solvoPET - Developement of a recycling technology for (multi-layer) PET waste streams

The project solvoPET aims at developing a new chemical recycling technology for PET waste streams. Basis are inactive patents for the recycling of single-origin PET waste by solvolysis. Within the project, a new continuous recycling technology for multi-layer waste will be developed and experimentally tested. The goal is the recovery of the basic monomers terephthalic acid (PTA) and monoethylene glycol (MEG) by depolymerizing PET.

The technology is expected to be very versatile and can therefore be used to process inhomogeneous waste streams such as marine litter or post-consumer waste. During the project, the technology will be tested within a prototype plant and the acquired data will be used for the economical and ecological assessment.

The Institute for Machine Tools and Production Technology (IWF) is working together with the Institute for Chemical and Thermal Process Engineering (ICTV) of TU Braunschweig, the Fraunhofer Institute for Chemical Technology (ICT) and the following industry partners: Reclay Materials, Rittec Umwelttechnik, Schiller Apparatebau and VTU Engineering. The IWF is responsible for the overall assessment of the PET value chain and the recycling technology. Therefore, an economic and ecological assessment tool will be developed which is based on the data gathered in the prototype plant.

The Federal Ministry of Education and Research funds the project with a sum of approximately 1.2 Million Euros.
