Key Discussion Points and Insights

1. The Passion of Pizza Box Collecting

• Scott Wiener recounts the origin of his obsession:

  "I noticed that pizzeria had boxes on the wall. It was this yellow, bright yellow with orange stripes. Crazy pizza box. Growing up in suburban New Jersey, all pizza boxes were flimsy white, smudgy red ink...this was a yellow box. It just, it didn't seem legal." —Scott Wiener (01:00)

• Wiener now owns over 1,800 pizza boxes from every continent, even Antarctica:

  "Apparently they have a commissary that has a pizza station. They sent me one with maybe 30 or 40 signatures of scientists working at the McMurdo Station." —Scott Wiener (01:53)

2. A Brief History of Pizza Box Evolution

• Early Days:
  • Pizzas originally transported in copper “stufas” in Naples.
  • Evolved into paper bags and then pastry-style boxes as pizza became a mainstream, shareable American food post–WWII.

    "As pizza got more popular and it became more of a party food, really around the middle of the 20th century, that's when we switched to the box, which at first was like a pastry box..." —Scott Wiener (03:23)

• The Domino’s Revolution:
  • Founder Tom Monahan (Domino’s) needed stackable, heat-retaining boxes for high-volume delivery.
  • In 1960s, Domino’s patented the corrugated “Michigan style” box with flaps and “ears”—a durable and heat-retentive industry standard.

    "His whole idea was, I need something that could stack really neatly, that's gonna hold onto the heat, and it's not gonna cost so much." —Scott Wiener (04:17)

3. Manufacturing & Market Scale

• Industry Powerhouses:

  • Most pizza boxes come from a few large packaging companies, with WestRock as a major player.
  • The pizza box sector represents ~1.7% of all corrugated cardboard volume—about 3 billion boxes yearly in the US.

    "When you do the math, about 1.7% of the corrugated volume is pizza boxes. So there's about 3 billion pizza boxes a year that the US market consumes." —Patrick Kivitz (05:31)

• Supply Chain Control:

  • WestRock controls the process from forest to finished product—including custom design and mass production.

    "We have our own forestry, we have mills in our system...eventually cut, printed, and they arrive at our customer sites cleanly." —Patrick Kivitz (05:58)

• Design Aesthetics:

  • Many generic boxes use clip-art designs:

    "The typical pizza box is a clipart box and that's, you know, the image of the chef, the image of the pizza that's steaming..." —Scott Wiener (06:36)

4. Engineering the Perfect Pizza Box

• Materials and Design:

  • Corrugated cardboard: outer/inner liner and fluted middle (for heat retention and strength).
  • Key design requirements:
    • Heat retention
    • Moisture resistance
    • Stackability and transport efficiency
    • Easy assembly for pizzeria employees

    "The trends...are really about how do you make them easier to set up so that the large pizza brands can reduce labor..." —Patrick Kivitz (07:46)

• Box-Folding Speed:

  • At events like the International Pizza Expo, there are competitions for the fastest box folder.
  • Domino’s boxes are especially optimized:

    "The standard corrugated take me about 7 or 8 seconds, but the Domino's box is about 5 seconds." —Scott Wiener (08:35)

  • Domino’s delivers 1.5M pizzas daily; time savings add up to 1,200+ labor hours per day.

5. Flaws and New Inventions

• Flavor & Texture Issues:

  • Steam is trapped inside, often affecting pizza quality:

    "The problem with pizza is that it's a baked product...but it's also a high humidity product...bread and humidity are enemies. The box is not good for the pizza." —Scott Wiener (10:55)

  • Cardboard breakdown can leave an undesirable aftertaste.

• Creative Engineering Attempts:

  • Innovations include boxes that transform into storage containers, tables, or slicing tools.
  • Apple’s clamshell compressed-fiber box gets a mention.
  • Standout: A Mumbai design that channels steam away for optimal texture:

    "It's an amazing box that plays with the corrugated structure...adds ventilation that creates these channels within the fluted medium, which allows steam to escape indirectly." —Scott Wiener (12:09)

• Cost as a Limiting Factor:

  • Most pizzerias won't pay more for marginal improvements.

    "As soon as costs go up by 2 cents, nobody will use it. They don't make economic sense." —Scott Wiener (12:55)

6. Afterlife of the Pizza Box: Recycling Realities

• Campus Case Study:
  • Pizza boxes among top waste streams at colleges.

