<p><P>PROBLEM TO BE SOLVED: To provide a recycle information management system for a polystyrene product capable of recycling a volume-reduction solvent and surely collecting styrene foam at a low cost. <P>SOLUTION: This information system is provided with a solvent supply data storage means storing a supply quantity of the volume-reduction solvent, a gel drawing data storage means storing data about a drawing quantity of gel type polystyrene reduced in volume by means of the volume-reduction solvent, a regenerated solvent drawing data storage means storing data about a drawing quantity of a reproduced volume-reduction solvent, and a regenerated polystyrene data storage means storing data about a production quantity of regenerated polystyrene separated from the gel polystyrene. This system manages distribution between traders handling the volume-reduction solvent, the gel polystyrene reduced in volume by means of the volume-reduction solvent, the regenerated polystyrene separated from the gel polystyrene, and the volume-reduction solvent. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
