HYDROCHEMICAL ROUTES TO RECYCLE NIMH BATTERIES AND FLUORESCENT LAMPS Professor Christian Ekberg www.inl.gov Nuclear Chemistry and Industrial Materials Recycling, Department of Chemistry and Chemical Engineering, Chalmers University of Technology, 412 96 Gothenburg, Sweden It is clear that with the exception of energy, the availability of raw materials, especially minerals, will be one of the big questions for the continuous development of the world from this point on. Many of the minerals and elements we are heavily dependent on today are running scarce and their mining is sometimes questionable from both environmental and ethical points of view. Seen in this context recycling has become more and more interesting. Many of the materials we use today can be rather efficiently recycled if they are collected and sorted in the right way. In this paper we will focus on two fairly concentrated secondary mineral sources: the used NiMH batteries from hybrid electric vehicles and the fluorescent lamp wastes. We focus our investigations on collected material since in Sweden the sorting facilities and the societal commitment to waste handling is rather efficient. This provides a fairly uniform stream of waste material to be handled in the recycling facility. This paper gives an account on both the dismantling as well as the recovery of the metals and their separation into pure streams ready for reuse into the society replacing virgin material. For these two cases processes have been developed to pilot plant scale. When: Where: Time: Who: January 5, 2016 CAES Auditorium 10:30 AM Interested Employees
