Titanium recycling is the process of converting scrap titanium and titanium alloys back into usable titanium metal through processes such as remelting and refining. The core economic value of titanium recycling stems from the precious metals contained in titanium anode grids, titanium electrodes, DSA-coated titanium anodes, and high-performance titanium alloys such as GR7 and GR11. Pure titanium scrap has limited value on its own—in March 2026, the purchase price for new scrap from pure titanium sheets in the Japanese market ranged from 320 to 370 yen per kilogram (approximately $4.80 per kilogram)—but titanium anode scrap containing iridium, ruthenium, and platinum coatings can have a recycling value ranging from hundreds to thousands of dollars per kilogram. Titanium recycling returns these precious resources to the production cycle while fully preserving titanium’s specific strength, corrosion resistance, and lightweight properties. The global titanium recycling market is projected to reach $6.3 billion in 2026 and grow to $9.2 billion by 2034, at a compound annual growth rate (CAGR) of 4.7%. The success of titanium recycling hinges on the precise control of oxygen and iron impurities—clean Ti-6Al-4V turnings typically trade at a 65% to 75% discount relative to primary titanium sponge, while contaminated or mixed-alloy turnings can command a discount of over 85%. Due to the difficulty in ensuring traceability, pure titanium scrap has long been unable to be recycled as pure titanium. Titanium recycling spans multiple high-end manufacturing sectors, including the chlor-alkali industry, electrolytic hydrogen production, aerospace, and medical devices. DONGSHENG Precious Metals Recycling covers the full range of titanium anode mesh, titanium electrodes, DSA-coated titanium anodes, and high-performance titanium alloys such as GR7 and GR11. After professional purification, the material purity can reach 90% to 99%, allowing it to be reintroduced into high-end manufacturing sectors such as electroplating, chlor-alkali, seawater desalination, and aerospace.
The chlor-alkali industry is one of the most important application areas for titanium recycling. In salt electrolysis cells, concentrated brine is electrolyzed to produce caustic soda, chlorine, and hydrogen. Because highly corrosive chlorine is generated in the anode chamber, high-purity titanium materials must be used to protect the electrolysis cells. In such applications, pure titanium requires extremely high purity to achieve excellent corrosion resistance and workability. Asahi Kasei has five decades of experience in the chlor-alkali electrolyzer industry, and the electrolyzers, ion-exchange membranes, and electrodes it manufactures are widely supplied to electrolyzer plants worldwide.
A major breakthrough in titanium recovery within the chlor-alkali industry occurred on March 18, 2026. Asahi Kasei, in collaboration with Nippon Steel and Nippon Steel & Sumitomo Metal Corporation, officially launched a pure titanium recovery system for chlor-alkali electrolytic cells. Under this system, pure titanium scrap generated during the production of salt electrolytic cells at Asahi Kasei’s facility in Nobeoka City, Miyazaki Prefecture, Japan, is sorted according to specifications and its traceability is ensured through a digitally managed system. All sorted scrap is recovered by Nippon Steel & Sumitomo Metal Corporation and processed into a form suitable for remelting. A portion of the processed scrap is returned to Nippon Steel as pure titanium feedstock for remelting in electron beam furnaces. Nippon Steel’s electron beam furnace technology enables the remelting of high-purity titanium while maintaining strict quality standards. This titanium recycling mechanism overcomes long-standing challenges related to pollution control, traceability, and processing, shifting pure titanium scrap from traditional downgraded use (as a steel additive) to high-value closed-loop recycling. The three parties plan to further deepen their cooperation to improve the recovery rate of pure titanium and to link this initiative with the closed-loop precious metals recycling project announced in April 2025.
The explosive growth of the electrolyzer market is creating entirely new demand for titanium recovery. The production of electrodes and membrane assemblies for PEM (proton exchange membrane) electrolyzers requires key and expensive raw materials such as iridium, platinum, and titanium. The titanium-based porous transport layers used in PEM electrolyzers must possess excellent corrosion resistance. The CircuPEM project, launched in early 2026 by the Fraunhofer UMSICHT Institute in Germany, aims to achieve up to 100% recycling of titanium and precious metals from PEM electrolyzers. Funded by the European Regional Development Fund, the project is part of the “GreenEconomy.IN.NRW” innovation competition. With the rapid expansion of global green hydrogen production capacity, the large-scale deployment of electrolyzers will generate a significant amount of titanium-containing waste components—including titanium-based bipolar plates, titanium porous transport layers, and iridium-plated titanium anode grids. The titanium matrix in these components can achieve a metal recovery rate of up to 95% through mechanical disassembly and vibrating screening systems. Biometallurgical technology also offers unique advantages for titanium alloy recovery; through the targeted domestication of Acidothiobacillus, titanium recovery rates can be increased from 65% in conventional processes to 82%. The strategic value of titanium recovery in the hydrogen production sector is increasingly recognized by global industry and policymakers—the large-scale deployment of PEM electrolysers will generate massive demand for titanium recovery, and within the electrolysers’ full life-cycle cost curve, the recovery of precious metals and titanium alloys is emerging as a key pathway to reducing total costs.
