can you compost glossy paper?
No — recycle glossy paper instead; some coatings are harmless clay, others are plastic, and you can't tell by looking.
which bins can take it?
- hot pile no
- cold pile no
- worm bin no
- bokashi no
- tumbler no
- curbside caution
- curbside: Programs that accept all paper will take it, but recycling is the better stream for clean glossy sheets.
why?
The shine on coated paper comes from either a kaolin-clay layer polished smooth — inert and technically compostable — or a plastic or UV-cured varnish that sheds film fragments into finished compost. The two are indistinguishable without testing, so extension guidance defaults to keeping glossy stock out of home piles. Recycling mills, on the other hand, de-ink and separate coated paper routinely, making that the clean answer.
what to do instead
Put glossy paper in curbside recycling — mills handle clay coatings and inks as a matter of routine. Reserve the compost question for food-soiled coated paper, and even then only if your municipal program explicitly accepts all paper.
quick answers
How can I tell clay coating from plastic coating?
Tear the sheet: clay-coated paper tears cleanly like normal paper, while plastic-coated stock stretches slightly or shows a filmy layer at the tear. Scratching helps too — clay scrapes off as white dust. Some composters accept sheets that pass both tests; the cautious call is still recycling.
