EnviTec Biogas has commenced construction on its flagship project in Sweden. The milestone was marked by a groundbreaking ceremony in Vara, Västra Götaland. The flagship biogas plant is being developed by Biogas Västra Skaraborg (BVS) in partnership with EnviTec Plant Construction and is set to become a major hub for biomethane and bio-LNG production in Scandinavia. Sweden also started operations in Gasum’s earlier this year.
EnviTec Biogas Flagship Plant, Sweden: Project Factsheet
Location: Vara, Västra Götaland, Sweden
Developer: Biogas Västra Skaraborg AB (BVS)
EPC/Technology Partner: EnviTec Biogas Plant Construction
Number of Digesters: Five
Technology: EnviThan gas upgrading. Nordsol Flash-2-Sweep liquefaction
Capacity: 70 GWh biomethane annually
Feedstock: 370,000 tonnes annually from farm manure and agricultural residues
Special Features:
- Hygienization process at 52 degrees Celsius for 10 hours
- Advanced heat integration for energy efficiency
Financial Subsidy: Supported by Sweden’s Klimatklivet program
End Use: Bio-LNG for transport, maritime, and industrial sectors
What to Expect
Once operational, EnviTec’s flagship biogas project in Sweden will process 370,000 tonnes of feedstock annually. This will primarily be from farm animal manure alongside agricultural residue.
At full capacity, it is expected to generate around 70 GWh of biomethane per year, making it one of the largest biogas initiatives in Sweden.
EnviTec Biogas Flagship Plant, Sweden: Project Timeline
2023–2024: Planning and permitting phase. Klimatklivet funding also secured
Q3 2025: Groundbreaking ceremony held in Vara, Sweden
Q3 2025–2026: Construction and installation of digesters, upgrading, and liquefaction equipment
2027: Commissioning and start of biomethane and bio-LNG production
Design Concept
The project’s design features five digesters with separate feed systems, enabling custom retention times for different inputs. The plant will also incorporate advanced heat integration, with exchangers and industrial heat pumps preheating fresh slurry and cooling digestate. To meet hygiene standards, digestate will also undergo isolation at temperatures above 52 degrees Celsius for at least ten hours.
Gas upgrading will be delivered through EnviTec’s proprietary EnviThan technology. The technology is able to achieve methane concentrations of up to 98%. Meanwhile, Dutch partner Nordsol will also deploy its Flash-2-Sweep process to liquefy the biomethane. This allows for use in transport, shipping, and industries as bio-LNG.
Sweden’s Klimatklivet Investment Program
Supported by Sweden’s Klimatklivet investment program, EnviTec’s flagship biogas project in Sweden aims to achieve measurable emissions reductions while also strengthening local rural economies. By expanding local biomethane infrastructure, the flagship biogas project by Envitec also supports Sweden’s broader climate goals and energy transition strategy.
Envitec’s Spiderweb
For EnviTec Biogas, this project continues to enhance its market share in Northern Europe. Regionally, EnviTec is also leveraging expertise from its German, French, and Italian operations to deliver this Swedish plant.
In Germany, the company already operates multiple biomethane plants with grid injection capabilities, while in France it has focused on medium-scale facilities tied to farming cooperatives.
Unlike those, the Vara plant prioritizes bio-LNG exports for transport and places Sweden among Europe’s frontrunners in renewable gas innovation. This project also complements EnviTec’s wider European growth plan, where demand for bio-LNG is accelerating under the EU’s decarbonization framework.
