New device and method detect percentage of recycled plastic in plastic products

Recycled plastics are promoted on everything from water bottles and fleece jackets to shopping bags and yogurt cups: "This product is made with XX% recycled plastic." Verifying such claims, however, is another matter because there is no quick and reliable way to measure how much recycled plastic these products contain. University at Buffalo researchers are addressing this problem by combining several scientific tests, as well as artificial intelligence, to create a new method for differentiating recycled plastic from new plastic.
