CO 2 Concrete is turning carbon dioxide (CO 2) emissions into construction materials and products without a need for carbon capture. Our patent-pending technology upcycles CO 2 with unparalleled efficiency, cost-effectiveness, and throughput into precast CO 2 …

4 days ago · Holding half its weight in carbon dioxide, the material could replace sand in concrete and other construction materials while trapping greenhouse gas. Credit: Northwestern University An innovative process converts CO2 into solid, durable materials that trap carbon. Using seawater, electricity, and carbon dioxide (CO 2), scientists at Northwestern University have developed a new carbon-negative ...

Mar 19, 2025 · Now, Northwestern’s new strategy addresses this challenge by locking away CO2 permanently and turning it into valuable materials, which can be used to manufacture concrete, cement, plaster and paint.

Jun 26, 2024 · By using a carbonated — rather than a still — water-based solution during the concrete manufacturing process, a Northwestern University-led team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.

Mar 24, 2025 · In carbonatable concrete, however, cement interacts with CO2 instead of water in a process called carbonation. This process absorbs CO2 into the material, making it more sustainable than traditional concrete. Carbonatable concrete also uses a different kind of cement, which requires less energy to produce and generates lower CO2 emissions.

Mar 25, 2025 · The quest for carbon-neutral concrete has become a billion-dollar endeavor – but a team of scientists from Northwestern gas gone one better.

Mar 25, 2025 · What does Terra CO2 do? Simply put: Terra CO2 is a Colorado-based startup that has developed a scalable, low-carbon alternative for replacing cement in concrete. The American startup produces supplementary cementitious materials and carbon-neutral cement to meet the vast demand, making decarbonized concrete a practical and accessible solution for the construction industry. Terra CO2 offers two ...

Feb 12, 2025 · In this blog post, we’ll provide an overview of CO2 injection technology, discuss the global importance of reducing emissions from concrete production and highlight several opportunities and challenges facing this nascent project type.

Jun 26, 2024 · Cement is a key constituent of concrete and offers a large sequestration potential of carbon dioxide (CO 2). However, current concrete carbonation approaches are hindered by low CO 2 capture...

Apr 5, 2025 · Researchers have made a groundbreaking paste that could help create carbon-capturing concrete in new construction projects.
