Abstract: Electronic waste is the fastest-growing type of waste, with an estimated 3–4% growth, reaching over 50 Mt of e-waste every year. In addition, electronic devices have been shown to contain gold and copper grades that exceed the grades of many operating mines. The recycling of metals from e-waste is studied under the urban mining discipline and provides opportunities for the recovery of many valuable metals and critical materials. The development of methods for e-waste recycling and for the recovery of metals from electronic waste is wide-ranging, interesting, and technically challenging, yet not a lot of fundamental research is dedicated to studying the best approaches for the recovery of value from this waste stream.
The Urban Mining Innovation Centre of Mining Engineering at UBC is engaged in the research related to the recovery of value from municipal and industrial waste, and includes major projects in e-waste recycling. The major projects are related to LED recycling, the recovery of the non-metal fraction from printed circuit boards and cellphones, and the recovery of Au from electronics using environmentally friendly techniques, using of eco-friendly reagents. This seminar will showcase recent research in the area of urban mining at UBC-UMIC, focusing on e-waste recycling that is dedicated to the development of safer, economically viable, and more environmentally friendly recycling techniques that minimize losses of material and lessen the environmental impact. This will also include an exploration of novel, non-conventional, and alternative techniques for the extraction of valuable metals and less valuable components such as non-metal and plastic fractions e-waste for further utilization.

Bio: Assistant Professor, Mining Engineering, University of British Columbia; co-founder and leading scientist of the Urban Mining Innovation Center, UBC. More than 30 years of experience in Mineral Processing Engineering working with the industry, academia, and government. Previously worked at the University of Alberta, then Alberta Research Council, Edmonton, Alberta, also held a senior Licensed Scientist position at the British Columbia Ministry of Energy in Victoria, B.C, and through the years she was continuously engaged in consulting for the mining industry. She worked at the Julius Kruttschnitt Mineral Research Centre, at the University of Queensland, Australia and she was a Senior Research Engineer at Teck Resources, the largest Canadian mining company before joining UBC as a faculty. In 2015, she co-founded the Urban Mining Innovation Center dedicated to research in the area of waste re-processing. The Center has attracted several local recycling companies to collaborate with on the recovery of valuable metals and non-metal fractions from the otherwise municipal waste streams such as e-waste, LED, and plastic. For this activity, she has been interviewed by BBC, CBC, Radio Canada International, and India Today.
