Hydryx Raises €2.5M To Fight Landfill Methane

The round was led by impact investor Marcel Smits and Graduate Entrepreneur, with support from a network of mission-driven angel investors.

“This investment enables us to drastically reduce methane emissions across Europe; right now, when it matters most,” added CEO Anthonie Jacobson.

Hydryx’s Seed funding aligns with a broader 2025 trend of ClimateTech and WasteTech startups attracting investment to cut methane and waste emissions.

Sweden’s Agteria Biotech raised €6 million for livestock methane reduction, while Italy’s Resilco secured €5 million to convert industrial waste into raw materials. Hydryx’s landfill methane focus positions the Netherlands within Europe’s growing circular emissions economy.

“Hydryx has the biggest ‘bang for your buck’ climate solution that I have seen,” said lead investor Marcel Smits.

Founded in 2023 Hydryx is a ClimateTech startup tackling methane emissions from landfills by combining automation and data-driven solutions. CEO Anthonie Jacobson and COO Joren Tangelder developed a methane management system that integrates with existing infrastructure to capture gas before it escapes, turning it into green energy.

The solution reduces emissions, generates revenue for landfill operators and demonstrates that sustainability can be economically smart. Methane from landfills is 86 times more potent than CO₂ and has a greater climate impact than aviation and shipping combined. Globally, around 70% of waste is still landfilled, producing methane for decades after closure.

Even in modern landfills roughly 60% of gas escapes into the atmosphere. Hydryx’s technology maximizes recovery, converting more gas into electricity, heat, or renewable natural gas. In partnership with Dutch waste management company Renewi, the system has already achieved a 40% increase in green energy generation, proving the potential of landfill methane as a clean energy source.
