In the current daily life of people, the usage for disposable medical masks (DMMs) continues to be high. Discarded DMMs eventually become plastic pollution, threatening the marine environment seriously. At present, the common plastic recycling methods are extensive and not completely applicable for DMM recycling. In this work, according to the special structural and material characteristics of DMMs, a simple and effective recycling solution is proposed based on triboelectric nanogenerators (TENGs). First, a pulsed electric field system is designed and fabricated to treat the recycled films. The sterilizing rate reaches 91.8%, and the film surface potential is enhanced at the same time. Then, the feasibility of the treated films to be applied as the friction layers of TENGs is verified. Moreover, the recycled films are upgraded by chemical and physical methods, improving the output current of the basic TENG by 3.28 times. Finally, a complete TENG device is constructed to harvest water wave energy, 93.75% of which is made from recycled DMM materials. Under water waves, the power density of 18.22 W m−3 is achieved. Starting from TENG technology, this study combines circular economy and clean energy development, which is of significance for carbon neutralization.

Triboelectric nanogenerators (TENGs) have recently emerged as a promising technology for efficient water wave energy harvesting. However, there is a paucity of clear guidance regarding the optimal designs of TENGs and their shells to achieve efficient absorption and conversion of water wave energy in real random waves. Herein, from the perspective of wave‐body interaction and energy transfer, this paper proposes a structural quality factor (Qunit) for the quantitative evaluation of both the motion of floating triboelectric nanogenerator (Flo‐TENG) shells and their capability to absorb and convert water wave energy efficiently. The factor is further subdivided into the amplitude structural quality factor (Qacc), which characterizes shell motion amplitude, and the frequency structural quality factor (Qf), which describes shell motion frequency. This paper systematically investigates the impact of various shell parameters such as bow shapes, curvatures, inclinations, and immersion ratios on Qacc and Qf. The findings indicate that variations in shell shape result in distinct Qunit values along different axial directions of wave propagation. These variations directly influence energy absorption efficiency in these directions. These results provide fundamental guidance for the design of high‐performance Flo‐TENG shells and the selection of internal energy harvesting directions to enable more efficient energy conversion.

The challenging situations of growing energy consumption, waste collection and destruction of the surroundings had been made greater apparent by means of the explosive rise of the global population and commercial interest. Modern techniques based on the 5R principle (Recycle, Reduce, Reuse, Recover, and Repaired) are critical to efficaciously addressing these problems. One promising way to turn non-recyclable waste into beneficial power assets is waste-to-power (WtE) the conversion method. This work presents a comprehensive evaluation of various WtE technologies, consisting of pyrolysis, gasoline production, anaerobic digestion, and combustion, highlighting their ability to reduce waste associated troubles. Furthermore, as supplementary techniques for sustainable waste control methods, it seems at the combination of progressed waste control (IWM), higher landfill mining, and sustainable substances control (SSM). The impact on the environment of waste-to-power changes are evaluated through a radical evaluation of current research and technology advancements, emphasizing decreases in landfill utilization, GHG emissions, and the promoting of renewable energy resources. The consequences highlight the essential role that WtE generation performs in accomplishing power efficiency improvements, cleaner production, and the development of the round financial structure. Ultimately, the article makes suggestions for future studies initiatives and coverage recommendations intended to optimize the economic and environmental gains from WtE deployments.
