In the present work, the energy recovery and the mechanical recycling, i.e. two treatment options forplastic wastes from the discarded TV sets have been assessed and compared in the context of the life cycleassessment methodology (LCA). The environmental impact of each option was assessed by calculatingthe following impact indicators: energy depletion (ED), depletion of abiotic resources (ADP), and global warming potential (GWP). Then, the indicators were compared and the option with the smallerenvironmental impact was selected. The main finding of this study was that mechanical recycling ofplastics is more attractive treatment option in environmental terms than incineration for energy recovery.
