FPG Study: Fluoropolymers at their End-of-Life
Why is it important to consider the end-of-life of fluoropolymers?
The End-of-Life study was commissioned by the Fluoropolymers Product Group (FPG) in response to a gap in current scientific and policy understanding. While PFAS regulation in the EU has gathered momentum, it has largely treated fluoropolymers as interchangeable with other substances of the PFAS group, without accurately accounting for their differing chemical characteristics and their diverse treatment, waste and emissions profiles.
Scientific literature has long recognised that fluoropolymers are structurally and chemically distinct from the non-polymeric PFAS that have driven regulatory concern, yet comprehensive data on their occurrence in waste streams, their treatment, and the practical constraints on recovery had not been assembled in one place. As was the case with also assessing alternatives for fluoropolymers, this is the product of the innate complexity of assessing fluoropolymers distinctly due to their use as components in much larger, complex products. Prepared by Ramboll, this study draws on a systematic literature review, full-scale incineration stack testing data from European and US facilities, and a stakeholder survey of value-chain participants to fill that void.
The findings offer policymakers a factual basis for understanding the real-world environmental footprint of fluoropolymers at end-of-life, highlighting their nature as not an unacceptable risk and reinforcing the argument that they be fully exempt from any blanket restriction of PFAS.
One material, thousands of applications, diverse waste streams
From semiconductor manufacturing and aerospace components to electric vehicle batteries and industrial chemical processing, fluoropolymers fulfil performance-critical functions across sectors at the heart of Europe’s industrial base. As the EU’s chemicals framework evolves, the question of what happens to these materials once products are retired has taken on new significance.
This report answers that question with precision, mapping the routes through which fluoropolymers move at end of life, evaluating how effectively current treatment systems handle them, and placing their contribution to the wider waste picture in quantitative perspective.
Scope of the study
The report is based on:
It examines fluoropolymers’ occurrence in waste streams, treatment routes under the EU waste hierarchy, mineralisation performance, recycling feasibility, and their contribution to waste prevention through extended product lifetimes.
Key Findings
- Fluoropolymers are negligible as a waste stream
Approximately 23,500 tonnes of fluoropolymer-containing waste are collected annually in the EU, corresponding to less than 0.01% of total EU waste by mass. They are not collected or treated as a separate waste fraction but remain embedded in complex products whose end-of-life treatment determines their fate. - Thermal treatment is highly effective
Hazardous waste incineration is the dominant end-of-life route (~50%), achieving destruction efficiencies exceeding 99.9999% under regulated conditions. Water-soluble PFAS emissions remain below 1 gram per tonne of fluoropolymer treated. Municipal waste-to-energy (~22%) achieves comparable performance under routine operating conditions. - Recycling faces structural barriers
Recycling accounts for only approximately 3.4% of end-of-life fluoropolymers. While technically feasible for certain clean pre-consumer streams, post-consumer recycling is limited by extremely low material volumes, complex product integration, the absence of dedicated sorting infrastructure, and the lack of a viable secondary materials market in Europe. - Upstream benefits must be considered
Downstream users report that fluoropolymers extend component and system lifetimes by factors typically in the range of 3 to 10, depending on the application. Small fluoropolymer components such as seals and gaskets protect much larger systems, creating leverage effects on total waste generation well beyond the component’s own mass. Their impact must be assessed across the full lifecycle, not only at end of life.
Why this matters for Europe
Fluoropolymers are a negligible, highly dispersed waste stream that is effectively managed within existing systems and delivers upstream waste prevention benefits. Applying blanket restrictions to these materials would be technically unjustified, economically damaging, and disproportionate to the actual environmental risk.
The findings highlight the importance of:
What this means for EU chemicals regulation
Effective management at end-of-life, low waste contribution and upstream waste prevention, combined with the industry’s voluntary commitments for responsible manufacturing means that fluoropolymers do not constitute an unacceptable risk. Additionally, their overall contribution to strategic EU sectors and the lack of suitable alternatives means that a full exemption of fluoropolymers from any blanket restriction is the only justified regulatory approach.
Questions and Answers on the Fluoropolymers at their End-of-Life Study
The report provides a structured technical overview of how fluoropolymers are managed at their end-of-life, examining their occurrence in waste streams, treatment routes and overall emissions. It draws on a systematic literature review, full-scale incineration stack testing data from European and US facilities, and a value-chain stakeholder survey from across the fluoropolymer supply chain.
