Plastic accounts for 60 ~ 80% of all marine litter. Microplastics are plastic pieces that are 5 mm or less in diameter. They can be classified into primary and secondary microplastics. Primary microplastics arise from the manufacturing, and secondary microplastics arise from plastic decomposition by various factors. Both types of microplastics are not only widely distributed in the oceans, but also can adsorb persistent organic pollutants (POPs) and metals. They can be mistaken for food by marine organisms, and the resulting bioaccumulation can have a significant impact on additional ecosystems. In this study, quantitative and qualitative analysis methods for microplastics from the literature were compared and summarized.

In this study, we investigated the distribution of domestic nanomaterials. Zinc oxide (ZnO), titanium dioxide (TiO2), and silver (Ag) nanoparticles, as well as carbon (C) nanotubes, were selected, and their circulation and quantity in use was investigated. We also analyzed leaching and of heavy metals in nanowaste. Chemical composition was determined using Xray diffraction and fluorescence (XRD and XRF) and transmission electron microscopy (TEM). Using XRF and XRD analysis, sludge from a facility using zinc oxide was found to have silicon dioxide (SiO2) and TiO2 as its main components. Sludge from a facility using TiO2 was found to have TiO2 as its main component. Samples of Ag nanoparticle and C nanotubes manufacturer measured elemental components of Ag and C, respectively. TEM analysis showed Si O2 in the form of dust sample from a facility manufacturing ZnO. Carbon nanotube samples of manufacturers were in the form of fibers. Leaching test results showed low concentrations compared to the regulation criteria of the Wastes Control Act. Content result of Zn was detected at -111.7 ~ 24,843.4 mg/kg in ZnO samples. Content result of Ti was detected at 1.51 ~ 35.28 mg/kg in TiO2 samples. Oil mop samples of Ag nanoparticle were detected in Ag (29,643.07 mg/kg) and Cu (15,600.8 mg/kg).

The optimum design and scale-up of a fast pyrolysis reactor require a fundamental understanding of its hydrodynamics characteristics. Extensive investigations have been carried out, both theoretically and experimentally, to understand the hydrodynamic characteristics of gas-solid two-phase flow in a pyrolysis reactor, such as velocity field, solids concentration, and pressure drop. Numerical simulation can provide a promising alternative for studying the hydrodynamics of gas-solid flows in the fast pyrolysis reactor. In this study, computational particle fluid dynamics (CPFD) was used to investigate the hydrodynamic characteristics of bubbling fluidized bed (BFB) and conical spouted bed (CSB) reactors. These characteristics were analyzed in terms of pressure drop, solid distribution, and solid circulation rate. The BFB reactor was found to have a lower efficiency than the CSB reactor. The pressure drop of the CSB reactor was 25% less than that of the BFB reactor. The solid circulation rate of the CSB reactor was 68% greater than that of the BFB reactor.

In this study, leaching and content tests of hazardous substances were analyzed to evaluate their recyclability to paper sludge and paperboard products. These findings were compared with standard controlled waste. In addition, the stability of these products was examined with respect to the recommended standards for heavy metal content in packaging materials. In the leaching test results, no regulated items were detected. Upon examining the stability of paperboard products, it was detected within the standard of most samples. Paper sludge usage accounts for only about 10% of paperboard raw materials. Therefore, harmful substances in paper sludge is not a problem, Leaching and content tests of harmful substances in the antifoaming agent used were investigated within the limits of all items. The pH of the paper sludge corrugated cardboard, and antifoaming agent was 7.49, 7.21, and 7.87, respectively. Therefore, these wastes did not account for the corrosiveness. In addition, there were no hazardous characteristics found for leaching, because all specified waste standards were satisfied.

