Abstract

In this study, metal and nonmetal contents and their economic values in ICT devices such as smart phones and laptop computers were evaluated. The electronic devices made by LG and Samsung were disassembled into 5 parts, which are printed circuit board assembly, battery, display, case and other electronic components. Metal and nonmetal contents in these parts were analyzed, and their economic values were calculated via multiplying the materials' contents by metal price obtained from KOMIS or nonmetal exchange price acquired from Korean recycling markets. Finally, the materials' contents and values according to each electronic parts and electronic devices were calculated. The results showed that the value of the smartphones and laptop computers of LG are 4,449.6 KRW (28,506 KRW/kg) and 6,830.2 KRW (7,053 KRW/kg), and those of Samsung are 1,849.3 KRW (13,499 KRW/kg) and 6,667.5 KRW (4,831 KRW/kg), respectively. It was also found that most of the value was concentrated in batteries and printed circuit board assemblies. In addition, Co, Au and Cu were found to be the most valuable resources in the devices.

본 연구에서는 대표적인 ICT 기기인 스마트폰과 노트북 PC 내 존재하는 금속 및 비금속의 함유량과 가치를 평가하였다. LG와 삼성에서 제조한 스마트폰과 노트북 PC를 인쇄회로기판, 배터리, 디스플레이, 케이스, 그 외 기타 부품 등 5개 파트로 분리하였다. 각 파트에 존재하는 금속 및 비금속의 함유량을 분석한 후 이에 2017년 평균 금속 거래 가격, 국내 재활용 시장에서의 플라스틱 및 유리의 거래 가격을 곱하여 각 파트의 자원화 가치를 산출하였다. 이로부터 각 파트 내 금속 및 비금속의 질량 비율과 가치 비율을 구하고 최종적으로 각 기기 내 금속 및 비금속의 질량 및 가치 비율을 산정하였다. 그 결과, LG의 스마트폰과 노트북 PC가 각각 4,449.6원(28,506원/kg), 6,830.2원(7,053원/kg), 삼성의 스마트폰과 노트북 PC가 1,849.3원(13,499원/kg), 6,667.5원(4,831원/kg)의 자원화 가치를 가지는 것으로 나타났다. 대부분의 가치는 배터리와 인쇄회로기판에 집중되어 있는 것으로 분석되었고 Co, Au, Cu 등이 주요 가치있는 자원인 것으로 확인되었다.
