摘要

Method for recovering fibrous materials and/or laminates from paper whether is is laminated or not. The paper is fiberised by introducing it into a watery suspension comprising those micro-organisms of the type that grow on the constituents of the paper such as starch and cellulose, or which grow in chemicals such as carboxylic acid, flotation media and inks. Preferably, water used in the paper manufacturing process should be used as the watery suspension preferably having a pH and temperature of between 4 and 7 and 40 DEG C respectively.
