Firefighting foams contain toxic PFAS. Could soybeans be the answer?
This story was originally published by Grist and appears here as part of the Climate Desk collaboration Jeff King has served on the volunteer fire department in Corydon, Kentucky, for over 30 years. He is well aware of the dangers of the job — including one that may be hiding in the supplies he and his crew use to keep others safe. Many of the foams firefighters spray to extinguish blazes contain per- and polyfluoroalkyl substances, or PFAS. Known as 'forever chemicals,' PFAS are a class of human-made chemicals that repel water and oil; it's this quality that makes them effective at battling tough-to-put-out fires, like those started with diesel fuel. The chemicals are also tied to a host of human health problems, from reproductive issues to high cholesterol to certain types of cancer. King admits that some of the foams he's used over his career 'may or may not be good for us.' That's why he visited Dalton, Georgia, last year to meet with representatives from Cross Plains Solutions, a company that developed a PFAS-free firefighting foam made from soybeans. After seeing the foam in action, he was impressed. 'The product performs just fantastic,' said King. And because it has been certified as PFAS-free, he figured, 'there's nothing in it that could potentially make me or any other firefighter in this country that uses it sick. I just thought, 'Wait a minute, this is almost a no-brainer.'' There's another upside for King in all of this: In his day job, he's a soybean farmer himself. A new application for the humble soybean would be good for business. The search to find a PFAS-free firefighting foam is relatively new, as a growing body of research illuminates the harmful impact that these chemicals have on humans and the environment. Soybean farmers have presented their crop as a surprising solution to this problem. Although more research and development are needed to ensure soy-based firefighting foam holds up under the toughest circumstances, the product is catching the attention of local fire departments. 'There is a good bit of interest,' said Alan Snipes, CEO of Cross Plains Solutions. He estimated that his company's product, aptly named SoyFoam, is now being used in 50 fire departments around the country, mostly in the Midwest. That's not a coincidence: Snipes pointed out that many rural fire departments in the middle of the country depend on volunteer firefighters. 'A lot of the volunteers are farmers, and a lot of the farmers grow soybeans,' he said. Cross Plains began to look into creating a PFAS-free, soy-based firefighting foam after being approached by the United Soybean Board. Snipes was first in touch with the board more than 30 years ago, when he worked in the carpet industry and started using soy-based compounds to manufacture backing for commercial carpets. He started Cross Plains Solutions about 13 years ago to produce a bio-based cooling gel for mattresses. Then, three years ago, the United Soybean Board offered the company funding to develop and test a biodegradable firefighting foam. The board, whose members are appointed by the US Department of Agriculture, exists to collect one-half of one percent of the market price of every bushel of soybeans sold by US farmers. This congressionally mandated process, called the soybean checkoff program, is used to fund research into new markets for soybeans. The United Soybean Board partners with both public and private actors, like universities and corporations, to fund research into and commercialization of new soybean uses. Often, this looks like investing in more sustainable alternatives to fossil fuels — like using soybean oil as a petroleum replacement in tires, straws, and shoes. In a partnership like the one with Cross Plains, the checkoff program is hoping to create a business opportunity that might help farmers sell more bushels down the line. The result is a 'win-win,' said Philip Good, chair of the United Soybean Board. After King returned home to Kentucky, his fire department voted to exclusively use SoyFoam going forward; according to King, it was the first in the country to do so. SoyFoam is not unique. There are other alternatives to PFAS-based firefighting foams on the market with different formulations and applications, said Danielle Nachman, a senior staff scientist at the Johns Hopkins University Applied Physics Laboratory. 'They can span all kinds of chemistry,' said Nachman. Some are bio-based, like a gel made with canola oil, while others try to replicate the chemical properties of PFAS without relying on fluorinated compounds. The big hurdle for SoyFoam and other PFAS-free firefighting foams is meeting requirements set by the Department of Defense for military firefighting and training activity. PFAS-containing firefighting foams were first patented by the United States Navy in the 1960s, following a series of devastating fires on aircraft carriers and other ships. In the 1970s, virtually every US military base began using these foams for emergencies and training exercises — leading to dangerous contamination in the surrounding areas. 'The majority of the headache when it comes to PFAS [in firefighting foams] is the military application,' said Mohamed Ateia Ibrahim, an adjunct assistant professor of chemical and biomolecular engineering at Rice University, 'because of all of the military bases and the training activities.' The Department of Defense has been working to transition away from firefighting foams that contain PFAS — but SoyFoam has a ways to go before it could be fully embraced by the military. The Pentagon has not tested Cross Plains Solutions' product, but Snipes said the agency has encouraged the company to seek further funding to continue its R&D. The Department of Defense didn't respond to Grist's request for comment. Ibrahim said he supports the development of bio-based, PFAS-free foams, but that companies need to be more transparent about what exactly goes into their products. 'We need more clarification about the other components and whether they are, as a whole, really better or not' than PFAS-based firefighting foams, said Ibrahim.

Firefighters see effectiveness of soybean based foam
HENDERSON COUNTY, Ky. (WEHT) — Firefighters say a soybean-based foam is keeping them safe while also helping the environment. ' There is no poly-fluoroalkyl and no carcinogens. What we do out here is dangerous enough and we do not need the added risk of contracting cancer,' says Jeff King, a lifelong farmer and assistant chief at Corydon Civil Defense Fire and Rescue. It's called 'SoyFoam' and Corydon Civil Defense Fire and Rescue began using it last summer, instead of traditional foam. King says it works the same as traditional foam and comes at the same price. He says he has not seen any difference in how they fight fires, and says it adds a layer of safety. 'We did not have to change a thing, or tactics, equipment, or anything. It is business as usual. But when we leave we know we are not contaminating the ground or groundwater,' King says. The main difference is how it is made. Traditional foam is made with P-FAS and other forever chemicals. According to the U.S Environmental Protection Agency, P-FAS is being found all over the country, in water, air, fish, and soil. Exposure to it is linked to several adverse health effects, including certain cancers, thyroid dysfunction, and changes in cholesterol. 'SoyFoam' is made with U.S soy flour, which King says is safer for first responders, helps keep soil, air quality, and drinking water safe, and is a win for farmers. 'It helps farmers use excess soybean meal that we have in our country,' King says. King says it is gaining attention. He says the Henderson City fire department and departments in Daviess County are all looking at making the switch. He also says he got a call from a chief from Kuttawa, Kentucky which is about 61 miles away from the station in Corydon and is dealing with flooding. 'They say it is a product they will be able to use around water shed areas and not have to worry about contaminating the lakes,' King says. King says 'SoyFoam' will help keep generations of firefighters safe, including his 16-year-old nephew. 'He is a junior firefighter. This is one less thing I have to worry about… him sometime down the line, getting sick,' King says. King says any fire departments who want to learn more about 'SoyFoam' can contact Corydon Civil Defense Fire and Rescue or the Kentucky Soybean Board in Princeton, Kentucky.
