Sustainable System Design for Collection and Recycling of E-waste in the United StatesWhere Are They Now? Currently, Dr. Kim is a post-doctoral associate conducting a study about renewable energy systems (e.g., Biofuel and energy) in Department of Bioproducts and Biosystems engineering at University of Minnesota.

Project Description (while EREF Scholar):
Electronic waste, commonly known as e-waste, waste electrical and electronic equipment (WEEE), or end-of-life (EOL) electronics, denotes electronic and electrical equipment, including all components, sub-assemblies, and consumables, deemed obsolete or unwanted by a user (Bhuie et al., 2004; Cairns, 2005). Functionality of information and communication technology (ICT) is growing rapidly, and from a sustainability viewpoint, there are clearly social benefits to ICT’s technological revolution that contribute to its continuity. As technology advances, people purchase increasingly more electronic devices (such as computers, entertainment electronics, mobile phones and others) even though they are not essential. Meanwhile, the significant increase in e-waste has not corresponded to growth in the processes related to collection, recycle and reuse of these electronic devices. For example, it is estimated that 9% of the electronics sold between 1980 and 2004 in the United States (U.S.), or 180million units, are still in storage awaiting disposal; TVs and desktop PCs account for 34-52% and 24% (by weight), respectively (U.S. EPA, 2007a). Also, in 2005, the U.S. discarded 1.36-1.72million metric tons of e-waste, mainly into landfills, and only 0.31-0.34million metric tons were recycled (U.S. EPA, 2007a). Consequently, the typical life cycle of an electronic product is a linear progression between manufacturing, use, storage and waste disposal.

Given this context, a form of deposit refund system was designed to ensure proper end-of-life while at the same time establishing a competitive market for reuse and recycling services. The proposed system is termed the e-Market for Returned Deposit. The core concept of the system is that consumers pay a deposit at time of purchase, a variable portion of which is returned when turned in at the end-of-life. This deposit should be sufficient enough to cover transportation and recycling cost of the product. Reuse and recycling firms compete on an electronic market to receive the deposit by bidding different values of rebates to consumers.

Biography:
Dr. Kim is conducting a study about renewable energy system (e.g., Biofuel and energy) in Department of Bioproducts and Biosystems engineering at University of Minnesota. He holds a Ph.D. from Civil, Environmental and Sustainable Engineering at Arizona State University in 2009, a Master’s degree in Civil and Environmental Engineering from Carnegie Mellon University and Environmental Engineering from Inha University in South Korea, and a B.S. in Environmental Engineering from Cheongju University in South Korea.

In the University of Minnesota, current Dr. Kim is doing a project funded by DOE/USDA, which is “Sustainable Pathways to Achieving Biofuel Policy Goals”. As project coordinator, he is developing life cycle assessment module for this project. With the proposed work, our overall objective is to provide strategic guidance for improving environmental quality and cost effectiveness in achieving the biofuel production goal. To do this he is identifying and quantifying the tradeoffs associated with possible pathways to achieving national biofuel production goals under given physical, economic and institutional constraints, such as spatially distributed climate conditions, feedstock availability, land and water availability, transportation and logistics infrastructure, production cost and relevant regulations.
