With nearly 20 years of experience in the field, Dr. Um has been a public researcher for the National Institute of Environmental Research, where he specializes in waste management engineering and contributes to building a new policy framework with strategic environmental assessment for effective waste management in Korea, since 2013. Prior to that, he was with the Korea Institute of Geoscience and Mineral Resources as an assistant scientist from 2005 to 2009, and as an associate scientist from 2009 to 2013. His work on a number of national projects included development of recycling technology of wastes for civil engineering and construction material by integrated management system.
The coal ash (CA) generated from coal-fired power plants (CPPs) is collected in ash ponds (APs), most of which are actually full, so there are concerns regarding the potential contamination of the environment around them. Thus, in the present study, a method for improving the utilization of coal pond ash (CPA) was proposed. Here the CA landfilled in an AP was regarded as CPA. Furthermore, the CPA characteristics (particle size and weight distributions, chemical composition, unburned carbon (UC) content, particle image, and mineralogical analysis) were investigated. Next, experiments were conducted on the main separation processes: screening with five standard sieves having 0.15-, 0.3-, 0.6-, 1.18-, and 2.36-mm diameter grids; float–sink experiments with four different specific gravities (SGs) of under 1.8 SG, 1.8–2.2 SG, and 2.2–2.5 SG and over 2.5 SG; flotation with a column-type glass reactor under the conditions of pH 2, 7, and 12; grinding with a batch-type ball mill for 5, 10, 20, and 40 min; wet magnetic separation with four magnetic forces (0.1, 0.5, 1, and 2 T). Based on these results, a pretreatment method was proposed and the final materials could be categorized into UC, amorphous compounds (ACs) with Al species (Al2O3∙xH2O) and glassy phases, inorganic materials with Si and Al, and ferrous material groups. Besides, six additional pretreatment methods were suggested through various combinations of each separation process. As a case of South Korea, the applicability of this method to the entire CPA in South Korea was also confirmed.

In South Korea, the manufacturing system from chalcopyrite (CuFeS2) to Cu products is divided into two parts: electrolytic Cu manufacturing and Cu product manufacturing (CPM). Most of the CPM waste is deposited in landfills unlike the waste generated in electrolytic Cu manufacturing that has a good recycling ability. Therefore, in this study, a method to improve the utilization of CPM waste was proposed as a case study for South Korea. Furthermore, the CPM was investigated and classified into five types in terms of the raw materials, major products, additives, main processes, and characteristics of the CPM waste (waste type, particle size, and chemical composition). Next, the CPM waste was environmentally assessed via leaching toxicity tests using the Korean standard official method, ES 06150. In addition, the amount of specific heavy metals (Pb, Cu, Cd, As, Hg, and Cr6+) was determined to confirm the presence of substances labeled as hazardous waste. Based on these results, a pretreatment method with grinding (under 0.1 mm), screening (0.15 mm grid), magnetic separation (1.0 T), and alkali leaching (30–90 °C and 1–5 mol/dm3) was proposed. The final materials can be categorized into groups, such as fine-particle groups with high Zn and Fe contents, leachate groups with high Cu and Zn concentrations, and metal-scrap groups. Moreover, material flow analysis of all CPM waste streams in the designed pretreatment method was conducted in South Korea in 2019.

With an increasing use of plastic, considerable plastic waste is generated, threatening the environment and public health. In particular, changes in living patterns in urban areas have significantly impacted the rate at which plastic waste increases every year. Thus, governments in many developed countries have implemented numerous policies to reduce plastic waste generation. Among them is the concept of circular economy that aims to protect the environment from plastic pollution and promote growth and innovation in industry and human life through overall changes in designing, producing, using, and recycling plastic products. The Korean government has implemented the Resource Circulation Act (RCA), which includes the concept of circular economy and resource efficiency policy for overall waste management. Following the concept of RCA, the Plastic Waste Control Plan (PWCP) was established for the comprehensive management of plastic waste. Therefore, this study introduces the goals and strategies of PWCP, which has a circulation system of four stages of production, consumption, discharge, and recycling, as well as the major roadblocks in the stages impeding the achievement of the goals and strategies. This study also suggests countermeasures at the government level for solving the major problems in the four stages.

