What EnviTec Biogas does

EnviTec Biogas AG, founded in 2002 in Lohne, Germany, and listed on the Frankfurt Stock Exchange (ETG) since July 2007, is one of Germany's largest vertically integrated biogas producers. The company covers the full biogas value chain across four interlocking businesses: (i) Anlagenbau — turnkey design, engineering, and construction of biogas and biomethane plants for agricultural, industrial, and utility customers globally; (ii) Eigenbetrieb — operation of 91 own biogas plants in Germany, producing biogas, biomethane, Bio-LNG, and food-grade liquid CO2; (iii) Service — biological and technical maintenance, cybersecurity, grid protection testing, repowering, and sustainability certification; and (iv) Energievermarktung — marketing of produced biogas, biomethane, electricity, and renewable energy certificates. The company's installed base exceeds 577 MW across 18 countries with more than 700 completed projects, and it employs approximately 699 people worldwide.

Technology is anchored by the proprietary EnviThan gas upgrading system, which has been deployed in 100+ plants globally to convert raw biogas into grid-quality biomethane, and the EnviCO2 liquefaction system, which recovers food-grade CO2 as a co-product. EnviTec has also become Germany's largest integrated Bio-LNG producer through its BioEnergie Park Güstrow facility and, via the January 2025 acquisition of LIQVIS GmbH from Uniper, now operates 18 LNG/CNG refueling stations in Germany and France. The product portfolio was broadened in March 2025 with the EnviTec Wind|Solar GmbH & Co. KG joint venture to develop PV and wind projects, complementing the core biogas franchise.

Commercial mechanics combine project-based one-time EPC revenue for plant construction (order backlog EUR 148.1M as of FY2025, of which EUR 117.1M international) with recurring service fees from biological/technical contracts and recurring revenue from own-plant operations and energy marketing. FY2025 revenue totaled EUR 312.6M (down 7.4% from EUR 337.7M in 2024 and off the EUR 445.8M 2023 peak), while EBT was EUR 26.0M versus EUR 44.0M in 2024 and EUR 88.2M at the 2023 peak. Named enterprise customers include SJI Renewable Energy Ventures (US, 15-project pipeline), Gasum (Nordic EnviThan deployments), PowerCo SE (10-year solar PPA), TT-Line (maritime Bio-LNG bunkering), and Byont (Belgian upgrading/CO2 liquefaction). Ownership is moderately concentrated, with TS Holding GmbH (25.9%), 2. vLB GmbH & Co. KG (22.6%), and OvL Verwaltungs GmbH (15.0%) as the largest shareholders.
