This National Science Foundation (NSF) project grant under CFDA 47.041 - Engineering aims to develop an innovative and integrated bio- and physico-chemical process to effectively recover critical metals from municipal solid waste (MSW) landfill leachates. The $915,128 award to Purdue University, with a project period from August 1, 2024 to July 31, 2028, will fund research to: 1) characterize critical metal content in existing US landfill leachates, 2) examine the use of in-situ biofilms for bioleaching, 3) elucidate the complex chemistry of metals in landfill leachate, 4) advance membrane technology for selective ion separations, and 5) conduct life cycle and techno-economic assessments. The project aims to establish baseline critical metal data, promote bioleaching performance, clarify metal speciation chemistry, fabricate selective ion-separation membranes, and evaluate the economic and environmental impacts of the overall recovery process. This research will help inform technical innovations and drive a paradigm shift in how MSW and associated leachates are managed to enable a more circular economy and sustainable future.
