Building a Better Polyethylene (IMAGE)
Caption
Packaging such as juice pouches are made with bonded layers of metal such as aluminum, and different types of plastic, making them almost impossible to recycle. Because only 1-3 percent of such packaging is collected for recycling, food and beverage containers are among the top 5 items found on beaches and coastlines. To solve this problem, the University of Pittsburgh researchers propose manipulating polyethylene molecules to design layers that can each perform a specific function, creating a fully recyclable PE product.
