What happens if a customer's recycling bin is overly contaminated?

Some recycling companies will pick up overly contaminated recycling. However, the recyclables will eventually be thrown in the garbage either on the spot or at the recycling center. If someone doesn't rinse a bottle that is fine, but if there are materials in the bins that are on the list that can’t be recycled, including full jars of food or too many plastic bottle lids, they will end up as trash. Thus, none of those items will actually be recycled.
