As shown in FIGS. 1 and 2, beverage cans such as aluminum cans and steel cans collected in a loose state after being served for drinking are charged into a reduction furnace 1 such as an induction heating furnace. Before that, it goes through necessary pre-processing steps. This pre-treatment process includes removing foreign objects (bottles, metal boxes, etc.) other than steel cans and aluminum cans, and beverage cans with a considerable amount of remaining contents, and putting beverage cans into a light press machine. Press, light pressing, for example, crushing to about 1/3 volume, or, in the case of a steel can that has already been magnetically selected elsewhere and pressed into a block, a light pressing press There is a process in which a crusher is installed before the block-shaped material is divided into compressed, rose-shaped steel cans. When a predetermined amount of beverage can has been charged into the reduction furnace 1, the lid is closed and N 2 gas or CO 2 gas is blown appropriately to keep the atmosphere in the furnace non-oxidizing (or weakly oxidizing). Purge oxygen. In this state, induction heating is started, and the beverage can is rapidly heated in the range of 350 ° C to 700 ° C.

The reason why the temperature is set to 0 ° C. to 700 ° C. is that if the temperature is lower than 350 ° C., it is difficult to completely separate the steel part and the aluminum part of the can. Exceeding it, and wastes energy consumption.
The above range was set. It is also advantageous to keep the beverage can at a high temperature during the subsequent crushing and granulation.
In the heating step in this range, organic substances such as paint and coating material on the surface of the can are vaporized or decomposed.

い。In the reduction furnace 1, organic substances such as paints and coatings on the surface of the can are decomposed and gasified. In the present invention, this gas is taken out of the furnace and guided to the cooling / washing tower 2, where water is removed. To cool the gas and liquefy the gaseous organic matter. In the cooling / washing tower 2, a mixed emulsion of liquefied organic matter and washing water is generated. This emulsion is introduced into the oil / water separation tank 3, and the liquid phase is allowed to stand for a certain period of time, so that the organic matter of various components is obtained. Oil mixture (oil mixture) and washing cooling water to recover the oil mixture. It is desirable to provide a means for distilling the mixed oil to separate and recover a specific organic compound.

ことができる。As shown in FIG. 1 and FIG. 2, after the beverage can is heated and decomposed by the organic matter contained in the beverage can, in the furnace, the steel part and the aluminum part are separated by a difference in their thermal expansion coefficients. However, the beverage cans are taken out of the reduction furnace 1 and loaded into the next crushing or crushing / pelletizing apparatus 5 to apply a mechanical impact force or the like. Then, it is crushed into chips or granulated into pellets at the same time as crushing, but at this time, the steel part and the aluminum part are completely separated in this step and are individually chipped or granulated. . At the same time, in this separation step, inorganic substances of metal compounds such as metal oxides attached to the surface of the can can also be separated.
This mixed inorganic substance can also be separately collected and used as a metal resource.

ば、いかなる形式のものでも採用できる。An induction heating furnace suitable for use as a reduction furnace is a system in which a furnace body is made of a non-conductive material such as ceramics and heat is generated by generating heat in a steel can itself by electromagnetic induction. The use of the low-frequency type is optimal because the heating time of the steel can is short and the set temperature can be easily changed. However, the present invention is not limited to this type of induction heating furnace, an induction heating furnace using a conductor for the furnace body, a heating furnace of an electric resistance heating method, or a furnace that is heated from the outside with a fossil fuel or the like,
Even if it is a method of heating by radiation or heat conduction, any method can be used as long as the inside of the furnace can be heated to a predetermined temperature and a non-oxidizing atmosphere (or a weakly oxidizing atmosphere) can be maintained. Can be adopted.

となる。The effects obtained by the present invention are as follows. (1) Along with the recovery of high-quality steel and aluminum, paints and coating materials for can bodies, which were not neglected in the past, are also used as mixed oils, and mixed metal compounds adhering to the heated can surface are also collected as necessary. It is possible to collect useful resources from almost used beverage cans without waste, thereby further improving the effective use of resources and the effect of recycling. (2) Since the beverage can is heated in a non-oxidizing (or weakly oxidizing) atmosphere, the material, especially aluminum, is not oxidized, and can be heated at a high temperature. Therefore, the steel part and the aluminum part can be reliably and easily separated, and high-quality steel and aluminum can be recovered. In addition, the gasification or decomposition of organic substances can be reliably performed, and the recovery of oily substances can be facilitated. .
