Technical Specifications

Computer Recycling

DIGITAL's Global Supply Operations Americas Materials Recovery Operation is one
of the first 20 organizations in the world to register with the ISO 14001 certification.
This facility handles the return and disposition/disassembly of DIGITAL products.
The new ISO 14001 standards measure efforts in pollution prevention, preserving
natural resources, and protecting the environment. While this facility handles about
25 million pounds of discarded electronic equipment per year - everything from
copying machines and pagers to computer equipment from all manufacturers - less
than one-tenth of one percent of the material ends up in landfills. The product
materials are reused and recycled. Many products can be refurbished and sold intact
to used-equipment brokers.
