Policy change: no more compostable plastics

Update Jan 31, 2026: At long last, we’ve begun composting on our own property. We’ll conduct bioplastic testing soon and hope to allow compostable plastics again by the end of the year!

We were recently informed by the commercial compost facility that processes all the food waste we collect, that they are no longer accepting certified compostable plastics. Our understanding is that these items, particularly the bags and cups, have not been breaking down sufficiently, and their staff are wasting a lot of time picking them out of the finished piles.

Consequently, we must change our own policy and stop accepting these materials as well.

When does this go into effect?

The change has already gone into effect for their’ other customers, but they’ve kindly granted us a grace period to use up our remaining bag liners and to educate our members about the change.

Providing a specific date is challenging for us, since we have customers on a variety of different pickup frequencies and a bucket that goes out with a compostable liner might not find it’s way back to us for more than a month.

So instead of a specific date, we’re going to let the buckets do the talking: as long as your bucket arrives with a liner, you can continue adding certified compostable plastics. But once your bucket arrives without a liner, it’s time: no more bioplastics. You can also watch for a red sticker on your lid, though those may lag behind the change due to a printing delay.

What items are affected?

This change means we can’t accept ANY compostable plastics anymore. The most common items we see include:

• Compostable plastic serviceware, including cutlery, cups and bowls.
• Paper serviceware lined with compostable plastics, including coffee cups and soup/hotbar containers.
• Compostable plastic bags, including liners, produce bags, and niche shipping bags.
• Compostable K-cup rings (though you can tear off the ring and compost the contents).

What does this mean for residential pickup & dropoff members?

• You will no longer receive a compostable liner with your bucket. We encourage you to line your bucket with used paper grocery bags, to keep it tidier for you and to facilitate cleaning for us. You can also just put your scraps directly into the bucket.
• In the coming days we’ll invite our residential pickup members to complete a survey about this change and how it will impact our service in both the immediate future and in the long term.
• Compostable plastics found in your bucket will be flagged as contamination, and repeat offenses may result in termination of service.
• We ask for your patience as we refine our washing procedures in light of the much dirtier buckets we’ll be receiving. If we encounter difficulties with persistent odors or residues, we may need some time to experiment with different earth-friendly soaps.

What does this mean for commercial customers?

• Your containers will no longer be lined with compostable bags.
• The reduced “bag-only” fee for roll carts will no longer be an option.
• Compostable plastics in your compost containers will be treated as contamination, including the escalating contamination fees listed in your service agreement.

Closing thoughts

Bioplastics have always been controversial. “Biodegradable” plastics are blatant greenwashing by the petroplastic industry, while “compostable” plastics are of questionable environmental benefit. In both cases, most of them end up either in the landfill or contaminating recycling streams… only a small percentage of compostable plastics actually find their way to a facility capable of composting them.

Of course, they are also incredibly convenient. It’s obviously much easier to replace a single-use plastic with a compostable equivalent than to switch away from single-use items entirely. We have treasured the bags we’ve used the past 5.5 years, as they’ve kept our buckets and other containers much cleaner than they’ll be without liners. And we’ve been grateful for how they’ve reduced our water consumption.

But… these bioplastics were always a guilty pleasure for us. In the end, we won’t be party to greenwashing or wishcycling, so if they aren’t breaking down like they’re supposed to, then we can’t let our members keep using them. We’re always reminding our customers that recycling, including composting, is fundamentally a local issue: what you can recycle or compost in your area depends entirely on your local infrastructure. So if our facility says that bioplastics aren’t working, then the bioplastics have to go.

This will be a chaotic transition for all of us, but we’ll get through it. Thank you in advance for your patience, and happy (messy) composting!
