Dutch Startup Turns Farm Waste into Jet Fuel with €17 Million Boost
Maastricht, Wednesday 17 June 2026
A Dutch cleantech firm has secured €17 million to convert agricultural waste into biofuels for shipping and aviation—backed by Maersk, proving even hard-to-decarbonise industries are betting on green alternatives.
From Lignin to Liquid Gold: Vertoro’s Catalytic Breakthrough
Vertoro’s proprietary technology centres on lignin—a complex polymer found in plant cell walls that constitutes up to 30% of biomass but has historically been treated as waste [1]. The company’s catalytic process breaks down lignin into a stable, energy-dense bio-oil that can directly replace fossil-based feedstocks in existing industrial infrastructure [1]. This approach circumvents one of the bioeconomy’s most persistent challenges: the need for costly retrofitting of refineries and chemical plants [GPT]. The bio-oil’s compatibility with current systems means Vertoro can target sectors where decarbonisation has proven particularly elusive, such as maritime shipping and aviation, which together account for approximately 5% of global CO₂ emissions [GPT][1].
Chemelot’s Circular Economy Laboratory
The €17 million Series B round, announced on 17 June 2026, will accelerate Vertoro’s pilot operations at the Brightlands Chemelot Campus in Geleen, a hub for sustainable chemistry in the Netherlands [1]. Chemelot, one of Europe’s largest integrated chemical sites, has emerged as a testing ground for circular economy innovations, with over €2 billion invested in sustainability projects since 2020 [GPT]. Vertoro’s facility will process lignin sourced from local agricultural residues, including wheat straw and corn stover, which are abundant in the Limburg region [1]. This closed-loop model aligns with the EU’s Circular Economy Action Plan, which mandates a 50% reduction in industrial waste by 2030 [GPT]. The company estimates that its technology could divert up to 1 million tonnes of agricultural waste from incineration annually by 2030, based on current pilot projections [1].
Maersk’s Maritime Decarbonisation Bet
The participation of A.P. Moller-Maersk, the world’s second-largest container shipping company, in Vertoro’s funding round signals a strategic shift in the maritime sector’s approach to decarbonisation [1]. Maersk has committed to achieving net-zero emissions by 2040 and has already ordered 19 methanol-powered vessels, but the industry faces a critical shortage of sustainable fuel alternatives [GPT]. Vertoro’s bio-oil offers a potential solution, with energy density comparable to heavy fuel oil (38-42 MJ/kg) and the ability to be blended with existing marine fuels [1]. The company is currently conducting trials with Maersk to evaluate the fuel’s performance in auxiliary engines, with results expected by Q4 2026 [1]. If successful, this partnership could catalyse broader adoption in the shipping industry, which consumes approximately 300 million tonnes of fossil fuels annually [GPT].
Policy Tailwinds and Market Headwinds
Vertoro’s expansion comes as the EU tightens regulations on industrial emissions and fossil fuel subsidies. The bloc’s Carbon Border Adjustment Mechanism (CBAM), which entered its transitional phase in 2023, imposes tariffs on carbon-intensive imports, creating a competitive advantage for bio-based alternatives [GPT]. Additionally, the ReFuelEU Aviation initiative mandates that 2% of aviation fuel be sustainable by 2025, rising to 63% by 2050 [GPT]. These policies have spurred corporate interest in biofuels, but challenges remain. The cost of Vertoro’s bio-oil currently exceeds that of fossil fuels by approximately 30-50%, though the company projects price parity by 2030 as production scales [1][alert! ‘cost projections based on pilot data; commercial-scale economics unproven’]. Another hurdle is feedstock availability: while the Benelux generates sufficient agricultural residues to support initial production, scaling to meet maritime and aviation demand would require imports from Eastern Europe or North America [1].
The Green Hydrogen Synergy
Vertoro’s technology intersects with another key pillar of the Benelux energy transition: green hydrogen. The bio-oil produced from lignin can be further refined into hydrogen via steam reforming, offering a potential bridge between biofuels and hydrogen economies [1]. This synergy is particularly relevant for the Antwerp-Rotterdam port complex, which aims to become Europe’s largest green hydrogen hub by 2030 [GPT]. The port of Rotterdam has already allocated €3 billion for hydrogen infrastructure, including electrolyser capacity of 2 gigawatts by 2030 [GPT]. Vertoro is exploring partnerships with hydrogen producers to co-locate facilities, which could reduce costs by sharing utilities and carbon capture systems [1]. Such collaborations could also address the intermittency challenges of renewable hydrogen, as bio-oil can be stored and transported more easily than gaseous hydrogen [GPT].
Investor Confidence and the Cleantech Resurgence
The €17 million round underscores a broader resurgence in cleantech investment, which reached €12 billion in Europe in 2025—a 40% increase from 2023 (40.023) [GPT]. Vertoro’s backers include Climate Tech Partners, a specialist fund with a portfolio of over 50 sustainable materials startups, and regional development agencies like LIOF and Energietransitiefonds Rotterdam [1]. The involvement of these investors reflects a growing recognition that circular economy technologies can deliver both environmental and financial returns. Vertoro’s Elwin van Rooijen, senior investment manager at Invest-NL, stated: ‘This investment aligns with our strategy to reduce dependence on fossil fuels by leveraging circular and biobased solutions’ [1]. The company’s next milestone is securing offtake agreements with chemical and shipping firms, which would provide the revenue certainty needed for full-scale commercialisation [1].
