The objective of recycling is optimum recovery of the metals and other recyclable materials contained in the waste stream, in order to reintroduce them to the material cycle and thus to ensure economic recycling in qualitative and quantitative terms
All other types of batteries (e.g. nickel-cadmium batteries) are recycled by carefully selected contracting companies.
Recycling of Primary Batteries at Our Locations in Dietzenbach and Bremerhaven
The pre-sorted zinc-carbon and alkaline-manganese batteries are mechanically processed and separated into an iron fraction and a metal-carbon mixture, known as black mass. The high-quality iron scrap is sold for stainless steel production, re-entering the material cycle. The black mass, which contains zinc, is further processed by means of a rolling process, in which zinc oxide is obtained as well as slag, which is used in road construction.
Processing of the batteries and the packaging of recyclables is performed in a closed system that is extremely environmentally friendly in terms of dust, noise and exhaust. Waste water is not produced in any step of this process. Any mercury or other pollutants contained in the exhaust gas are collected completely by activated carbon filters.
