End-of-life batteries management and material flow analysis in South Korea

引用

Frontiers of environmental Science & Engineering 2018年第3期12卷 55-67页

作者： Hyunhee Kim Yong-Chul Jang Yeonjung Hwang Youngjae Ko Hyunmyeong Yun Department of environmental Engineering Chungnam National University Daejeon 34134 South Korea Waste to Energy Research Division Environmental Resources Research Department National Institute of Environmental Research Incheon 22689 South Korea daejeon green environment center Daejeon 34134 South Korea

Consumers increasingly have worn-out batteries as electrical and electronic equipment with new technical developments are introduced into the market and quickly replace older models. As a result, large amounts of end-of-life （EOL） or waste batteries are generated. Such batteries may contain a variety of materials that includes valuable resources as well as toxic elements. Thus, the proper recycling and management of batteries is very important from the perspective of resource conservation and environmental effect. The collection and recycling of EOL batteries is relatively low in South Korea compared to other countries, although an extended producer responsibility （EPR） policy was adopted for battery recycling in 2003. In this study, the management and material flow of EOL batteries is presented to determine potential problems and quantitative flow, based on literature review, site visits to battery recycling facilities, and interviews with experts in the Korea Battery Recycling Association （KBRA）, manufacturers, and regulators in government. The results show that approximately 558 tons of manganese-alkaline batteries, the largest fraction among recycling target items, was disposed in landfills or incinerators in 2015, while approximately 2,000 tons of batteries were recovered at a recycling facility by simple sorting and crushing processes. By raising environmental awareness, more diverse and effective collection systems could be established for consumers to easily dispose of EOL batteries in many places. Producers, retailers and distributors in South Korea should also play an important role in the collection of EOL batteries from consumers. Lithium-ion batteries from many electronic devices must be included in the EPR system for resource recovery.

AIM: To evaluate the effects of Cordyceps militaris extract (CME) on angiogenesis and tumor growth. METHODS:Human umbilical vein endothelial cells (HUVEC), HT1080, and B16-F10 cells were used. DNA fragment, angio-genic related gene expressions (MMPs, bFGF, VEGF, etc), capillary tube formation, wound healing in vitro, tumorgrowth in vivo were measured. RESULTS: CME inhibited growth of HUVECs and HT1080 (P<0.01). CME 100and 200 mg/L reduced MMP-2 gene expression in HT1080 cells by 6.0 % and 22.9 % after 3-h and 14.9 % and32.8 % after 6-h treatment. CME did not affect MMP-9 gene expression in B16-F10 melanoma cells. CME 100 and200 mg/L also reduced bFGF gene expression in HUVECs by 22.2 % and 41.3 %. CME inhibited tube formation ofendothelial cells in vitro and in vivo. CME repressed the growth of B16-F10 melanoma cells in mice compared withcontrol group (P<0.05). CONCLUSION: CME has antiangiogenetic properties.
