The answer is TRUE! Plastic bags cannot be thrown in your recycling roll cart.
We highly recommend reusing plastic bags for other uses, reducing the amount you use by opting for reusable bags instead, and if all else fails make sure to throw them in your garbage roll cart. The Material Recovery Facilities (MRFs) where your recycling is taken to be sorted cannot open anything in a plastic bag due to safety hazards. This means if there's any recyclable materials in a plastic bag then they are being put into the garbage, which is a waste of everyone's efforts.
