Aluminium recycling is becoming an increasingly important part of the global aluminium supply chain as more end-of-life material becomes available, sorting technologies improve and downstream industries place greater emphasis on lower-carbon and higher-specification materials.
Data from the World Bureau of Metal Statistics (WBMS), reported by Shanghai Metals Market (SMM), shows that global recycled aluminium production reached approximately 12.95 million tonnes in the first half of 2026, compared with 36.02 million tonnes of primary aluminium output over the same period. In other words, recycled aluminium production was equivalent to roughly 36% of primary aluminium output, highlighting the scale that secondary metal has already reached within the industry.
The next stage of growth, however, will depend not simply on having more scrap available, but on how effectively the industry can collect, sort, recover and return aluminium to high-value applications.
A Larger Scrap Pool Is Taking Shape
End-of-life vehicles are becoming an increasingly important source of recyclable materials.
China's vehicle trade-in programme has already driven the scrapping and recycling of more than 8 million older vehicles, according to the Ministry of Commerce. Separately, industry reporting indicates that close to 10 million vehicles reach scrapping age each year in China, illustrating the scale of the future material stream.
The shift towards new energy vehicles is also changing the material composition of future end-of-life vehicles. Aluminium is increasingly used in body structures, battery enclosures, chassis components and other lightweight applications, meaning that newer vehicle generations could eventually provide a larger pool of recoverable aluminium when they reach end-of-life.
Solar photovoltaic systems represent another long-term source of secondary material.
According to the International Aluminium Institute (IAI), around 8 million tonnes of aluminium were used in global PV manufacturing in 2024. The IAI projects total cumulative end-of-life PV material—not aluminium alone—to reach around 1.7 million tonnes by the early 2030s, increasing sharply to 60–78 million tonnes by the 2050s.
This distinction is important: the 60–78 million tonnes refers to the total projected PV waste stream. Nevertheless, because aluminium is widely used in PV frames and supporting structures, improving dismantling and material separation will be critical to recovering its value. The IAI also notes that design choices such as mechanical fasteners can significantly improve end-of-life aluminium recovery compared with adhesives or difficult-to-separate composite structures.
Sorting Technology Is Raising the Value of Scrap
As scrap volumes increase, the ability to identify and separate different alloys is becoming increasingly important.
German aluminium producer TRIMET is preparing to launch a new aluminium scrap sorting facility at its Hamm site. Scheduled to begin operation in late 2026, the facility will use laser-induced breakdown spectroscopy (LIBS) to analyse the metallurgical composition of scrap and separate material into alloy-specific fractions. TRIMET says the investment is intended to strengthen closed material loops, increase recycled content and improve control over secondary raw-material quality.
Industry reports indicate that the system will have an annual sorting capacity of around 40,000 tonnes and can analyse up to 150 scrap pieces per second, identifying alloying elements including silicon, copper, iron and magnesium before directing material into the appropriate fractions.
A similar emphasis on sorting and recovery can be seen in China. According to Asian Metal, Quantum Digital New Materials Co., Ltd., a subsidiary of Hebei Shengzhuo Group, commissioned a 150,000-tonne-per-year rare-earth aluminium alloy project in August 2026. The facility incorporates LIBS-based intelligent sorting and twin-chamber reverberatory furnaces. Asian Metal reports a metal burn-off rate of approximately 0.6% and aluminium recovery of more than 95% from dross.
These examples reflect a broader transition from simply recovering aluminium scrap towards alloy-specific sorting, improved metal yield and higher-value recycling.
Lower-Carbon Aluminium Is Gaining Commercial Importance
The environmental case for aluminium recycling remains strong.
IAI data indicates that producing recycled aluminium requires around 95% less primary energy than producing primary aluminium. It also results in substantially lower greenhouse-gas emissions, although lifecycle comparisons depend on the system boundaries used in each assessment.
Carbon regulation is adding another commercial dimension.
The EU's Carbon Border Adjustment Mechanism (CBAM) entered its definitive regime in 2026. Aluminium is among the covered sectors, and the European Commission published CBAM certificate prices of EUR 75.36/tCO₂e for Q1 2026 and EUR 75.28/tCO₂e for Q2.
For aluminium, however, it is important not to equate the full lifecycle carbon advantage of recycling directly with CBAM certificate costs. Under the current definitive-phase rules, CBAM calculations for aluminium focus on direct embedded emissions, while indirect electricity emissions are not yet included in the same way.
Even so, CBAM is increasing the commercial importance of verified emissions data, traceability and lower-carbon production routes in international aluminium trade.
Recycled Aluminium Is Moving into Higher-Value Applications
Demand for recycled aluminium is also moving beyond traditional secondary-alloy applications.
One recent example is Xiaomi Titan Alloy 2.0. Xiaomi states that the alloy is produced from 100% post-consumer recycled aluminium and has entered mass production for integrated die-cast automotive rear-floor structures. According to Xiaomi, the material achieves a carbon footprint of 1.1 kg CO₂e/kg, approximately 93% below the primary aluminium benchmark used in its assessment, with the footprint independently calculated by IVL Swedish Environmental Research Institute under the International EPD system.
The development illustrates how recycled aluminium is moving into demanding structural automotive applications where material performance, casting quality and carbon data must all meet strict requirements.
The semiconductor supply chain is another emerging area. SuperAlloy Industrial has outlined plans to recover high-purity aluminium generated in technology manufacturing processes and reintroduce the material into semiconductor consumables and equipment components. The initiative remains an expansion programme rather than evidence of widespread commercial adoption, but it points to the growing interest in recycled aluminium for increasingly specialised applications.
