EnviTec Biogas delivers gas upgrading plant to Lithuanian dairy farm

EnviTec Biogas is supplying a biogas plant and gas upgrading facility to Citrone, a dairy farm and processing plant in Lithuania's Šakiai district, as part of the country's push towards renewable energy.
The project, which is supported by state funding, includes EnviThan membrane technology for gas upgrading with a capacity of 675 Nm³/h of biomethane (6.29 MW).
The plant will convert cattle manure and slurry into biomethane for export and potential use in the fuel market.
"Our customer is relying on the comprehensive expertise of our EnviTec Biogas team and EnviThan membrane technology for the construction of the gas upgrading plant," said Egidijus Semeta, service manager at EnviTec Biogas Service Baltic SIA, based in Riga.
The gas upgrading plant, currently in production at EnviTec's Saerbeck site, is scheduled for delivery before 30 April 2026 in accordance with funding guidelines.
Following installation and commissioning, the facility will feed biomethane into the local high-pressure gas pipeline.
"Such investments are an important step for the Baltic region in reducing its use of fossil fuels," Semeta added.
Lithuania, Estonia and Latvia have been independent of gas imports since 2022 and are now focusing on decarbonisation across other sectors.
Lithuania's Ministry of Transport signed a joint declaration with Germany and Japan in 2024 to promote the development and use of e-fuels with near-zero CO₂ emissions.
EnviTec Biogas, which operates from Lohne and Saerbeck, has been active in the Baltic market for more than 15 years.
"Between 2009 and 2013 alone, we built seven plants in Latvia, and four additional gas upgrading projects have been added in Estonia since 2019," said Stefan Laumann, head of gas upgrading at EnviTec Biogas.
