We could advice them to tear away the blank pages and make a rough book for the future use. The other filled books could be recycled. Some textbooks can be given to younger kids of the school so that they can use them second-hand. some books can be donated to poor kids who can use the books for reading or are atleast useful to them. Many students can also preserve the books after their final exams.