    "We would see, you know, 20 or 30 pizza boxes for a dorm room party, or three or 400 for a back to school event." —Eric Nelson (13:33)

• Sorting Misconceptions:
  • Contrary to popular belief, pizza boxes are usually recyclable (up to 7 times—even with some grease).
  • Boxes are baled and sold on the open market as OCC (“old corrugated cardboard”); current low prices benefit box manufacturers.
• The Recycling Loop:

  "They have a recipe basically where they'll add the mixed paper bale. They might add some virgin pulp...and then it's turned into a slurry and pressed into paper." —Eric Nelson (15:04)

7. Obsessions and Ironies

• Wiener, despite being the world’s most passionate pizza box collector, never actually eats pizza out of a box:

  "No pizza will ever taste as good coming out of the box than it did going in into the box." —Scott Wiener (15:25)

Notable Quotes & Memorable Moments

• On discovery:

  "Anything that's taken for granted, you know, there's more depth to it. And with pizza boxes, once you scratch that surface, you realize, oh, there's so much more going on here." —Scott Wiener (02:38)

• On clipart and design repetition:

  "You still find that on most generic pizza boxes." —Scott Wiener (06:55)

• On innovation resistance:

  "You know, normal humans just think, oh, the box that works better should be the one that we all use. And as soon as costs go up by 2 cents, nobody will use it." —Scott Wiener (12:55)

[McDonald's Advertiser]

Quick, choose a meal deal with McValue. The five dollar McChicken meal deal, the six dollars McDouble meal deal, or the new seven dollar Daily Double meal deal. Each with its own small fries, drink and four piece of McNuggets. There's actually no rush. I'm just excited for McDonald's for a limited time only.

Not valver McDelivery a KFC tale in the pursuit of flavor. The greatest insult the Colonel ever suffered was being served a wrap that was just a snack by a friend. So he took two crispy tenders, lettuce, tomatoes and pepper mayo and wrapped them in a soft tortilla. It wasn't a snack, it was a meal. Called it a twister and never called that friend again. The Colonel lived so we could chicken the twister. Now back at KFC Classic or with bacon. Also try it spicy. It's finger licking good.

[Narrator (Zachary Crockett)]

Back in 2008, Scott Weiner was on a trip to Israel and had a curious awakening in a restaurant.

[Scott Wiener]

I noticed that pizzeria had boxes on the wall. It was this yellow, bright yellow with orange stripes. Crazy pizza box. Growing up in suburban New Jersey, all pizza boxes were flimsy white, smudgy red ink. And you know, this was a yellow box. It just, it didn't seem legal. It just, it stuck with me. And from then on, anytime I saw a box that looked different from the ones I grew up with, I would save them.

[Narrator (Zachary Crockett)]

Pizza boxes became Scott Wieners obsession. He now holds the Guinness World record for the world's largest collection of them. More than 1,800 in total. Pizzerias from all over the world have sent him their packaging.

[Scott Wiener]

I have every continent. I have a box from Antarctica.

[Narrator (Zachary Crockett)]

Who makes pizza in Antarctica?

[Scott Wiener]

Apparently they have a commissary that has a pizza station. They sent me one with maybe 30 or 40 signatures of scientists working at the McMurdo Station.

[Narrator (Zachary Crockett)]

Wieners collection is a tribute to an everyday item that is often underappreciated by pizza enjoyers across the country, which is almost all of us. Americans consume billions of pizzas every year, around £23 worth per person. The majority of those pizzas are ordered for delivery or to go. And the boxes the pizzas are transported in have to be carefully engineered to uphold the integrity of the pies inside.

[Scott Wiener]

Anything that's taken for granted, you know, there's more depth to it. And with pizza boxes, once you scratch that surface, you realize, oh, there's so much more going on here.

[Narrator (Zachary Crockett)]

For The Freakonomics Radio Network. This is the economics of everyday things. I'm Zachary Crockett. Today, pizza boxes. The pizza box is a relatively modern invention. In Naples, where pizza was invented, bakers used to transport their products in copper containers called stufas. Eventually they were replaced by paper bags laid out horizontally. After World War II, the US experienced a pizza awakening. Scott Wiener knows a lot about this history.

[Scott Wiener]

As pizza got more popular and it became more of a party food, really around the middle of the 20th century, that's when we switched to the box, which at first was like a pastry box, like if you get a pound of cookies, it's that type of box. Between southern Italy and the United States, pizzas shifted, became larger, became more of a sharing food. And if you have 16 inch boxes that are flimsy, a stack of those, it doesn't make sense.

