The State of Copper Recycling in the U.S.

The State of Copper Recycling in the U.S.
Copper is essential for a low-carbon economy due to its crucial role in renewable energy technologies.
As a result, many worry that a lack of the metal used in wires and batteries can hurt a transition to a green economy.
In this graphic, our sponsor, the Copper Development Association, explores how recycling can address the demand for copper.
Copper Scrap Recycled in the U.S.
In 2022, the total copper scrap recycled in the U.S. was approximately 830,000 tonnes, equivalent to 32% of the total U.S. copper supply for the same period. Around 670,000 tonnes (81%) originated from pre-consumer sources generated during manufacturing operations, while 160,000 tonnes (19%) came from post-consumer sources, such as obsolete products.
Brass and wire-rod mills accounted for the majority of the copper recycled from scrap (85%). Additionally, smelters, refiners, and ingot makers make 10% and chemical plants, foundries, and other manufacturers around 5%.
| Copper from Scrap | 2022 Content (tonnes) |
|---|---|
| Brass and wire-rod mills | 650,000 t |
| Smelters and refiners | 40,000 t |
| Ingot makers | 39,500 t |
| Foundries, Other | 40,000 t |
Despite the rising demand for copper, the U.S. predominantly exports its copper scrap.
In 2022, the U.S. exported half of the 1,569,000 tonnes of the copper content generated from scrap. This export trend persisted because, until recent years, the country lacked operating secondary copper smelters capable of processing complex scrap grades into furnace-ready raw materials.
However, reshoring this metal presents an opportunity for the country.
Tapping into the Urban Mine
North America currently has about 86 million tonnes (Mt) of copper in use, known as the Urban Mine. This copper will become available for recycling as aging infrastructure and products reach the end of their service lives:
- Buildings: 45.4 Mt
- Infrastructure: 16.1 Mt
- Consumer Products: 11.2 Mt
- Transport: 8.5 Mt
- Industrial Uses: 4.8 Mt
Increased secondary smelting and refining capacity is a crucial building block for a more resilient and self-sufficient U.S. copper supply chain.
In response to the growing need for copper, the U.S. plans to add over 280,000 tonnes of secondary smelting and refining capacity in the next few years. This expansion will enable the country to process more complex scrap grades domestically.
Given that copper products can last for decades, creating a lag time before the material becomes available for recycling, primary production will continue to play an important role in meeting the increasing needs in the U.S.

Charted: The End-of-Life Recycling Rates of Select Metals
End-of-life recycling rates measure the percentage of a material that is recovered at the end of its useful life, rather than being disposed of or incinerated.
Charted: The End-of-Life Recycling Rates of Select Metals
This was originally posted on our Voronoi app. Download the app for free on Apple or Android and discover incredible data-driven charts from a variety of trusted sources.
We visualize the end-of-life recycling rates (EOL-RR) of commonly used metals in the economy. Data is sourced from the International Energy Agency, last updated in 2021.
Tracking recycling rates helps manage resources better and make smarter policies, guiding efforts to cut down on waste.
Ranked: The End of Life Recycling Rates of Select Metals
Gold has an 86% recycling rate according to the latest available data. Per the Boston Consulting Group, one-third of total gold supply was met through recycling between 1995–2014.
| Metal | End-of-life recycling rate (2021) | 🔍 Used In |
|---|---|---|
| Gold | 86% | 💍 Jewelry / Electronics |
| Platinum/Palladium | 60% | 🔬 Optical fibers / Dental fillings |
| Nickel | 60% | 🔋 Batteries / Turbine blades |
| Silver | 50% | 💍 Jewelry / Mirrors |
| Copper | 46% | 🔌 Electrical wiring / Industrial equipment |
| Aluminum | 42% | ✈️ Aeroplane parts / Cans |
| Chromium | 34% | 🍽️ Stainless steel / Leather tanning |
| Zinc | 33% | 🔗 Galvanizing metal / Making rubber |
| Cobalt | 32% | 🔋 Batteries / Turbine engines |
| Lithium | 0.5% | 🔋 Batteries / Pacemakers |
| REEs | 0.2% | 📱 Mobile phones / Hard drives |
Note: Figures are rounded.
Several factors can influence metal recycling rates. According to this International Resource Panel report, metals that are used in large quantities (steel) or have a high value (gold) tend to have higher recycling rates.
However, for materials used in small quantities in complex products (rare earth elements in electronics), recycling becomes far more challenging.
Finally, a metal’s EOL-RR is strongly influenced by the least efficient link in the recycling chain, which is typically how it’s initially collected.

Key Takeaways
- Half of the world’s fossil fuel and cement carbon dioxide emissions in 2023 came from just 36 entities, according to a report by the Carbon Majors Project
- If Saudi Aramco were a country, it would be the fourth-largest polluter in the world, after China, the U.S., and India.
- Five publicly traded oil companies—ExxonMobil, Chevron, Shell, TotalEnergies, and BP—together accounted for 5% of global carbon dioxide emissions from fossil fuels.
Chinese Companies Dominate the List
This graphic is based on Carbon Majors, a database of historical production data from 180 of the world’s largest oil, gas, coal, and cement producers representing 169 active and 11 inactive entities.
In 2023, the top 20 highest carbon-producing entities were responsible for 17.5 gigatonnes of carbon dioxide equivalent (GtCO₂e) in emissions, accounting for 40.8% of global fossil fuel and cement CO₂ emissions.
