Nowadays almost any kind of battery can be recycled, regardless of whether it contains a silver oxide, nickel metal hydride, nickel cadmium, alkaline manganese or zinc oxide electrochemical system. Alkaline batteries are recycled in metal industry, where steel, zinc and ferromanganese can be recovered. From the NiCd/NiMH batteries cadmium and nickel is recovered, from Li-Ion batteries, cobalt is recovered, and from button batteries, mercury can be recovered.
Legislation prescribes that when WPBA is processed, the objectives from the Directive must be fulfilled, which obligate all manufacturers to do the following:
- 65% recycling rate with regard to the average mass of lead batteries and acid accumulators, including the recycling of lead in batteries and accumulators;
- 75% recycling rate with regard to the average mass of nickel-cadmium batteries and accumulators, including the recycling of cadmium in batteries and accumulators;
- 50% recycling rate with regard to the average mass of other waste batteries and accumulators.