[Narrator (Zachary Crockett)]

When modern pizza delivery really took off in the 1960s, those flimsy boxes became a big problem for high volume transportation. So a fellow named Tom Monahan, founder of then regional pizza chain Domino's, decided to do something about it.

[Scott Wiener]

His whole idea was, I need something that could stack really neatly, that's gonna hold onto the heat, and it's not gonna cost so much.

[Narrator (Zachary Crockett)]

Domino's worked with a manufacturer in Detroit. The solution they came up with was a box made out of corrugated cardboard, which is a much sturdier material.

[Scott Wiener]

There's an outer liner, an inner liner, and then in between the two, there's a fluted piece of paper, which is what gives it its thickness and it's what allows heat retention and it gives it strength.

[Narrator (Zachary Crockett)]

The box was called the Michigan style. It has a front flap that folds over with little side ears that tuck into the cracks and keep the box shut. 60 years later, this is more or less the same box design most pizza companies still use today. When you go to a pizza shop, the odds are pretty good that they buy their boxes from a packaging conglomerate. A few big players control the pizza box market, including West Rock, based in Sandy Springs, Georgia. Patrick Kivitz runs the company's corrugated division.

[Patrick Kivitz]

We make essentially every corrugated box that you're familiar with. You know, from an E Commerce box to anything that you can sell.

[Narrator (Zachary Crockett)]

Kivitz says that pizza boxes are a major part of the business.

[Patrick Kivitz]

When you do the math, about 1.7% of the corrugated volume is pizza boxes. So there's about 3 billion pizza boxes a year that the US market consumes.

[Narrator (Zachary Crockett)]

WestRock is one of the largest pizza box manufacturers in America. They sell to pretty much everyone from Domino's to mom and pop neighborhood joints. The company controls the entire pizza box supply chain.

[Patrick Kivitz]

So we have our own forestry, we have mills in our system where we start producing the paper, our corrugated converting plants, where we start making the corrugated materials, that's then eventually cut printed and they arrive at our customer sites cleanly.

[Narrator (Zachary Crockett)]

Westrock has a team of graphic designers who make custom artwork for clients boxes. They also sell boxes with generic artwork to restaurants that don't care as much about branding or can't afford custom art. Scott Wiener says that if you look closely enough, you'll see the same designs pop up at different pizzerias.

[Scott Wiener]

The typical pizza box is a clipart box and that's, you know, the image of the chef, the image of the pizza that's steaming. Maybe there's a border of typical pizza ingredients around the edge of the box like the boot of Italy, that kind of stuff. You still find that on most generic pizza boxes.

[Narrator (Zachary Crockett)]

Westrock also employs engineers who work on the functionality of boxes.

[Patrick Kivitz]

The pizza companies want the pizza to arrive at their consumers houses at the right temperature. So heat, reservations, moisture resistance, ventilation, making sure that there's nothing too much condensation on the inside of the lid, the height of the box, the integrity of the box are important because, you know, transportation sustainability. We have as many boxes in a delivery vehicle as possible so that, you know, we reduce the delivery costs. So it's not as trivial as you may think.

[Narrator (Zachary Crockett)]

Another key consideration in the design process is to make sure boxes are easy to set up. They're sold to pizza chains flat and have to be assembled by the pizzeria's employees. Every second of that labor counts.

[Patrick Kivitz]

The trends that we've seen over recent years is really about how do you make them easier to set up so that the large pizza brands can reduce labor when you fold them to the final pizza box configuration. It's important that that goes as fast and effective as possible.

[Narrator (Zachary Crockett)]

At the International Pizza Expo, an industry convention in Las Vegas, Westrock hosts a competition to find the world's fastest pizza box folder. Perhaps nobody takes pizza box agility more seriously than Domino's. The chain has made it a central part of their identity in commercials and advertisements. Domino's fastest pizza box folder. Domino's has its own patented box which is designed to be assembled in a few seconds. Wiener has firsthand experience with it.

[Scott Wiener]

A few years ago, I got a job at a Domino's essentially for research. And part of my job every day when I showed up was fold pizza boxes and those flimsy boxes take about 20 seconds 25 seconds to fold. The standard corrugated take me about 7 or 8 seconds, but the Domino's box is about 5 seconds.

