US: The government has awarded a US$3.24m grant to Washington State University (WSU) for its research towards the development of reduced-CO₂ cements. The research is investigating new formulations, in combination with novel technologies aimed at eliminating CO₂ emissions. WSU is one of 40 recipients of a funding pot worth US$135m.

Energy Secretary Jennifer Granholm said "America’s industrial sector serves as the engine of the US economy, producing many of the products we rely on every day, but it also produces a significant amount of the nation’s carbon emissions. These projects funded by President Biden’s Investing in American agenda will slash industrial emissions and accelerate next-generation technologies for a clean energy future that’s made in America.”

US: A team from Washington State University (WSU) and Pacific Northwest National Laboratory has successfully used waste crustacean shells in the production of concrete. ZME Science News has reported that the materials consist of calcium carbonate and 20 – 30% chitin, a nanoparticle biopolymer. When used as an additive in concrete production, the shells increase the set product’s compressive strength by 12% and its flexural strength by 40%. The team is now developing a methodology for the industrial-scale production of shell-based additives.

WSU researcher Professor Michael Wolcott said “Those are very significant numbers. If you can reduce the amount that you use and get the same mechanical function or structural function and double its lifetime, then you’re able to significantly reduce the carbon emissions of the built environment.”

US: A research team at Washington State University has developed admixtures using chitin derived from seashells. The Moscow-Pullman Daily News has reported that the substance enhances concrete’s performance when substituted for some of the cement content. The lower clinker factor may also decrease net emissions. Work has shown that lower volumes of the supplementary material are required compared to existing admixtures.
