The exhibition project titled "Research and Application of Technology and Equipment for Full-Chain Resource Utilization of Aluminum Waste," spearheaded by Professor Fengting Li's team from CESE, secured the Gold Award at the 50th Geneva International Exhibition of Inventions. This project introduced and implemented three innovative processes for aluminum ash resource utilization: firstly, utilizing aluminum dross hydrolysis and denitrification technology to produce high-purity polyaluminum chloride for water treatment agents; secondly, innovatively proposing a waste salt roasting defluorination modification process; and thirdly, combining wet and pyrometallurgical methods to produce polyaluminum chloride water treatment agents from acid-soluble aluminum ash, while utilizing the residual slag for calcium aluminate preparation. This award-winning project has achieved industrial application across multiple provinces and cities, processing over 200,000 tons of aluminum ash in the past three years, reducing carbon dioxide emissions by more than 500,000 tons. It has also obtained 10 Chinese patents and 1 U.S. patent, and was honored with the First Prize for Scientific and Technological Progress from the China Association of Circular Economy for 2024.
