The significant funding awarded to Queens Carbon by ARPA-E highlights the critical need for innovative solutions in the cement industry to address CO2 emissions. Queens Carbon's approach of developing carbon-neutral supplemental cementitious materials (SCM) from industry-standard raw materials is a promising step toward sustainable construction. The deployment of a pilot plant capable of producing 10 tonnes of SCMs daily marks a crucial milestone in scaling this technology. If successful, this could pave the way for widespread adoption and substantial reductions in greenhouse gas emissions in the cement and construction sectors, making it a key player in the global effort to combat climate change.
