The Amsterdam ClimateTech startup aims to cut methane emissions and expand its landfill energy systems across Europe.
Hydryx, an Amsterdam-based ClimateTech startup developing methane management systems for landfills, has raised €2.5 million in a seed round to scale its operations across Europe.
The round was led by impact investor Marcel Smits and Graduate Entrepreneur, joined by several mission-driven angel investors. The funding will help Hydryx deploy its technology at more landfill sites and further reduce methane emissions, one of the most potent greenhouse gases.
Founded in 2023 by Anthonie Jacobson (CEO) and Joren Tangelder (COO), Hydryx focuses on turning methane emissions into valuable energy. Its system integrates with existing landfill infrastructure to capture methane before it escapes into the atmosphere, converting it into electricity, heat, or renewable natural gas.
“Hydryx has the biggest ‘bang for your buck’ climate solution that I have seen” said lead investor Marcel Smits. “This investment enables us to drastically reduce methane emissions across Europe; right now, when it matters most” added Anthonie Jacobson.
Hydryx’s technology, already proven in partnership with Dutch waste management company Renewi, has shown a 40% increase in green energy generation from landfill gas compared with standard systems. The company’s approach turns what has long been a climate liability into a new revenue stream for landfill operators.
Methane, which is 86 times more potent than CO₂, accounts for about 6% of global climate change, more than the aviation and shipping sectors combined. Landfills are responsible for a significant share of those emissions, with about 60% of landfill gas escaping untreated.
Hydryx joins a broader wave of European startups, such as Agteria Biotech in Sweden and Resilco in Italy, working to monetize waste streams and reduce emissions. Its landfill-focused model positions it as one of the few Netherlands-based players targeting the methane-to-energy opportunity at scale.
With its technology validated and capital secured, Hydryx now aims to roll out its system across Europe’s network of active and closed landfill sites, transforming one of the dirtiest sources of emissions into a source of green growth.
