摘要： A sustainable materials management for metals should be achieved to conserve resources of metal minerals. For the sustainable materials management, material flows through the whole life cycle of materials have been recognized by material flow analysis (MFA) studies. Former MFA studies pointed out that cyclic use of metals could be enhanced not only by increasing quantity of recovered scrap but also by upgrading quality of the scrap. In general, the quality is degraded by contaminants which commingle at disassembling processes. The mixture of contaminants depends on usage of materials in products. Here, Type I ecolabelling has a potential to convey messages for avoiding mixture of contaminants to the producers of finished products. In this study, on the basis of a survey on existing certification criteria related to metals in the world, a general concept of certification criteria on sustainable materials management for metals in Type I ecolabelling system is proposed. Finally, we propose six criteria in the form of certification criteria in Type I ecolabelling system.
