ABSTRACT:
A process for reclaiming plastic containers includes the steps of providing containers having an adhesive composition affixed thereto, sorting the containers, and internally pressurizing the containers. The steps also include adding heated liquid into the containers for liquefying residue within the containers and for loosening an adhesive composition affixed to the containers. The steps further include allowing the containers to depressurize, removing the liquid from the containers, and granulating the containers thereby forming granular masses.
