In order to activate the recycling of hazardous wastes, the hazardous characteristics of wastes should be removed or stabilized. However, most recyclers in recycling companies do not understand how to remove the hazardous characteristics in wastes with the proper technology. The aim of a new form of advanced management of hazardous waste is to inform recyclers and operators in industries about hazardous characteristics and the treatment methods required for all management processes, from waste generation to final treatment. In a new method of advanced management of hazardous wastes, chemicals in the waste should be initially examined at the generation source in each industry to create a chemical catalogue. Since hazardous characteristics can be determined by a chemical catalogue obtained from the waste, the hazardous characteristics of wastes can be established and considered when choosing the proper treatment method. Then, the categories of waste treatment methods for each hazardous characteristic can be introduced for generators to treat hazardous wastes properly. Therefore, it is possible to create a link between the source and the final treatment of hazardous wastes using a new concept of industry (In), waste (W), hazardous chemicals and their hazardous characteristics (Ha) and treatment methods (T). This new concept of the “InWhat” system, which includes all management processes in Korea, from waste generation to final treatment, will be proposed as a tool in the advanced management of hazardous wastes.

In light of the growing attention to the need for establishing a lifecycle-oriented circular economy and to promote resource circulation to maximize the utilization of limited resources, this paper presents a case study on setting-up new national-level indicators and targets in accordance to the shift in the national waste management paradigm from waste treatment to resource circulation, which is being initiated in multiple countries around the world. Specifically, using the case of Korea, which recently implemented its new Framework Act for Resource Circulation, this study illustrates the process for setting new indicators and projecting Korea’s waste management based on the indicators developed in this study. The five main indicators suggested are the final disposal rate, actual recycling rate, waste to energy recovery rate, resource circulation rate, and resource productivity, and their precise definitions and calculation methods and the necessary revision in national statistical data collection for obtaining the required data for the indicators are discussed. For the effective delivery of the policies in the long term, the annual targets for the indicators and overall strategies for promoting resource circulation are proposed based on the predictions for future population growth and waste generation. With continuous effort from 2018 to 2027, it is expected that Korea will be able to reduce its final disposal rate from 8.7% to 3.0% and increase its actual recycling rate from 76.4% to 82.0%, waste to energy recovery rate from 6.95% to 12.66%, resource circulation rate to 14.0% to 16.4%, and resource productivity to 630 USD/ton to 1900 USD/ton.
