<p><P>PROBLEM TO BE SOLVED: To provide a system for easily recycling increasing recyclable waste like waste plastic by effectively utilizing it or reducing the amount of incineration or land reclaiming at a low cost. <P>SOLUTION: One reason of poor recycling ratio of the waste plastic is that much of the waste plastic is incinerated or used for land reclaiming since food residues or contaminants adhered to the plastic prohibit recycling. By completely washing the contaminants adhered to the waste plastic, the recycling ratio can be increased. The waste plastic is subjected to measurement during movement on a belt conveyor equipped with a volume measuring instrument and charged into a washer body. The charged waste plastic is washed by rotation of a washing tub. The waste plastic after washing is moved to a dehydrating system together with washing water by forward tilting of the washing tub, and dehydrated. The dehydrated waste plastic is recovered into a container box, and the washing water entering a water collection cylinder at an outer part of the dehydrating system is filtered by a filtering device and returned to the washing tub. This repeated operation yields little amount of discharge of washing water and causes no environmental pollution. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
