<p>PROBLEM TO BE SOLVED: To obtain a product which is mainly composed of foil-like aluminum pieces effectively reusable as industrial resources and has a high aluminum content by subjecting aluminum foil composite materials to a dry distillation and carbonization treatment. SOLUTION: The aluminum foil composite materials are subjected to the dry distillation and carbonization treatment. This treatment is preferably executed at 250 to 700 deg.C in a continuous dry distillation furnace. If the aluminum foil composite materials include resin films, the dry distillation gases formed by the dry distillation and carbonization treatment are preferably burned and are used as the heat source for the furnace, by which the energy is effectively recycled.</p> |
