02 October 2024
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.

US: The Global Cement and Concrete Association (GCCA) has launched the sixth annual Concrete in Life photography competition for 2024 – 2025. The launch coincides with The Climate Group’s New York Climate Week (NYCW) 2024. The GCCA will receive photo entries showing concrete’s sustainability, beauty and vitality, and a panel of judges will award a US$10,000 prize to the best. Past entries are currently on display in New York, US, at the One Vanderbilt building.
GCCA CEO Thomas Guillot said "The GCCA is leading pioneering work with our members to decarbonise our essential industry. Our Concrete in Life competition gives every community across the globe a chance to show just how essential concrete is to our lives and building a more sustainable world. It was important to give people attending NYCW a chance to see the role that concrete plays in supporting society and communities across the planet."
Judge and co-chair of design and architecture firm Gensler Diane Hoskins said "The places and spaces where we spend our time shape our experience of the world. Concrete is one of the most versatile and ubiquitous building materials, opening up an incredible opportunity for innovation and creativity. As architects and designers, we strive to achieve beauty, function and resilience in our work. This is the power and promise of the built environment and the materials that bring it to life."
Fellow judge Tina Paillet, president of the UK-based Royal Institution of Chartered Surveyors (RICS), said "As the globally renowned professional body for the built and natural environment, RICS members know just how important concrete is to modern infrastructure and to meeting the world’s net zero targets via the circular economy. I’m looking forward to judging this year’s Concrete in Life competition and getting the chance to see many awe-inspiring photographs from around the world."
