Imagine a resource so durable that most of what humanity has mined over centuries remains in use today. Copper’s recyclability is nothing short of remarkable, around 80% of all the copper ever mined in human history is still in circulation. Thanks to this enduring material loop, copper stands as one of the most sustainable metals in active use.

This high retention rate is driven by copper’s unique property; it can be recycled infinitely without any loss of performance or purity. From wires, plumbing, and roofing sheets to old electronics, each represents part of that vast stock that continues to serve new purposes. According to the International Copper Association, over 65% (two-thirds) of the ~690 million tonnes of copper produced in the last century remain in productive use today.

Beyond conserving resources, recycling copper delivers major environmental benefits. It requires far less energy than primary mining and smelting, significantly reducing greenhouse gas emissions and easing pressure on newly mined ore.

In short, copper’s longevity both in use and through recycling loops embodies the circular economy in action.
