Compostable packaging needs to go to an industrial composting facility to break down properly, not into your backyard compost bin or regular trash. The most important step is checking the certification label on the package, because “compostable” doesn’t always mean what you’d expect, and the wrong disposal method can mean it never breaks down at all.
Check the Label First
Before you do anything, look for a certification mark on the packaging. In the U.S., the main one is the BPI Certification Mark, a small logo that confirms the product meets recognized composting standards. BPI-certified products are required to display this mark so consumers can distinguish them from non-compostable lookalikes. If you see “compostable” printed on packaging but no certification logo, treat that claim with skepticism.
There are two categories of compostable packaging, and they require very different disposal paths. Industrially compostable (sometimes called commercially compostable) packaging is designed to break down at a large-scale facility that controls temperature, moisture, and airflow. Home compostable packaging meets a stricter standard: it must degrade 90% within 12 months at temperatures around 25°C (77°F), which is roughly what a backyard pile reaches. Industrial composting operates at much higher temperatures, around 58°C (136°F).
In the U.S., there is no North American certification standard for home compostability. Some states have stepped in with their own rules. California and Maryland both require products labeled “home compostable” to carry OK compost HOME certification from TÜV Austria. If your packaging doesn’t specify “home compostable” with that certification, assume it needs an industrial facility.
Finding an Industrial Composting Facility
Most compostable packaging is designed for industrial composting, so your next step is figuring out whether you have access to one. A 2023 nationwide survey of composting facilities found that 71% of responding operations accept compostable food-contact packaging. That’s up from previous years, and 62% now accept certified compostable bioplastic items like cups and cutlery, compared to just 48% in 2018. Access is growing, but it’s far from universal.
Start with your municipal waste program. Many cities now offer curbside organics collection or drop-off sites that feed into industrial composting. Check your city or county’s waste management website for what they accept. Some programs take compostable packaging alongside food scraps; others limit collection to food and yard waste only. If your area doesn’t offer curbside pickup, search for commercial composting drop-off locations nearby. Grocery stores, farmers’ markets, and community gardens sometimes serve as collection points.
One important detail: even facilities that accept compostable packaging may not break it down completely if they run short composting cycles. A facility operating on a 30-day turnaround may find that packaging hasn’t fully decomposed by the time the batch is finished. Windrow composting, where material sits in long rows turned periodically, generally allows more time than aerated static pile systems. You don’t need to investigate your local facility’s methods, but it helps explain why some compostable items occasionally survive the process.
Prep Before You Compost
Before tossing compostable packaging into your organics bin, remove anything that isn’t compostable. Peel off shipping labels, stickers, and any conventional packaging tape. These are typically made from plastic or have plastic-based adhesives that won’t break down. Some brands sell compostable stickers and tape, and those can stay on. When in doubt, remove it.
Rinse off heavy food residue if your collection program asks you to, though most composting facilities can handle food-soiled packaging. In fact, that’s one of the main advantages of compostable food packaging: it can go straight into the compost stream with leftover food rather than contaminating recycling. Tearing or cutting larger items into smaller pieces can speed up breakdown, especially for thicker materials like molded fiber containers.
Why Landfills and Recycling Bins Don’t Work
Throwing compostable packaging in the trash sends it to a landfill, where it won’t decompose the way it’s designed to. Landfills are anaerobic environments, meaning there’s very little oxygen. Organic materials that break down without oxygen produce methane, a greenhouse gas far more potent than carbon dioxide. The EPA estimates that 58% of fugitive methane emissions from municipal landfills come from organic waste. Compostable packaging in a landfill behaves like any other organic material trapped without air: it either sits there indefinitely or contributes to methane production.
Putting compostable packaging in your recycling bin is equally problematic. Compostable bioplastics look similar to conventional plastics but have a completely different chemical makeup. When they enter a recycling stream, they contaminate batches of recyclable material, reducing the quality of recycled plastic. This is exactly why certification marks matter: they help sorting facilities and consumers keep these materials in the right stream.
Home Composting: What Actually Works
If you compost at home, only add packaging explicitly certified as home compostable. Industrially compostable packaging will not fully break down in a backyard bin. Your pile simply doesn’t get hot enough or stay hot long enough. Home compost piles typically hover around ambient temperatures, while industrial facilities sustain heat well above 50°C for extended periods.
Items that tend to work well in home compost include uncoated paper bags, certified home-compostable mailers, and plain cardboard without glossy coatings. Compostable bioplastic cups, cutlery, and lined containers almost always require industrial processing. Tear paper-based items into smaller pieces, mix them into your pile with food scraps and yard waste, and keep the pile moist and aerated. Even certified home-compostable packaging can take up to 12 months to fully break down, so be patient.
The PFAS Factor
Compostable food packaging once had a hidden problem: PFAS, a group of synthetic chemicals often called “forever chemicals” because they don’t break down in the environment. These were used to make packaging grease-resistant. In 2020, the FDA announced a voluntary phaseout of the most common PFAS compounds used in food packaging. That same year, BPI stopped certifying any products containing PFAS. Several states have gone further with outright bans. Maine, for example, is expanding its ban on PFAS in consumer products starting January 2026.
This matters for composting because PFAS can persist in finished compost and end up in soil. If you’re composting at home, especially in a garden where you grow food, choosing packaging from brands that are BPI-certified (post-2020) gives you reasonable confidence the product is PFAS-free. Older compostable packaging or uncertified products may still contain these chemicals.
Quick Reference by Packaging Type
- Compostable bioplastic cups and cutlery: Industrial composting only. Look for the BPI mark. Do not place in recycling.
- Compostable mailers and bags: Check for home compostable certification. Remove non-compostable labels and tape before composting.
- Molded fiber containers (takeout boxes, egg cartons): Usually industrially compostable. Uncoated versions may work in home compost, but coated versions need a facility.
- Paper packaging with a bioplastic lining: Industrial composting. The lining won’t break down in a home pile.
- Compostable trash bags: Useful as liners for your kitchen organics bin, then sent to industrial composting with the contents. Most don’t break down fast enough for home compost.
If no composting option exists in your area, compostable packaging unfortunately ends up in the trash. It’s not ideal, but it’s better than contaminating recycling. The most effective thing you can do in that situation is advocate for curbside organics collection in your municipality, since the infrastructure gap remains the biggest barrier to getting these materials composted properly.
