The Problem
Floral foam has been a staple of the floral industry since the 1950s. It holds water, keeps arrangements in place, and is used in massive quantities, especially at events like weddings, which can burn through an entire dumpster trailer's worth of the stuff. The problem? Traditional floral foam is a single-use plastic destined for landfill, and it breaks down rapidly into microplastics while also releasing harmful chemicals.
With HHS's recent announcement of STOMP, the Systematic Targeting of MicroPlastics initiative, flagging microplastics as a growing threat to human health, the floral industry's hidden waste problem is getting a much-needed spotlight.
The Solution
Phoam Labs CEO and co-founder Dundee Butcher began her career in the flower industry in London, where she witnessed firsthand the hidden cost of traditional floral foam and asked a simple question: is there no better way?
After moving to California, she connected with Professor Marc Hillmyer, Director of the NSF Center for Sustainable Polymers at the University of Minnesota. Recognizing the potential of plant-based polymers as a sustainable replacement, a research partnership was formed. Over the next several years, a team of scientists and engineers worked to reinvent floral mechanics.
In Spring 2022, patents were granted for a groundbreaking, plant-based, compostable floral foam phoamlabs built from polylactide (PLA), a material derived from corn that is fully renewable within a 12-month cycle. The product generates zero microplastics, contains no harmful chemicals, and works as both a wet and dry foam. Florists don't have to sacrifice function for sustainability.
The Milestones
The momentum behind Phoam Labs is real and documented. In 2022, they won the MN Cup, the largest startup competition in the US, competing against 2,600 early-stage companies. In 2023, they took home the Sustainability Prize for Best New Product at the Interflora World Cup. In December 2024, Phoam Labs received TUV Industrial Compostability Certification, confirming a certified, compostable, non-toxic foam with a clear end-of-life solution. The product breaks down in 25 days under industrial composting conditions. You can even grow plants in it.
The Bigger Picture
The science and engineering potential here extends well beyond floral foam. The same PLA-based technology could be applied to other single-use foam products, from food trays to packaging, giving entire industries a viable, compostable swap. Phoam Labs describes their mission as an "earth-to-earth commitment," working alongside a global community of florists and designers committed to diverting green waste to composting sites rather than landfills. phoamlabs
With STOMP putting microplastics front and center in the national conversation, the timing couldn't be better for what Phoam Labs has spent over a decade building.
Why This Matters to Us
At Bottleless Nation, our whole existence is built around one core belief: plastic doesn't have to be the answer. We got into this business because single-use plastic water bottles are one of the most unnecessary sources of plastic waste in the workplace, and we built a better alternative. But we're not the only ones asking that question.
Stories like Phoam Labs remind us that the shift away from plastic is happening everywhere, driven by people who looked at a long-accepted norm and decided to do something about it. That's a movement, not just a product category. We share stories like this because we want our audience to see the full picture. Microplastics aren't just a water problem. They're showing up in floral foam, in food packaging, in the soil, in the air. The more industries that commit to rethinking plastic, the better the outcome for everyone.
