| Abstract Scope |
As emerging technologies drive up demand for rare earths, value recovery from recycling end-of-life products provides an option for partially closing the material loop, conserving natural capital and enhancing resource security. Yet the techno-economic feasibility of recycling depends on uncertainties associated with the feed input to the recovery process and the effect of these uncertainties on the viability of the recycling facility. In this study, we couple a first principles solvent extraction model with an economic model for a separations facility and apply it to assess byproducts recovery and rare earths separation from spent nickel-metal hydride batteries, illustrating the significance of parametric uncertainties. The study shows the importance of risk-informed decision making in the investment, design, and operation of recycling facilities. |
