NOVELTY - A lamination paper is heat-boiled, ground and performed with metal and resin (MR) material removal which removes MR material by specific gravity sorting. Subsequently, cellulose in the resulting material is separated by mesh classification. Subsequently, an addition agent which blocks the generation of harmful gas, is added to separated MR material and heated, to obtain recycled paper.    USE - For recycling used paper, such as lamination paper used as containers, such as beverage and foodstuffs.    ADVANTAGE - The paper resources are recycled efficiently and easily without refuse generation. The cellulose which is used as paper of fine quality is conventionally separated and taken out from the lamination paper currently treated as refuse. The recycling processing method of used paper produces gel fuel as the remaining product.    DETAILED DESCRIPTION - A lamination paper used as containers, such as beverage and foodstuffs, is heat-boiled by heating-boiling process (1) and left for fixed time in an acidic solution or acidic water. The heat-boiled paper is ground using a mixer by grinding process (8). The ground material is performed with a metal and resin material removal process (11) which removes a metal or resin material by specific gravity sorting. Subsequently, the resulting material is performed with a cellulose separation process (15) which separates a cellulose from the solution which is free from metal and resin material, by mesh classification. Subsequently, an addition agent which blocks the generation of harmful gas, such as calcium hydroxide and sodium hydroxide, is added to the separated metal and resin material and heated, to obtain recycled paper.
