The saying goes, one man's trash is another man's treasure. For TerraCycle, an upcycling and recycling company in Trenton, N.J., trash from schools in Knoxville and surrounding areas has become its treasure. Items that are traditionally non-recyclable — such as Frito-Lay chip bags, Capri Sun drink pouches, MOM Brands cereal bags and Colgate oral care products — are collected to make products sold in stores such as Target. The company recycles — or upcycles — trash into backpacks, tote bags, pencil cases, notebooks, messenger bags, and binders as well as watering cans and plant caddies.
