Great question! As a general guide, if it came from the earth it can be composted. That said, it can be tricky to know if some packaging is compostable. Commonly it will say “compostable” on it, which we are glad to accept. If it is something a little less usual, you may find it listed on our Compost Guide. If you are still unsure, contact us with your inquiry; and if you can, please provide a photo so we can have a look. We love finding more things to compost!
