  • Manufacturers have been reusing and recycling copper for many years.
  • 2
  • Now they are increasing their efforts because some experts predict that the need for the metal will nearly double by 2035.
  • 3
  • The demand for copper might partly come from a move away from fossil fuels.
  • 4
  • There is a movement to power buildings, vehicles and manufacturing operations with clean electricity.
  • 5
  • Some people hope to "electrify everything."
  • 6
  • But doing so would require more copper.
  • 7
  • The other half of the reported increased demand comes from constructing buildings and making cell phones and data centers.
  • 8
  • In an industrial area near Montreal, there is a factory owned by the French company Nexans that recycles copper.
  • 9
  • Nexans is one of the world's largest wire and cable manufacturers.
  • 10
  • In the factory, sheets of copper move along a special product mover four stories above the floor of the factory.
  • 11
  • The sheets then drop into a hot furnace.
  • 12
  • Next come pieces of copper wire.
  • 13
  • Out of the furnace comes liquid copper.
  • 14
  • It travels to a second furnace and from there, melted copper flows out.
  • 15
  • The liquid is then shaped into long, thin pieces called rods.
  • 16
  • These are the raw materials for copper wire.
  • 17
  • The Nexans mill has made copper rod from rock, called ore, for nearly one hundred years.
  • 18
  • Now it processes an increasing amount of used copper.
  • 19
  • Fourteen percent of some of the rods are recycled metal.
  • 20
  • The company hopes to increase that to 20 percent.
  • 21
  • "We say to our customers: Your waste of today, your scrap of today is your energy of tomorrow, so bring back your scrap," said Nexans chief Christopher Guérin.
  • 22
  • Every ton of copper that is recycled means that up to 200 tons of ore will not need to be mined.
  • 23
  • That is important because mining can harm the environment, causing pollution in the soil, water or air.
  • 24
  • Copper is an especially good candidate for reuse, because it can be recycled endlessly without losing its value or performance, Guérin said.
  • 25
  • Each day, up to 10 trucks drop off wire, cable and copper scrap at the Nexans mill.
  • 26
  • Nexans uses more than 2,600 times the weight of New York City's Statue of Liberty in copper each year.
  • 27
  • Some of the materials come from customers, some from scrap dealers.
  • 28
  • The purity must be high if it is to be used to carry electricity.
  • 29
  • Daniel Yergin is with the financial information company S&P Global.
  • 30
  • He said people may have a closer connection to this metal and this mill than they realize.
  • 31
  • Copper connects people to the world, Yergin said.
  • 32
  • "We depend on electricity for everything now," he said.
  • 33
  • "None of it works without copper."
  • 34
  • Aluminum is also used for electrical wiring in some cases.
  • 35
  • But it takes a lot of energy to produce.
  • 36
  • Some aluminum factories, where machines separate metal from ore, have cut production or closed because electricity prices are so high.
  • 37
  • These cuts and closures have added to the demand for copper.
  • 38
  • The International Copper Association (ICA) says about two-thirds of all the copper produced in the last 100 years is still in use.
  • 39
  • It is used in electrical systems, communications and home appliances.
  • 40
  • When equipment and machines get past their useful life, they represent a large supply that can be recycled in the future, the trade group said.
  • 41
  • Colin Williams of the USGS Mineral Resources Program said companies should recycle more of the copper that is already out there.
  • 42
  • By recycling, companies can make use of what is, effectively, an "urban mine."
  • 43
  • "It increases the supply available," Williams said.
  • 44
  • He added that recycling "...reduces the energy and environmental impacts associated with new mining by being able to reuse material we've already mined. It's an important step."
