Im sure it just gets passed down the line. Not a big deal. If it was, yards would be checking every fridge, dryer, microwave for non metal items stuffed in them. I have had yards tell me that they cant take dishwashers as it had too much plastic, but they take a fridge! Been told bikes need to have the tires off of them but go back and see bikes with tires on them. I try to remove most anything that is non metal that I can do without much trouble, if it is a pain in the a$$s then in it goes as is!
