The purpose of this study is to identify the materials flow of aluminum cans from its production, manufacturing, distribution, consumption to its discarding, while finding problems in the materials flow diagram in carrying out recycling, and to present improvement measures for relevant systems and policies. Through various statistics, it was found that the actual amount of aluminum ingots distributed in Korea is 1,808,597 tons. From this 381,802 tons of aluminum plates were used for domestic uses, 75,070 tons were used to produce cans, and it was found that 50,073 tons of can products were produced and distributed in Korea. The 50,073 tons of wastes for separate collection was 96% and recycling was 76% for a total of 38,297 tons for recycling. Upon examining the recycling path, it was found that can-to-can was 35% equivalent to 13,403 tons, while 14,100 tons were melted for alloys and 10,794 tons were used as deoxidizing agents for blast furnaces. According to such studies, a materials flow diagram was drafted and the problems in recycling for each stage were reviewed. In result, plans to improve packaging materials and structures in the production stage, plans to restrict inclusion of foreign particles in the discard and selection stage, plans to provide different support in funding and granting quality ratings in the sorting and compression stages, and plans to apply as recycling designated business systems for high-value recycling in the resourcing stage were proposed.
