Recycling Batteries - Battery Council International

Monday, June 4, 2018
Do you know how the plastic cases of batteries are recycled? The polypropylene pieces are washed, blown dry and sent to a plastic recycler where the pieces are melted together into an almost-liquid state. The molten plastic is put through an extruder that produces small plastic pellets of a uniform size. Those pellets are sold to the manufacturer of battery cases, and the process begins again.
