Thiswork has asmain objective the analysis of waste from electric and electronic equipment (WEEE or e-waste) management through material flow analysis and life cycle assessment of a full-scale Italian facility that is significant about the e-waste flows treated (9900 t/y) and representative of a developed EU country about the industrial process outline, based on manual dismantling phases and physic-mechanical automatic processes. Three WEEE categories (i.e. R1-Cooling equipment, R2-Large household appliances and R3- TVs and screens) have been chosen with the reason that they are the most abundant in EU. The methodology was based on two endof- life scenarios: S0-partial recycling of valuable fractions and landfilling of the rest, which is conventional ewaste processing in Italian facilities; S1-complete recycling of valuable fractions, limited incineration and landfilling of the rest, which describes what happens in the considered case study. Mass balance of the three treatment lines showed recycling rate (RR) values equal to: for R1 40% for S0 and 80% for S1; for R2 65% for S0 and 99% for S1; for R3 86% for S0 and 91% for S1, with significant fractions incinerated or landfilled only for R1 treatment line. Life cycle assessment considered transport (post-consumer collection), treatment, recycling, incineration and disposal. As main results, eco-toxicity aquatic potentials referring to marine and fresh water were themost relevant impact categories. In conclusion, recycling (mostly ofmetals) played a crucial role for environmental benefits, and transport and polyurethane plus rubber incineration for the environmental impacts.
