Copper scrap recycling: driving green metallurgy transformation of the “urban mine” new opportunities

[Introduction] Under the dual drive of global carbon neutrality and 

resource recycling, copper scrap recycling is leaping from the 

traditional recycling industry to a strategic pillar of the modern 

metallurgical industry.

First, the three core values of copper scrap 

recycling industry chain

Significant resource substitution effect

The proven reserves of global copper resources can only meet the 

demand for the next 40 years, and the amount of copper scrap 

resources generated through cables, electronic equipment, building 

components, etc. exceeds 20 million tons per year. Recycling 1 ton 

of copper scrap is equivalent to mining 150 tons of primary ore 

and reducing energy consumption by 85%. This “waste to treasure”

 conversion efficiency makes copper scrap a “buffer” to 

stabilize the copper supply chain.

Outstanding economic benefits

Compared with traditional copper smelting, copper scrap recycling 

can reduce processing costs by 40-60%. Without going through 

the mining and beneficiation process, the production path directly

 into the refining process can shorten the return on investment 

cycle by more than 30%. Especially in electrolytic copper processing, 

the energy consumption of recycled copper scrap is only 25% of 

that of virgin copper, which shows a stronger anti-risk ability 

in the fluctuation of energy prices.

Effective in environmental protection and emission reduction

The emissions of modern copper scrap melting process are 

reduced by 70% compared with the traditional process, of 

which the reduction of sulfur dioxide is more than 85%. The 

dust capture efficiency of the pretreatment system exceeds 

98%, and the wastewater recycling rate exceeds 95%. This 

cleaner production model, so that the recycled copper 

enterprises are more likely to meet the increasingly 

stringent environmental standards.

Second, intelligent technology reconfiguration 

of renewable copper industry pattern

In the wave of automation in the non-ferrous industry, the field of 

copper scrap recycling is experiencing a technological revolution:

Intelligent sorting system: X-ray fluorescence spectroscopy (XRF) and 

near infrared (NIR) technology is used to realize a sorting speed of 5 

pieces per second, with copper purity identification accuracy of 99.7%.

Melting process upgrading: Regenerative Thermal Oxidation (RTO) 

technology with oxygen-enriched combustion increases the thermal 

efficiency to 82% and reduces the energy consumption per ton 

of copper to 380kW-h.

Digital management: IoT platform monitors 300+ production 

parameters in real time, and big data model predicts fluctuations 

in raw material composition and guides dynamic adjustment of 

process parameters.

These technological innovations have boosted the qualified rate 

of recycled copper from 92% to 98%, reduced processing costs 

by another 15%, and built a technological moat for the industry.

Opportunities and challenges for industrial upgrading

Policy dividends continue to release:

The EU will use the proportion of recycled metal into the carbon 

tariff accounting system.

E-waste producer responsibility extension system implemented in 

30+ countries worldwide

Market space accelerated expansion:

The copper recycling cycle in the construction field has entered an 

intensive period, and it is expected that the global decommissioned 

construction copper will reach 8.5 million tons in 2025; the new 

energy industry has given rise to emerging recycling scenarios 

such as power batteries and photovoltaic components, which will 

create a new market of hundreds of billions of dollars.

Fourth, the future direction of evolution 

under the circular economy

Vertical integration of industrial chain

Build a three-tier system of “recycling network - pretreatment

 center - recycling plant” to form a closed-loop supply chain with 

a radius of 100 kilometers. Realize the integration of logistics, 

capital flow and information flow through the Internet of Things 

platform, and compress the turnover cycle of raw materials 

to within 72 hours.

High-end product transformation

Developed copper alloy precision casting technology to 

break through high-end application scenarios such as 

aerospace and semiconductor. Conductivity of recycled 

copper rods exceeded 101% IACS, reaching military-grade standards.

Carbon asset value realization

Through carbon footprint certification, we have realized 4.2 

tons of CO₂-equivalent emission reduction per ton of recycled 

copper, and formed a new profit point by connecting to the 

carbon trading market.

Accelerating globalization

Southeast Asia is forming a copper scrap distribution center with 

an annual processing capacity of 3 million tons, and the dismantling 

market of retired industrial equipment in Europe and the United 

States is growing at an annual rate of more than 15%, which has 

given rise to new opportunities for cross-border supply chain 

service system.
