Synthetic polymers offer many conveniences to modern life, but also pose a waste problem that is difficult to decompose. Over 90% of marine debris is plastic; because of its persistence, its impact on oceans, wildlife and people is increasing over time. This includes the degradation of marine environmental ecosystems, the obstruction of ships by garbage, the havoc of coastal and seabed debris on tourism and fishing, and the burden on coastal communities that depend on the ocean for their livelihoods. This research will realize on-site waste treatment, reduce transportation energy consumption, meet regional energy demands, and reduce carbon emissions from long-distance transportation. For coastal waste, river blockage, fishing port and scenic spot waste, there are immediate benefits of specific reduction and elimination. In addition, we can use the technology in this paper in the replacement of wind turbines, because the composition of the wind turbine blades is composite materials. This application can dispose of decommissioned blades on the spot, reduce transportation costs, and provide a reliable solution to replace the current problem that blades are difficult to recycle.
