<p>PURPOSE: To separate and recycle a fiber mixture by supplying the fiber mixture containing cellulosic fiber and the fiber composed of synthetic polymer and subjecting the mixture to a microbial hydrolysis in which the cellulosic fiber is completely degraded. CONSTITUTION: The material having the fiber mixture containing the cellulosic fiber is recycled. At this time, at first, in the first stage, the fiber mixture containing the cellulosic fiber and the fiber composed of the synthetic polymer is supplied. Then, in the second stage, the mixture is subjected to the microbial hydrolysis in which the cellulosic fiber is completely degraded. After the second stage, microbe and hydrolyzate may be removed or remaining synthetic polymer may be recovered and recycled. Moreover, the hydrolyzate may be anaerobically fermented to be converted to biogas. In this way, the fiber mixture containing the cellulosic fiber and the fiber composed of the synthetic polymer is separated and recycled.</p> |
