Envigas

What Envigas does

Envigas is a Swedish pyrolysis technology company that converts certified Nordic stemwood (pine and spruce) residuals into three outputs: HQ BioCarbon (the primary product), pyrolysis oil, and syngas. Operations center on a commercial-scale plant in Bureå, Skellefteå, with headquarters in Stockholm. The proprietary 5-step process runs at approximately 600°C in an oxygen-free environment with precision control of residence time and selective condensation, yielding BioCarbon at 90-95% carbon content (C-fix), low ash, low moisture, and minimal PAH content, certified by the European Biochar Foundation.

The company's primary commercial focus is supplying metallurgical-grade biocarbon to the steel industry as a fossil-coal substitute for use as a reducing agent in blast furnaces, injection, and skimming applications. Revenue is generated through direct, negotiated long-term supply agreements with major Nordic stainless-steel producers; Outokumpu has a contractual guarantee for at least 50% of current and future volumes and a 20% equity stake, and SSAB and Höganäs are also named customers. Side streams (pyrolysis oil and syngas) extend the addressable market into fuels, chemicals, and potentially bio-graphite/carbon black, while research partnerships with Swerim and RISE support metallurgical validation.

Envigas is in an active scaling phase. Current Bureå design capacity is approximately 5,000 tonnes BioCarbon and 2,000-3,000 tonnes pyrolysis oil per year, with a target to reach 150,000 tonnes annually by 2030. The company is advancing a joint feasibility study with Skellefteå Kraft for a large-scale Hedensbyn facility and is pursuing the necessary environmental permits. Funding to date includes a SEK 22.3M Klimatklivet grant (2018), a ~SEK 50M first-commercial-plant round (2019), and a 9.9 MEUR strategic investment from Outokumpu (2023).

Revenue model

1. BioCarbon Sales: Sale of high-quality HQ BioCarbon to steel and metallurgical industry for use as reducing agent in blast furnaces, replacing fossil coal. Long-term supply agreements with major customers like Outokumpu guaranteeing at least 50% of production volumes.
2. Pyrolysis Oil Sales: Sale of pyrolysis oil produced from condensable phase of syngas. Can be used as fuel for refineries, heating oil for CHP systems, or as binder in asphalt/briquetting.
3. Syngas/Synthesis Gas Sales: Sale or internal use of non-condensable syngas for heating/cooling applications, CHP systems, or post-processing to methane or hydrogen for chemical/metallurgical industry.

Core offering

Envigas builds, owns, and operates high-precision, large-scale pyrolysis plants that convert organic biomass residuals (Nordic stemwood sawdust, shavings, and wooden pellets) into HQ BioCarbon, pyrolysis oil, and syngas through heating at approximately 600°C in an oxygen-free environment. The company focuses on the steel and metallurgical sector, where its HQ BioCarbon replaces fossil coal as a reducing agent in blast furnaces and other metallurgical applications.

Product overview

Envigas operates as a pyrolysis technology company producing three interconnected products from forest industry residuals: HQ BioCarbon (solid carbon product for metallurgic applications), Pyrolysis Oil (liquid condensate for fuel/chemical applications), and Pyrolysis Gas/Syngas (energy source for internal process power or conversion to methane/hydrogen). The pyrolysis process converts biomass at approximately 600°C to maximize value from each feedstock particle, with yields of 20-25% biomass to BioCarbon and 60-70% to gas.

Functional benefit

Products and services

• HQ BioCarbon High-quality biocarbon produced via pyrolysis of Nordic stemwood (pine/spruce) residuals at approximately 600°C with precision residence time control. Carbon content (C-fix) of 90-95%, density 350-400 kg/m3, volatile matter 2-3%, ash less than 3%, moisture 1-2%, and almost free of all PAHs. Used as a reducing agent in blast furnaces, for injection and skimming in steel production, or post-processed to bio-based carbon black or bio-graphite for metallurgical, battery, and advanced materials applications.
• Pyrolysis Oil Liquid mixture of acids and hydrocarbons produced via selective condensation of the condensable phase of syngas from biomass pyrolysis. Can be refined into chemicals, used as transportation fuel blending component, as heating oil for CHP systems, or as binder in asphalt/briquetting.
• Pyrolysis Gas / Syngas Non-condensable gas phase from biomass pyrolysis with high heating value. Used for powering boilers in heating or cooling applications, for CHP systems, or post-processed into methane (CH4) or hydrogen (H2) for chemical and metallurgical industry use.

Direct peers

• Pyreg GmbH: German manufacturer of pyrolysis carbonization plants producing biochar from biomass residuals for agricultural and industrial customers. Pyreg competes directly with Envigas on the technology, feedstock-to-biochar conversion, and certified biochar output side.
• Carbofex: Finland-based industrial-scale biocarbon producer using pyrolysis of woody biomass, supplying steel and metallurgical customers. Carbofex is one of the closest direct competitors in the Nordic HQ BioCarbon-for-steel market alongside Envigas.
• Char Technologies: Canadian pyrolysis company producing high-purity biocarbon and renewable natural gas from wood and wood-waste feedstock. Comparable to Envigas in combining a metallurgical-grade solid carbon product with energy byproducts from the same process.

Others

• CarboMax: Northern European supplier of coal-based products to the steel and foundry industry and a minority shareholder of Envigas. Closely related channel partner rather than a direct pyrolysis competitor.
• Outokumpu: Finland-based global stainless-steel major and Envigas's largest customer and 20% shareholder with a guaranteed 50% offtake. Strictly a customer/investor relation, not a direct competitor, but the single most important commercial counterparty in the investment thesis.
• Skellefteå Kraft: Swedish municipal utility and renewable energy producer co-developing the Hedensbyn biocarbon facility with Envigas. Not a competitor, but a strategic partner providing energy, biomass, and infrastructure for the next plant.

Emerging players

• Sonnenerde GmbH: Austrian producer of certified biochar from biomass pyrolysis for soil amendment and industrial applications. Same pyrolysis-based carbonization technology and feedstock type as Envigas, though primary focus is agricultural rather than metallurgical.
• Newlight Technologies (AirCarbon): US-based producer of AirCarbon, a bio-based plastic-alternative material made from captured carbon, with pyrolysis-adjacent technology. Comparable to Envigas in producing a high-purity carbon product from waste streams for industrial substitution.
• Carbon Gold Ltd: UK biochar producer using pyrolysis of woody biomass for horticultural and industrial applications. Adjacent comparator to Envigas's pyrolytic BioCarbon technology and feedstock approach.

Broad incumbents

• Topsoe: Danish industrial decarbonization technology provider active in biofuels, green hydrogen, and hard-to-abate sectors including steel. Larger, diversified incumbent whose steel-decarbonization portfolio overlaps with the end-customers Envigas serves.
