In 1938, a chemist at DuPont named Roy Plunkett accidentally discovered polytetrafluoroethylene — better known as Teflon. The carbon-fluorine bond at its core was among the strongest in organic chemistry, which made it extraordinarily useful. It repelled water and oil. It resisted heat and corrosion. It was, for all practical purposes, indestructible.
That indestructibility was the selling point. It is now the crisis.
Per- and polyfluoroalkyl substances — PFAS — are a family of more than 14,000 synthetic chemicals built around that same carbon-fluorine bond. They are in nonstick cookware, waterproof clothing, firefighting foam, food packaging, cosmetics, and semiconductor manufacturing. They are also in the blood of 98 percent of Americans, in rainwater on every continent, and in the drinking water of communities that never asked for them. They do not break down in the environment. They accumulate in living tissue. They are linked to kidney cancer, thyroid disease, liver damage, immune suppression, and developmental harm in children.
We called them "forever chemicals" because that is what they are. And the question now facing the chemical industry, regulators, and all of us is straightforward: what comes next?
The Tenth Principle
In 1998, Paul Anastas and John Warner published Green Chemistry: Theory and Practice, laying out twelve principles meant to guide the design of safer chemicals and processes. The tenth principle — Design for Degradation — is perhaps the most radical. It states that chemical products should be designed so that at the end of their function, they break down into innocuous degradation products and do not persist in the environment.
This is not a minor technical adjustment. It is a fundamental reversal of how industrial chemistry has operated for more than a century. The default assumption has always been that durability equals value. A coating that lasts longer is a better coating. A surfactant that resists breakdown is a superior surfactant. Design for degradation asks chemists to build an expiration date into their molecules — to create substances that are stable enough to do their job but unstable enough to disappear when that job is done.
The challenge is real. A coffee cup coating must resist hot liquid for the thirty minutes you are drinking from it but should not resist decomposition for the next three thousand years in a landfill. A textile treatment must repel rain during a hike but should not contaminate the watershed when the jacket is eventually discarded. This requires a level of molecular precision that was, until recently, beyond our capabilities.
It is no longer beyond them.
The Industry Begins to Move
3M, one of the largest PFAS manufacturers in history, completed its exit from PFAS manufacturing by the end of 2025. The company's February 2026 annual report confirmed the discontinuation of all fluoropolymer, fluorinated fluid, and PFAS-based additive production. Over the preceding three years, 3M removed PFAS from approximately 7,000 products — roughly one-third of its portfolio. The company still uses PFAS in some products where alternatives do not yet exist, particularly in lithium batteries, circuit boards, and gaskets, but the manufacturing phase-out represents a historic shift for a company that profited from these chemicals for decades.
3M is not alone. BYK Additives, a major specialty chemical producer, committed to ceasing all PFAS production and offering fluorine-free solutions by the end of 2025, including the conversion of its firefighting foam production facilities. The European Union, under its REACH 2.0 framework, is advancing toward a near-total PFAS ban. In the United States, the EPA finalized drinking water standards for several PFAS compounds, and individual states — Maine, Minnesota, California, and others — have enacted their own restrictions on PFAS in consumer products.
The market is responding accordingly. The PFAS-free fluoropolymer alternatives market reached an estimated $1.2 billion in 2026, with analysts projecting a compound annual growth rate of nearly 13 percent through 2036. The PFAS-free food packaging coating market alone is valued at approximately $389 million and projected to surpass $700 million by 2035.
These are not speculative figures. They represent actual capital flowing toward a post-PFAS future.
What the Alternatives Look Like
The most promising PFAS replacements share a common design philosophy: achieve the desired performance — water repellency, oil resistance, thermal stability — without the carbon-fluorine bond that makes PFAS permanent.
In food packaging, researchers at Northwestern University developed a graphene oxide-based coating that offers water and oil resistance comparable to PFAS treatments. Independent third-party evaluations conducted in early 2025 found that the coating increases barrier performance and paper strength by 30 to 50 percent compared to existing commercial solutions, at comparable cost. The material is non-toxic, compostable, and recyclable. A startup called GO-Eco, affiliated with Northwestern's Querrey InQbation Lab, is commercializing the product, with pilot-scale production trials underway. Major food service companies like McDonald's have already committed to removing PFAS from all guest packaging worldwide.
