Method & Evidence

AimTo evaluate the techno-economic feasibility and environmental impact of producing biolixiviants from various waste materials for metal recovery.
MethodTechno-economic analysis and Life Cycle Assessment (LCA)
ProcedureGluconic acid production was modeled using corn stover, date palm clippings, and nonrecyclable paper. Techno-economic analysis determined production costs, and LCA assessed environmental impacts. The performance of the derived biolixiviants was tested in the bioleaching of neodymium–iron–boron magnet swarf.
