Imagine the massive inconvenience of separating your plastics so that your recycling facility can actually recycle more plastic waste instead of if ending up in a landfill 🤦
It's not that the plastic isn't recyclable it's that you cant mix plastics and recycle them. So if there is a doubt at all what a plastic is then it's thrown away or if it can't be separated from other materials or contaminated with oil or something.
