Vateris GypCarb CO2-Derived Vaterite Concrete Additive

Vateris is a UK-based CO2-to-materials company founded in 2021 as Concrete4Change by Prof. Sid Pourfalah (CEO) and Dalraj Nijjar (COO), and renamed in 2026. It tackles both industrial CO2 emissions and the carbon footprint of cement by turning flue gas and calcium-rich waste into materials that cut cement content in concrete.

Its plug-in carbon capture and utilisation process takes raw industrial flue gas without purification and reacts the CO2 with calcium from gypsum to form vaterite-based calcium carbonate. The main product, GypCarb, is an engineered mineral additive for cement and concrete that raises performance, reduces cement content and lowers embodied carbon, while the leftover sulfate is turned into high-purity SOP potassium sulfate fertiliser. A pilot plant has been commissioned and the company is scaling toward a commercial plant co-located on an industrial partner's site, serving cement, precast and ready-mix producers.

• Raw flue gas capture: plug-in CCU process works with existing industrial CO2 sources without gas purification.
• Gypsum-based mineralisation: CO2 reacts with calcium from gypsum to form vaterite calcium carbonate.
• GypCarb additive: engineered vaterite mineral for cement and concrete that reduces cement content.
• SOP fertiliser co-product: leftover sulfate becomes high-purity potassium sulfate for agriculture.
• Industrial trials: validated in real concrete mixes with Heidelberg Materials UK, Cemex and Panthera in 2025.
• Co-located plants: commercial units designed to sit on an industrial partner's site.

Vietnamese fertiliser and chemical plants with phosphogypsum stockpiles could co-locate a unit to convert waste gypsum and CO2 into GypCarb and SOP fertiliser. Cement groups can trial GypCarb to reduce clinker use in blended cements. Coal or gas power plants can explore a partnership to monetise flue gas CO2.

GypCarb lets producers reduce cement content and embodied carbon while improving concrete performance, using a material that fits existing cement and concrete production. CO2 is captured directly from raw flue gas without costly purification, and is locked permanently in mineral form. Gypsum waste becomes a feedstock, and the SOP fertiliser co-product adds a second revenue stream to each plant.

Cement makers and heavy emitters are seeking carbon capture routes that produce saleable products rather than storage costs, and concrete producers want additives that lower cement content without performance trade-offs. Southeast Asia generates large volumes of flue gas and gypsum by-products from power, fertiliser and chemical plants, creating feedstock for CO2-to-materials models.

Founded in 2021 as Concrete4Change in the UK; renamed Vateris in April 2026, when Holcim MaQer Ventures and Kiilto Ventures joined existing investors Goldbeck and Zacua Ventures, bringing total capital raised to USD 10 million. Recognised with a Horizon Europe Seal of Excellence. Case studies with Holcim, Goldbeck, Heidelberg Materials, Cemex, Panthera and Marshalls.
