EnviTec Biogas has switched on a new biomethane facility in Slovakia. This marks a significant step in the country’s push toward cleaner energy—and the company’s second completed project there.
The newly commissioned EnviThan gas upgrading plant, with a capacity of 417 Nm³/h, is now feeding into the grid from the municipality of Ožďany.
“Our customer, CITA VIA s.r.o., is upgrading 750 Nm³/h of biogas to biomethane with the plant in the municipality of Ožďany. In the future, the company intends to increase production in the long term to a maximum of 1,300 Nm³/h of biogas,” explains Stefan Laumann, Head of Gas Upgrading at EnviTec Biogas.
The project builds on an existing biogas plant that has been running for 14 years, powered by maize, cattle straw dung and chicken dung. With the addition of the new upgrading unit, electricity generation will continue—while opening a new chapter in renewable gas production.
“This is now complemented by the production of advanced biomethane from cattle straw and chicken manure,” says Miroslav Kováčik, Head of EnviTec Service in the Czech Republic. “In the long term, however, we will switch to using waste materials only, allowing us to support the green energy transition in Slovakia even more effectively,” says Ing. Viktor Hegedüs, Managing Director of CITA VIA.
Behind the rollout is a focus on speed and reliability. The membrane-based EnviThan system was fully tested before delivery, streamlining installation and cutting downtime.
“Our Factory Acceptance Test, or FAT for short, ensures rapid and efficient commissioning on site and thus saves valuable time and resources,” says Laumann. Ongoing support will be handled nearby by EnviTec’s Czech service arm, ensuring fast response times for maintenance and future upgrades.
The launch comes as Slovakia accelerates its shift toward renewable energy. Backed by €103 million from the EU Recovery Fund, the country is investing heavily in green infrastructure, with biomethane expected to play a central role. Analysts estimate that 34 existing biogas plants could be converted for biomethane production.
Momentum is also building across the border. The Czech Republic is positioning biomethane as a viable alternative to natural gas, targeting major cuts in heating emissions. Industry figures suggest waste-based biomethane production could reach 700 million cubic meters annually, with plans for around 100 plants by 2035.
Together, the developments signal a growing regional push to turn agricultural and organic waste into a cornerstone of Europe’s low-carbon energy future.
