Decarbonizing the products we use every day by turning waste CO₂ into valuable molecules, powered by renewables

The world has begun to electrify its energy systems but not its molecules. Every battery, wind turbine, and solar panel still hides a paradox: about 80% of the materials that build our modern life like plastics, perfumes, coatings, medicines, explosives, come from fossil hydrocarbons. And above 90% of those molecules are imported into Europe.

This dependency isn’t just unsustainable. It’s a strategic weakness.

At ReMoléculaire, sustainability isn’t just a goal, it’s our essence. Our mission is to craft cutting-edge, high-performance molecules that power the shift from fossil dependence to circular chemistry. By transforming carbon dioxide into new value, we’re reimagining the foundation of industry and shaping a world where progress and the planet thrive together.

Converting CO₂ into High-Value Chemicals and Materials

Our process uses electricity and waste CO₂ to make acetylene (C₂H₂), a compact, energy-dense molecule that serves as a clean building block for countless chemicals.

At the heart of the system is our electrochemical reactor, which uses renewable power to break down CO₂ and reassemble its carbon and oxygen atoms into new molecules. The process runs at ambient temperature and pressure, making it far safer and more efficient than traditional high-temperature fossil routes.

Each modular unit includes:

  • CO₂ preparation: The incoming CO₂ is cleaned and conditioned for the reaction.

  • Electrochemical cells: Inside, special catalysts and membranes drive the precise conversion of CO₂ into C₂ compounds like acetylene.

  • Product purification: The acetylene is then separated and refined to polymer-grade purity, ready for downstream use.

  • Energy recovery loop: Heat and gases are continuously recycled, minimizing waste and water use.

Because each reactor is containerized and modular, capacity can be expanded simply by adding more units. The result is a continuous, emission-free process that replaces fossil feedstocks with renewable carbon, redefining how the world produces its essential molecules.
