Welcome to the forum. I don't worry about plastics, either they go with the steel shred as fluff or they get put in with my curbside recycling. I took plastics in to a buyer about 6 years ago and I took in about 1500 lbs and had to truck it about 50 miles through city, stop and go driving, and got a whole hundred bucks for my hassles. now they go as fluff or curbside.
