Used aluminum beverage cans (UBC) are able to be recycled into can body material (JIS3004) by remelting. However, in these remelting processes, such problems attributed to "paints" occur as unfavorable molten metal composition (primarily titanium) and lowering of molten metal yield. Consequently, for promoting recycling of aluminum UBC, removal of these "paints" is essential, and the paints have been removed by thermal or mechanical methods. This paper reports the development of a swell-peeling method in which paints are chemically removed. It also reports that the swel-peeling method successfully prevents the impurity element titanium from contaminating the molten metal and improves the molten metal yield simultaneously, ensuring the good possibility of promoting recycling of aluminum UBC.
