What OKOBIT does
OEKOBIT GmbH is a German manufacturer and general contractor of biogas and biomethane plants, headquartered in Föhren, Germany, and privately held by its three managing directors (Christoph Spurk, Sebastian Schmidt, Michael Marx). The company was founded in 2000 and operates as a full-service provider covering consulting, planning, turnkey plant construction, and post-commissioning operation and maintenance — the latter delivered through its wholly owned subsidiary greentec-service GmbH and other group entities (gt energie service GmbH, ÖKOConsult Umwelttechnik GmbH, ConZept-Containermanufaktur GmbH). Its core products are substrate-flexible biogas and biomethane plants, including the FarMethan product line for agricultural operations (75 kW, 99 kW, 150 kW, and above) and the HoMethan compact plant for small farms and emerging markets.
Technically, OEKOBIT develops in-house proprietary components covering the full biogas production chain: prefabricated concrete/steel tanks, agitators, stainless-steel wall-mounted heating systems, double-membrane gas storage with meshed synthetic woven desulfurization, rugged substrate dosing and pumping systems, gas upgrading to biomethane grid quality, and a proprietary Process Control System (PCS) for efficiency and power-consumption optimization. It claims experience with more than 85 different substrates and is DVGW-certified under G 493-1 (March 2026) for biomethane production, with plants historically audited by TÜV. Reference installations include the Stadtwerke Boppard biomethane plant (up to 1,400 Nm³/h biomethane), the Willingshausen plant (9.1 million Nm³/year biogas; 3.5 million Nm³/year biomethane; 13,200 t/year CO₂ savings), the SAS Gentillerie Méthanisation plant in Neuflize, France (2022), and the Farmethan Hallert plant for the Fiedler family.
OEKOBIT generates revenue through project-based turnkey plant construction contracts (one-time license-equivalent), professional consulting services (pre-design study, feasibility study, basic analysis, perspective consulting), and managed plant operation/maintenance services via its service subsidiary. It sells through direct enterprise field sales with on-site consultations and site visits, targeting agricultural operations, energy suppliers, municipal utilities, and investors, with no resellers or distributor channel. Sales motion is sales-led and project-quoted, with no publicly disclosed pricing. The company has cumulatively delivered over 250 national and international projects, primarily in Germany and France, and has not raised any external funding rounds.