In this study, the effect of Cl removal in bottom ash via a carbonation treatment with CO2 was investigated by comparing it with a water washing treatment. First, this was also focused on examining the existence of Cl contained in the bottom ash. The overall (soluble and insoluble) Cl content was close to that of bottom ash with fine particle. Next, the washing with water was confirmed and it was not effective in decreasing the Cl content because of the existence of insoluble Cl. Whereas, the removal effect of Cl via carbonation with CO2 was very high compared to the washing treatment because of the decomposition of Friedel’s salt (main insoluble Cl). In addition, the kinetics data pertaining to the decomposed Friedel’s salt as the carbonation process proceeds was confirmed. The theoretical was well fitted to the kinetics data. The variation of the rate is constant upon decomposition with the reaction temperature followed the Arrhenius equation (19.676 kJ/mol of activation energy) and the orders with respect to water-to-solution and particle size were also obtained. The decomposition rate of Friedel’s salt based on diffusion through the product layer of shrinking core model could be expressed by the equation.

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.

In the development of mines, risk is latent in a variety of areas. Thus a feasibility study was conducted to determine certain risks. In particular, mineral processing for the recovery of a target mineral constitutes a very large percentage of the cost from the start of a project, and it is an important step in relation to the recovery of funds. In this study, a feasibility study of molybdenum mineral processing is done and comparisons are made between a pilot plant and a commercial plant using the LCCA evaluation method. At the pilot plant, the NPV value of a deterministic approach at five years is $68,984 and the probability that the NPV exceeds 0 is 58.23% according to Monte Carlo simulation done using a probabilistic approach. At the commercial plant, the NPV value with the deterministic approach at five years is –$10,820,473, and it was found that the probability of NPV according to deterministic estimation is 49.91% in a Monte Carlo simulation. As a result, the commercial plant is evaluated as experiencing a loss due to a decrease in the molybdenum concentrate price, whereas a price increase of 20% relative to the current molybdenum concentrate price can meet the margin after five years when the NPV exceeds over 0.

The dissolution behavior of CeO2 in sulfuric acid was examined using a batch reactor with various acid concentrations (8–14 M) at different temperatures (75–130°C). The dissolution of CeO2 was slow and it took more than 3 days to dissolve 4 mmol of a CeO2 powder completely in 100 mL of 12 M sulfuric acid at 90°C. The dissolution rate increased with increases in the temperature and the sulfuric acid concentration. The dissolution rate could be expressed by a shrinking sphere kinetics model. The variation of the dissolution rate constant with temperature obeyed the Arrhenius equation with the activation energy of 120 kJ mol−1. The reaction rate constant was a function of the acid concentration as C6.5.

A coal ash generated from a coal-fired power plant largely divided into fly ash and bottom ash. All of the coal fly ash has been recycled and the coal bottom ash (CBA) in only a part restricted within narrow field. But, many researchers have investigated the study about recycling of CBA by physical separation because it has various materials such as silicate, aluminate, unburned carbon and magnetic-substance. For example, it is easy to be removed by magnetic separation in the case of magnetic-substance contained in CBA. Thus, we investigated the recovery of ferromagnetic material by wet magnetic separation in CBA. For this study, we researched the recovery rate of ferromagnetic material, such as iron and magnetite through wet magnetic separator at various magnetic forces and confirmed the distribution of ferromagnetic material as a various particle size.

Municipal solid waste incineration(MSWI) bottom ash consists of glassy materials, ceramics, ferrous materials mainly. Therefore, in some European countries, it is used as construction material. But, the bottom ash is more considered as a chemically reactive material that releases hazardous heavy metals. In order to manage the bottom ash, understanding of the carbonation process is necessary. Because their influence on carbonation reaction in bottom ash may has a significant effect on the leaching characteristics of contaminants such as heavy metals. To gain a proper appreciation of the carbonation role of mineral constituent in bottom ash, it is essential to understand the relationships between their morphology, composition and their influence on carbonation reaction. Therefore, we carried out the study on mineral constituent of bottom ash and their influence on carbonation reaction.
