Julie Brooks-Girskiene I remember reading a big story about how people are putting them in the plastic recycling bins and then they contaminate the whole batch of recycled plastic and it becomes useless.
I've read about that as well, and I think it has become quite a bit problem. Unless you have someone actually physically looking at each bag before it goes into the recycling machines, which is of course completely impractical then this is a potential issue.
People really need to learn to pay attention to what they put in which bins, which would solve that problem.
Maybe there is some other solution for this that I don't know about though.
