Project description

In this project, the aim is to develop, demonstrate and compare three technologies for the conversion of plastic waste to liquid energy carriers and chemicals via (catalytic) pyrolysis. The first and second technology comprise a conventional fluidized or spouted bed reactor, whereas the third technology involves a new, disruptive reactor concept making use of rotating beds.

In the integrated approach of the problem, besides kinetic modeling and reactor engineering, focus will be given on the optimal feedstock selection to optimize individual yields of desired product(s) depending on the feed (thermosetting versus thermo-softening polymer). Plastic waste feeds of choice will be those streams that are currently not (mechanically) recycled but incinerated and/or dumped to landfill:

  • Mixed PE/PP/PS
  • Multilayer packaging
  • Waste PS
  • Polyurethane flexible and rigid foam

Next to the development of the reactor technologies, efforts will be made on the further catalytic upgrade of pyrolysis oil fraction, purification and separation of valuable compounds by advanced membrane separation processes, possibly in combination with liquid-liquid extraction. Ideally process intensification makes it possible to construct a plant on truck. A life cycle analysis (LCA) will be conducted to assess both technologies and downstream processing in terms of sustainability.
