One man's garbage is another man's treasure. While the concept is as old as the hills, it's taken on a new, greener meaning this decade. And it even has a new name: upcycling. "Upcycling is finding value in the material as it exists now, retaining that value or increasing it by turning it into a new creation," explained Stacey Cusack, 26, public relations manager for a company born from the upcycle theory called Terracycle, Inc. based in Trenton, N.J. The term "upcycle" is attributed to William McDonough, one of the co-authors of the book "Cradle to Cradle," published in 2002. "Our founder, Tom Szaky considers (McDonough) his mentor," Cusack said. Szaky, according to Cusack, dropped out of Princeton University almost 10 years ago at age 19 to start what would become Terracycle, a global upcycling company that converts trash (snack bags, cookie wrappers, and drink pouches) into a variety of products, such as Frito Lay messenger bags, Skittle kites and Capri Sun totes.
