10. DISPOSAL OF OLD ELECTRICAL APPLIANCES
The European directive 2012/19/EU on Waste Electrical and Electronic
Equipment (WEEE), specifies that old household electrical appliances must
not be disposed of with the normal unsorted municipal waste. Old
appliances must be collected separately, in order to optimize the recovery
and recycling of the materials they contain and reduce the impact on
human health and the environment.
The crossed out "wheeled bin" symbol on the product reminds you of your obligation to
dispose of the appliance correctly.
Consumers must contact their local authorities or retailer for information concerning the
correct disposal of old appliances and/or their batteries.
