What Vow does

Vow ASA is a publicly listed Norwegian industrial-technology group (Oslo Børs: VOW) that designs, engineers and delivers proprietary systems for converting biomass, sewage sludge, plastic waste, end-of-life tyres and onboard ship waste into clean energy, biochar and renewable carbon. It operates through three Business Units: Maritime Solutions (the Scanship brand — Advanced Wastewater Purification, Electrically Assisted Pyrolysis, and the Scanship Thermal Treatment Process, with 400+ systems installed on 175 cruise ships), Industrial Solutions (Etia/Biogreen screw-conveyor pyrolysis, CHE 5t rotary-drum pyrolysis, C.H. Evensen industrial heat-treatment furnaces, and Safesteril steam sterilization), and a dedicated Aftersales unit delivering spare parts, approved chemicals, service agreements and training across the global installed base. Headquartered in Oslo with engineering and manufacturing in Tønsberg, Fredrikstad, Compiègne and Gdynia, plus a U.S. chemicals/service operation in Miami, the group employs 242 people across 17 nationalities and seven offices.

Vow makes money primarily through engineered-to-order capital equipment sold directly to major European shipyards, cruise operators and industrial buyers, with disclosed per-contract values ranging from EUR 1.5M (ETIA plastic-to-fuel services) and EUR 3.4M (cruise retrofit) up to NOK 500M multi-vessel newbuild packages. Projects are typically preceded by Front-End Engineering Design (FEED) studies (Murfitts, Circon/ReCO2, Vow Green Metals) and are followed by multi-year delivery, commissioning and aftersales commitments, producing a project-equipment-plus-recurring-service revenue model. The Maritime segment carries the highest concentration of large multi-year contracts (deliveries extending to 2031–2032) and is the principal EBITDA contributor, while the Industrial Solutions segment is more diversified by geography and application but has been the source of recent profitability pressure (Q3 2025 EBITDA negative NOK 28.5M).

Financially, Vow reported FY2024 revenue of NOK 1,018.2M (+11% YoY) — its first year above NOK 1 billion — with EBITDA before non-recurring items of NOK 61.1M, a record NOK 1,680M order backlog at year-end, and an all-time-high NOK 1,449M backlog at Q3 2025. The company executed a fully underwritten NOK 250M rights issue in December 2024 to repair liquidity and amended DNB covenants in May 2025 (facility extended to Q3 2027, guarantees raised to NOK 100M). In 2025–2026, a new leadership team led by CEO Gunnar Pedersen (ex-Kongsberg Maritime) restructured the group into three P&L-owned Business Units and launched a profit improvement programme, while continuing to land major cruise newbuild orders (EUR 27M, EUR 29.6M, EUR 13.8M + options) and pivoting Industrial Solutions towards higher-value pyrolysis applications such as tyre recycling, plastic-to-fuel and biocarbon production.

Revenue model

1. Maritime equipment sales (newbuilds and retrofits): One-time equipment/project revenue from sale of Scanship AWP, EAP, and STTP systems to shipyards and cruise operators for newbuild and retrofit cruise vessels. Large-ticket contracts (EUR 3.4M to EUR 29.6M per vessel; NOK 500M multi-ship deals) with deliveries stretching across multiple years (2025–2031).
2. Industrial equipment and pyrolysis plant sales: One-time project revenue from sale of pyrolysis reactors (CHE 5t, Biogreen), C.H. Evensen heat-treatment furnaces, and Safesteril sterilization systems, often preceded by FEED studies and followed by commissioning and spare-parts supply. Includes pilot/trial units and large-scale plant deliveries (e.g., Vow Green Metals Follum reactor, Circon Caribbean Carbon Refinery, hydrocarbon-company plastic-to-fuel units).
3. Aftersales (spare parts, chemicals, service, training): Recurring lifecycle revenue from the Aftersales business unit: original spare parts packages, approved chemicals for AWP and biowaste systems, on-site inspections, preventive/corrective maintenance, remote support, system upgrades, training, and tailored service agreements for the global installed base of 400+ Scanship, 4,500+ C.H. Evensen, and 150+ Safesteril installations.
4. FEED studies and engineering services: Front-End Engineering Design (FEED) contracts and service agreements for prospective industrial customers (e.g., Murfitts Industries end-of-life-tyre pyrolysis plant, Circon/ReCO2 Carbon Refinery in the Caribbean), representing project-development service revenue that often converts into larger equipment orders.
5. Maintenance, spare-parts, and training contracts tied to equipment sales: Long-tail services and supply agreements (e.g., ETIA's EUR 1.5M services & supply agreement with an international hydrocarbon company for plastic-to-fuel units, including a six-month trial, maintenance support, spare parts, and training) bundled with pyrolysis technology deployments.

