can you compost pizza boxes?
Yes, but tear off and trash any sections soaked stiff with grease — the rest composts beautifully.

which bins can take it?
- hot pile yes
- cold pile caution
- worm bin caution
- bokashi no
- tumbler yes
- curbside yes
- cold pile: Slow piles break grease down lazily — bury pieces deep so they don't attract pests.
- worm bin: Clean sections make good bedding; keep grease-soaked parts out.
why?
Corrugated cardboard is a high-carbon brown, and the smear of cheese grease that ruins a box for paper recycling is actually food for compost microbes. The limit is saturation: grease-stiffened cardboard sheds water, mats into airless layers, and draws pests in slow piles.
how to prep it
- Shake out crusts, cheese, and any liners
- Tear the box into palm-sized pieces
- Trash sections that are stiff or translucent with grease
watch out for
- Sections soaked through with grease are the part recyclers still reject — those pieces belong in the compost or the trash, not the paper bin.
- Glossy or heavily printed boxes from some chains shed coatings; plain kraft boxes are the safe bet.
often confused with
- Clean Cardboard — Clean cardboard should go to recycling first — composting is the fallback for soiled boxes.
quick answers
Can pizza boxes go in the recycling bin instead?
Usually yes now. Mill testing published by the paper industry in 2020 found that the grease and cheese on a typical delivery box does not hurt the recycling process, and most US programs accept boxes as a result. Check your city's list, pull out the liner and plastic tripod, and send the sodden pieces to the pile instead.
Do I need to remove the little plastic table?
Yes — the 'pizza saver' tripod is plastic, and any wax-paper liner should go in the trash too unless it's certified compostable.
