Plastic packaging serves important functions in modern life, and we have come to rely on it heavily. It is an exceptional product that, however, has a significant end-of-life problem. This is especially true of black plastic, which until very recently couldn’t be detected with the available technology, Near Infrared (NIR). “The emitter shines a light on the material and the sensor takes a reading of the energy that is reflected back,” says Enrico Siewert, Director of Product and Market Development at STADLER.
