    Abstract : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. READ MORE

    Abstract : Rare earth elements (REE) are a group of elements that are of critical importance in numerous technological applications, including “green technologies” such as wind turbines and hybrid car batteries. When the criticality of applications is considered, problems in supply has brought the option of effective secondary resource utilization into consideration. READ MORE
