초록
Different eco-friendly buoys composed of materials, such as Polyethylene (PE), Polypropylene (PP), polyethylene tereph-thalate(PET), are used as a countermeasure for marine pollution issues of Styrofoam buoys. However, fragmented microplastics con-tinue to persist without fundamental material conversion. Currently, the most commonly used eco-friendly buoy is composed of ther-moplastic, which adversely affects the seawater ecosystem owing to the generation of refractory plastic. To address this issue, in this study, a biodegradable material was developed for buoys that minimizes the generation of microplastics, and a material property test based on ASTM D638 was conducted to determine the strength of the biodegradable material. In addition, to evaluate the impact-resistance performance satisfaction of buoys specified in the eco-friendly buoy certification standard, the optimal thickness of eco-friendly buoys was estimated by generating a buoy model, applying the physical properties of development materials and analyzing the impact through the free drop of the EPP.
