This review paper focuses on the innovative waste-to-energy technology known as triboelectric nanogenerators (TENGs), which leverages electrostatic induction and contact electrification principles. TENGs offer a versatile approach to energy production using various waste materials, including plastic, electronic, medical, household, and biowaste. The paper discusses the integration of these waste materials into TENG technology for efficient energy generation and explores various applications of waste-based TENGs. It also addresses the challenges and future directions for creating a sustainable, green energy landscape. The authors emphasize the importance of WTE technologies in achieving the United Nations' Sustainable Development Goals (SDGs), particularly in ensuring sustainable consumption and production patterns and access to affordable, reliable, and sustainable energy. The review highlights the interconnectedness of these goals and the potential of WTE technologies to reduce environmental impact, promote economic growth, and support a circular economy.This review paper focuses on the innovative waste-to-energy technology known as triboelectric nanogenerators (TENGs), which leverages electrostatic induction and contact electrification principles.
