Abstract

The rapid rise in electronic waste (e-waste) necessitates sustainable energy and waste valorization strategies. This study presents an e-waste-based triboelectric nanogenerator (EW-TENG) using upcycled components, aluminium electrolytic capacitors, Metallized Polypropylene Self-Healing (MPP-SH) capacitors, and lithium/zinc-ion batteries. Classified as film or powder-based, these materials were integrated with polyvinyl alcohol (PVA) to form composite films, serving as tribopositive layers against polyvinylidene fluoride (PVDF) in a vertical contact-separation mode. Aluminium (Al) foil and recycled polyethylene terephthalate (PET) were used as electrodes and substrate, respectively. The optimized EW-TENG produced an output of 274.40 V, 12.32 μA, and a peak power of 144.30 mW at 130 MΩ. It successfully powered 70 LEDs and a digital wristwatch, and also operated as a liquid-level sensor via a floating electrode mechanism. This multifunctional device offers a sustainable, low-cost solution for energy harvesting and sensing, highlighting the potential of e-waste in powering household, industrial, and agricultural applications.
