| Abstract | The indiscriminate use of plastics and careless management of plastic waste have caused serious environmental challenges globally. The Republic of Korea (ROK) aims to address the issue by reducing plastic waste generation by up to 50%, and increasing recycling rate by up to 70%, by 2030. To determine the status and future directions for plastic waste management in the ROK, the present study undertook two tasks: (i) a material flow analysis of plastic waste material from industrial sectors to assess the current status of plastic waste recycling and treatment, (ii) an analysis of the material flow of plastic waste based on the "Waste Classification Code." According to the findings, 6.202 million metric tons of plastic waste were generated in 2018, out of which 69%, 25%, and 0.5% was recycled, incinerated, and landfilled, respectively. The recycling rate of synthetic resin waste, which accounts for 96% of synthetic waste polymers discharged in the industrial sector, was 69%, which is a very high rate. However, the closed-loop recycling rate was only 33%. Therefore, the system of management of synthetic resin waste discharge without classification of raw materials should be improved to increase the closed-loop recycling rate of synthetic waste polymers. Furthermore, to increase the closed-loop recycling rate, we suggest the subdivision of synthetic resin waste (51-03-01) in plastic waste classification to improve the discharge separation system, which has been mismanaged. Furthermore, we suggest the formulation of a new management strategy for plastic waste, in accordance with those of other hazardous substances, as regulated by the Waste Control Act. |
