Disposal (E-waste recycling instructions)
All electronic waste is made up of chemicals such as lead, cadmium, beryllium, mercury, and brominated flame retardants. Improper disposal increases the chances of these dangerous chemicals contaminating the soil, polluting the air, and leaching into water bodies. Please find an e-waste recycler who is officially certified by the Basel Action Network (BAN).
Electrical and electronic equipment that has become waste is referred to as old equipment. Owners of WEEE must dispose of it separately from unsorted municipal waste. Old appliances do not belong in household waste, but in special collection and return systems. Owners of old appliances must separate old batteries and accumulators that are not enclosed in the old appliance, as well as lamps that can be removed from the old appliance without destroying it. This does not apply if the WEEE is handed over to public waste management authorities and separated from other WEEE there for the purpose of preparation for reuse.
The symbol of a crossed-out wheeled garbage can regularly displayed on electrical and electronic equipment indicates that the respective device must be collected separately from unsorted municipal waste at the end of its service life.
