In my experience, if you can get a car to the scrapyard yourself, they will pay for it, but if they collect it they may charge you. I got 50 drinking vouchers for our old Escort that only just made it to the yard.
They would probably charge more to collect the remains after all the good bits have been stripped, 'cos they can't sell those bits themselves.
Or you could put the whole thing up on fleabay, buyer collects...