In textiles, fluorine-free durable water repellent coatings based on polyurethane technology, silicones, and bio-based polymers are entering the market. These coatings do not match the oil repellency of long-chain PFAS treatments in every application, but for the vast majority of consumer uses — rain jackets, outdoor furniture, footwear — they perform adequately. The outdoor apparel industry, led by companies like Patagonia and Gore-Tex, has been among the earliest adopters.
In industrial applications, high-performance thermoplastics such as polyether ether ketone (PEEK) and polyphenylene sulfide (PPS) offer the chemical resistance and thermal stability that manufacturers previously relied on PFAS to provide. These materials are not cheap, but they are degradable through controlled industrial processes, and they do not bioaccumulate.
Bio-based surfactants — rhamnolipids and sophorolipids derived from microbial fermentation — are replacing PFAS-based surfactants in industrial cleaning and oil recovery operations. Companies like Cyclopure have developed filtration polymers from renewable sugars that are both functional and biodegradable.
Perhaps most creatively, researchers at the University of Toronto demonstrated a technique they call "fletching" — decorating silicone polymers with small trifluoromethyl groups to improve oil repellency without using the long fluoroalkyl chains that make traditional PFAS persistent. The approach uses fluorine, but in forms that are orders of magnitude less persistent and less toxic than conventional PFAS chemistry.
The Gaps That Remain
Honesty requires acknowledging that a post-PFAS world is not yet fully achievable. An online database maintained by the American Chemical Society, updated in February 2025, identifies more than 530 potential alternatives across 40 applications — but also flags 83 applications where safer substitutes do not yet exist.
Semiconductor manufacturing is one. The extreme purity and chemical resistance requirements of chipmaking still depend on fluoropolymers for which no adequate replacement has been demonstrated at scale. Medical devices present similar challenges; while companies like Biocoat Inc. have developed PFAS-free hydrophilic coatings for some applications, implantable devices and surgical instruments often require properties that only fluorinated materials currently provide.
Firefighting foam remains a difficult transition. The EU has adopted regulations phasing out PFAS in firefighting foams by 2030, but fluorine-free foams — known as F3 foams — still face questions about performance on large-scale hydrocarbon fires. Military and aviation applications present the highest bar, where failure to suppress a fire can mean loss of life.
These are not arguments against the transition. They are arguments for targeted investment in the specific applications where gaps remain, rather than blanket delays that protect the status quo.
Design for Degradation Is Not Just About PFAS
The post-PFAS transition is the most visible application of design for degradation, but the principle extends far beyond forever chemicals. Pharmaceuticals that persist in waterways, pesticides that accumulate in soil, microplastics that fragment but never truly decompose — all of these represent failures to design for end-of-life.
The principle asks a question that should be asked of every synthetic molecule before it enters commerce: what happens to this substance after it has done its job? If the answer is "nothing — it persists indefinitely," then the design is incomplete. A chemical that works perfectly but never goes away is not a finished product. It is a deferred liability.
Green chemistry does not demand that we abandon high-performance materials. It demands that we include degradation in our definition of performance. A coating that repels water for five years and then biodegrades into carbon dioxide, water, and mineral salts is not inferior to one that repels water for five years and then contaminates groundwater for five centuries. It is superior. We simply did not used to measure performance that way.
What the EPR Foundation Believes
We believe the post-PFAS transition is not optional. It is happening — driven by regulation, litigation, market demand, and the basic reality that contaminating the blood of every person on Earth is not a sustainable business model.
We also believe that design for degradation should become a standard requirement in chemical regulation, not an aspirational principle. Every new synthetic chemical entering commerce should be required to demonstrate a plausible degradation pathway under environmental conditions. The burden of proof should fall on the manufacturer, not on the communities that discover contamination decades later.
The science is available. The alternatives are emerging. The capital is flowing. What remains is the will to treat the end of a chemical's life with the same rigor we apply to its beginning.
The strongest bond in organic chemistry built the most persistent pollutant in human history. The next generation of chemistry must be measured not by what it creates, but by what it leaves behind.
