Waste electrical and electronic equipment (WEEE), also called electronic waste (in short e-waste), is one of the fast growing waste streams in Korea and around the world. This results partly from rapid technology development of electronic industry and common replacements of the devices by consumers with newer ones. In order to more effectively recover and process the WEEE produced from consumers and to reduce its impact on the environment, Korea Ministry of Environment (Korea MOE) promulgated an extended producer responsibility (EPR) regulation for a number of electronic equipment in 2003. In 2007, the Act of Waste Electrical and Electronic Equipment (WEEE) was enacted to avoid the disposal of end-of-life consumer devices and setting high recycling targets for the percentages of the products that have to be collected. The WEEE Act specifies 10 different types of electrical and electronic equipment, and each item has a defined recycling and recovery target rate annually. This paper discusses the estimation of proper recycling target rate of WEEE in Korea by using the Monte-Carlo simulation. The simulation was made, based on a number of considerations and input assumptions, including the increased recycling rates by producers, retailers, municipalities and improved recycling policy to be introduced by the government. This study was performed based on the review of recent recycling statistics, available WEEE-related literature, and the conversations with environmental authorities and Korea Association of Electronics and Environment. The Monte-Carlo simulation results with iterations of 100,000 showed that in 2017 on average approx. 5.15 kg/per capita of WEEE with 5% percentile 4.58 kg/per capita and 95% percentile 5.79 kg/ per capita are expected to be recycled, while on average 3.69 kg/per capita of WEEE with 5% percentile 3.51 kg/per capita and 95% percentile 3.88 kg/ per capita are predicted to be recycled in 2013. Large household appliances with on average approx. 3.72 kg/per capita in 2017 are estimated to be the largest category among the WEEE category, followed by audio and video equipment (0.80 kg/per capita/yr) and IT telecommunication (0.45 kg/per capita/yr). In 2014, the national recycling rate of WEEE is expected to be about 4.0 kg/capita, which is the same as the EU average collection and recycling target rate by EU WEEE Directive. Not only electronic industry producers and retailers but local governments and consumers related to WEEE collection and recycling should take more collective actions to promote successful collection and recycling schemes as well as to nationally achieve recycling target rates predicted by this study.
