Barcelona-based cleantech startup WtEnergy has raised €10 million to accelerate the deployment of its industrial waste-to-energy technology. The funding marks a decisive growth phase for the company as it scales commercial projects, strengthens engineering capabilities, and expands into new international markets. WtEnergy aims to transform how heavy industry sources energy by converting non-recyclable waste and biomass into renewable syngas that replaces fossil fuels.
Founded in 2017, WtEnergy built its strategy around a simple but urgent reality: industries need high-temperature heat and reliable power, yet fossil fuels dominate those applications. Solar and wind power offer clean electricity, but they cannot directly deliver the intense thermal energy required in cement kilns, chemical reactors, or large-scale manufacturing furnaces. WtEnergy addresses that gap with advanced gasification technology that turns waste streams into a clean, usable fuel.
Turning Waste into High-Value Energy
WtEnergy uses bubbling fluidized bed gasification, a thermochemical process that converts solid waste and biomass into synthetic gas, commonly known as syngas. The system subjects feedstock to very high temperatures in a controlled oxygen environment. Instead of burning waste outright, the process breaks down materials at a molecular level and produces a combustible gas mixture rich in hydrogen, carbon monoxide, and methane.
The company designs its systems to handle diverse feedstocks. Operators can process forestry residues, agricultural by-products, demolition wood, refuse-derived fuel, sewage sludge, and end-of-life tires. This flexibility allows industrial partners to adapt the technology to local waste streams and regional supply chains.
Syngas offers multiple applications. Industrial facilities can use it directly to generate heat and steam. Power plants can feed it into turbines or engines for electricity generation. Chemical producers can refine it into green hydrogen, methanol, or ammonia. Each pathway supports industrial decarbonization while creating value from materials that previously ended up in landfills or low-efficiency incinerators.
Solving Industrial Decarbonization Challenges
Heavy industry accounts for a significant share of global carbon emissions. Cement, steel, chemicals, and pulp and paper production rely on continuous high-temperature processes that demand stable and energy-dense fuels. Many companies struggle to reduce emissions because electrification cannot meet all thermal requirements, and hydrogen infrastructure remains limited in scale and availability.
WtEnergy positions its technology as a drop-in alternative to fossil fuels. Industrial plants can integrate syngas into existing combustion systems with limited retrofitting. This approach lowers the barrier to adoption and reduces capital expenditure compared to building entirely new energy systems. Companies can cut carbon emissions while maintaining production efficiency and operational continuity.
Cement producers represent a particularly strong use case. Cement manufacturing generates substantial carbon emissions from both fuel combustion and chemical reactions during clinker production. By replacing petroleum coke or coal with syngas derived from waste, cement plants can significantly reduce their fuel-related emissions. WtEnergy offers a pathway that aligns environmental goals with operational practicality.
Strengthening the Circular Economy
WtEnergy’s model reinforces circular economy principles. Instead of viewing waste as a disposal problem, the company treats it as an energy resource. Europe and many other regions continue to generate large volumes of non-recyclable waste. Landfills contribute methane emissions, while incineration often fails to capture the full energy value of materials.
WtEnergy’s gasification technology extracts higher-value energy content from waste streams and channels it directly into industrial use. This strategy reduces landfill dependency, lowers greenhouse gas emissions, and supports local energy independence. Industries can source fuel from nearby waste streams instead of importing fossil fuels from distant markets.
The €10 million funding will enable WtEnergy to accelerate project development across multiple industrial sectors. The company plans to scale its engineering teams, enhance plant automation systems, and expand manufacturing capacity for modular gasification units. These steps will shorten deployment timelines and improve system performance.
Expanding Across Europe and Beyond
WtEnergy already operates in Spain and collaborates with partners across Europe. The new capital will strengthen its footprint in key industrial regions where policymakers enforce stricter climate regulations. Governments across the European Union have introduced carbon pricing mechanisms and emissions targets that push companies to adopt low-carbon technologies. WtEnergy’s solution aligns with these policy trends and offers measurable emission reductions.
Beyond Europe, the company sees strong opportunity in North America and parts of Asia. Rapid industrialization, rising waste generation, and tightening environmental standards create favorable conditions for waste-to-energy systems. WtEnergy intends to form strategic partnerships with engineering firms, industrial operators, and project developers to enter these markets efficiently.
Advancing Innovation and Technology
WtEnergy does not limit its ambitions to heat and power generation. The company actively explores advanced applications of syngas, including green hydrogen production. By integrating gasification with hydrogen separation technologies, WtEnergy can create renewable hydrogen from waste-derived sources. This capability supports industries that seek low-carbon feedstocks for refining, fertilizer production, and chemical synthesis.
Research and development remain central to the company’s growth strategy. Engineers continue to optimize reactor design, improve feedstock flexibility, and enhance digital monitoring systems. Advanced analytics allow operators to monitor temperature profiles, gas composition, and system efficiency in real time. These innovations improve reliability and lower operational costs.
The €10 million funding round will accelerate these R&D initiatives. WtEnergy plans to refine modular plant configurations that suit different scales of industrial demand. Smaller units can serve medium-sized factories, while larger integrated systems can power major industrial complexes. This modular approach increases adaptability and supports faster market penetration.
Economic and Environmental Impact
WtEnergy’s business model generates both environmental and economic benefits. Companies that adopt the technology can reduce fuel expenses by utilizing locally sourced waste streams. They can also mitigate exposure to volatile fossil fuel prices. In regions with carbon taxes or emissions trading systems, lower emissions translate directly into financial savings.
Communities also benefit from reduced landfill usage and improved waste management infrastructure. Municipalities can partner with industrial facilities to supply feedstock, creating regional value chains that keep resources in circulation. This integration strengthens local economies while advancing sustainability goals.
Investors have increasingly recognized the importance of scalable climate technologies. Clean energy startups that offer tangible industrial solutions attract strong interest in the current funding environment. WtEnergy’s ability to combine proven engineering principles with a clear commercial pathway positions it as a competitive player in the cleantech sector.
Leadership and Vision
WtEnergy’s leadership team drives the company with a strong focus on practical decarbonization. The founders designed the technology to integrate with real-world industrial constraints rather than relying on theoretical breakthroughs. This pragmatic mindset has allowed the company to move from concept to commercial deployment within less than a decade.
The new funding milestone signals confidence in WtEnergy’s long-term vision. The company aims to establish itself as a global reference in waste-to-energy solutions for heavy industry. By expanding installations, advancing hydrogen applications, and strengthening partnerships, WtEnergy seeks to accelerate the transition toward a lower-carbon industrial system.
As industries face mounting pressure to meet climate targets, solutions that combine reliability, scalability, and environmental impact will define the next phase of energy transformation. WtEnergy stands at the intersection of waste management and industrial energy, turning discarded materials into a strategic resource. With €10 million in new backing, the company now moves forward with greater momentum to reshape how industry powers its future.
