…End-of-life disposal
ABB is committed to ensuring that the risk of any
environmental damage or pollution caused by any
of its products is minimized as far as possible. The
European Waste Electrical and Electronic
Equipment (WEEE) Directive that initially came into
force on 13 August 2005 aims to reduce the waste
arising from electrical and electronic equipment;
and improve the environmental performance of all
those involved in the life cycle of electrical and
electronic equipment.
