What Seratech does

Seratech Ltd is a London-based climate-technology company founded in July 2021 by researchers from Imperial College London. It has developed Seratech Cement, a drop-in replacement for Portland cement made from naturally abundant olivine (a magnesium silicate mineral) and captured CO2. The company's patent-pending process permanently sequesters CO2 within the mineral matrix, with the carbon stored in the resulting concrete product. Seratech targets block manufacturers and construction industry partners in the United Kingdom and Europe, selling the cement material directly as a B2B replacement for Portland cement.

Seratech's core technology centres on carbon mineralisation: CO2 sourced from Direct Air Capture (DAC) or industrial emissions is reacted with olivine to form stable mineral carbonates, which are then used as the binder in concrete blocks. This approach is positioned as lower-energy than alternative carbon capture pathways because it eliminates the need for CO2 liquification, transport, and geological storage. The company claims its product cuts embodied carbon by over 95% versus traditional Portland-cement concrete blocks and is priced 20% cheaper than Portland cement, while meeting UK and European performance standards for concrete blocks.

Seratech operates as a materials supplier with an enterprise field-sales motion, targeting block manufacturers as its primary customer segment and the broader construction industry as a secondary segment. Revenue, customer counts, and funding rounds are not publicly disclosed; the only capital inflows referenced are two grants obtained through The Greenhouse climate-tech accelerator (co-founded by The Centre for Climate Change Innovation and The Royal Institution) that funded the hiring of three additional researchers. The company employs 1-10 people and holds a patent-pending process for its mineralisation technology.

Core offering

Seratech develops and sells Seratech Cement, a drop-in replacement for Portland cement made from naturally abundant olivine (magnesium silicate) and captured CO2. The patent-pending carbon mineralisation process permanently sequesters CO2 within magnesium silicate rocks during concrete block production, eliminating the need for CO2 liquification, transport, and geological storage. The product is sold directly to block manufacturers and delivers over 95% embodied carbon reduction at a 20% lower cost than Portland cement.

Product overview

Seratech offers a single unified product: Seratech Cement. This cement replacement material is made from olivine (a magnesium silicate mineral) and captured CO₂, and serves as a direct drop-in replacement for Portland cement in concrete products including blocks. The product eliminates the need for carbon-intensive Portland cement in concrete manufacturing, enabling net zero construction materials at scale.

• The Greenhouse AcceleratorcoreStrategic or Co-development Partner · 1 August 2021The Greenhouse is a climate-tech accelerator founded by The Centre for Climate Change Innovation and The Royal Institution. In August 2021, Seratech was accepted into this accelerator and has since received two grants to hire three further researchers.
• Imperial College LondoncoreStrategic or Co-development PartnerSeratech was established by staff and researchers based at Imperial College London in July 2021, with technology in development since late 2020. Key team members including Sam Draper, Barney Shanks, Prof Chris Cheeseman, and Prof Hong Wong are affiliated with the university.

Scale indicators4 records

Recent moves5 records

Expansion highlights4 records

Direct peers

• CarbonCure Technologies: CarbonCure injects captured CO2 into ready-mix concrete and has expanded into carbonated concrete blocks using mineralization chemistry. It is the most directly comparable company to Seratech in terms of using CO2 mineralization to displace Portland cement content in concrete products.
• Solidia Technologies: Solidia uses CO2 curing and mineralisation to produce lower-carbon concrete and pre-cast products, sharing Seratech's core thesis that CO2 can be a feedstock rather than a waste stream in cement and concrete manufacturing.
• Carbon8 Systems: Carbon8 Systems commercialises accelerated carbonation technology that mineralises CO2 into aggregates used in concrete blocks, directly competing with Seratech's approach of mineralising CO2 into a cementitious binder for the same block-manufacturer customer segment.
• Sublime Systems: Sublime Systems produces low-carbon cement via an electrochemical process that does not rely on traditional limestone calcination, directly competing with Seratech Cement as a drop-in alternative to Portland cement for concrete manufacturers.
• Fortera (formerly Brimstone): Fortera (formerly Brimstone) produces carbon-negative Portland cement using a mineralisation route that captures CO2 during the cement-making process, targeting the same block and ready-mix concrete end-markets as Seratech.
• Carbon Upcycling Technologies: Carbon Upcycling Technologies uses CO2 mineralisation to produce supplementary cementitious materials and fillers that partially replace Portland cement, mirroring Seratech's drop-in replacement thesis for the concrete supply chain.
• Blue Planet Systems: Blue Planet Systems produces carbon-negative aggregate through mineralisation of captured CO2 for use in concrete, operating in the same CO2-to-cementitious-material technical and customer space as Seratech.

Broad incumbents

• Holcim: Holcim is one of the world's largest cement and aggregate incumbents and is actively commercialising lower-carbon cements (e.g., its ECOPact and TectorAID ranges), making it a broad incumbent competing for the same block and construction-industry customers.
• Heidelberg Materials: Heidelberg Materials is a global cement incumbent with major low-carbon and CCUS initiatives (e.g., evoBuild, geocycle), representing the established competition Seratech faces in supplying European block manufacturers and construction projects.

Emerging players

• Calix: Calix develops CO2 capture and mineralisation technology applied to cement and lime manufacturing, making it an adjacent emerging player whose mineralisation approach overlaps with Seratech's CO2-to-cementitious-binder thesis.