The United States has the most systematic policy framework for titanium recovery. Titanium has been designated a critical mineral by the U.S. government, and the U.S. Department of Commerce has labeled titanium imports as a national security threat. The Defense Production Act (DPA) serves as the core legal tool for promoting titanium recovery. 6K Additive received $23.4 million in funding from the U.S. Department of Defense under DPA Title III to expand its capacity for the upcycling of high-grade metals, including titanium, nickel, and refractory metals. In April 2026, the U.S. Defense Logistics Agency awarded 6K Additive a $1.95 million Phase II contract through the “Strategic Value Regeneration” program. The Industrial Base Analysis and Sustainment (IBAS) program provided IperionX with a total of $47.1 million in funding, and the U.S. government also transferred approximately 290 metric metric tons of high-quality Ti-6Al-4V titanium alloy scrap to IperionX at no cost. On July 30, 2026, the U.S. President signed an executive order authorizing the U.S. Department of Commerce, pursuant to the DPA, to impose export controls on industrial scrap containing critical minerals. The U.S. Department of Defense explicitly states that “the ideal solution would involve domestic mining, processing, and refining of ore, as well as the recycling of titanium scrap.”
Europe’s titanium recycling policy is centered on the Critical Raw Materials Act (CRMA). The EU imports 4.7 billion euros worth of titanium annually and is heavily reliant on a small number of supplier countries for critical raw materials. The CRMA sets a 2030 target: the EU’s recycling capacity must account for at least 15 percent of its annual consumption. The European Defense Agency (EDA) has selected the “From Chips to Parts: Circularity of Titanium Chips from Machining to Additive Manufacturing” (CHIPART) project to facilitate proof-of-concept for the circular economy in the defense sector. The CHIPART project is co-funded by the EU LIFE Program and the European Defense Agency. The CRM4Defence project is dedicated to establishing efficient and sustainable European supply chains for the recycling of titanium, aluminum, and magnesium, directly contributing to the CRMA’s priorities. European Standard EN 2955:2026 specifies the general requirements for the recycling of titanium and titanium alloy scrap via vacuum remelting or cold-bed smelting for ingot production.
The United Kingdom has decided to replace Russian titanium with recycled materials. A titanium recycling method developed by the British company QinetiQ claims an efficiency of 97 percent. The UK government’s goal is to meet 20 percent of its critical mineral demand through recycling by 2035.
In April 2026, the Japanese government decided to invest approximately 1 trillion yen (about $9.26 billion) through public-private partnerships by 2030 in technology development and facility construction related to the recycling of critical minerals. The closed-loop recycling of titanium in the chlor-alkali process by Asahi Kasei and Nippon Steel is a landmark example of the industrialization of titanium recycling in Japan.
In China, GB/T 45057-2024 “Recycled Titanium Ingots” officially took effect on June 1, 2025, and GB/T 20927-2026 “Recycled Titanium Raw Materials” has also been issued, providing support for the standardized development of the titanium recycling industry.
Titanium recycling relies on advanced remelting and refining technologies to reduce impurities and ensure that the recycled material meets the specifications for high-performance applications. Electron beam melting (EBM) is one of the most effective methods for recycling high-quality titanium alloys; operating in a high-vacuum environment, it can remove volatile impurities such as magnesium and sodium. Nippon Steel’s electron beam remelting furnace technology for industrial-grade pure titanium is a prime example of this approach. Traditional vacuum arc remelting furnaces require a certain proportion of sponge titanium (typically 50% or more) to maintain arc stability, whereas horizontal electron beam remelting furnaces can use 100% scrap as feedstock. Vacuum arc remelting (VAR) is particularly effective at reducing oxygen contamination and maintaining the integrity of titanium alloys during the remelting process; it is often used in conjunction with electron beam melting to produce high-quality titanium ingots. Plasma arc melting (PAM) effectively controls oxygen content and is suitable for high-end titanium recycling. 6K Additive’s UniMelt technology uses microwave-based plasma to convert machining scrap or alloys into high-purity powders for additive manufacturing. Induction melting is used to process low-grade titanium scrap, which is typically reprocessed into titanium-iron alloys for the steel industry.
Electrochemical deoxidation and molten salt electrolysis represent cutting-edge approaches in titanium recovery. Molten salt electrolysis technology can process titanium machining scrap to achieve high product purity at a lower cost, with a recovery efficiency of up to 80%. The one-step hydrogenation-deoxidation process in titanium scrap recovery converts titanium scrap into titanium hydride powder. IperionX’s patented HAMR (Hydrogen-Assisted Metal Thermal Reduction) and HSPT (Hydrogen Sintering Phase Transition) technologies produce high-performance titanium alloys from titanium ores or scrap with lower energy consumption, costs, and carbon emissions. IperionX’s Virginia-based facility uses 100% recycled titanium feedstock for production and aims to achieve an annual production rate of 200 metric metric tons of titanium by the end of 2026. Progress has also been made in titanium scrap recycling within the additive manufacturing sector—unmelted powder from the powder bed fusion process can be recycled to improve material utilization. The electron beam powder bed fusion (EB-PBF) process has been used to repurpose waste L-PBF Ti-6Al-4V powder.
