An improved strategy for effectively managing the transboundary movement of waste based on the basel convention: A case study in South Korea.

Despite the efforts made to minimize the illegal trafficking of hazardous waste and prevent environmental pollution worldwide in accordance with the 1989 Basel Convention (BC), the illegal transboundary movement of waste and associated environmental pollution are ongoing. This study proposes a three-stage theoretical approach to effectively managing this waste. In stage one, the Convention, including its 2019 revisions, stipulates six primary requirements: clear declaration, hazardous waste, onsite inspection, responsibility, transport management, and final disposal after import. In stage two, the export and import management system is divided into four facets: customs preprocessing, customs processing, follow-up, and law. The challenges are presented of how to align the waste disposal with the Basel Convention's main requirements. Stage three presents a discussion of the effectiveness of the countermeasures derived in stage two for disposing of waste both within individual nations and internationally. Then, the theoretical approach was applied to analyzing South Korea Ministry of Environment's Act on the Transboundary Movement of Hazardous Waste and Their Disposal (revised in 2017). The strategy was demonstrated to be an improvement, and these study results can be foundational data to newly establish laws or revise existing acts on transboundary movement of waste (TMW) in each country.

Application of material flow analysis for plastic waste management in the Republic of Korea.

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.

Strategic environmental assessment for effective waste management in Korea: A review of the new policy framework.

This study examines the new policy framework, which includes effective environmental assessment procedure to manage waste in Korea. Concept of this framework pursues the important strategies toward the waste reduction, preservation of landfill area, stabilization and removal of hazardous substance in wastes, and optimal treatment for energy and material recovery from wastes. Therefore, it has begun on three points. First, activating the effective recycling system to reuse wastes will be essential to waste reduction. Second, the utilization of substitute resource can be expected through the optimal transforming the wastes into the recycled product, raw material, thermal energy, etc. Third, the characteristics of waste must be evaluated by strategic environmental assessment. To realize this concept, the strategic environment assessment with reinforcement of hazardous property, categorization of recycling type, and classification of environmental assessment procedure depending on the recycling type was provided. In addition, based on this environment assessment, the new policy framework was built through the established and revised Wastes Control Act by focusing on simple systematic procedure for decision of the possible recycling and strengthening the safety of the wastes to a higher level with promoting recycling activities.
