About
-
Compositional analysis of multilayer flexible packaging types (PET/PLA/PE, PET/EVOH, PLA/PBAT). Layer-specific recalcitrance assessment
-
Enzyme screening and optimization for layer-selective depolymerization. Focus on PET and PLA layers within multilayer structures
-
Proof-of-concept deconstruction under relevant packaging conditions. Monomer recovery and purity assessment
-
Engineering of microbial pathways for monomer upcycling. PLA-derived and PET-derived carbon sources toward glutaric acid, adipic acid, and muconic acid
-
Lab-scale fermentation and downstream processing
-
SSbD assessment, LCA and TEA. Environmental performance benchmarked against incineration and landfill. Regulatory considerations for food contact material contexts
