Small waste from electrical and electronic equipment (WEEE) such as mobile phones are rich in plastic components. Recycling is particularly challenging, since the main interest for recyclers printed circuit boards, valuable metals, while components usually destined thermal recovery. This study dedicated to assessment of recyclability potential fractions end-of-life (EoL) according European Union’s (EU) Restriction Hazardous Substances (RoHS) Registration, Evaluation, Authorization Chemicals (REACH) directives.

The rapid accumulation of polymer waste presents a significant environmental challenge, necessitating innovative management and resource recovery strategies. This study investigates the potential chemical recycling via pyrolysis plastic waste, specifically polystyrene (PS) polypropylene (PP), to produce high-quality pyrolytic oils (WPPOs) for use as alternative fuels. physicochemical properties these were analyzed, their performance in gas turbine engine was evaluated. results show that WPPOs increase NOx emissions by 61% PSO 26% PPO, while CO rise 25% PSO. Exhaust temperatures 12.2% 8.7% PPO. Thrust-specific fuel consumption (TSFC) decreases 13.8% with negligible changes environmental-economic analysis indicates using WPPO 68.2% impact PS100 64% PP100, energy emission indexes rising 101% 57.8% compared JET A. Although reduces costs 15%, it significantly elevates CO2, CO, NOx. research advances understanding integrating into systems, promoting circular economy balancing challenges.
