The company operates two established waste anaerobic digestion plants with a combined electrical output of 2,537 kWel and an existing biogas processing capacity of 350 Nm³/h. Both sites have been in operation for more than 15 years and are certified as specialized waste management facilities in accordance with Section 56 of the German Waste Management Act (KrWG). Well-established reception, unpacking, and sanitization processes form the basis for well-established and reliably organized plant operations.

Zum Verkauf steht eine etablierte Biomethananlage mit einer installierten elektrischen Leistung von 1.336 kWel sowie einer Biogasaufbereitungsanlage (BGAA) mit 350 Nm³/h Einspeisekapazität. Die Anlage ist seit 2011/12 in Betrieb, wurde regelmäßig gewartet und befindet sich in einem hochwertigen technischen Zustand; nach Übernahme durch den heutigen Eigentümer wurden rund 4,3 Mio. € in die Sanierung investiert, sodass kein wesentlicher Investitionsstau besteht und weitere größere CapEx-Maßnahmen derzeit nicht geplant sind. Ergänzt wird der Standort durch eine Freiflächen-PV-Anlage mit 290 kWpeak. Die flexible Fahrweise erlaubt die gezielte Steuerung zwischen EEG-vergüteter Verstromung und Biomethanproduktion aus NawaRo und Wirtschaftsdünger; die Biomethanproduktion lag zuletzt zwischen 24 und 30 GWh pro Jahr, 2025 war die Anlage nahezu vollständig ausgelastet. Die EEG-Vergütung ist bis Ende 2031 gesichert, Offtakes sowie Genehmigungs- und Umweltunterlagen liegen vollständig vor. Für die Weiterentwicklung besteht ein klar definierter Wertsteigerungspfad: Durch Erhöhung des Wirtschaftsdüngeranteils im Substratmix ohne Mengenerhöhung lässt sich die Wirtschaftlichkeit steigern; nach Auslauf der EEG-Vergütung ab 2032 ist der Übergang der BHKW in das Ausschreibungsregime vorgesehen. Damit ergibt sich ein stabiles Betriebsfundament mit klaren Optimierungsoptionen für den Erwerber.

This long-established company operates a biogas plant for the combined generation of electricity and heat. The heat is used to meet the basic heating needs of a public health facility, while the electricity generated is fed into the public grid through direct sales.

The company up for sale comprises four biogas plants at three locations with a combined electrical output of 3,380 kWel. The plants, which have been in operation since 2012/2013, are regularly maintained and are in good technical condition. With a processing capacity of over 80,000 metric tons of substrate per year, the company has a solid operational foundation in the region.

An established biogas plant in Lower Saxony with an installed electrical capacity of 530 kWel is for sale. The remaining term of the EEG extends through the end of 2026; continued operation through participation in the EEG tender is planned, and a corresponding basis for decision-making is available. The plant is in good technical condition and has been carefully maintained. The substrate supply is secured regionally: A significant portion of the required feedstock is sourced directly from local farmers. The long-term utilization of the digestate is ensured through sufficient available agricultural land. The investment offers a buyer an established operational base with clear prospects for continued operation through participation in the tender process, as well as a low level of operational complexity.

A portfolio of three existing biogas/biomethane facilities, plus a greenfield project in northern Germany, is for sale. The portfolio has a combined electrical capacity of over 4,580 kWel and a biomethane processing capacity of 700 Nm³/h. The facilities are in excellent technical and operational condition. Thanks to ongoing investments in refurbishment and expansion, there is no discernible investment backlog. Operations are on a stable footing: The substrate supply is secured regionally and, with farm manure accounting for over 50% of the feedstock, offers an attractive, GHG-efficient feedstock base. The site is operationally secure; management remains available to ensure an orderly transition phase. There are clearly defined paths for value creation going forward. In addition to ensuring continued operations, concrete expansion plans focused on biomethane have been developed. Furthermore, additional development concepts are in place, including plans for heat utilization, land development, and collaborations and partnerships. In addition to the planned biogas processing, partial power generation and the production of liquid CO₂ are also planned. Combined with the greenfield project, this creates a scalable foundation for growth with multiple options for the acquirer.

The company has been operating a biogas plant in the Rhineland (North Rhine-Westphalia) for over 15 years, which is licensed in accordance with environmental protection regulations. The plant features two combined heat and power units with an installed electrical capacity of approximately 0.75 MWel and is well-maintained from a technical standpoint. Replaced catalysts, an existing full-service maintenance contract, and expert inspections with no findings underscore its sound technical condition. A positive decision regarding connection to the gas grid also provides an attractive foundation for potential future development toward biomethane.

The company positions itself as a pioneer in the circular economy and environmental technology, offering specialized solutions in the field of recycling plants. It has made a name for itself by developing a patented separation system that achieves efficient results—particularly with “hard-to-recycle” materials—while recovering cellulose fibers with a high yield. Key features include energy savings of up to 50 percent during operation and an environmentally friendly process that does not use hot water or chemicals, enabling the company to ensure high resource efficiency. With a projected project volume of 13 million euros in revenue and 2 million euros in EBT by 2025, the company underscores its economic viability and its potential for sustainable growth.