[Narrator (Zachary Crockett)]

Domino's delivers 1.5 million pizzas every day, so saving 3 seconds per box adds up to more than 1200 hours of labor. That's great for business, but when it comes to improving the consumer's experience, pizza boxes still have a ways to go

[Narrator (Zachary Crockett)]

when he's not collecting pizza boxes Scott Weiner runs Scott's Pizza Tours in New York City. He eats pizza on a weekly basis and he's found that even the best boxes on the market are flawed.

[Scott Wiener]

The problem with pizza is that it's a baked product, it's a bread, but it's also a high humidity product with tomato and cheese and whatever topping you have. So you know bread and humidity are enemies. The box is not good for the pizza. It traps in steam. Sometimes you do get some breakdown of the paper and then you you taste a little cardboard aftertaste.

[Narrator (Zachary Crockett)]

In recent years there have been numerous efforts to re engineer the pizza box from the ground Up.

[Scott Wiener]

Somebody has made a version of it that breaks down into a storage container for your leftover pizza plus plates. Then there's a version of it that turns into its own table where the lid flips over and it becomes a stand. Then there's the one that's got the built in spatula that has a perforated edge so you can use it to cut up the pizza a little bit smaller. It's totally bonkers.

[Narrator (Zachary Crockett)]

A number of inventors have patented round pizza boxes. Even the technology giant Apple took a stab at one for use in its corporate cafeterias. It's shaped like a clamshell and it's made out of compressed fiber. But the best pizza box design that Wiener ever saw came out of Mumbai, India.

[Scott Wiener]

It's an amazing box that plays with the corrugated structure. It also adds ventilation that creates these channels within the fluted medium, which allows steam to escape indirectly. So this way steam gets out, the relative humidity inside the box lowers without it being open with, you know, 25 different vent holes. It's really brilliant. It's beautiful.

[Narrator (Zachary Crockett)]

These boxes are all better in some way than the existing models on the market. But it's unlikely that any of them will disrupt the status quo. Small to medium sized shops spend around 30 cents per box. The big guys order higher volumes and spend much less. Keeping expenses low is more important than marginally improving the pizza experience.

[Scott Wiener]

You know, normal humans just think, oh, the box that works better should be the one that we all use. And as soon as costs go up by 2 cents, nobody will use it. They don't make economic sense.

[Narrator (Zachary Crockett)]

Probably the most important part of the pizza box supply chain is what happens to boxes after a pizza is consumed. Eric Nelson has been in the recycling and compost business for more than a decade. He spent seven years working in the waste reduction program at the University of Kansas. And the pizza box was among his chief concerns.

[Eric Nelson]

We would see, you know, 20 or 30 pizza boxes for a dorm room party, or three or 400 for a back to school event.

[Narrator (Zachary Crockett)]

Just constant stream of pizza coming in.

[Eric Nelson]

Yeah, was definitely one of our larger waste streams on campus.

[Narrator (Zachary Crockett)]

When he was on campus, Nelson says he saw all kinds of stuff inside of pizza boxes.

[Eric Nelson]

Anything from cheese stuck to the pizza box to a lot of times the parmesan and red pepper packets were in there. We saw a lot of pepperoncinis, a lot of marinara.

[Narrator (Zachary Crockett)]

These tarnished boxes rarely ended up in the recycling bin.

[Eric Nelson]

Historically, the messaging was that a pizza box is too greasy and dirty to recycle. So you need to Throw it away.

[Narrator (Zachary Crockett)]

In reality, that's a myth. In most municipalities, the cardboard pizza boxes are made out of can be recycled up to seven times grease. And all the boxes that do get recycled are broken down and tied up into giant bales that weigh more than £1,000. Those get sold on the spot market as a commodity, just like oil or wheat under the name OCC or old corrugated cardboard. Recently, the going rate for this old cardboard has fallen as low as $30 a ton, down from well over 100 in previous years. That's good news for pizza box manufacturers like Westrock, who buy it and turn it into new boxes.

[Eric Nelson]

So this is bought by paper mills and they have a recipe basically where they'll add the mixed paper bale. They might add some virgin pulpit, and then it's turned into a slurry and pressed into paper.

[Narrator (Zachary Crockett)]

For Eric Nelson, the pizza box is a part of a beautiful cycle. But Scott Weiner has a different take.

[Scott Wiener]

I mean, the irony of my life is that I collect pizza boxes. I have 1,800 of them in a storage unit that I pay for. I'm obsessed with them. But I do not eat pizza out of pizza boxes. No pizza will ever taste as good coming out of the box than it did going in into the box.
