What flexbio technologie does

FlexBio Technologie GmbH is a privately held German engineering company founded in 2014 and headquartered in Einbeck, Lower Saxony. The company designs, builds and commissions modular container-based systems for anaerobic industrial wastewater treatment combined with biogas production. Its core technology converts organic industrial wastewater into biogas through anaerobic digestion, optionally followed by aerobic polishing stages with MBR technology, and includes downstream modules for gas treatment (biological desulfurization, activated carbon), gas utilization (CHP, boilers), digestate separation, flotation (DAF), sand filtration, and exhaust-air biofiltration. The modular plug-and-play container architecture is the central engineering proposition, enabling rapid installation (cited at approximately 3 months from order to commissioning) and capacity expansion as a customer's production grows.

The company serves more than 100 industrial customers across at least eight verticals: meat processing, dairy, beverage production, confectionery/sugar, fine food/convenience, chemical and pharmaceutical, bio-waste processing, and agriculture. Reference customers include Appenzeller Milchspezialitäten AG (Switzerland), Popp Feinkost GmbH, Halsbacher Qualitätsfleisch GmbH, Landbrauerei Schönram, and GRegio Energie AG. Across all installed systems, FlexBio reports 95 GWh of energy produced from wastewater and 17,733 tonnes of CO2 emissions avoided, with a typical customer payback of approximately three years and stated operating cost benefits of up to 100% reduction in wastewater disposal fees and up to 50% reduction in energy costs.

FlexBio's business model combines one-time capital equipment sales of complete treatment plants with professional services (planning/engineering, installation, commissioning, maintenance and repair billed at stated hourly rates of €90–€115 per hour) and recurring revenue optionality through financing, leasing and operator models where customers pay per unit of treated wastewater or per achieved performance. Go-to-market is direct enterprise field sales targeting industrial buyers in Germany and other DACH markets, supported by a project calculator tool on the bilingual (German/English) website for top-of-funnel lead qualification. The company is led by two managing directors, M. Eng. Waldemar Ganagin and M. Sc. Paul Bauer, has no disclosed institutional shareholders or external funding, and is not publicly listed.

Core offering

FlexBio Technologie GmbH designs, manufactures and commissions modular container-based anaerobic wastewater treatment plants and compact biogas plants for industrial customers. Its systems convert high-strength organic industrial wastewater and organic residues into biogas for on-site energy generation, integrating mechanical pretreatment, anaerobic digestion, gas treatment and optional aerobic post-treatment (MBR/SBR) in pre-fabricated plug-and-play containers. The company also delivers installation, commissioning, maintenance and operator/financing services, serving meat processing, dairy, beverage, confectionery, fine food, chemical/pharmaceutical, bio-waste and agricultural operators.

Product overview

FlexBio Technologie GmbH is a system provider offering modular, container-based industrial wastewater treatment and biogas plants. The product portfolio centers on three core offerings: (1) Biogastechnik for biogas production from organic substrates and waste, (2) Anaerobe Abwasserreinigung for high-strength industrial wastewater treatment with energy recovery, and (3) Kompaktkläranlage combining anaerobic and aerobic stages with MBR technology for complete wastewater treatment. Supporting these core systems are add-on modules including Gasaufbereitung for biogas upgrading to biomethane, Gasverwertung for CHP/boiler utilization, Feststoffabscheider for digestate separation, Flotation (DAF) for suspended solids removal, Filtration for process water polishing, and Abluftfilter for exhaust air treatment. The company also provides a cloud-based online monitoring and real-time control system for fully automated plant operation. Systems are designed on a modular plug-and-play principle, allowing flexible capacity expansion. FlexBio serves industries including meat processing, dairy, beverages, confectionery, fine foods, chemical/pharmaceutical, bio-waste treatment, and agriculture.
