End-of-life product recycling

Grass Valley’s innovation and excellence in product design also extends to

the programs we’ve established to manage the recycling of our products.

Grass Valley has developed a comprehensive end-of-life product take back

program for recycle or disposal of end-of-life products. Our program meets

the requirements of the European Union’s WEEE Directive and in the United

States from the Environmental Protection Agency, individual state or local

agencies.

Grass Valley’s end-of-life product take back program assures proper disposal

by use of Best Available Technology. This program accepts any Grass Valley

branded equipment. Upon request, a Certiﬁcate of Recycling or a Certiﬁcate

of Destruction, depending on the ultimate disposition of the product, can be

sent to the requester.

Grass Valley will be responsible for all costs associated with recycling and

disposal, including freight, however you are responsible for the removal of

the equipment from your facility and packing the equipment ready for pickup.

Information concerning the program can be found at:
