The German batteries act stipulates that automotive, industrial and portable batteries must not disposed in private household waste. There are several good reasons not to do so.
On one hand batteries contain valuable raw materials such as metals that could be recycled and reused. Moreover, batteries contain harmful substances like Mercury, Lead or Cadmium which are harmful for people, animals and the environment.
The German batteries act therefore requires producers of portable batteries to join a battery take-back scheme that will take care of the environmental sound collection and recycling of waste portable batteries. The cost for the collection and the recycling have to be borne by the producers.
Furthermore, the German batteries act requires municipal collection sites, recycling organizations and distributors of portable batteries to collect waste portable batteries free of charge from consumers and hand them over to a take back scheme.
Producers of automotive industry batteries have to for fill their vacations from the batteries act through offering distributors and treatment facilities to take automotive and industrial batteries back free of charge and to treat and recycle those batteries at their own cost.
