Waste to Energy Advanced Solutions (WtEnergy), a Barcelona-based company specialising in the energy recovery of waste and biomass through gasification technologies, has closed a €10 million financing round to support the execution of its project pipeline, plant standardisation, organisational strengthening, development of new syngas applications, and European expansion.
The round led by SC Net Zero Ventures, Suma Capital’s Climate Tech fund, focused on scaling growth-stage companies, with participation from Shell Ventures and existing shareholder Cemex Ventures.
“This financing round represents a key milestone for Waste to Energy Advanced Solutions. It supports the accelerated deployment of our technology at an industrial scale, while helping our customers recover energy from their waste, turning it into a competitive source of alternative energy and new low-carbon molecules. Having partners such as Shell Ventures, Cemex Ventures and Suma Capital strengthens our vision and encourages us to take the next step in our growth,” said Andrés Ponce, CEO of WtEnergy.
WtEnergy was founded in 2017 by Ponce, and in 2019, Antonio Crous joined him as co-founder to scale the business commercially and develop the implementation of technology within strategic industries and sectors.
According to WtEnergy, the European industry faces the dual challenge of reducing emissions in energy-intensive processes while managing increasing volumes of industrial waste. The Spanish startup claims to tackle this by developing and operating its own gasification technology, which transforms waste and biomass into syngas (synthesis gas). It notes that this circular process gas can replace fossil fuels in energy-intensive industrial processes and can also be processed to produce hydrogen, methanol and sustainable aviation fuel (SAF).
WtEnergy’s small and medium-sized modular plants (5–50 MW) are designed to be directly integrated into industrial facilities. The company claims that this enables its customers to reduce their energy costs, lower CO₂ emissions and advance their circular economy objectives by recovering waste that would otherwise end up in landfills or incinerators.
As per the company, its thermochemical conversion process is based on the transformation of solid fuels into clean and versatile synthesis gas via the atmospheric gasification process. “The process takes place in a bubbling fluidised bed gasifier, where fuel and fluidising agent react under autothermal reduction conditions to generate synthesis gas. This gas is then treated by the WtEnergy reforming process to remove all contaminants present on the residue,” WtEnergy stated on its website. The two key uses of clean syngas are power generation and thermal applications.
It currently focuses on key sectors for industrial decarbonisation, including cement, paper, rendering, chemicals and ceramics, where it has projects in operation and at advanced development stages.
With this capital, WtEnergy aims to further strengthen its position in the energy recovery of industrial waste and biomass in Spain and Europe, thereby offering the industry a solution to reduce emissions, optimise energy costs and move towards a more sustainable production model.
“We are very pleased to support Waste to Energy Advanced Solutions in this new phase of growth. Their technology, team and the industrial traction they have already demonstrated fit perfectly with our investment strategy in technological solutions with proven traction and strong scaling potential, enabling progress towards a more efficient, low-carbon industrial model,” said Natalia Ruiz, Partner at Suma Capital.
In 2023, the European Union awarded Cemex and WtEnergy Advanced Solutions a €4.4 million grant for the implementation of a novel waste-to-fuel technology utilising synthetic gas at its Alicante cement plant in Spain.
