The Food and Drug Administration (FDA) approved a new recycling process that eliminates the use of water for cleaning recycled polyethylene terephthalate (RPET) flake. ECO2 Plastics’ process combines a biosolvent that is FDA-approved for use as a food additive with liquid carbon dioxide in a closed-loop system that pours nothing down the drain. The FDA approval allows for RPET cleaned in this manner to be used in food-contact packaging.
