Marjorie Valix

Professor Marjorie Valix is an Associate Professor in the School of Chemical and Biomolecular Engineering at the University of Sydney, where she has been a faculty member since 1998. She holds a PhD and undergraduate degrees from UNSW. Her research focuses on sustainable resource recovery and waste valorization, particularly through bioleaching and hydrometallurgical processes.

Research Focus Areas:

• Biohydrometallurgical extraction of metals from e-waste and industrial byproducts
• Development of sustainable construction materials from industrial wastes
• Advanced separation technologies for environmental remediation
• Low-carbon recycling processes for energy storage materials

Her recent publications demonstrate strong emphasis on circular economy approaches, including recycling of lithium-ion batteries, copper recovery from e-waste, and CO2 sequestration using industrial wastes. Research trends show consistent focus on integrating chemical and biological processes for sustainable resource recovery.

Current Projects:

• Novel hybrid geopolymers for concrete infrastructure protection (SmartCrete CRC)
• Decision support tools for sewer infrastructure management (SmartCrete CRC)
• Smart Linings for Pipe and Infrastructure (Water Services Association)
