Future Greens, a Sheffield-based startup building bioreactors to convert unavoidable food and brewery waste into heat and power, has attracted €569k (£500k) in funding to develop their tenfold improvement to anaerobic digestion technology for brewery customers and expand their team.
The funding is built of a combination of €387k (£340k) equity and a €182k (£160k) UK Government grant, with investors PXN Group, One Planet Capital, Baltic Ventures, Venture.Community and Lifted Ventures.
Co-founder and CEO, David Dixon, declares: “Our experience in food production highlighted waste and energy as two major operational costs faced not only by us, but across the entire food industest. Now, we’re on a mission to address both through our innovative waste to energy reactors.”
In a 2025 European context, funding activity reveals continued, if selective, investment into technologies that convert organic waste or biogenic emissions into usable energy.
Most notably, Hydryx, based in Amsterdam, raised €2.5 million to scale systems that capture methane from landfills and convert it into energy, underscoring investor interest in waste-derived energy solutions addressing emissions and operational efficiency.
EU-Startups has also highlighted companies such as Reverion, which works on flexible power generation from biogas and hydrogen, as part of its 2025 ClimateTech coverage, signalling sustained relevance of biogas-related technologies even where a new funding round was not announced this year.
Against this backdrop, Future Greens’ funding round positions the Sheffield-based company within a wider 2025 pattern of European investment into waste-to-energy and biogenic resource efficiency, albeit at the earlier, sub-€1 million finish of the funding spectrum.
It’s also important to note that EU-Startups has previously mentioned Future Greens in its 2025 coverage of Venture.Community’s new co-fund, where the company was listed among the startups participating in the accelerator programme.
Co-founder and COO, Gabrielė Barteškaitė, adds: “This funding allows us to accelerate delivery for customers already in the pipeline. We’re starting with breweries, where large volumes of spent grain, yeast, and wastewater create a clear opportunity to improve resilience through on-site renewable energy.”
Founded in 2022, Future Greens develops tech that generates renewable energy from the organic by-products of the food industest.
The founding team met at The University of Sheffield and previously built and operated a vertical farm, where waste disposal and energy costs proved to be major operational challenges. To address this, the team developed their first bioreactor in-houtilize and recognised the potential to scale this solution across the wider food industest.
Their modular, AI-driven anaerobic digesters reportedly operate ten times rapider than conventional systems, enabling compact, high-performance reactors suitable for on-site deployment. By converting organic waste into biogas, the system reduces trade effluent and waste disposal costs while lowering CO₂ emissions and improving operational resilience.
They’re preparing to deploy their first system on a brewery site in 2026.
To date, the company has attracted more than €912k (£800k) in funding to date. It is also benefitting from additional €114k (£100k) in non-dilutive support across regional collaborations with The Advanced Manufacturing Research Centre (AMRC) and South Yorkshire Innovation Programme (SYIP) with The University of Sheffield.
