Copper recycling and sustainability - Benefits of recycling

Recycling copper uses much less energy, about 10GJ/tonne, that's only 10% of the energy needed for extraction. This energy saving leads to the conservation of valuable reserves of oil, gas or coal and reduces the amount of CO 2 released into the atmosphere. Conservation of copper ore To date only about 12% of known copper resources have been mined.
