Stuttgart-based deep-tech startup Cyclize is working to replace fossil natural gas in chemical production. Dr. Klaus Schäfer, Covestro’s former CTO, became Cyclize’s Chief Industrialization Officer on October 1, 2026. An investor and Advisory Board Chairman since 2024, he will lead technology integration in European chemical parks while retaining his board role.

P2M2X focuses on developing a novel plasma-membrane reactor that integrates CO₂ splitting and oxygen separation within a single system.

Cyclize GmbH is a partner in the 36-month European project BioH2Steel, funded by the BMWK. The initiative investigates replacing fossil natural gas with biogenic, hydrogen-rich syngas from waste streams for the Direct Reduction of Iron (DRI). Cyclize will deploy plasma-based gas conditioning to remove tars and impurities, ensuring industrial-grade syngas quality. The project further explores Carbon Capture and Utilization (CCU) to enhance circularity in energy-intensive primary industries.

Cyclize has won the 2025 Stuttgart Innovation Award for its plasma-based chemical recycling technology, which enables the chemical industry to replace fossil feedstocks by converting non-recyclable waste into circular carbon and reducing CO₂ emissions.

Cyclize has been selected as a winner of the Startup Challenge Schwedt and will implement a 3,000-hour plasma reformer pilot at the Schwedt industrial site to demonstrate circular, defossilised syngas production from CO₂ and local waste streams in collaboration with PCK Raffinerie, VERBIO and Griesemann Engineering.

ClimateTech start-up Cyclize raised €4.75 million in seed funding to revolutionize the chemical industry with a plasma-based process that turns mixed plastic waste and CO₂ into climate-friendly synthesis gas, replacing fossil resources and enabling true circular carbon economy.

EXIST research transfer funding approved for Cyclize for the development of non-fossil carbon feedstock for the chemical industry.

In an interview with Perspektiven, the magazine of the Baden-Badener Unternehmensgespräche (BBUG), Cyclize CEO Maike Lambarth and KfW CEO Stefan B. Wintels discuss the transformation of the chemical industry, carbon circularity, and the need for planning certainty and risk capital to scale climate technologies.

In Carl – Die Zukunft der Labore ist Roth, the Stuttgart-based start-up Cyclize is featured for its plasma-based technology that converts plastic waste and CO₂ into synthesis gas, enabling the chemical industry to replace fossil feedstocks while advancing a circular and climate-compatible use of carbon.

Magazine CHEManager interviewed two of the four founders of Cyclize. They gave an overview on the idea and their start-up journey.

In Innovation Chemie Pharma, Cyclize is featured for its plasma-based technology that enables the chemical industry to replace fossil natural gas with mixed plastic waste and captured CO₂, closing the carbon loop while supporting industrial defossilization.

Cyclize’s innovative plasma technology was highlighted on Lesch’s Kosmos in 2022, bringing national visibility to its approach for converting plastic waste and CO₂ into synthesis gas: a key step toward a circular carbon economy. The broadcast showcased the potential of circular solutions to industrial carbon challenges to a broad audience.
