can you compost books?
Yes, but only the pages — tear out uncoated pages to compost and keep bindings, glossy covers, and board out.

which bins can take it?
- hot pile yes
- cold pile caution
- worm bin caution
- bokashi no
- tumbler yes
- curbside caution
- cold pile: Loose fluffed pages only — a stack of pages mats like plywood in a slow pile.
- worm bin: Shredded pages make fair bedding in moderation; glossy stock doesn't belong.
- curbside: Whole books are usually rejected even where loose paper is accepted — recycle or donate instead.
why?
Book paper is ordinary compostable cellulose, but a bound book is a laminated brick: compressed pages wick water poorly, spines rely on hot-melt plastic glue, and covers carry coatings or cloth. Even in a hot pile, an intact paperback can surface months later with readable pages at its core.
how to prep it
- Donate or sell readable books first
- Tear out pages in bunches, then shred or crumple them
- Trash the spine, glue strip, and any glossy cover
watch out for
- Hardcover boards are often cloth- or film-laminated over dense grayboard, which resists composting and recycling alike.
- Perfect-bound spines shed hot-melt glue chips that turn up later in finished compost.
often confused with
- Magazines — Magazine pages are clay-coated gloss and don't compost; most book pages are plain uncoated stock.
quick answers
Can moldy books be composted?
Yes — mold means the paper is already digesting, and a pile finishes the job. Shred the moldy pages outdoors, skip the covers, and never put moldy books in donation bins or paper recycling.
Do old yellowed pages compost faster?
They do — yellowing is lignin oxidation and acid breakdown already underway, so brittle old pages shred easily and decompose faster than fresh bright paper.
