7 doors cut in half (BL7)

We recently had our doors changed and the workmen left the doors in the garage,, but said they had cut them in half so so we could carry them better. We wanted to get the waste disposal people to pick them up and they said they can’t do. So if anyone has any ideas what they can use them. could do with them - Please contact me as soon as possible. Would they be suitable for bonfire night??
