- 417 Nm³/h EnviThan unit upgrades 750 Nm³/h biogas to biomethane, with plans to scale production to 1,300 Nm³/h.
- Current feedstock: maize and cattle/poultry manure, with a planned shift to waste materials for biomethane.
- €103 million from the EU Recovery and Resilience Facility is available for new renewable energy plants in Slovakia, with identified potential in 34 biogas plants.
- Czech estimates put biomethane-from-waste potential at 700 million m³/year and target roughly 100 plants by 2035.
Project overview
EnviTec Biogas commissioned a 417 Nm³/h EnviThan gas upgrading unit in Ožďany, Slovakia, enabling grid injection of biomethane and representing its second biomethane project in the country; the customer CITA VIA operates an adjacent biogas plant feeding 750 Nm³/h into upgrading with plans to scale biogas input to 1,300 Nm³/h.
Feedstock and operations
The existing agri-biogas plant has operated for 14 years using maize and cattle and poultry manure; electricity generation continues while upgraded biomethane is produced, and the operator plans a long-term shift to waste-derived feedstock to increase sustainability.
Technology and commissioning
The EnviThan unit uses membrane separation and was produced at Saerbeck; it underwent a Factory Acceptance Test in the customer's presence to speed on-site commissioning, with regional service support available from the nearby Czech subsidiary.
Market context
Slovakia is expanding renewables with €103 million in EU Recovery and Resilience Facility funds available for new renewable plants and analysis identifies potential for biomethane at 34 biogas sites; Czech estimates put waste-based biomethane potential at about 700 million m³/year, targeting roughly 100 plants by 2035.
