the environment and human health. It is a precondition for reuse
and recycling of used electrical and electronic equipment. For
more detailed information about disposal of your old appliance,
please contact your local authorities or waste disposal service.
In support of the global requirements to dispose of electrical waste within environmentally
acceptable specifications, Norwegian Subsea offers customers the take-back and recycle
process to properly dispose of surplus and end-of-life products.
Equipment that is returned to Norwegian Subsea through this program is disposed of in
an environmentally safe manner using processes that comply with the WEEE (EU Directive
on Waste Electrical and Electronic Equipment) regulations. All Norwegian Subsea-branded
products are accepted under the program.
