can you compost receipts?
No — most receipts are thermal paper coated with BPA or BPS, chemicals you don't want in your compost or your soil.
which bins can take it?
- hot pile no
- cold pile no
- worm bin no
- bokashi no
- tumbler no
- curbside no
- curbside: Food-scrap programs exclude thermal paper for the same bisphenol reason.
why?
Thermal printers develop the image using a coating of bisphenol color developers — BPA, or BPS in 'BPA-free' stock — present at far higher concentrations than in any other consumer paper. Composting spreads those endocrine-disrupting compounds into finished compost and garden beds, and the same coating makes receipts unwelcome in paper recycling too.
watch out for
- A minority of receipts are plain uncoated bond paper, and those compost fine — see the scratch test below to tell them apart.
what to do instead
Trash them. Thermal receipts shouldn't go to paper recycling either, since bisphenol coatings contaminate the recycled fiber stream. Where stores offer email receipts, that's the cleanest opt-out.
often confused with
- Plain office paper — Regular uncoated paper composts fine — receipts are a chemistry problem, not a paper problem.
quick answers
How do I tell if a receipt is thermal paper?
Scratch it with a coin or fingernail: thermal paper shows a dark mark, because friction heat triggers the color developer. A slick, slightly shiny feel is another giveaway. Matte receipts that don't mark are plain paper and can be composted or recycled.
Are BPA-free receipts okay to compost?
Usually not. 'BPA-free' thermal paper nearly always substitutes BPS, a closely related bisphenol with similar concerns, so extension guidance treats it exactly the same: keep it out of the pile.
