And. Black plastics are separated from others early in most recycling processes. Black pigments can make it difficult for NIR sensors to discern, for example, polypropylene from polyethylene, which makes for a lower quality pellet mix in the end. Or at worst, makes it so low quality that it becomes incinerator fuel.
