, durability, low shrinkage and other engineering properties matching or exceeding ASTM C1157, Standard Performance Specification for Hydraulic Cement benchmarks. In contrast to high temperature, fuel-intensive portland cement production, Sublime Cement…
