Revolutionizing waste-to-energy: harnessing the power of triboelectric nanogenerators

Abstract

Recently, there has been a lot of focus on developing new waste-to-energy technologies because they help us to provide sustainable energy solutions for future generations. This review paper investigates an innovative waste-to-energy technology known as triboelectric nanogenerators (TENGs), which uses the electrostatic induction and contact electrification principles of physics. The underlying physics of TENG technology allows for a wide range of material choices for its fabrication; as a result, waste materials are utilized for energy production using TENGs. It comprehensively discusses how various types of waste, including plastic, electronic, medical, household, and biowaste, can be integrated into TENG technology for efficient energy production. Furthermore, various applications of waste-based TENGs are discussed in detail. Finally, we projected challenges and future directions for creating a sustainable, green energy landscape. The review article presents a detailed exploration of triboelectric nanogenerators (TENGs) as novel waste-to-energy technologies that utilize waste materials.
