WtEnergy converts biomass and non-recyclable waste into a lower-carbon energy solution, which can be used in the short term as a fossil fuel alternative or be upgraded in the medium and long term to gases such as biomethane or pure hydrogen.

Cemex intends to incorporate this clean energy source into its clinker and cement manufacturing process, looking to further reduce the carbon footprint of its operations. Cemex aims to increase its fossil fuel substitution rate by 20 percentage points by 2030.

In June 2023, the European Union awarded Cemex and WtEnergy a €4.4 million grant for the implementation of WtEnergy’s novel waste-to-fuel technology utilizing synthesis gas at Cemex’s cement plant in Alicante, Spain. The Clyngas project, cataloged as “the first of its kind” for the cement industry by the EU, has the potential to reduce over 400,000 tons of CO2 equivalent emissions over a decade at the Alicante plant.
