Summary: Bioplastics have the potential to contribute to a more sustainable and circular economy by reducing carbon footprint and offering advantageous material properties. However, they also face challenges such as negative agricultural impacts, competition with food production, unclear end-of-life management, and higher costs. Emerging chemical and biological methods can enable the upcycling of plastic waste into higher-quality materials. Standardization and guidelines are needed to guide purchasing choices, and clear regulations and financial incentives are essential for the large-scale adoption of bioplastics in a truly sustainable manner.

Summary: Comprehensive views on dielectric loss mechanisms provide important guidance for understanding the attenuation behavior of materials. Current researches focus more on materials synthesis rather than in-depth mechanism study. Therefore, further research on in-depth mechanisms, emphasis on new dielectric loss mechanisms, and new modulation strategies are needed to achieve simple and effective EM wave attenuation behavior modulation.
