영문 초록

The total amount of oyster shells produced annually in South Korea is estimated to be about 280,000 tons. Of them, 180,000 tons are being recycled as materials for oyster or Porphyra seed collection, shell fertilizers, and treated by contracted waste management companies. The rest, 100,000 tons, are illegally disposed of at farm sites or near the business facilities, causing severe environmental problems such as pollution of coastal fishing grounds, destruction of the landscape, and disturbance in the management of public waters. Multiple dumping methods of oyster shells comprise restoration measures that utilize unprocessed oyster shells to restore the sand mining zone within the South Sea of the Korean peninsula’s exclusive economic zone (EEZ). On that note, this study aims to conduct primary research to calculate the range of diffusion effects of each dumping method of oyster shells. Accordingly, the researchers collected unprocessed oyster shells from five oyster shucking fields near the South coast three in Tongyeong, one in Geoje, and one in Goseong, and measured the settling velocity by the respective size of the oyster shells in a hydraulic experiment. In addition, the diffusion distance of each dumping method was calculated by using a Computational Fluid Dynamics (CFD).
