## About Cyclize

Cyclize is a German climate-tech and deep-tech startup that originated from the University of Stuttgart.

The company focuses on defossilizing the chemical industry by converting mixed plastic waste and CO2 into syngas, a valuable feedstock for chemical production. Cyclize aims to provide a circular-carbon feedstock solution, replacing fossil-based inputs like natural gas with waste-derived and CO2-derived carbon sources. Using a proprietary plasma-based process, Cyclize transforms difficult-to-recycle waste streams and industrial CO2 emissions into high-quality syngas. This syngas can be integrated into existing industrial value chains and is suitable for producing plastics, methanol, hydrogen, and e-fuels. Additionally, Cyclize builds and operates chemical plants, offering tailored test series for waste streams currently being incinerated, including validation of feedstock composition and syngas quality. The company primarily serves chemical producers and industrial customers looking to decarbonize their operations.