Core offering

Vow ASA designs, manufactures, and sells engineered capital equipment that converts waste streams (biomass, sewage sludge, plastic waste, end-of-life tyres, and onboard ship waste) into valuable resources (biochar, biocarbon, pyrolysis gas/oil, recovered carbon black) and clean energy. Through its Scanship brand it delivers integrated clean-ship solutions - advanced wastewater purification and waste-to-energy systems - to cruise newbuilds and retrofits; through C.H. Evensen, Etia (Biogreen/CHE 5t), and Safesteril it delivers industrial pyrolysis reactors, heat-treatment furnaces, and sterilization systems; and a dedicated Aftersales unit supplies spare parts, chemicals, service, and training to the global installed base.

Product overview

Vow ASA offers a platform-plus-modules architecture built around three Business Units (Maritime Solutions, Industrial Solutions, Aftersales) and a portfolio of acquired and developed brands/products. Maritime Solutions is delivered through the Scanship sub-brand, anchored by the Scanship AWP (Advanced Wastewater Purification) system and Electrically Assisted Pyrolysis (EAP) for onboard waste handling, alongside the Scanship Thermal Treatment Process (STTP). Industrial Solutions combines the Circular Solutions division (pyrolysis technologies CHE 5t and Biogreen) with the Heat Treatment division (C.H. Evensen industrial furnaces and Safesteril sterilization systems). Etia is the French technology company acquired in 2019 that develops the Biogreen pyrolysis technology, and Vow Automation is a joint venture with Controlpartner that builds advanced automation and digitized control systems tailored to Vow's industrial and maritime technologies. The Aftersales business unit provides global lifecycle support (spare parts, service, chemicals, technical expertise) across both Maritime Solutions and Industrial Solutions installations, functioning as a unified customer interface throughout the full system lifecycle.

Direct competitor to Vow/Etia in the plastic-to-fuel and waste-to-resource pyrolysis space and a fellow Norwegian listed cleantech peer.
• Pyrum Innovations: German pyrolysis technology company specializing in end-of-life tire pyrolysis producing recovered carbon black, pyrolysis oil, and gas. Direct competitor to Vow/Etia in the ELT pyrolysis vertical where Vow has signed the Murfitts/ITOCHU FEED partnership.
• Enviro Systems (Enviro): Swedish company with patented pyrolysis technology for end-of-life tires and rubber waste, producing recovered carbon black, oil, steel, and gas. Direct European peer to Vow/Etia's Biogreen in tire and rubber pyrolysis.
• Ipsen: Global supplier of industrial heat treatment furnaces for the aerospace, automotive, and energy industries. Direct competitor to Vow's C.H. Evensen subsidiary in customized industrial heat treatment furnaces, particularly as Vow targets decarbonization and electrification of heat treatment processes.

Emerging players

• Carbios: French biotech company developing enzymatic recycling processes for PET plastics and other bioprocesses. Thematic peer to Vow/Etia in circular economy and waste-to-resource chemistry with a partially overlapping French industrial customer base and partnership network.
