on PET and their co-polymers
Scope: 30 hp
Location: RISE AB, Argongatan 30, Mölndal (south of Göteborg)
Are you interested in developing sustainable materials for the future, chemical recycling and a circular use of materials? Would you like to contribute to the development of processes that make more plastic recyclable? RISE is looking for a student with an interest in polymeric materials and their chemical recycling.
Project goal The aim of the diploma work is to build knowledge on how to chemically recycle vehicle interior design materials. New, more recyclable, design concepts for these materials comprise ‘one polymer solutions' based on PET and their copolymers. Initial results has shown that these PET based materials are suitable for chemical recycling via depolymerization. This diploma work will contribute with new basic research in the field of chemical recycling of PET copolymers and will be used for a future conference or scientific publication.
Background and purpose Recycling of plastics and use of recycled plastic is necessary in order to achieve a sustainable production and use of resources. This is part of the shift towards a circular economy which includes circular use of materials. The topic is relevant for the vehicle industry and Volvo Cars recently announced a strategy with the target of 25% recycled plastic in all cars from 2025. Interior vehicle components contains a lot of plastics and could be suitable as a source for recycled plastics. These interior components will, after vehicle fragmentation be part of the light shredder fraction of end-of-life vehicles (ELV) that today is incinerated or goes to landfill. This diploma work is a part of the research project Sustainable Vehicle Interior Solutions (SVIS) that is performed with financial support from the program Strategic Vehicle Research and Innovation (FFI). RISE together with Volvo Cars and a large number of companies within the automotive business are investigating the possibilities to find circular material loops and enable more use of recycled plastics and other materials in cars.
About the project The objective of this diploma work is to study the chemcial recyclability of PET and their co-polymers used in new, more recycable, interior designs for vehicles. To adapt existing car parts for future recycling schemes, “one polymer solutions” are advocated. For interior parts this can be done by utilising PET and PET bicomponent fibers and films (co-polymers of PET). The PET co-polymers add certain functionalities, such as adhesion or a lower processing temperature. Chemical recycling by depolymerisation of PET via glycolysis generate high value streams of PET monomers which can be repolymerized back to PET with virgin properties. However, less is known about the behaviour of PET co-polymers in chemical recycling with glycolysis. The aim for this master student work is therefore:
Who are you? For this degree project, the student should have a background in organic and polymer chemistry. Possible education programs include, but are not limited to, chemistry, chemical engineering, or other background with focus on material science.
The project will be performed at RISE Research Institutes of Sweden, in Mölndal, as part of a large research project involving Volvo Cars and a number of subcontractors.
