DISPOSAL

Dispose of the packaging material in an environmentally friendly manner so that it can be recycled.

Batteries must not be disposed of together with the domestic waste. Consumers are legally obliged to separate and recycle batteries. Batteries can be taken free of charge to a collection point of your local authority/district or in shops so that they can be disposed of in an environmentally friendly way and valuable raw materials can be recovered. If they are not disposed of properly, toxic ingredients may enter the environment and have harmful effects on people, animals and plants. Only dispose of batteries when they are discharged. If possible, use rechargeable batteries rather than single-use batteries. The adjacent symbol (crossed-out bin underlined) means that used devices should not be disposed of in the domestic waste, but should instead be taken to special collection and return systems. Owners of used devices must remove used batteries from the used device and dispose of them separately (see also the section on battery disposal). Owners of used devices from private households can take them free of charge to the collection points of the public waste disposal authorities or the disposal points which are set up by manufacturers and distributors under the Electrical Equipment Act. Businesses which market electrical and electronic devices are also obliged to take back used devices.
