Abstract

A method of making containers from resin recycled in a solvent wash followed by carbon dioxide bath that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The method includes receiving resin particles contaminated with contaminants and then exposing the resin particles to a solvent, which substantially removes the contaminants. The resin particles and the solvent are separated after the contaminants are substantially removed. The resin particles are next exposed to a solvent removing agent, which removes any residual solvent or trace contaminants remaining on the resin particles after separation. After exposure to the solvent removing agent, the resulting resin particles are substantially contaminant and solvent free. In various embodiments, the containers are fabricated from the recycled resin in either stretch molding machines or are first shaped into pre-forms, placed into a mold, and then the pre-forms are heated and air-blown, to assume the shape of the mold. The types of containers that can be fabricated from the above method include but are not limited to soda and soft drink bottles, soap and shampoo bottles, cleaning supply bottles, food and condiment containers, oil containers, pesticide containers, product packaging containers, or any other container made from resin.
