I sell compostable packaging, so I’m about to argue against buying it in some situations. Read the rest with that in mind. I’ve spent sixteen years watching operators make the switch with good intentions and no plan, and I’d rather lose the order than watch a certified compostable clamshell ride a garbage truck to a landfill.
Here is the thing nobody puts on the label: “compostable” describes what a product can do under specific conditions, in a specific kind of facility, after a specific chain of decisions by people who never see your menu. It’s a product capability that depends entirely on disposal conditions, not a fixed property of the container. If you don’t join that system, you didn’t buy compostable packaging. You bought a more expensive way to fill a trash can.
The access map, honestly
The best national data comes from the Sustainable Packaging Coalition, which reviewed composting programs in 6,233 U.S. cities in 2025, covering about 60 percent of the population. The headline number is that 35.9 percent of the people in that sample have access to some kind of composting program, curbside or drop-off, public or private. That’s up from 27 percent in 2020, and the growth is real.
Now the number that matters for a restaurant. Of that 35.9 percent, roughly half, 17.8 percent, are in programs that accept food waste only. No packaging. The container goes in the trash no matter what it’s made of. The other 18.1 percent live where programs accept food waste and some forms of compostable packaging. “Some forms” is doing a lot of work. A program that takes fiber clamshells may refuse PLA cups. One that takes cutlery may refuse anything with a lining.
So the honest ceiling, before you account for any of that variation, is about one in five Americans. And that’s residential. Commercial accounts, which is what a restaurant is, run on a separate set of hauler contracts, and in most markets the answer to “will you take our compostable serviceware” is a phone call, not a policy.
I’m not saying this to discourage anyone. I’m saying it because the material only performs if it arrives at a facility built to handle it, and at most one in five Americans currently has that kind of program available to them at all — access, not proximity, and residential access at that. Commercial accounts are a separate question, answered case by case.
What the composters see
Composters are the customers of your customers’ waste, and their side of the story is the one operators almost never hear.
Closed Loop Partners ran a field study at ten U.S. compost manufacturers, sampling incoming feedstock and finished product. Two findings should reframe how you think about this. First, 85 percent of the contamination composters receive, by volume, is conventional plastic. Not compostable packaging. Ordinary plastic bags, film, and rigid items that somebody hoped would go away. Second, the study found most facilities had contamination problems whether or not they accepted compostable packaging. The compostable cup is not what’s clogging the screens.
On the other side of the ledger, eight of nine composters in the study that accept compostable products found no detectable compostable packaging in their finished compost. When certified material gets to the right facility, it does what the certificate says.
But contamination removal eats about 21 percent of a composter’s operating costs, and that’s the number that drives the decisions you feel. A facility that’s spending a fifth of its budget pulling plastic out of food scraps has every incentive to narrow what it accepts, because every new category is a new sorting problem. That’s why hauler acceptance lists are conservative, why they change, and why “certified compostable” and “accepted here” are two different sentences.
The label problem
Then there’s what you’re allowed to print on the box. Compostable labeling rules vary by state and are actively being rewritten in the states that regulate this most closely, including California. What counts as “compostable” for a bioplastic like PLA specifically is not fully settled yet, and the rule could look different a year from now than it does today.
I bring this up not to relitigate the policy. I bring it up because it tells you where the industry is: the definition of the word on the package is still being worked out between regulators, composters, and manufacturers. If you’re building a program around a label, know that the label itself is a moving target. Ask your supplier what standard a product is certified to, and check it against your state’s current rule before you commit to it in writing on a menu or a sustainability page.
Four questions before you switch
Here’s what I actually tell operators. None of it is about material. All of it is about the system.
Does your hauler take it, in writing? Not “we support composting.” A list, by item type, of what their facility accepts. Fiber clamshells, PLA cold cups, CPLA cutlery, lined hot cups, and bags are five different answers at most facilities. If you can’t get the list, you don’t have a program yet.
Where does the bin actually go? Front-of-house sorting is where most programs die. If guests dump everything in one bin, the compostable container and the ketchup packet and the plastic lid all go together, and a composter facing that 21 percent contamination cost will reject the whole load. A program that isn’t designed around how a guest disposes of a tray is a program designed to fail.
What’s your fallback where it isn’t accepted? Multi-unit operators need a second answer. In a market with no commercial composting, a recyclable rigid or a plain unlined fiber item is a more honest choice than a certified compostable that ends up in the same landfill but cost more to get there. Match the material to the waste reality at each address, not to the sustainability page on your website.
Can you prove it? Certification for the product, an acceptance letter from the facility, a photo of the back-of-house bins. That’s the paper trail that separates a real program from a marketing claim, and it’s what a skeptical guest, a journalist, or a procurement officer will ask for.
Where I land
I’m bullish on composting. Food waste is a major source of methane in landfills, and access has grown real ground over the last five years. Compostable packaging is the right long-term direction, and I’ve bet a company on that.
But direction isn’t the same as destination yet. The most valuable thing a supplier can do for an operator right now isn’t to sell them the greenest material. It’s to ask which system they’re joining, and say plainly when the honest answer is “none yet.”
Join the system first. Then buy the container.
