<p><P>PROBLEM TO BE SOLVED: To develop an apparatus for the volume-reducing of foamed materials, plastic vessels and plastic materials at a high volume reduction ratio by means of a liquid. <P>SOLUTION: The method comprises the softening and volume-reducing of a plastic by using together a volume-reduction liquid and a pressure, the volume-reduction liquid being an aliphatic dibasic acid ester and heated up to from 90°C or higher to the melting point, and the water washing of the volume-reduced plastic, and finally the recovering of the volume-reducing liquid by means of the oil/water separation. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
