  • Demand for copper could increase by 213341% by 2050, and

    Demand for copper is rising faster than it can be recovered from secondary sources e.g. industrial and consumer waste, such as pipes, brass and old electrical appliances and, as a result, reliance on primary copper which must be mined is increasing. Estimates suggest that copper reserves could be depleted in just 25 to 60 years1.
