graveyards for unread books

I learned from this commentary that pulped books are used for road building in the UK. As more roads tend to produce more traffic, I'd prefer any remainders of my books to end up in a more environmentally friendly graveyard. Maybe as home insulation material, or as railway seats ... Even though, in an ideal world, they would all get read so much and treasured that they never would have to be pulped at all!
