The composition of plastic and multilayer packaging waste was assessed in the mixed municipal solid (MSW) streams Kaunas (Lithuania), Daugavpils (Latvia) Tallinn (Estonia) municipalities. For analysis samples MSW streams, authors used manual sorting a visual recognition method. Composition from separately collected multi-family single-family households performed research group combined near-infrared (NIR) spectroscopy methods. findings reveal that percentage distribution within stream is relatively consistent across municipalities Kaunas, Tallinn, comprising 40.16%, 36.83% 35.09%, respectively. However, notable variation emerges when examining streams. In this category, proportion total ranges 62.05% to 74.7% for residential buildings 44.66% 56.89% buildings. provided further insights enhanced recycling potential different materials through improved sorting.

Multilayer plastic films (MPFs) are widely used in the food industry. Despite its widespread use, recycling of MPF remains a challenge due to complex structure. Solvent-based is more and costly than conventional mechanical recycling, which most method despite technical economic limitations. This study investigates post-consumer without separating constituent layers. Samples were prepared using thermal extrusion cycle with control temperature, speed sample size improve melt state, homogeneity response mixture. The results physicomechanical characterization this research show that proper selection parameters for fine multilayer waste 2 mm particle size, has positive impact, instance, on final maximum strength recycled material, demonstrating an increase up 40 70% tensile flexural properties, respectively. proposed separation constituents can produce material properties comparable those low-density polyethylene polypropylene. These findings could significantly benefit industry by reducing pollution allowing creating new products specific tailored different applications.
