Green Fuels

What Green Fuels does

Green Fuels Limited is a UK-headquartered (Berkeley, Gloucestershire) renewable fuels company founded in 2003 that designs, manufactures and sells modular container-based biodiesel processing equipment under its FuelMatic brand (GSX, GSX3, GSX20 models), alongside proprietary conversion technologies for sustainable aviation fuel (SABR, FIREFLY) and sustainable marine fuel (SALMO) derived from waste feedstocks including used cooking oil, animal fats, agricultural residues, sewage sludge and aquaculture waste. The company operates a multi-revenue model spanning one-time equipment sales, professional consulting services (feasibility studies, feedstock verification, carbon auditing), technology licensing, and a growing own-label fuel production pillar with operational refineries in Berkeley, UK and Juiz de Fora, Brazil. Green Fuels serves aviation (Wizz Air, GOL Linhas Aéreas), maritime, municipal/road transport (Municipality of Juiz de Fora), and emerging-market government clients via direct sales and a network of joint ventures (Aris Bioenergy in India, Wakud International in Oman, Green Fuels Ventures América Latina in Brazil), with equipment deployed in more than 80 countries.

The company's R&D engine is Green Fuels Research, a dedicated division established in 2014 with university-level facilities in Berkeley, which has attracted £12m/$16m in direct and indirect research grants and collaborates with more than 20 universities globally on novel feedstocks, catalysts, and waste valorization. Key technologies are patented, and the company holds a Royal Warrant of Appointment originally granted in 2013 by HRH the Prince of Wales. Green Fuels is mid-transition from an equipment and licensing business to a vertically integrated global sustainable fuel producer targeting the aviation and maritime decarbonization markets, with announced offtakes including 525,000 tonnes of SAF to Wizz Air over 15 years starting 2028 via its Firefly spin-off.

Commercial scale remains modest (11-50 employees, no disclosed revenue) and the transition is capital-intensive, evidenced by the recent £5m Wizz Air equity injection into Firefly, ongoing reliance on UK and EU public grant funding, and joint-venture structures that share capital risk with regional partners while preserving Green Fuels' technology licensing upside.

Core offering

Green Fuels designs, manufactures and sells modular biofuel processing equipment (the FuelMatic GSX line) that converts waste feedstocks such as used cooking oil, animal fats, sewage sludge and agricultural residues into biodiesel, sustainable aviation fuel (SAF) and sustainable marine fuel. The company complements equipment sales with proprietary refining technologies (SABR, FIREFLY, SALMO), own-label fuel production from company-owned refineries in the UK and Brazil, and biofuels consulting services.

Product overview

Green Fuels is a UK-based pioneer in renewable fuels (founded 2003) operating across three business pillars: (1) biofuel processing equipment manufacturing (FuelMatic GSX line), (2) proprietary advanced fuel production technologies (SABR for SAF, FIREFLY for sewage-derived jet fuel, SALMO for marine fuel from aquaculture waste), and (3) own-label fuel production through strategically located refineries. The company serves road transport, aviation, and maritime sectors across 80+ countries, with its R&D division Green Fuels Research developing new feedstocks and processing pathways. Consulting services complement the technology offering.

Products and services

• FuelMatic Biodiesel Processing Equipment Patented, modular container-based biodiesel processing equipment (FuelMatic GSX, GSX3 and GSX20 models) that converts waste cooking oils and animal fats into renewable biodiesel. Designed around standard container frames for transport, installation and operation, the equipment has been sold to customers in more than 80 countries for distributed and large-scale fuel production.
• SABR Sustainable Aviation Fuel Technology SABR (Sustainable Aviation through Biofuel Refining) is Green Fuels' proprietary technology for producing fully waste-derived sustainable aviation fuel from feedstocks such as sewage sludge and agricultural residues. It is licensed and deployed within the FlexJET project (the first commercial exclusively waste-to-jet facility in Europe) and other SAF initiatives.
• FIREFLY Sewage-to-Jet Fuel Technology FIREFLY is a sustainable aviation fuel technology originating from Green Fuels laboratories that converts sewage sludge into drop-in jet fuel. As a spin-off entity, FIREFLY has secured a £5m equity investment from Wizz Air and a binding offtake agreement for up to 525,000 tonnes of SAF over 15 years from 2028, with projected 90% GHG reduction versus fossil jet fuel.
• SALMO Marine Fuel Technology SALMO (Sustainable Aquaculture Leading to Marine Opportunities) is Green Fuels' process for converting waste biomass from salmon farming into drop-in marine fuels that are compatible with existing marine diesel engines without modification. It is aimed at shipping operators seeking sustainable fuel for long-route vessels.
• Biofuels Consulting Services Wide-ranging advisory services covering site selection, feasibility studies, business planning, feedstock verification, carbon auditing, environmental impact assessment and expert witness services.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Neste: Global leader in renewable diesel (HVO/HEFA) and SAF made from waste and residues. Largest incumbent in Green Fuels' core end markets (road biodiesel and SAF), with vastly greater scale and capital. Directly competes for airline and government fuel offtake contracts.
• Aemetis: US renewable diesel and SAF producer using waste feedstocks (tallow, distillers corn oil). Competes for airline SAF offtake contracts and is building out cellulosic pathways akin to Green Fuels' advanced waste streams.
• BP (Castrol/biofuels): Majors are scaling SAF capacity and signing offtake with airlines. They compete head-to-head with Green Fuels for the same airline SAF contracts and route-to-market partnerships.

Direct peers

• Velocys: UK-based technology company developing small-to-medium scale Fischer-Tropsch plants for renewable jet fuel and diesel from waste feedstocks. Most directly comparable to Green Fuels on distributed waste-to-jet technology targeting aviation decarbonization.
• LanzaTech: Carbon capture-to-fuels company using proprietary gas fermentation to produce ethanol and SAF from industrial off-gases and biomass. Direct technology peer in the waste-to-SAF/jet fuel category with similar licensing-based business model.
• SkyNRG: SAF-focused specialist supplying airlines with sustainable aviation fuel and developing dedicated production facilities. Closest competitor in the airline SAF offtake segment targeted by Green Fuels' Wizz Air deal.
• Fulcrum BioEnergy: US-based waste-to-jet fuel company using municipal solid waste and biosolids to produce SAF via Fischer-Tropsch. Direct technology and feedstock analogue to Green Fuels' FIREFLY sewage sludge-to-SAF pathway.
• BDI-BioEnergy International: Austrian EPC contractor and technology supplier for small-to-large scale biodiesel plants from waste oils and fats. Most direct equipment-focused peer to Green Fuels' FuelMatic distributed-scale plants business.

Emerging players

• LanzaJet: ATJ (alcohol-to-jet) SAF producer spun out of LanzaTech with backing from Suncor, BP, and Mitsui. Competes in the same waste-to-jet end market using similar alcohol-to-jet technology pathway to Green Fuels' SABR process.
• SunFire GmbH: German cleantech company developing e-fuels and biofuels (including synthetic SAF) using biomass and CO2/hydrogen. Comparable emerging player pursuing aviation fuel decarbonization through alternative pathways in Europe.
