Actually, I think the waste plastic you are referring to is sold to an incinerator if one is near buy. Plastic has good heat value due to the petrochemicals used to make them. They probably do make some money off these sales, but it is probably not much. I take my class to the local recycling center every year, and the man that runs it is never excited about dealing with this type of plastic. That what happens here anyway...different state, different rules I suppose.
