E-Scrap Recycling 3 categories Reuse

E-Scrap Recycling • 3 categories – Reuse • Reusing the entire item – Recovery • Reusing components from the item. – Reclamation • Reclaiming the materials making up the item. ISO 9001: 2000 ISO 14001: 2004 IAER Certified Electronics Recycler

Gold Recycling Facts • An estimated 137, 000 tons of Au have been mined from historic times to 1998. (Mining dates back to 4000 BC) • Approximately 85% of all of the gold ever mined is either in use or museums. • Approximately 1/3 of the annual usage of gold is from recycled sources. • The bulk of recycled Au is refined in Europe and Canada. ISO 9001: 2000 ISO 14001: 2004 IAER Certified Electronics Recycler

Copper Recycling Facts • An estimated 350 billion tons of Cu have been mined from historic times to 1998. (Mining dates back to 4000 BC) • Approximately 90% of all of the copper ever mined is still in circulation. • Approximately 37% of the annual usage of Cu is from recycled sources. • Recycled Cu is refined world-wide.

E-Scrap Recycling Why Recycle? • Saves energy • Scrap “secondary materials” important feed material – Energy savings – especially in the metals industry • Saves the environment • Sustainability – – Scrap metal replaces mined materials – Scrap paper replaces trees – Scrap plastic decreases our dependence on foreign oil » Plastic made from petroleum • It’s the right thing to do.