Fluoropolymers represent a very small fraction of total waste. The approximately 23,500 tonnes of fluoropolymer-containing waste collected in the EU in 2020 corresponds to less than 0.01% of total EU waste by mass.
Fluoropolymers are typically present as thin coatings, internal linings, cable insulation, membranes, seals or gaskets within much larger and more complex products. Because they represent only a small share of total product mass, separating them is usually technically difficult and economically unviable. In most cases they remain embedded in products through shredding, metal recovery or thermal treatment, which is why they are not collected as a distinct waste fraction.
Hazardous waste incineration is the dominant route, accounting for approximately 50% (~11.7 kt) of collected fluoropolymer waste. This reflects the primarily industrial origin of most fluoropolymer applications: at end of life, components such as seals, gaskets, liners and cables are typically classified as hazardous waste and managed accordingly. A further 22% (~5.15 kt) is directed to municipal waste-to-energy, covering consumer-origin streams and mixed residual fractions including automotive shredder residue and WEEE residues. Landfilling accounts for approximately 13% (~3.09 kt) and is expected to continue declining in line with EU waste policy. The remainder are dealt with through metal recycling (11.5%) and recycling (3.4%).
Both routes are highly effective. In hazardous waste incineration, fluoropolymers are destroyed at high temperatures. The report confirms destruction efficiencies reaching 99.9999%, with water-soluble PFAS emissions below 1 gram per tonne of fluoropolymer incinerated. Municipal waste-to-energy achieve comparable results in terms of destruction and emissions under routine operating conditions driven by the same underlying chemistry and similarly high combustion temperatures.
Landfilling represents a relatively small and declining share of fluoropolymer waste treatment (approximately 13%, ~3.09 kt in 2020) in line with EU waste policy that discourages landfilling. The chemical stability of fluoropolymers means they are unlikely to exceed fluoride leaching acceptance criteria in standard testing as shown in existing research. PFAS detected in landfill leachate cannot currently be attributed specifically to fluoropolymers rather than to non-polymeric PFAS or other fluorinated and non-fluorinated materials present in mixed waste.
Recycling is technically feasible for certain fluoropolymers, particularly clean, homogeneous pre-consumer production scrap of melt-processable fluoropolymers, and is already practised for these streams. However, post-consumer recycling is structurally limited by several factors: fluoropolymers account for less than 0.01% of total waste by weight; they are typically embedded in complex products that make separation technically difficult or uneconomical; sorting infrastructure and dedicated collection systems are largely absent; regulatory uncertainty around REACH compliance and the future end-of-waste status of recycled fluoropolymer content creates disincentives; and many high-performance applications require virgin-grade material, limiting the market for recyclates. There is currently no established secondary fluoropolymer material market in Europe.
No. Fluoropolymers vary significantly in their structure, processing, density, melting points and applications, and this has real consequences for what can be done with them at end of life. Some (such as FEP, PFA, ETFE and PVDF) can in principle be mechanically recycled when clean, separated streams exist. PTFE, despite being a thermoplastic, cannot be remelted in the conventional sense and requires specialised processing, typically resulting in material with significantly altered properties. Crosslinked fluoroelastomers such as FKM are fundamentally different again: they cannot be reprocessed by any conventional route.
Yes. Waste prevention sits at the top of the EU waste hierarchy, and the report examines fluoropolymers’ contribution to it. Stakeholder survey respondents report that fluoropolymers can extend component and system lifetimes by factors typically in the range of 3 to 10, depending on the application, operating environment, and the alternative material being compared. In many applications, small fluoropolymer components such as gaskets and seals protect much larger systems, creating leverage effects on total waste generation well beyond the component’s own mass.
Fluoropolymers are a negligible, highly dispersed waste stream that is effectively managed within existing systems, delivers significant upstream benefits, and behaves fundamentally differently from the PFAS of regulatory concern, both in use and at end of life. Treating them identically to other PFAS under a blanket restriction would be technically unjustified, economically damaging, and disproportionate to the actual environmental risk. The bottom line: fluoropolymers are not an unacceptable risk and should be fully exempted from any blanket restriction to ensure unintended consequences to European industry.
