Carbonaide expands its CO₂ partner network as Auris Energia launches biogenic carbon dioxide capture at its Mäntsälä biogas plant. Starting in 2027, captured CO₂ will be delivered into concrete production, where Carbonaide’s technology enables permanent storage and cement savings through carbon dioxide curing.
The project connects carbon capture directly to the built environment. Biogenic CO₂ generated during biogas production is captured, purified, and liquefied with technology provided by Suomen Biovoima, after which Carbonaide utilizes and stores the carbon dioxide through CO₂ mineralization in concrete production in its client locations.
“We are proud that our strong customer traction finally materializes biogenic carbon dioxide capturing in Finland. For that we can thank both our clients and Auris. This collaboration with Auris also improves further scaling of our solution in Finland”, says Jonne Hirvonen, COO of Carbonaide.
Finnish Concrete Producers Lead the Way
Concrete manufacturers Lakka and Rakennusbetoni‑ ja Elementti are among the first Carbonaide clients to use Mäntsälä‑originated biogenic CO₂ in their products. Through Carbonaide’s CO₂ curing system, the captured carbon dioxide is mineralized into stable carbonates and locked permanently into concrete.
“This project initiates Finland’s biogenic carbon dioxide market and moves our industry toward lower emissions,” says Juho Hiltunen, CEO of Lakan Betoni.
“It is encouraging to see domestic players developing the biogenic carbon dioxide market. Auris’s investment provides a strong foundation for expanding the range of products produced with Carbonaide technology and for accelerating the industry’s shift toward lower emissions.”, Teemu Teno, CEO of Rakennusbetoni- ja Elementti.
The result is cheaper, faster, stronger and greener low carbon concrete without changes to existing production lines.
From Capture to Materialized Impact
Auris Energia’s Mäntsälä facility produces approximately 3,500 tonnes of biogenic CO₂ annually. By integrating carbon capture with Carbonaide’s one‑stop solution, the carbon dioxide is no longer a by‑product but a raw material for concrete decarbonisation.
“Biogenic carbon dioxide opens new opportunities for many industries. The solution we are implementing is based on Finnish expertise,” says Håkan Jonsson, Business Development Manager at Auris Energia.
Carbon capture alone is not enough. Carbonaide ensures that captured CO₂ is permanently stored through an industrial mineralization process inside concrete products. By connecting capture sites, concrete producers, and carbon management into one scalable system, we enable negative emissions where materials are actually produced and used.
About Carbonaide
Carbonaide makes carbon-negative concrete economically viable. With the Carbonaide CO₂ solution, concrete manufacturers can utilise carbon dioxide to improve their products and store carbon permanently.
