…1 Health & Safety

…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.
