Name: Seratech Carbon-Neutral SCM
Address: London, UK

Carbon-neutral concrete sample made with Seratech silica SCM, permanently sequestering industrial CO2 emissions within its mineral structure.

The Material: Spun out of Imperial College London, Seratech has developed a groundbreaking carbon capture and utilization (CCU) technology that produces truly carbon-neutral concrete. Traditional cement production emits vast amounts of CO2. Seratech intercepts this process by capturing industrial CO2 emissions directly from flues and reacting them with olivine, an abundant naturally occurring mineral. This chemical process yields a highly reactive silica supplementary cementitious material (SCM) and magnesium carbonate. By replacing a portion of traditional Portland cement with Seratech’s silica, the sequestered carbon completely offsets the emissions of the remaining cement. The result is a high-performance, carbon-neutral drop-in concrete mix that requires absolutely no change to existing manufacturing infrastructure or building practices.

Description:Seratech’s technology captures CO2 directly from industrial flues and mineralizes it using naturally abundant magnesium silicate (olivine). This process yields two highly valuable products: pure silica, which acts as a supplementary cementitious material (SCM) to replace Portland cement, and magnesium carbonate, permanently locking away the carbon.

Use Cases:Low-carbon ready-mix concrete and precast elements.

Alternative To: High-carbon Ordinary Portland Cement (OPC) and toxic silica fume.

Technical Features:Produces highly reactive silica to strengthen concrete.Permanently traps CO2 in stable magnesium carbonate.Enables true carbon-neutral concrete mixes at scale.

True Carbon Neutrality: Offsets the carbon footprint of concrete by physically sequestering industrial CO2 emissions into the material itself.
Seamless Drop-in Solution: The silica SCM integrates directly into existing ready-mix concrete supply chains without requiring new equipment.
Abundant Raw Materials: Utilizes olivine, one of the most abundant minerals on Earth, ensuring global scalability.
Maintained Structural Integrity: Matches or improves the compressive strength and durability of traditional Portland cement.
Zero-Waste Process: The reaction produces highly useful byproducts (magnesium carbonate) used in other building materials like low-carbon bricks.

Verified Sustainability

Biolisty Verified LCA: By combining carbon capture with the production of a cement-replacing silica, Seratech provides a dual-action decarbonization pathway. It effectively zeroes out the carbon footprint of structural concrete.
Direct Carbon Capture. Zero Greenwashing.
Paying another company to plant trees while continuing to pour highly polluting Portland cement is greenwashing. Seratech offers verifiable decarbonization at the source. By physically capturing industrial CO2 emissions and permanently locking them into a high-performance silica SCM, Seratech transforms concrete from a massive climate liability into a functional carbon sink.
