The World Resources Institute (WRI), a global nonprofit focused on sustainable development, has released a comprehensive report underscoring the critical role of copper in the clean energy transition. Describing copper as “one of the most crucial minerals needed” to advance renewable energy, the WRI calls for enhanced efforts to improve copper recycling and circularity to meet growing global demand.
With nearly 2,000 staff members across the world, WRI’s mission is to drive transformative research aimed at reshaping food, energy, and urban systems for a sustainable future. In its latest report, the institute warns that as the shift towards renewable energy accelerates, copper demand could soon exceed current production capacities. The solution, according to WRI, lies in expanding recycling efforts.
Copper’s Growing Role in Renewable Energy
As the world transitions to clean energy, copper is becoming indispensable. According to WRI researchers Xixi Chen and Ke Wang, power systems based on renewable energy sources could require up to 12 times more copper than traditional fossil-fuel-based systems. The mineral is also vital for the electric vehicle (EV) industry, which uses two to three times more copper than conventional gasoline-powered cars.
Copper, when sourced from recycled materials, offers a significant environmental advantage. The WRI report cites the International Copper Association, revealing that recycling copper can save up to 85% of the energy required compared to traditional mining and extraction processes.
Challenges and Opportunities in Copper Recycling
Currently, copper recycling is largely driven by the private sector in North America and Europe, where its value is well understood. However, the WRI emphasizes the need for more robust government policies to boost recycling rates. Notably, initiatives such as the European Union’s End-of-Life Vehicles Directive and the establishment of the China Resource Recycling Group in China serve as examples of governmental efforts to support copper recycling.
One of the most promising areas for increasing copper recovery lies in electronic waste (e-waste), which the WRI report highlights as the world’s fastest-growing waste stream, reaching 62 million tons annually. As electronic products reach the end of their life cycle, the opportunity to reclaim copper becomes increasingly important.
Global Disparities in Copper Recycling
The report also draws attention to significant disparities in the global copper recycling ecosystem. While regions like the U.S. and Europe are leading in generating and collecting copper scrap, China and other Asian countries dominate the smelting and refining stages. The WRI suggests that shortening the recycling loop could improve the end-of-life copper recycling rate in a way that is both environmentally and socially responsible.
The WRI calls for greater collaboration between governments and the private sector to create policies and incentives that will accelerate the expansion of refining capacity, particularly for lower-grade copper scrap.
Increasing Copper Collection and Recycling
In a move that could challenge established practices in the copper recycling sector, the WRI advocates for government-led efforts to enhance collection systems. While copper theft for recycling is a well-known issue in some regions, the report argues that concerted efforts by consumer groups, retailers, municipalities, and NGOs to raise public awareness could significantly increase the collection of end-of-life products. The WRI also suggests that public authorities and standardization organizations could work to develop transportation solutions for collected scrap to improve efficiency in recycling.
Collaboration with Manufacturers to Boost Recycled Copper Use
Finally, the WRI calls on copper fabricators and manufacturers to embrace recycled copper in their products. The institute stresses the importance of collaboration between recyclers, semi-fabricators, and end-use industries to increase awareness of the benefits of using recycled copper. Furthermore, aligning on purity standards could unlock the market potential for recycled copper sourced from end-of-life scrap.
As the demand for copper continues to rise in the wake of the global clean energy transition, the WRI’s report highlights the urgent need to improve recycling systems and increase the use of recycled materials. Through a combination of government action, industry collaboration, and public awareness, the institute argues that copper recycling can play a pivotal role in achieving a sustainable energy future.
