If you’ve ever had a Capri-Sun, or other food or drink from a metallic pouch, you’re likely familiar with plastic-aluminum laminates (PAL).
PALs have long been used for toothpaste tubes and in recent years has gained popularity as pouches for food, drink and pet food. PALs are environmentally conscious over their product life-cycle because very little energy goes into their production and they are extremely light, cutting transport costs. These attributes, plus the fact they protects contents from light and air, make it attractive to manufacturers. Until now, however, they weren’t recyclable.
More than 15 years ago, materials scientists at Cambridge discovered a way to separate the aluminum contents of a PAL from their plastic ingredients using microwaves. Now, the first full-scale facility devoted to PAL recycling has opened in Luton, UK. The plant was designed, built and operated by Enval Limited, a spin-out company of Cambridge University. Gizmag has the whole story.
