Platform for optimizing and testing the pyrolysis process on an industrial scale.

The “Circular Carbon Technologies” working group develops processes and technologies on an industrial scale that ensure the low-CO2-emission material use of primary and secondary carbon sources that were previously only used thermally.

By reintroducing carbon into the value chain through chemical recycling, the carbon cycle can be closed. At the same time, the economically competitive production of mass products (e.g. basic chemicals, plastics) and high-priced special products (e.g. carbon fibers, extraction materials) based on domestic carbon sources, including residual materials with the broadest possible quality spectrum, should be made possible.
