Green Cement
Green Cement
As the cement industry seeks to meet their ESG targets, the key issue is the reduction of CO2 emissions. The application of new, carbon-neutral cement materials, termed “green” or “novel cement,” is the critical lever for addressing these emissions.
According to Chatham House (2018), “Significant changes in how cement and concrete are produced and used are urgently needed to achieve deep cuts in emissions in line with the Paris Agreement on climate change.”
The SonoAsh Solution
SonoAsh’s patented technology profitably enables the global cement industry to close the gap between today’s practices and their sustainability targets. Our technology operates at the intersection of legacy coal power waste and alternative cementitious materials.
Using waste coal ash as feedstock, our patented process transforms impounded coal ash into an engineered cementitious material with a significantly reduced CO2 footprint while also remediating problematic coal ash impoundments. The SonoAsh Sonicator reactor can process a broad range of coal ash samples to create engineered coal ash that meets ASTM C-618 (AASHTO M295 and European EN-450) requirements for high-value ordinary Portland cement (OPC) displacement.
