Triboelectric nanogenerators (TENGs) hold immense potential as sustainable energy sources, with waste materials serving as promising materials for their fabrication. Nearly 270 million tons of waste is produced yearly, most of which remains unrecycled. TENGs can utilize this wide range of waste to convert mechanical energy to electrical energy while providing a solution for the global issue of plastic waste. On the other hand, the enormous demand for wearable electronics and the Internet of Things (IoT) trigger the development of self‐reliant energy sources. Currently, TENGs are one of the preferred choices as they are easy to design and generate high output. In this regard, TENGs are promising for utilizing waste materials, particularly for self‐powered or energy‐autonomous applications. This review focuses on utilizing waste materials from diverse sources, including biowaste, household waste, medical, laboratory, pharmaceutical, textile, electronic waste (e‐waste), and automotive waste for TENG development. Different waste materials are detailed for their potential as materials for TENGs, their availability, and recycling methods. The review also highlights the applications of TENGs fabricated from waste materials. Finally, the challenges, limitations, and future perspectives of using waste materials for TENG fabrication are discussed to motivate further advances.

The emergence of wearable electronics in contemporary lifestyles has spurred the need for smart fabrics capable of harnessing biomechanical energy. In the present study, a flexible polyaniline‐doped textile‐based triboelectric nanogenerator (PT‐TENG) is designed to harvest low‐frequency mechanical vibrations and convert them into electricity. For the device fabrication, five different textile fabrics are doped with conducting PANI, which is utilized as the tribopositive material, PVC thin film as the tribonegative material, and Al foil as electrodes. The PT‐TENG works in vertical‐contact separation mode, devised in arch structure for easy and complete contact between the working layers. Interestingly, the device featuring a PANI‐doped silk fabric generated the highest output voltage of 257.68 V and a current of 5.36 μA, respectively. Additionally, the PT‐TENG exhibits mechanical durability and electrical stability during continuous 7000 cyclic operations. Furthermore, the PT‐TENG showcases practical applications such as charging commercial capacitors, powering green LEDs and smartwatches, and as a self‐powered touch sensor. Thus, the PT‐TENG offers a facile fabrication process and robustness, highlighting its potential for sustainable energy harvesting in wearable electronics.

The widespread adoption of electronic devices has led to a dramatic increase in electronic waste (e‐waste), posing significant environmental, human health, economic, and data security concerns while also exacerbating landfill waste. Effective e‐waste management strategies are crucial for maintaining a sustainable planet. This article explores the upcycling of e‐waste using triboelectric nanogenerator (TENG) technology for electricity generation. Specifically, with straightforward procedures, the organic photoconductor (OPC) drum from printer cartridge waste is modified and incorporated as the positive triboelectric layer in the present TENG design. The fabricated OPC‐TENG, featuring the OPC drum sheet and fluorinated ethylene propylene (FEP) pair, exhibits promising performance metrics: an open‐circuit voltage of ≈492 V, a short‐circuit current of 138 μA, and a power density of 4.6 W m−2. Moreover, its capability to continuously operate digital watch and calculator with an integrated energy management circuit is demonstrated. The simplicity of the fabrication process, coupled with the significant energy output of the device, underscores its potential for self‐powered applications. These findings highlight a pathway towards harnessing e‐waste for sustainable energy production and revolutionizing e‐waste management, contributing to a greener and more energy‐efficient future.
