Valmet has received an order from Suomen Biovoima Oy to deliver a Valmet DNAe Distributed Control System (DCS) for a CO₂ liquefaction plant at Auris Energia’s biogas plant in Mäntsälä, Finland. It will be the first CO₂ liquefaction plant of its kind built in Finland with this technology.

Valmet will deliver a Valmet DNAe Distributed Control System to Suomen Biovoima Oy for a CO₂ liquefaction plant being built at Auris Energia’s biogas facility in Mäntsälä, Finland.
The project marks a concrete step forward in the green transition, enabling carbon capture and utilization directly at a biogas plant. At Auris Energia’s plant, CO₂ is generated as a byproduct of biogas production. Instead of releasing CO₂ into the atmosphere, Suomen Biovoima’s technology will capture, purify, and liquefy it for reuse in industrial applications such as concrete production, where the CO₂ is permanently bound into the building materials. By turning emissions into valuable raw material, the solution supports the circular economy and helps reduce the carbon footprint of energy production.
“This project is an important step for us in developing more advanced and sustainable biogas and biomethane solutions. By capturing and utilizing CO₂, we can turn emissions into a valuable product while improving overall efficiency. Collaboration with Valmet allows us to bring modern automation into our solutions and scale these innovations in future projects," says Mikko Bengts, Sales Manager at Suomen Biovoima Oy.
Unlocking resource efficiency through automation
Valmet's automation solution helps Suomen Biovoima and plant owner and operator Auris Energia to strengthen resource efficiency, bringing one of the cornerstones of Valmet's strategy to life at the customer site.
With advanced process control and real-time visibility, the Valmet DNAe system enables more efficient use of energy, raw materials, and human resources. Automated controls reduce the need for manual intervention, and a high level of security enables unmanned operations of the plant.
The system also improves reporting and transparency, helping operators optimize performance and ensure consistent product quality.
“In this project, we provide a cybersecure, modern, and robust Valmet DNAe system, while Suomen Biovoima brings their unique process know-how. Together, we create real added value to Auris Energia’s biogas plant. This solution will enable secure data transfer, monitoring, and reporting of the plant status and KPIs to Auris Energia. We look forward to developing this concept together with Suomen Biovoima. This project is a great example of how automation can support both sustainability and business performance,” says Matti Miinalainen, Senior Sales Manager, Automation business area, Valmet.
Long-term value through lifecycle thinking
The solution is designed with a long lifecycle in mind. Valmet supports customers beyond the initial delivery with continuous services, system development, and upgrades, keeping the plant efficient and competitive over time.
This lifecycle approach helps customers adapt to changing requirements, improve performance continuously, and maximize the return on their investment.
The delivery will take place in phases, with the main system delivery scheduled for November 2026. Installation is planned for December 2026, and start-up is expected in the first quarter of 2027. The order is included in Valmet’s orders received during the second quarter of 2026. The value of the order will not be disclosed.
