Statistics from the National Press and Publication Administration show that retail sales of primary and middle school textbooks, as well as relevant teaching books, in 2018 were valued at a whopping 25.9 billion yuan ($3.9 billion). If these books could be recycled, at least 20 billion yuan ($3 billion) could be saved. Meanwhile, a lot of students complain that they must sell their used textbooks for scrap although the books initially were printed and transported at much higher costs. The fact that there is a huge waste of textbooks from primary school to university is a grim reality.
