Perpetual plastic for food to go: Enabling technology

The ability to quickly identify packaging for reuse and determine its history of use will be important for enabling this new circular business model. Fluorescent labelling of packaging is an emerging technology to aid in sorting plastic waste. However, markers are currently applied as external labels. To survive multiple use and wash cycles, the fluorescent component could be blended into the polymer instead. Polymeric design reduces risk of dye leaching into food.
