“…66 Therefore, they developed a microbially driven Fenton process to accelerate the degradation and removal of MPs in the composting system by adding iron oxides to the compost to generate •OH spontaneously. 67 Their results showed that the process was able to remove 35.93% of polyethylene microplastics within 36 days of treatment. Although the removal efficiency is still low compared to other methods, the removal efficiency of this The results of GC-MS showed that there were more than 10 kinds of short chain organic compounds in the degradation liquid.…”

The existence of waste plastics and microplastics has caused serious pollution to the ecological environment. Harsh reaction conditions or long reaction time are typically required for the current waste plastic treatment technologies, resulting in high energy consumption and capital cost. Recently, plasma, Fenton, and electrochemical technologies have emerged to upcycle waste plastics under mild conditions and remove microplastics efficiently. The fundamentals and applications of plasma, Fenton, and electrochemical technologies in waste plastic treatment are reviewed. The prospects of these emerging technologies are also discussed, aiming to provide the scientific background, application status, and technical challenges for these emerging technologies for waste plastic treatment.
