Copper - a Natural ResourceFact 5 of 6
Man has been recycling copper throughout history. During the Middle Ages, which saw frequent conflicts, bronze (an alloy of copper and tin) cannons were typically melted down after each war and made into more useful items. Discarded electrical wiring, plumbing tube, cartridge cases from the military, automobile radiators and production scrap are some of the main sources for reclaimed copper today.
