초록
The use of polystyrene (EPS) in ocean farming has recently changed to eco-friendly materials such as polyethylene (PE) and polypropylene (PP). However, despite this shift, PE and PP still contribute to microplastic generation owing to their vulnerability in marine environmental conditions and potential collisions with ships. Fragmented micro-plastics continue to occur due to the use of plastic materials without fundamental material conversion. Therefore, the development of an ocean farming buoys utilizing biode-gradable materials such as polylactic acid (PLA) is in progress. As biodegradable materials have higher density than existing PPs and PEs, buoys crafted from PLA are heavier than those made from conventional materials. Accordingly, the buoys may sink and the buoyancy or productivity of farmed organisms may decrease. Therefore, in this study through hydrodynamic diffraction and response analysis, a weight of PP, PE, or PLA was applied to each buoy, and the kelp weight was assigned and compared to each buoy for analysis.
