Development of enzymatic depolymerization processes (multilayer packaging, post-consumer PET trays/clamshells, microplastics from wastewater treatment plants) and of immobilized enzymes for application in biofilter.
A pre-treatment process will ensure the improved accessibility to enzymes in multilayer packaging. For all three depolymerization approaches, an enzymatic degradation will be elaborated and lead to a degradation of multilayer packaging consisting of PET and polyolefin layers, PET- trays/clamshells and microplastics, containing PET and polyolefins. The breakdown products will be further characterized. For the microplastic degradation in particular, an immobilization of enzymes will be necessary in order to realize a biofilter application.
