Auris Energy will begin capturing the carbon dioxide generated during biogas production at its Mäntsälä biogas plant and supplying it for use in concrete manufacturing. Carbon dioxide deliveries will begin in early 2027.
Auris is collaborating on the project with Carbonaide and Suomen Biovoima. Concrete products made using Carbonaide’s technology will be the first commercial application for the carbon dioxide captured at Auris’s Mäntsälä plant.
“The market for biogenic carbon dioxide is developing rapidly in Finland, and biogenic carbon dioxide can also be used in industries other than construction products. We intend to replicate the carbon dioxide capture model implemented in Mäntsälä in our future biogas projects in Finland,” says Håkan Jonsson, Business Manager at Auris.
Using carbon dioxide reduces the carbon footprint of concrete by reducing the need for cement. At the same time, the captured carbon is permanently bound in the building material and removed from circulation.
Finnish innovations take carbon dioxide from Mäntsälä into concrete
Auris Energy’s Mäntsälä plant produces approximately 3,500 tonnes of biogenic carbon dioxide annually during biogas production. Suomen Biovoima will supply capture, purification and liquefaction equipment that processes the carbon dioxide into a form suitable for industrial use.
“We have been developing a carbon-negative biomethane production chain for a long time. This project is a major breakthrough in the capture and use of biogenic carbon dioxide on an industrial scale,” says Eero Tilsala, CEO of Suomen Biovoima.
Carbonaide will purchase the carbon dioxide and bind it into concrete products using its technology. Carbonaide customers Lakka Rakennustuotteet and Rakennusbetoni- ja Elementti will use the carbon dioxide captured in Mäntsälä in their products.
“This project launches Finland’s biogenic carbon dioxide market and moves our industry towards lower-carbon operations,” says Juho Hiltunen, CEO of Lakka.
“Auris’s investment gives us a strong foundation for expanding our range of products made using Carbonaide technology,” adds Teemu Teno, CEO of Rakennusbetoni- ja Elementti Oy.
Auris will begin supplying carbon dioxide to Carbonaide for use in concrete products in 2027.
