What Doranova does

Doranova Oy is a Finnish environmental technology company founded in 1995 and headquartered in Vesilahti, Finland, that designs and builds turnkey (KVR) biogas plants using three proprietary, feedstock-specific digestion concepts: Wetferm for slurries and biowaste co-digestion, Solidferm for high-solids clean feedstocks up to 25% dry matter, and Hardferm for the most challenging substrates containing sand, stones, and other impurities (Hardferm received patent protection in December 2019 and was first deployed commercially in Jepua in June 2020). Beyond the three core plant concepts, the company delivers landfill gas collection and utilization systems, preparatory studies, permitting, technical design, and project management services.

The business model is project-based EPC: Doranova acts as technology supplier and KVR-urakoitsija (turnkey contractor) handling design, construction, and commissioning for each plant, with revenue recognized on project delivery and additional professional services revenue from feasibility, licensing, and design work. Customer segments are primarily Finnish agricultural operations (pig and cattle farms, agricultural cooperatives), food-processing companies (potato, sauce/broth, slaughterhouse by-products), energy utilities and municipalities, and research institutions such as Luonnonvarakeskus (Natural Resources Institute Finland). Select customers include Jepuan Biokaasu, Biokymppi, Pielisen Bio, One1/Pohjolan Peruna, Nevel/Puljonki, Viskaalin Ekokylä, Suomen Lantakaasu, Biopir, and Vantaan Energia.

In 2023 the company sold its legacy contaminated soil and groundwater remediation business to Suomen Erityisjäte Oy and refocused on biogas, biological methanation, and biogeenic CO2 utilization. The forward strategy is to extend the EPC core into emerging synthetic-fuel and carbon-negative value chains through a wholly-owned subsidiary Carbonground Oy (carbonization, voluntary carbon credits), a partnership with Liquid Sun on electro-Sustainable Aviation Fuel (e-SAF), a partnership with Germany's Sauter Biogas GmbH for the Finnish market, and pilots with HSY and Vantaan Energia on biological methanation and carbon-negative concepts. The company has 11-50 employees, remains privately held under founder/management ownership (CEO Antti Myllärinen is a shareholder), and has executed international projects in Vietnam, Zambia, Namibia, and China alongside its Finnish core.

Core offering

Doranova designs, builds, and commissions biogas plants on a turnkey EPC basis using its three proprietary anaerobic digestion concepts (Wetferm for wet substrates, Solidferm for high-solids wet substrates, and the patented Hardferm for dry substrates). The company also provides landfill gas collection, utilization, and treatment systems for waste management operators, together with feasibility studies, permitting, process and basic engineering design, and biological methanation research.

Product overview

Doranova is a Finnish environmental technology company designing and building biogas plants. The product portfolio consists of three main patented biogas plant concepts: Wetferm (wet fermentation for slurries and biowaste), Solidferm (high-solids wet fermentation for dry manures and grass biomasses), and Hardferm (dry anaerobic digestion for challenging substrates with high impurity content). Supporting services include landfill gas solutions (collection systems and measurements), preparatory studies, licensing, and design services. The company also develops advanced technologies including biological methanation, carbonization, and collaborates on e-SAF (electro-Sustainable Aviation Fuel) production with Liquid Sun. Doranova's subsidiary Carbonground Oy focuses on carbonization solutions.

Products and services

• Wetferm biogas plants Doranova's wet anaerobic digestion concept used to deliver biogas plants that process pumpable substrates such as manure, sewage sludge, and other liquid organic residues; sold to agricultural operators, municipalities, and energy producers in Finland and internationally.
• Solidferm biogas plants Doranova's high-solids wet fermentation concept enabling biogas plants to process substrates with elevated dry-matter content that traditional wet digesters cannot handle; targeted at farms and food-industry operators with tougher feedstocks.
• Hardferm dry fermentation biogas plants Doranova's patented dry anaerobic digestion concept delivered as turnkey biogas plants (industrial-scale and farm-scale) for substrates that are difficult to handle in wet or high-solids reactors, including dry manure and high-dry-matter agricultural residues.
• Landfill gas collection and utilization systems End-to-end landfill gas collection, treatment, and utilization systems (extraction wells, piping, treatment, and energy recovery) sold to municipalities, water utilities, and waste management operators needing landfill methane capture and renewable energy generation.
• Feasibility studies, permitting and engineering design services Consultancy and engineering services covering feasibility studies, environmental permitting, and process and basic engineering design for biogas and landfill gas projects, sold as standalone pre-project deliverables to plant owners and developers.
• Biological methanation technology (biogenic CO2 + H2 → renewable methane) Proprietary biological methanation technology that converts biogenic CO2 with hydrogen into renewable methane; developed via a Lappeenranta-based pilot project jointly with Slovenian research partners, marketed to renewable gas producers.
• Carbonization (biochar) technology Doranova's emerging pyrolysis-based carbonization technology, developed with Carbonground, that converts biological residues and digestate into biochar for carbon sequestration and soil amendment.
