Starting in Q1 2023, this first commercial scale deployment of TCRK CCUS technology will initially target 30,000 tCO2e per year, growing to 120,000 tCO2e per year over the first 18 months. This second target will provide 20% of the emission reductions Asia Cement requires to meet its decarbonisation commitments at the plant by 2025. TCRK and Asia Cement will look to continually expand the capture rates.
TCRK’s novel CCUS based strategy for the decarbonisation of cement production will employ two processes to use the captured carbon from the current cement production processes to produce a lower-carbon cement product and to cultivate microalgae for biomass.
TCRK’s innovative Arago Cement Process uses captured CO2, cement kiln dust and by-pass particles to produce precipitated calcium carbonate, which TCRK uses to produce a carbon neutral cement product called Arago Cement. This reduces emissions from the industrial processes used to produce the cement with the added benefit of significantly reducing the problem of disposal and landfilling of kiln dust. The process provides a long-term carbon store in the cement produced, and TCRK is currently working to demonstrate the life-cycle benefits of reducing the emissions of harmful cement by-products.
TCRK’s collaboration with Asia Cement will also use captured CO2 to grow microalgae, in a process called bio-fixation. This method will offer 10% extra carbon storage capacity. The microalgae has a wide range of potential end-products including bioplastics and animal feed, and can also be used as a source of bio-cement production. This offers opportunities to displace emissions in other sectors by avoiding higher carbon production processes.
Byung-Chul Kim, Head of TCRK in Korea, commented, “This collaboration with Asia Cement is strategically important in demonstrating the commercial scalability of TCRK’s proprietary technology and in reducing the carbon footprint of one of the hardest-to-abate industries. We are excited to be scaling-up our innovative bio-fixation and calcification technologies to a commercial level, working alongside a leader in the cement industry.”
