Crocodile is the first of a kind commercial compact system for the efficient recovery of cobalt designed with novel integrated leading technologies. The Crocodile project aims to drastically reduce the supply risk of cobalt for the European industries by increasing the efficiency of recovery processes for cobalt (and other relevant materials). We strive to do so with lower energy costs and environmental impacts, providing solutions with low capital investment costs. And finally, we want to maximize the exploitation of our ‘local’ waste. How IDENER contribute to Crocodile? We are in charge of the development of the engineering design and the construction, commissioning and start-up of the mobile plant.
