Are Pizza Boxes Recyclable? What to Do With Greasy Boxes
By the Avco Boxes team · Updated
Pizza boxes are usually made of corrugated cardboard, which is widely recyclable. The problem is grease and leftover food, which can make paper harder to recycle. Rules differ by local program, so check your city or hauler. Common advice is to remove food scraps, tear off heavily soiled parts, and recycle the clean lid where accepted.
Why grease is the sticking point
Most pizza boxes are corrugated cardboard: a fluted paper layer glued between flat paper liners. Clean corrugated cardboard is one of the most commonly collected materials in curbside and drop-off recycling, so the box itself is not the problem.
The problem is what the pizza leaves behind. Paper is recycled by mixing it with water and breaking it back down into fibers. Oil does not mix with water, and cheese, sauce and crusts are not paper at all. When a lot of food-soiled cardboard ends up in a batch, it can lower the quality of the recycled fiber. That is why recycling programs treat a greasy box differently from a clean shipping carton, and why their answers are not all the same.
The rules depend on where you live
There is no single national rule for pizza boxes. Each city, county or hauler decides what its own recycling and compost programs accept, based on the facilities it uses. In practice, you will find a few different approaches:
- Programs that accept pizza boxes with light grease spots, as long as food is removed.
- Programs that ask you to tear off greasy or food-covered sections and recycle only the clean parts.
- Programs that send food-soiled cardboard to a curbside compost or organics bin instead.
- Programs that ask for soiled cardboard to go in the trash.
The quickest way to know is to look up your city or hauler's recycling guide and search for "pizza box". Many list it by name because it is such a common question. If yours does not, a call or email to the hauler will settle it.
How to get a pizza box ready for the bin
If your local program does not say otherwise, this is the general advice most people follow:
- Empty the box. Crusts, cheese and any leftover food go in compost or trash, not recycling.
- Take out anything that is not cardboard: liners, paper sheets, dip cups, napkins and the small plastic stand that keeps the lid off the cheese.
- Look at the bottom. If it is heavily stained or has food stuck to it, tear off those parts.
- Put the clean lid and any clean sides in recycling, if your program accepts them.
- Put the soiled parts in compost where food-soiled paper is accepted, or in the trash where it is not.
- Flatten what is left so it takes less space in the bin.
| Part | Typical destination | Worth checking |
|---|---|---|
| Clean lid and sides | Recycling | Whether your program takes pizza boxes |
| Greasy or food-covered bottom | Compost where food-soiled paper is accepted; otherwise trash | Whether lightly greasy boxes are accepted as-is |
| Leftover food | Compost or trash | Whether your area has food-scrap collection |
| Paper liner or sheet | Compost where accepted; otherwise trash | How your program treats food-soiled paper |
| Plastic lid stand, dip cups | Depends on the program | Whether small plastic items are accepted |
Are pizza boxes compostable?
Cardboard is made from plant fiber, so it can break down in compost, and food-soiled paper is the part of the box that many people send to compost rather than recycling. Whether that works for you depends on what is available.
Some cities and haulers run curbside organics collection that accepts food-soiled paper and cardboard; others do not accept paper at all, so check the list. In a backyard pile, cardboard is commonly added as a dry, carbon-rich material. Tearing it into small pieces helps it break down faster. Home composters often keep large amounts of cheese, meat and oil out of the pile because they can attract pests and slow things down, so scrape off the food first.
For pizzeria owners: what to tell customers
Customers ask this question about your box, so it helps to give them a simple, honest answer. A short disposal note printed on the box can do that. Keep it general and accurate, because your customers may live under different recycling programs. For example:
"Done with your pizza? Remove leftover food, tear off greasy parts and recycle the clean cardboard where your local program accepts it."
- Put the note somewhere it will be read, such as a side panel or the inside of the lid. Our pizza box design guide covers where text prints cleanly on corrugated board.
- Avoid absolute promises such as "100% recyclable everywhere". Point people to their local rules instead.
- Only mention certifications or test results your packaging actually carries.
- If you use a liner or a lid stand, the note can remind customers to take it out before the box goes in recycling.
Avco's custom pizza boxes are corrugated, made in the USA in 14 sizes, with a white or kraft exterior and a kraft interior. A disposal note can go into your artwork like any other text, and you see exactly how it reads on the free digital proof before anything is printed. Setup is a one-time $75. If you line your boxes, the Krispy Crust pizza liner drops into the box and sits under the pie.
Frequently asked questions
- Can you recycle a greasy pizza box?
- It depends on your local program. Some accept boxes with light grease once the food is removed; others ask you to tear off greasy parts and recycle only the clean cardboard. Check your city or hauler's recycling guide.
- Are pizza boxes compostable?
- Cardboard is plant fiber and can break down in compost. Many people compost the food-soiled parts of a pizza box where a curbside organics program accepts food-soiled paper, or tear it into pieces for a backyard pile after scraping off the food.
- What if I can't find my local rules?
- Contact your hauler or your city's waste department and ask about pizza boxes specifically. Food-covered cardboard can cause problems in a recycling batch, so if a box is heavily soiled and you can't confirm the rules, recycling only the clean lid is a cautious approach.
- Should I remove the paper liner before recycling?
- Yes. Take out liners, paper sheets, dip cups and the plastic lid stand before the box goes in recycling. Where each of those goes depends on your local program.
