Within the bottle processing plant in Reidsville, North Carolina, drifts of plastic particles, like snow banks, are piled in each nook of the equipment that chops the bottles into flake. Once I ask our tour information, a flooring supervisor, if he worries about respiratory it in, he says he does not. “We do an excellent job of cleansing it up,” he says, including that the luggage of mud which can be vacuumed up are bought off, and the wastewater is filtered.
However I’m involved. A 2023 examine of a UK plastics recycling plant discovered that even after the set up of state-of-the-art filters, round 6 % of the plastic being processed was launched into the wastewater as micro and nanoplastic, whereas the air across the facility was filled with microplastics sufficiently small to be hazardous to human well being.
Scientists are nonetheless puzzling out what microplastics do to our well being, however one examine discovered that individuals with IBS tended to have extra microplastics, together with PET and polyamide (of which nylon is one kind), of their intestine. Whereas PET appears to be one of the vital benign out of all of the plastics, at the least two research have discovered BPA, a hormone-disrupting chemical, in polyester child clothes, and a lot of manufacturers agreed to a settlement with California lawmakers in 2023 over the presence of BPA in polyester athletic shirts.
As well as, water utility managers in Reidsville have alleged that Unifi and different polyester producers could possibly be probably be sources of 1,4-dioxane, a possible human carcinogen, within the Cape Worry watershed, which offers ingesting water for over 1 million folks because it flows from central to southeast North Carolina. Technically, that’s not unlawful (particularly since Unifi, together with different industrial sources and several other cities, efficiently lobbied in opposition to a North Carolina rule limiting 1,4-dioxane in wastewater). As a result of 1,4-dioxane is a byproduct of producing PET resin, the EPA declared in late 2024 that nearly any publicity to 1,4-dioxane constitutes an unreasonable threat to the well being of polyester staff and surrounding communities. There are (very expensive) methods to deal with wastewater for 1,4-dioxane, so how ensuing rules would have an effect on Unifi stays to be seen, particularly for the reason that EPA doesn’t at present appear eager to do any regulating of poisonous chemical publicity.
Ingle and Boyd each declined to talk intimately about these points. In individual, they cited the recommendation of Unifi’s counsel (BPA), stated Unifi follows all rules (1,4-dioxane), or pled ignorance (microplastics). Comply with-up inquiries to Boyd went unanswered. Ingle responded to follow-up questions by way of e-mail by writing, “We keep lively participation in The Microfibre Consortium, so as to assist tutorial and trade analysis into the supply and influence of fiber fragmentation from textiles into the pure surroundings.” And “We’re compliant with all native, state, and federal rules for all of our websites.”
To advocates, every micro-scandal is proof that there isn’t any environmentally pleasant polyester. “We won’t do that sustainably in a unhazardous approach, it is actually not possible,” Pecci says.
However I left the Repreve plant questioning if we’re letting good be the enemy of excellent American jobs. Polyester will proceed to be in demand, and it’ll both be made right here in a compliant manufacturing unit utilizing recycled sources, or overseas in a sketchy manufacturing unit utilizing contemporary petrochemicals. Pecci says she doesn’t need to “name out that firm or these folks, as a result of they is likely to be the nicest folks on the earth doing one of the best they will with what they’ve.” She described for me a utopia by which unhazardous and pure clothes is all made right here after which composted and recycled right here. Sounds beautiful, and not possible.
In February of this 12 months, Unifi introduced it was closing its Madison, North Carolina, polyester processing plant. It could ship a few of its equipment to its Latin American crops, and provide the Madison staff new job alternatives on the Yadkinsville and Reidsville crops, which stay in service.
For now, anyway.
