Shalom:
Many non-religious Jews do not know the prohibition on throwing away books or other written materials that contain the name of G-d.
There are many books on various aspects of Judaism that continue to be written and read by Jews and non-Jews alike that contain G-d’s name that I imagine are discarded after having been read..! May I offer a suggestion…That Rabbis around the World contact publishers of Jewish books and ask them to include a sentence similar to this one: “Please do not throw away this book after reading it as it contains the name of G-d”. This request, coming from Rabbis would no doubt carry much weight. Thank you for your consideration.
