UpSolv Receives FDA Clearance for Food-Grade Recycled Polystyrene

UpSolv (formerly Polystyvert) announces that it has received a No Objection Letter (NOL) from the U.S. Food and Drug Administration (FDA), confirming that its proprietary secondary recycling process can produce recycled polystyrene (rPS) suitable for direct food-contact applications, including yogurt cups and other packaging formats.

UpSolv’s technology was validated through an initial collaborative project that produced yogurt cups made entirely from polystyrene waste. These cups featured a monolayer structure with 100% recycled content in direct contact with food—successfully passing stringent challenge and migration tests without the need for an ABA (virgin-recycled-virgin) structure. This innovation offers a true drop-in solution for manufacturers.

The FDA’s No Objection Letter confirms that packaging made with UpSolv’s recycled resin meets the highest standards for food safety, material quality, and performance.

One of the key differentiators of UpSolv’s patented dissolution and purification process is its ability to selectively remove a wide range of contaminants—including solid residues such as labels and mixed plastics, as well as soluble substances like colorants, dyes, odors, and fillers—while preserving the functional additives required for high-performance applications.
