As evidence mounts that hamburger wrappers and other kinds of grease-proof packaging contaminate food with PFAS, states have started banning the toxic chemicals from food packaging.
Now, a new report provides yet another reason to remove PFAS, or perfluoroalkyl and polyfluoroalkyl substances, from food wrappers: climate and ozone pollution.
PFAS exposure is linked to immune and developmental system effects, increased risk of preeclampsia in pregnant women, increased risk of kidney and testicular cancers, and higher cholesterol, among other health effects. The Daikin America plant in Decatur, Alabama, which manufactures PFAS used to coat food packaging and textiles, released 240,584 pounds of the ozone-depleting chemical Chlorodifluoromethane (HCFC-22) — the global warming equivalent of one billion pounds of carbon dioxide — in 2019, according to a new report out Thursday from the nonprofit Toxic-Free Future.
While HCFC-22, used in refrigeration, was banned at the start of last year under the Montreal Protocol, companies are still allowed to produce the compound as a byproduct of making other substances. Advocates say the new report highlights the need to close that loophole — and to use PFAS-free food packaging alternatives.
“The entire world is scrambling to reduce greenhouse gas emissions before their damage to our climate is beyond repair, yet we are letting a company dump hundreds of thousands of pounds of hydrochlorofluorocarbons into the atmosphere so that it can produce ‘forever chemicals’ that poison our communities?” Peggy Shepard, executive director of the nonprofit WE ACT for Environmental Justice, who was not involved in the report, said in a prepared statement. “Where is the justice in that?”
Far-reaching Impacts of PFAS Production
The impetus for the study was to learn more about the impacts of PFAS-containing products before they get to consumers or end up in landfills, Erika Schreder, science director of Toxic-Free Future, told EHN. The researchers found that there appears to be only one plant in the U.S. that makes PFAS for fast food packaging coating.
Daikin America, which also emits 55,000 pounds a year of the carcinogen tetrafluoroethylene, is the number two emitter in the country of HCFC-22 after the Chemours chemical manufacturing plant in Louisville, Kentucky, according to the report.
The authors also looked at the upstream pollution from the paper mills that coat food packaging with Daikin’s PFAS product, estimating that each mill releases around 180 pounds of PFAS a day into waterways, with an additional 1,260 pounds ending up in sludge at wastewater treatment plants. “We have to remember that whenever PFAS is used, it’s part of the drinking water contamination problem,” said Schreder, noting that landfills have been a major source of PFAS pollution around the country.
Health Problems Near PFAS Plant
Decatur’s PFAS manufacturing plant was originally built in 1961 by 3M, which sold the facility to Daikin America in 2014. Concerns about the plant, and other factories in the industrial area, have been around for decades, Brenda Hampton, a local resident and founder of Concerned Citizens of WMEL Water Authority, told EHN. Hampton and her mother both experienced kidney failure, and residents have come down with unusual forms of cancer and respiratory problems, she said.
Federal health authorities have tied elevated levels of PFAS in residents’ blood to drinking water contamination downstream of that and another area plant, with Daikin agreeing to pay the local water authority $5 million in 2017 to help pay for a water filtration system, according to the report.
Last month, an employee at the Daikin America plant died after being exposed to dangerous chemicals on the job, local TV station WAFF-48 reported. Last year, OSHA fined the company $40,482 for alleged hazardous chemical management and respiratory protection violations, according to the new report.
“In this day and time, we should have [jobs and food] out there that won’t be as toxic to people,” said Hampton.
The report authors issue a number of recommendations, such as manufacturers paying for PFAS cleanup in affected communities, the EPA banning the production of HCFC-22 as an intermediary in PFAS manufacturing, and restaurant chains removing PFAS from food wrappers. With PFAS already banned from food packaging in states including Washington and Connecticut, some chains, like McDonald’s, have recently agreed to phase out PFAS-coated packaging.
EHN has reached out to Daikin for comment on the new report.
We’re not backing down in the face of Trump’s threats.
As Donald Trump is inaugurated a second time, independent media organizations are faced with urgent mandates: Tell the truth more loudly than ever before. Do that work even as our standard modes of distribution (such as social media platforms) are being manipulated and curtailed by forces of fascist repression and ruthless capitalism. Do that work even as journalism and journalists face targeted attacks, including from the government itself. And do that work in community, never forgetting that we’re not shouting into a faceless void – we’re reaching out to real people amid a life-threatening political climate.
Our task is formidable, and it requires us to ground ourselves in our principles, remind ourselves of our utility, dig in and commit.
As a dizzying number of corporate news organizations – either through need or greed – rush to implement new ways to further monetize their content, and others acquiesce to Trump’s wishes, now is a time for movement media-makers to double down on community-first models.
At Truthout, we are reaffirming our commitments on this front: We won’t run ads or have a paywall because we believe that everyone should have access to information, and that access should exist without barriers and free of distractions from craven corporate interests. We recognize the implications for democracy when information-seekers click a link only to find the article trapped behind a paywall or buried on a page with dozens of invasive ads. The laws of capitalism dictate an unending increase in monetization, and much of the media simply follows those laws. Truthout and many of our peers are dedicating ourselves to following other paths – a commitment which feels vital in a moment when corporations are evermore overtly embedded in government.
Over 80 percent of Truthout‘s funding comes from small individual donations from our community of readers, and the remaining 20 percent comes from a handful of social justice-oriented foundations. Over a third of our total budget is supported by recurring monthly donors, many of whom give because they want to help us keep Truthout barrier-free for everyone.
You can help by giving today. Whether you can make a small monthly donation or a larger gift, Truthout only works with your support.
