Recycled Copper: An Untapped Opportunity

Cost Savings through Recycling

Recycling copper yields significant cost savings compared to mining and smelting raw copper. Recycling 1 ton of copper saves around 3 tons of coal which is used to power copper smelting. It also saves 85% of the energy required to produce new copper from raw materials. Recycled copper production emits only 35% of the carbon dioxide and 90% less sulfur dioxide compared to primary copper production. Recycling used copper wires, cables, pipes and other items reclaims a valuable resource and prevents copper from being dumped in landfills.

Growing Demand for Secondary Copper

As world copper resources deplete Recycled Copper will play a larger role in meeting rising demand. Global copper demand is projected to increase by 40% over the next decade driven by growth in renewable energy, electric vehicles and electronics sector. Much of this incremental demand will have to be met through increased copper scrap recycling rather than mining new supplies. Secondary copper production currently accounts for around one-third of global refined copper supply and this share is expected to rise going forward. Recycling keeps valuable materials in use and prevents depletion of finite natural resources like copper.

Copper Recycling Processes and Techniques

 
There are well established processes to collect, sort and recycle copper scrap into new products. The key steps involve separating copper-containing scrap from other materials, shredding large pieces, sorting scrap by type and purity, removing other metals and refining into high purity copper through physical and chemical processes. Metals in alloy scrap can also be recovered through pyrometallurgy which involves high temperature melting and vaporization. New technologies like sensor-based sorting help improve purity and increase recycling rates. Automated sorting machines now detect even small copper pieces which were earlier missed.

Collection and Logistics Challenges

One of the main challenges in boosting copper recycling is systematically collecting all post-consumer scrap. Currently, a significant part of the estimated 25 million tons of global copper scrap generated annually gets landfilled or lost due to inadequate collection infrastructure. Setting up separate bins and designated collection points can boost scrap recovery rates. Improving scrap transportation logistics through dedicated routes and transfer stations helps recyclers economically aggregate smaller scrap volumes. Municipalities and waste handlers need incentives to prioritize copper scrap recovery. Producer Responsibility regulations make manufacturers responsible for collecting post-consumer scrap.

Importance of Scrap Grades and Quality

 
Maintaining high purity and consistency of recycled copper grades is important to maximize value and re-usability. Major scrap categories like new scrap, old scrap, mixed low grade scrap have distinct applications, recovery rates and selling prices depending on their copper content and purity. Contamination lowers copper recovery and increases refining costs. Recent industry-led initiatives are standardizing sorting and grading practices to bring more transparency to scrap markets. Recyclers are incentivized to carefully segregate top grades, which can substitute primary copper in most applications. Tighter specifications help bolster demand for secondary copper.

Role of Public Policy in Promoting Recycling

 
Governments across regions have implemented various policy measures to boost copper recycling. Promoting extended producer responsibility makes manufacturers responsible for recycling their post-consumer products. Strategies like landfill bans prevent useful materials from being wasted. Legislative targets and subsidies encourage collection and recycling infrastructure investments, especially in developing markets. Trade policies promote exports of high-grade scrap to regions with surplus secondary smelting capacity. Regulations on mining and primary smelting help level the playing field for recycled copper. Public procurement preferences and green building certifications create stable demand for secondary copper. Stringent end-of-life regulations on e-waste will be a game changer.

Outlook

Rapidly depleting geological copper reserves and peak copper production expected within this decade, recycling copper achieves economic and environmental sustainability. Expanding collection networks and maintaining scrap quality will ensure stable supply of secondary copper to meet over 40% rise in projected demand in the coming years. While scaling up recycling faces challenges, a circular copper economy offers multiple benefits if the right public-private collaborations are enabled. Certainty in scrap offtake and policy support will attract more investments and help realize recycling's vast untapped potential.
