can you compost coffee cup sleeves?
Yes — kraft cup sleeves are corrugated cardboard in disguise; tear them up and they belong in any pile or bin.

which bins can take it?
- hot pile yes
- cold pile yes
- worm bin yes
- bokashi no
- tumbler yes
- curbside yes
why?
A cup sleeve is single-face corrugated kraft — the same high-carbon fiber as a shipping box, up around 350:1 carbon to nitrogen, with fluting that traps air in the pile. Sleeve printing is typically water- or soy-based ink on uncoated stock, so it skips the coating problem that disqualifies glossy paper. A little dried coffee dribble just brings trace nitrogen along for the ride.
how to prep it
- Tear each sleeve into a few pieces
- Set aside any sleeve with a slick, plastic-feeling surface
watch out for
- A few specialty sleeves are coated for embossed or metallic finishes — if the surface feels slick rather than papery, trash it.
often confused with
- Paper Cups — The cup is usually plastic-lined and doesn't compost at home — the sleeve is the compostable half of your coffee order.
quick answers
Can the whole coffee cup go in with the sleeve?
Usually not — most paper cups hide a polyethylene lining that survives composting as a ghost film. The sleeve is the safe half unless the cup is certified compostable and your local program actually accepts it.
