The new investment reaffirms Cemex Ventures’ commitment to the startup, driven by the success of the CLYNGAS project and a €4.4 million grant from the European Union.
Cemex Ventures, the corporate venture capital arm of Cemex, announced today a new investment in Waste to Energy Advanced Solutions (WtEnergy), a leading startup specializing in the conversion of non-recyclable solid waste and biomass into clean energy.
With this capital injection, Cemex Ventures strengthens its commitment to WtEnergy, supporting the development and scalability of a technology with the potential to upgrade waste into low-carbon syngas, clean hydrogen, and other bioproducts. This investment is made with the objective of accelerating the integration of clean energy sources into Cemex’s global clinker and cement manufacturing operations, a cornerstone of its decarbonization strategy.
“WtEnergy perfectly embodies the type of solutions we aim to promote within our circular economy and clean energy strategy,” said Alfredo Carrato, Investment Manager at Cemex Ventures. “The advancement of technologies that can turn waste into clean fuels and low-carbon solutions is essential for the decarbonization of the construction sector. With this new investment, we reinforce our commitment to supporting startups that are redefining the industry’s energy future and creating tangible value across the cement value chain.”
Cemex Ventures’ decision to increase its participation in WtEnergy is based on measurable progress and growing institutional recognition of the technology:
1. €4.4 Million EU Innovation Fund Grant: In collaboration with Cemex, WtEnergy has received the support of the European Union Innovation Fund through a grant aimed at developing its advanced waste-to-fuel conversion technology. This financial backing highlights the potential of the solution as a clean and scalable energy alternative for the heavy industry.
2. Leadership in clean hydrogen production via EU Horizon Europe HYIELD Project: WtEnergy leads the innovative HYIELD project at Cemex’s Alcanar plant in Spain, awarded with a €10M grant by Horizon Europe and focused on transforming bio-residues into high-purity clean hydrogen. The project’s success positions WtEnergy as a key player in the energy transition and circular economy based on sustainable resources.
This investment reinforces Cemex’s commitment to its “Future in Action” program, which aims to achieve net-zero CO₂ emissions by 2050. The use of alternative fuels with a high biomass content is one of the main levers of Cemex’s 2030 decarbonization roadmap, validated by the Science-Based Targets initiative (SBTi) under the 1.5°C scenario.
