Our kids 4 truth program has several kids that are unable to pay for their books.  It has been suggested and implemented to recycle the books.  The books that the 5 year olds and under use are the easiest to reuse.  The pages are slick and the stickers that are placed onto the pages can be removed. Also this is great for the children that forget their book or lose them.  A temporary book can be used for the night.
