Can titanium be recycled? The answer is yes. In the chlor-alkali industry, wastewater treatment plants, metallurgical factories, and chemical industries, titanium plates have become a key material due to their excellent corrosion resistance. Titanium is one of the few metals that can be recycled indefinitely without losing its performance. Many companies worldwide have established closed-loop recycled systems for titanium, particularly in the aerospace and medical fields, where a 100% recycle policy for titanium waste is being enforced. Titanium recycling technology is now mature, enabling efficient recovery of discarded anodes from the chlor-alkali industry, filters from wastewater treatment plants, and reactor linings from metallurgical plants. Recycled titanium exhibits performance identical to that of virgin titanium.
Almost all forms of titanium materials in the industrial sector can be recycled. This includes titanium plate scrap, turning chips, scrap heat exchanger tubes, reactor linings, and discarded titanium electrodes. In wastewater treatment plants, replaced titanium filters and supports are ideal recycle materials. Aerospace-grade titanium alloys (such as Ti-6Al-4V) have the highest recycle value, with their recycled titanium ingots directly usable in high-end manufacturing. Waste titanium powder from 3D printing in the medical field is also highly valuable. Can titanium be recycled? Even titanium materials with an oxide layer on the surface can be processed using appropriate technologies. Germany's Sicon Company's pressing technology can control the oxygen increase in titanium shavings to below 0.1%.
Industrially, two main methods are used to recycle titanium: smelting and solid-state methods. How to recycle titanium? Hydrogen plasma smelting (HPS) is an emerging technology. Increasing the arc power can simultaneously optimize the melt pool temperature and the concentration of active hydrogen species, reducing oxygen content to below 1,000 ppm within 8 minutes. The tensile strength of recycled TC4 alloy can reach 882 MPa, outperforming traditional cast titanium alloys. How to recycle titanium? Salt electrolysis is another green technology with the advantages of low cost and high product purity. At a voltage of 1.9 V, the electrolysis efficiency can reach 80%, with product purity of 99.95% (4N5). How to recycle titanium? For titanium scrap, a press machine is typically used to process it under ultra-high pressure of 80 MPa with argon gas protection.
Practical applications have proven that recycled titanium performs no worse than virgin titanium. A certain aviation engine manufacturing company reduced the melting loss rate from 30% to below 10% after using a briquetting machine. Recycled titanium ingots are directly reintroduced into high-end manufacturing processes, truly achieving “turning waste into treasure.” Titanium is recyclable, and the market for recycled titanium is growing rapidly. The global titanium recycle market size is expected to exceed 1 billion USD by 2025, with an annual compound growth rate of over 12%. In the chlor-alkali industry, recycled titanium plates are reprocessed into electrolytic cell components; in the chemical industry, they are made into reaction vessel linings; in wastewater treatment plants, recycled titanium is used to manufacture corrosion-resistant filtration systems.
There are several specialized companies worldwide that recycle industrial titanium scrap. EcoTitanium in Europe specializes in recycle aerospace-grade titanium scrap, producing titanium ingots with up to 75% recycled content, which are reused in production for various Airbus aircraft models. IPX in the United States has announced plans to build the world's largest 100% titanium scrap recycling plant by 2025, with an annual production capacity of 1,125 tons, exclusively using titanium scrap as raw material. Where to recycle titanium? Many large titanium material manufacturers also offer recycle services. Major global manufacturers such as TIMET and HONGKONG precious metal recyclers. all have recycled operations. These companies typically require titanium scrap to be sorted by grade and form to ensure recycled efficiency and quality.
