Thermal-biological waste recycling

The SEG process is a fluidized bed gasification process for the production of a high-quality synthesis gas with in-situ CO₂ capture using CaO/CaCO₃ as the active bed material. In this process, the synthesis gas composition can be tailored with regard to its content of CO, CO₂ and H₂ by changing the gasification temperature. The SEG process is therefore particularly suitable for downstream valorization processes.

The project is further developing the method so that the technology can be used for the gasification of waste materials. In addition, it will be demonstrated how the synthesis gases produced in the process can be further processed into valuable materials, e.g., short-chain alcohols and organic acids, through microbial valorization.
