ABSTRACT:
A recycled plastic material is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing the dried thermoplastic solid matter other than the thermoplastic.
