Cement makers advance carbon capture

Lafarge and Heidelberg select technologies for CO2 capture and utilization projects Two construction-material firms have selected technology partners for facilities that will capture and use some of the carbon dioxide generated at their cement plants. In British Columbia, Lafarge is adding a CO2-to-chemicals system from the start-up Dimensional Energy to CO2-capture pilot equipment from Svante that has operated at its Richmond Cement Plant since January 2021. Svante captures CO2 with solid sorbents based on metal-organic frameworks. When completed, the system will pull 1 metric ton (t) of CO2 per day from Lafarge’s cement facility and react it with hydrogen to yield roughly 180 L of hydrocarbon waxes. ... Read more in C&EN
