Rewritten Summary: China’s Beverage Can Sector Pursues Unified Alloy for Greener Recycling and Lightweighting   China’s aluminium beverage can industry is developing a new aluminium alloy to simplify circular recycling and advance the sector’s green transition, according to Huang Ruiyin, chief researcher at the Chinalco Materials Application Research Institute based in Beijing.   Currently, beverage can bodies are typically made from 3104 alloy while can ends use 5182 alloy — two materials with distinct compositions and properties that complicate closed-loop recycling. The ongoing research targets a new end alloy with a chemical makeup close to that of can body stock, aiming to enable a single 3104-type alloy for entire cans. Huang noted this design would retain strong service performance, meet recycling requirements, and deliver a lower total societal cost than the existing 5182 alloy, adding that the whole industry chain must collaborate to roll out this “uni-alloy” solution.   Market scale and output   Huang shared 2025 industry data showing continued demand growth in China:   - Global aluminium can stock consumption surpassed 8 million tonnes, including 6 million tonnes of body stock and roughly 2 million tonnes of end and pull-tab stock. - China produced 2.4 million tonnes of beverage can aluminium alloy last year, with domestic demand accounting for around half: 800,000 tonnes of body stock and 400,000 tonnes of end stock. - Domestic manufacturers turned out 75 billion can bodies and 150 billion can ends to meet market needs.   Higher scrap use for lower carbon footprint   Raising recycled scrap content is a key pathway to decarbonisation, as remelted scrap consumes only 5% of the energy and generates only 5% of the carbon footprint of primary aluminium ingots. However, this requires alloy formulations with higher impurity tolerance, strict melt quality control, and the development of pre-treatment systems paired with dual-chamber furnace technology.   Elevated scrap input also raises iron (Fe) levels. Huang explained that the ratios of iron, manganese and silicon strongly influence second-phase formation, so the final alloy composition must maximise α-phase fraction to support second-phase fragmentation. Process-wise, dual-chamber furnace melting cuts oxidation loss to below 1%, while inline degassing and filtration keep slag and hydrogen content in check.   Advanced domestic manufacturing capabilities   China’s major canstock producers — Chinalco, Nanshan, Zhongfu, Xiangyu, Hongfa and Yongjie — are generally equipped with state-of-the-art melting and casting facilities, ensuring high melt quality and mature scrap recycling capacity.   - On hot rolling lines, thickness tolerance is within ±20 μm for 5182 alloy and ±10 μm for 3104 alloy. Automatic temperature control limits coil-wide temperature variation to within ±10°C during stable rolling, and some mills deploy online surface inspection systems for real-time quality monitoring. - On cold rolling lines, mass-flow thickness control keeps deviation within ±3 μm. Standard can body gauge has fallen to 0.240 mm, with export-grade products reaching 0.235 mm.   Lightweighting and performance improvements   Beyond alloy development, the industry is advancing lightweighting through process and design optimisation:   - Better melt quality, tighter thickness tolerance and improved strip profile reduce earing during cupping. Secondary forming of can bottoms creates reinforcing ribs that allow further gauge reduction. - Beverage end stock has reached 0.208 mm in standard gauge, with some products as thin as 0.203 mm. Revised end profile designs can enable further thinning. - After baking, the material achieves a yield strength of 330–360 MPa, improving strength retention after the baking process and reducing pressure-resistance degradation.   Industry outlook   Aluminium’s excellent sealing performance, high thermal conductivity and infinite recyclability give it strong competitive edges in metal packaging, with promising growth prospects. He called for joint efforts from upstream and downstream enterprises to continuously drive aluminium packaging toward lightweight and green development.

Beverage can manufacturer Royal Can Making Co is evaluating a closed-loop water recovery system for its canmaking operations in Iraq.     Speaking at the Canmaker Summit in Shanghai, China, Chirine Hamaied, Royal Can’s world-class performance manager, told delegates that as part of the company’s sustainability roadmap, it is working on a waste-water recovery pilot with a yet unnamed China-based company.   Beverage can plants, of which Royal has two sites, use water to clean D&I aluminium cans in the manufacturing process.   “In this project, we are evaluating a closed-loop water recovery system that treats water and returns the recovered water into manufacturing,” she explained. “Currently, we are evaluating the technical feasibility, the recovery performance, and operating costs.”   Hamaied spoke about Royal Can’s success with some of its recent sustainability initiatives for waste water, including its Sludge Cake initiative, which converts waste water into solid material. It is produced during waste water treatment after removing contaminants from the process water. The waste is then converted into solid bricks for easier handling.   “We carefully treat our wastewater using five chemicals to penetrate against the government’s water quality standards,” she continued. “Why we needed a better solution? This question was raised at the initial phases of the project, and many points were raised. One of the points is that Sludge Cake can become a useful resource instead of a waste. This is why we have to move away from traditional landfilling. We have a clear objective, which is 0% landfill, 100% divergent through sustainable alternatives.”   Instead of relying on a single option, Royal Can developed two: cement co-processing and eco-blocks manufacturing. The former was the first and primary route, as it is an internationally recognized solution in which wastewater is converted into sludge as a resource for cement production. For this, the company partnered international company Lafarge.   The second route, eco-block manufacturing, sees sludge cake converted and used in the manufacturing of blocks. “For this application, sludge cake is crushed and blended with cement and other block-making materials. Different choices were tested at the beginning in order to find the mixture that provides both environmental value and acceptable structural performance.   Royal Can Making Company  is now working on its closed-loop water recovery system, which it hopes will be operational in 2027.   “These initiatives all come together under one bigger role, which is our objective of creating a long-term environmental legacy. Our meter for success is not how many lines we add, how many cans we produce, or how much energy we produce. Rather, it’s how harmless the production process is done, and how responsibly we produce.”
