旭化成等四家公司共同启动电解单元与电极金属回收验证

Core Viewpoint - Asahi Kasei, in collaboration with Nobian, Furuya Metal, and Mastermelt, is launching a verification project in 2025 focused on metal recovery from electrolytic cells and their internal electrodes, aiming to establish a metal recycling ecosystem in the chlor-alkali industry to promote resource circularity and sustainable development [1][3]. Group 1: Project Overview - The project involves the recovery of precious metals such as iridium and ruthenium from electrolytic cells, which are in increasing demand due to the rising needs in battery and electronic components, as well as applications in hydrogen production technologies [3]. - The collaboration will start with Asahi Kasei recovering end-of-life electrodes from Nobian, followed by Mastermelt and Furuya Metal extracting and processing catalysts for further refinement and purification of precious metals [3]. Group 2: Industry Implications - This initiative aims to extend transactions between end-users and suppliers across the chlor-alkali industry, establishing a stable supply ecosystem for electrolytic cells and electrodes [4]. - The project will enhance traceability and visibility within the ecosystem, accelerating the adoption of recycled precious metals in electrolytic cells and electrodes, and Asahi Kasei plans to apply related technologies to the green hydrogen production field [4].
