At The Neat L'l Bookshop we think of used books as a serious way to Recycle/Reuse/Reread.
"Never waste a book."

Books are checked for condition and only if we cannot sell, delivered to the most appropriate charity.  Good books keep on trading.
If beyond use, we recycle properly.

Landfill is a bad word here.
