In order to extract copper from copper ore the energy required is approximately 100GJ/tonne. 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 CO2.