This study evaluated the heating value derived from waste trees generated by thinning in Daejeon Metropolitan City. These trees are generated and stored in the forest without being handled separately after thinning. They can be used as a source of energy as they have a high heating value and, to avoid landslides during heavy rain, must be taken away from the forests properly. In 2014, statistical data of waste trees in Daejeon showed there were 2,152,352 ㎥ of conifers, 924,836 ㎥ of broad-leaved trees, and 662,914 ㎥ of mixed forest. The moisture content of conifers was 15.8%, that of broad-leaved trees was 11.5%, and that of mixed forest was 13.7%. The ash content of conifers was 7.0%, that of broadleaved trees was 4.0%, and that of mixed forest was 11.4%. All three types of tree satisfy the moisture and ash content criteria for fluff type Bio-SRF, i.e., 25% and 15%, respectively. Therefore, they are deemed sufficiently valuable as a source of energy. The heavy metal (Hg, Cd, Pb, As, Cr) content of conifers, broad-leaved trees and mixed forests each satisfies the heavy metal content criteria for Bio-SRF, i.e., 0.6 mg/kg, 5.0 mg/kg, 100 mg/kg, 5.0 mg/kg, and 70 mg/kg, respectively. The lower heating value of conifers was 5,070 kcal/kg, that of broad-leaved trees was 4,660 kcal/kg, and that of mixed forest was 4,820 kcal/kg. All three types of tree satisfy the lower heating value criteria for Bio-SRF, which is 3,000 kcal/kg, and, therefore, are deemed sufficiently valuable as a source of energy.

In South Korea, as the price of natural minerals and lack of domestic resources increases, the import of waste into certain countries is gradually increasing. The largest portion of waste subject to a domestic import permit are lead-acid batteries. They account for more than 90% of the total import permits. In this study, the current status of waste leadacid batteries imported into Korea and their recycling status at domestic battery recycling sites were investigated. Waste generated from various lead-acid battery recycling plants were investigated for effective management of these batteries in South Korea. In addition, hazardous substances in the waste generated at recycling sites were analyzed to determine their environmental risk. Study sources were selected based on the industries registered on the Allbaro-system. For leaching analysis results, an arsenic content of 30.4 mg/L (1.63 to 109.13) was detected in slag, and 0.018 mg/L (N.D. to 0.018) of mercury was detected in wastewater treatment sludge. The contents of lead in slag and wastewater-treated sludge were measured as 85,599 mg/kg (52,476.4 to 150,466.8) and 41,722 mg/kg (18,082.6 to 68,958.1), respectively. In battery case scrap that was recycled by a second recycling company, lead was found to be 5.79 mg/L, exceeding the designated waste criteria of 3 mg/L. However, after the washing process, lead was no longer detected in the recycled product, P2. We conclude that it is necessary to keep the current secondary recycling process, with recycling after the cleaning process, in order to allow primary recycling companies to appropriately manage designated waste as it is discharged, collected, and transported.

There are tens of millions of animal deaths annually due to infectious diseases such as AI (Avian Influenza) and foot-and-mouth disease. Currently, eco-friendly and economical methods of disposal of the resulting animal carcasses are being studied. Among them, the black soldier fly (Hermetia illucens, BSF) is attracting attention as an alternative to disposal methods that cause environmental pollution, such as incineration or landfills, because of its strong organic decomposition ability. In this study, the efficiency of BSF larvae for decomposition of broiler, pig, or duck was determined. Disposal ability relative to BSF larva level was measured for each. Our results confirmed that all three animals could be decomposed after 48 hours when BSF larva were injected at greater than 300% of the weight of the carcass.

Moisture content is an important factor in landfill gas production and effective landfill stabilization management at bioreactor landfills. Moisture content was experimentally estimated by applying the rainfall hydrograph theory through cover materials, such as the general and bio-solid soil, in the Sudokwon landfill site. The rainfall hydrograph theory was used to analyze the water balance, in which moisture can be strongly affected by infiltration in the water balance. Cover material characteristics, such as bulk density, porosity, specific gravity, and hydraulic conductivity, were used to estimate the water balance of the landfill site. From the results of the water balance, runoff was increased, but evaporation and infiltration were decreased with increasing rainfall rate for both general and bio-solid soil. As the bulk density increased in both general and bio-solid soil, runoff was increased, but infiltration was decreased, because hydraulic conductivity in the cover material was decreased with increasing bulk density. Finally, the moisture content of landfill waste increased linearly, with increasing infiltration through the cover materials, even though the increment in moisture content was decreased along the depth of landfill.
