Not all plastics are the same, and they don’t all blend together well during recycling. At NIST, researchers are looking for ways to make recycled plastic stronger and more valuable. It’s all about the chemistry. Recycling plastic involves melting the material down and then molding or extracting it into new shapes. If different types of plastics are melted and mixed together, their building blocks, called polymers, may not adhere well to each other when they crystallize. That’s exactly what this
