Poke round a typical workplace at noon, and also you’re prone to see not less than just a few compostable fiber bowls from eating places like Chipotle and Sweetgreen holding your coworkers’ lunches. As fast-casual chains compete for patrons in cities throughout the U.S., many corporations tout these eco-friendly containers as a method to model themselves as environmentally accountable. However an investigation by The New Meals Economic system calls these claims into query: These supposedly compostable bowls are made with fluorinated compounds, known as PFAS, that don’t ever break down naturally and will carry severe public well being dangers.

Within the investigation, The New Meals Economic system collected samples of compostable takeout containers from 14 totally different eating places in New York Metropolis together with Sweetgreen, Chipotle, and Dig Inn. The samples have been despatched to Graham Peaslee, a chemist on the College of Notre Dame, who examined them utilizing a sort of ion beam evaluation known as Particle-Induced Gamma-ray Emission. These assessments revealed the whole quantity of fluorine within the samples, not the precise sorts of PFAS discovered inside them. Nonetheless, it’s a dependable method to decide if one thing has been handled with fluorinated compounds like PFAS. And the outcomes have been compelling: Of the containers sampled, the bottom confirmed 826 elements per million (ppm) of fluorine, whereas the very best registered 2,167 ppm—on common, the samples had fluorine ranges 50 instances greater than the management group.

Rainer Lohmann, director of the College of Rhode Island’s Lohmann Lab, which research the results of poisonous chemical substances on waterways, advised The New Meals Economic system that the methodology was sound.

“The check Graham does is a good screening software,” he stated. “If a product is displaying actually excessive fluorine ranges, corporations actually can’t declare they didn’t use PFAS.”

These are troubling outcomes as a result of PFAS chemical substances aren’t biodegradable. Satirically, that’s why they’re utilized in takeout containers to start with—PFAS are impervious to grease and water, and so they preserve fiber containers from dissolving when stuffed up with meals. That additionally means the containers are solely partly compostable: The plant-based fibers will break down into compost, however PFAS will stick round eternally, infiltrating the soil and even leaching into ingesting water after the containers are thrown out.

As well as, PFAS aren’t with out well being dangers. A number of forms of PFAS, known as long-chain PFAS, have been banned by the FDA after they have been linked to a variety of well being points like kidney and testicular most cancers, low start weight, thyroid illness, and extra. Different forms of PFAS, known as short-chain PFAS, are nonetheless authorized, however their well being results aren’t solely understood. In accordance with specialists cited by The New Meals Economic system, short-chain PFAS can stick round within the human physique for a interval of some days to a couple months. If you happen to eat takeout frequently, you’re possible ingesting these chemical substances a lot sooner than your physique can eliminate them.

PFAS-laden containers pose an excellent higher menace as soon as they’re thrown away. For the reason that PFAS doesn’t break down, it stays current in compost and might then be absorbed by vegetables and fruit fertilized utilizing that batch of compost. If the container goes to a landfill, the PFAS stays within the soil and might make its approach into groundwater. Present filtration expertise isn’t in a position to seize PFAS, so any chemical substances that enter public water techniques will find yourself popping out of taps, too.

“That’s the most important challenge with PFAS in my thoughts,” Peaslee advised The New Meals Economic system. “The truth that we are actually contaminating our waterways. If you happen to don’t eat it off your wrapper, you and your youngsters will probably be ingesting it out of municipal water in two months. That’s the scary half.”

In response to new findings in regards to the prevalence of PFAS, the Biodegradable Merchandise Institute, which certifies merchandise as compostable, has up to date its standards to mandate that compostable merchandise comprise lower than 100 ppm whole flourine—roughly the quantity discovered within the management group in The New Meals Economic system‘s investigation. The brand new guidelines take impact in January 2020.

Till then, you may need to suppose twice about ordering that takeout salad. If you happen to do eat out, attempt in search of meals which can be served in PFAS-free containers, like cardboard packing containers lined with plant-based plastic. After all, you’ll be able to all the time simply make your individual lunch, too.
