Method for removing contaminants from plastic resin

Patent Bohnert, George W [Harrisonville, MO]; Hand, Thomas E [Lee's Summit, MO]; DeLaurentiis, Gary M [Jamestown, CA]

A resin recycling method that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The method includes receiving the resin in container form. The containers are then ground into resin particles. The particles are exposed to a solvent, the solvent contacting the resin particles and substantially removing contaminants on the resin particles. After separating the particles and the resin, a solvent removing agent is used to remove any residual solvent remaining on the resin particles after separation.

A resin recycling system that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The system includes receiving the resin in container form. A grinder grinds the containers into resin particles. The particles are exposed to a solvent in one or more solvent wash vessels, the solvent contacting the resin particles and substantially removing contaminants on the resin particles. A separator is used to separate the resin particles and the solvent.

Solvent cleaning system and method for removing contaminants from solvent used in resin recycling

Patent Bohnert, George W [Harrisonville, MO]; Hand, Thomas E [Lee's Summit, MO]; DeLaurentiis, Gary M [Jamestown, CA]

A two step solvent and carbon dioxide based system that produces essentially contaminant-free synthetic resin material and which further includes a solvent cleaning system for periodically removing the contaminants from the solvent so that the solvent can be reused and the contaminants can be collected and safely discarded in an environmentally safe manner.
