Recycling Titanium, Nickel, and Other Rare Metals to Achieve Resource Security and Carbon Neutrality

Specialty metals such as titanium, nickel, cobalt, molybdenum, and tungsten are essential to Korea’s aerospace, defense, semiconductor, and nuclear industries. These high-performance metals are prized for their strength, corrosion resistance, and heat tolerance.

However, the global supply of these materials is structurally limited. Their scarcity in the Earth’s crust, limited processing sites, and reliance on imports expose Korea to supply chain vulnerabilities. In this context, recycling specialty metal scrap emerges as a national strategy to strengthen resource security and reduce carbon emissions.


The Specialty Metal Recycling Process

The recycling process involves several technical steps:

1. Scrap recovery and sorting: Chips, powders, cutting remnants, and off-spec parts are categorized based on impurity levels and metal composition.

2. Refining and remelting: Technologies such as Vacuum Arc Remelting (VAR), Plasma Arc Melting (PAM), and Electron Beam Melting (EBM) are used to remove impurities and restore high-purity alloys.

3. Reprocessing into usable alloy materials: These refined materials are ready for use in melting and casting without additional alloying.

In particular, nickel-based superalloys and titanium alloys demand extremely high purity. The precision of the recycling process directly determines product quality.


Economic and Environmental Benefits of Recycling

Recycling rare metals reduces production costs and mitigates dependence on volatile global markets. For example, recycling titanium scrap instead of producing sponge titanium can cut costs by 30–40%.

The environmental benefits are even more critical. Titanium scrap recycling reduces CO₂ emissions by over 90% compared to mining and smelting. This is vital in meeting carbon border tax regulations and ESG standards set by the EU, U.S., and South Korea.

Recycling supports Korea’s transition toward a resource-circulating economy while reducing industrial waste and import dependency.


Global Trends and the Need for Korean Action

Advanced economies like Japan, the U.S., and EU countries are rapidly developing scrap collection systems and recycling technologies. They are also introducing scrap certification systems by industry, helping to standardize quality and stabilize circulation.

Korea must follow suit. Dong-A Special Metals plays a key role in this transition by refining and reprocessing titanium and nickel scrap into high-purity alloy feedstock. Our technologies ensure lower lead times and improved resource efficiency, benefitting domestic industries including CNC manufacturers, cutting tool makers, and aerospace suppliers.

The time has come to foster Korea’s specialty metal recycling ecosystem. Recycling is no longer just about reducing costs—it’s a critical industrial strategy that supports carbon neutrality, resource independence, and long-term competitiveness.
