Development prospects for resource utilization of waste plastics

The development of waste plastic recycling technology is significant for protecting biodiversity, maintaining soil fertility, protecting the environment, and saving resources. This chapter explains the urgency of developing this technology and summarizes domestic and foreign plastic governance policies. It also puts forward improvement measures from technology, government-enterprise cooperation, and public education. Finally, existing problems of this technology, such as insufficient basic theory, corrosion of reaction systems, and deactivation of catalysts, are explained. In the future, we can comprehensively study the flow and heat transfer laws of supercritical water, establish a visual testing system, design a new efficient reaction system, and innovate management mechanisms. This technology will achieve large-scale industrial applications in the near future.
