When it comes to recycling, the thermoformers have gotten the process down, with most using the trim back into the extrusion of new sheet. Demand for recycled-content sheet material to meet green requirements for many packaging products continues to increase, but there are a few challenges when it comes to meeting that demand. Larry Koster of Burcham International Corp., a supplier of PET resin to the sheet industry, noted at the recent SPE Thermoforming Conference in Milwaukee, WI that “it’s hard to make any money in RPET [recycled PET], as the recovery rate for bottles is low—way below what recyclers need.” Another problem for U.S.-based PET recyclers is that about half of the PET “is exported to China” only to come back as other products.
