Japan: Taiheiyo Cement says it is progressing with its C4S project to develop a novel concrete imbued with CO₂ from direct air capture (DAC). The project is a collaboration with the University of Tokyo, with support from the Japanese New Energy and Industrial Technology Development Organisation (NEDO). Taiheiyo Cement says that concrete developed by the partnership aids faster CO₂ capture via DAC, increasing strength, confirmed seismic resistance and carbon neutrality per full life-cycle assessment.

Taiheiyo Cement says that the eventual certification of DAC-carbonated concrete will play a significant role in the decarbonisation of the Japanese construction sector.

Indonesia: Cemindo Gemilang says that its subsidiary Merah Putih Beton has begun injecting CO2 captured using direct air capture (DAC) into its ready-mix and precast concrete products. The producer said that the method enables it to produce concrete using 18% less cement. The Koran Jakarta newspaper has reported that Cemindo Gemilang obtained the DAC technology under licence from its Canada-based developer. It deployed it following six months of trials in late 2023 – early 2024.

Cemindo Gemilang’s commercial director, Surindro Kalbu Adi, said “In the future, we will implement a lot of new technologies. The goal is that our Red and White brand products will be better and the quality of buildings will be even better.”

US: Block-Lite plans to install a system to cure concrete blocks using direct air capture (DAC)-sourced CO₂ at its Flagstaff, Arizona, concrete block plant. The upgrade will implement CarbonBuilt’s low-CO₂ concrete production technology and AirCapture’s modular DAC technology, across five or six capture units. Direct air capture will thus remove 500 – 600t/yr of CO₂ from the atmosphere, while process changes will reduce CO₂ emissions from the Flagstaff plant by over 2000t/yr. The project has attracted fundraising from the 4 Corners Carbon Coalition (4CCC), with a goal of US$50,000. The Arizon Daily Sun newspaper has reported that Block-Lite plans to supply its first shipment of low-CO₂ blocks to a 50-home development by Habitat for Humanity in Flagstaff.
