Novel recycling methods for alkaline batteries

A novel zero-waste and environmentally-friendly process for the recycling of alkaline batteries has been developed.
Novel recycling methods for alkaline batteries
The European Directive on batteries has imposed the recycling of all primary and secondary batteries. Eighty percent of rechargeable batteries are alkaline. Thus, a hydrometallurgical route for the recycling of alkaline and zinc-carbon batteries by recovering zinc and manganese from used alkaline cells has been developed by an Italian university research group.

The new process consists of a pre-treatment step in which paper and steel are sorted from the electrode substances and recovered. Following this, a leaching step retrieves manganese and zinc as sulphates in separate solutions. In this way, nearly one-hundred percent of the materials from the used cells can be recovered and converted into a marketable form.

Another advantage of this new process is its low energy consumption, zero emission and zero waste. Unlike other processes for battery recycling, this process allows recovery of zinc and manganese as well as all the other materials. Furthermore it is the only battery recycling method that allows the reassembly of new batteries from the recovered materials. Manufacturing agreement and technical cooperation are sought.
