초록

In recent years more than millions of discarded electronic devices, also called electronic waste (in short e-waste), are being retired each year in Korea because of rapid technology development of the electronic industry and common replacement of the devices by consumers with newer ones. In order to more effectively recover and process the e-waste produced from the consumers and to reduce its impact on the environment, the Korean Ministry of Environment (Korean MOE) has promulgated an extended producer responsibility (EPR) regulation for a number of electronic equipment in 2003. In 2007, a new legislation, ‘the Act on the Resource Recycling of Waste Electrical Electronic Equipment (WEEE) and End-of-life Vehicles’ was enacted to improve the overall environmental performance of electronic products during their life cycle. This paper discusses the estimation of generation rate and disposal practices of end-of-life electronic devices by the consumers in Daejeon Metropolitan City. The study are based on a survey of 359 consumers(local residents), a review of the available literature, and conversations with local authorities. The results show that approx. 1.05million units of electronic wastes were retired with the highest number of mobile phones (more than 620,000 units) in the City as of 2009. In 2015, about 1.3 million units of the devices are expected to be retired. The results of the survey indicate that the average replacement periods ranged from 2.3 year for mobile phone to 7.8 year for refrigerator and washing machine. The principal interest regarding e-waste is the recovery of the precious metals such as iron, copper, aluminum, and cobalt. Gold, silver, and palladium are also of economic interest. Upon recycling, economic values of ewaste retired and generated by the city in 2009 are estimated to be 30.2 billion won and 14.1 billion won, respectively. Local governments, consumers, retailers, and producers related to e-waste recycling should consider more collective actions that can be taken to promote successful collection and recycling schemes with a perspective of economic reason and resource recovery.
