In the “Circular Foam” project, old refrigerators containing high-grade plastics are to be converted into new raw materials for the chemical industry.
A consortium from nine European countries wants in future to upcycle valuable plastic waste: In the “Circular Foam” project, old refrigerators or façade elements containing high-grade plastics are to be converted into new raw materials for the chemical industry. Among the 22 partners from research and industry involved are Professor Sebastian Engell, Professor for Process Dynamics and Operations at the Department of Biochemical and Chemical Engineering of TU Dortmund University, and his team. Professor Engell was involved in planning the project and will lead a work package.

If Europe wants to become the world’s first climate-neutral continent by 2050, it will be necessary, among other things, to develop innovative recycling solutions. This is where the new project comes in: The consortium will develop a concept that shows how waste containing high-grade plastics can be converted into valuable products. Specifically, this involves rigid polyurethane (PU) foams from insulation in refrigerators and building components, which are to be converted into raw materials for PU production in a resource-friendly way. Here, the aim is to use processes such as chemolysis and intelligent pyrolysis. The consortium will examine the entire material flow chain – from the collection of the waste to its sorting, separation and treatment, to further chemical processing and feeding into existing production processes.
