What Biogest does

Biogest (legally BIOQUADRAT Energie- und Wassertechnik Holding GmbH) is a Vienna-based, privately held engineering, procurement, and construction (EPC) firm that designs and delivers biogas and biomethane plants, founded in 1989 and active in the renewable energy sector since 1999-2000. The company has completed 200+ projects across 20+ countries, operating through nine wholly-owned subsidiaries (BIOGEST France, BIOGEST America Inc., BIOGEST UK Ltd, BIOGEST Italia, BIOGEST Energie a Vodni Technologie in Czech Republic, BIOGEST SRL Romania, BIOGEST Asia Pacific PTY LTD, SMART BIOSERVICES Serbia, plus the BIOP OPO brand in Italy). Its technology portfolio centers on five proprietary anaerobic digestion platforms — PowerRing, PowerSPF, PowerCompact, PowerDigest, and PowerTower — each engineered for specific feedstock and capacity profiles, with PowerRing as the flagship for variable fibrous agricultural substrates.

Biogest generates revenue through a vertically integrated six-step service model: project development and feasibility, design engineering, co-investment, turnkey construction, technical and biological services, and long-term operation and maintenance. The company derives EPC revenue from one-off plant builds, recurring revenue from service contracts and the bioservice App for remote monitoring, and equity-backed returns through its BIOP Own Plant Operation (OPO) platform where it co-invests in and directly operates plants. Customer segments are agricultural operations (farms, cooperatives, dairy/livestock producers) as the primary vertical, and municipal/industrial organic waste generators as the secondary vertical. Primary geographies are Europe (Austria, France, Germany, UK, Italy, Czech Republic, Romania, Serbia, Croatia, Greece, Turkey, Ukraine, Hungary, Poland, Ireland), North America (US, Canada), and APAC (Australia, New Zealand, India, South Korea, Thailand, Malaysia), with 35+ countries covered by dedicated country-level sales managers and additional license partners.

The company is led by CEO Martin Schlerka (since 1999), COO Martin Hornhuber (since 2015), and CFO Andreea Liubimirescu, with a recent addition of David Prat as Head of Investments in September 2026. Ownership includes a 40% stake held by an Austrian private foundation in the OPO business since 2010 and Eiffel Investment Group as a minority shareholder with a quasi-equity facility since 2022. The company is privately held, does not publicly disclose revenue, and reports 51-100 employees (though internal sources cite 100+ with staff from 20+ countries).

• Anaergia: Canadian organics-to-energy platform with AD and RNG solutions for municipal and agricultural waste; competes with BIOGEST on multi-feedstock AD plant construction and on North American RNG opportunities.
• Xergi (Nature Energy): Danish AD specialist with EPC plus large-scale own plant operation across Northern Europe; Xergi's EPC model and agricultural/manure focus map closely to BIOGEST's, while the Nature Energy platform adds a large OPO benchmark.
• Agraferm Technologies: German AD plant manufacturer offering engineering, construction, and service for agricultural and industrial biogas/biomethane plants; directly comparable product portfolio and target customer segments to BIOGEST.
• Weltec Biopower: German-based turnkey biogas and biomethane plant manufacturer with agricultural and waste feedstocks and an own-plant operation arm; competes head-to-head with BIOGEST on European AD EPC tenders and on technology for fibrous/manure-based substrates.
• Zorg Biogas: Italian AD plant EPC and technology provider focused on agricultural and agro-industrial biomethane projects; comparable to BIOGEST's Italian subsidiary footprint and to its flagship agricultural PowerRing-type offerings.
• EnviTec Biogas AG: Listed German AD plant constructor and operator with EPC plus own-plant operation; closest publicly comparable to BIOGEST given the combined EPC + O&M + plant ownership model and similar agricultural feedstock focus.

Broad incumbents

• Veolia: Global environmental services and energy group with significant biogas/biomethane operations integrated into its waste and energy divisions; broad overlap with BIOGEST in feedstock supply, plant operation and biomethane offtake, but at much larger scale and as part of a wider portfolio.
• Hitachi Zosen Inova: Large Swiss-Japanese EPC incumbent with significant AD/biogas and waste-to-energy capabilities including Kairos and other industrial-scale technologies; overlaps with BIOGEST on large biomethane and biogas projects but at a meaningfully larger scale and broader portfolio.
• Engie: French multinational utility developing biomethane injection and biogas-to-power assets across Europe; competes indirectly with BIOGEST for French agricultural biomethane projects, while also being a potential off-taker/partner for BIOGEST-built plants.
