Search of PFAS-free alternatives in a wide range of sectors Challenge to find alternatives \ PFAS properties (oil repellence, biocompatibility, durability, chemical resistance...) \ PFAS enabling combination of properties

P \5
Barriers to the development of alternatives
ERDYN Confidential and proprietary information
Technical and knowledge barriers
Lower performance, safety concerns, skills gap for use.
Competing regulations imposing other demands
For example concerning global warming, EcoDesign, safety requirements.
Additional costs which can be prohibitive
CAPEX (installations, more complex products) or OPEX (operating costs).
Uncertainty as to which PFAS will be banned
When and for what applications; together with which alternatives will be brought in.
Concerns over sharing of innovation results
Potential market power of companies finding viable alternatives).
Lack of centralisation of information / coordination
Reduces flow of information as to potential solution and possible duplication of work.

3 maturity levels of PFAS substitution
Case A
ERDYN Confidential and proprietary information
Case A
increasing consumer / producer information on products containing (or not) PFAS
short term subsidisation to encourage users to switch system
ensuring the easy availability of technical information on the alternatives for users
ensuring that there is sufficient competent and trained staff to install and maintain these systems
place increasing restrictions on PFAS use by way of environmental permits (up until a full ban would be implemented)

3 maturity levels of PFAS substitution
Case B
ERDYN Confidential and proprietary information
Case B
Performance restrictions/limits
\ R&D can help R&D subsidies, information exchange and either/or collaborative R&D or optimising private incentives to innovate.
\ R&D cannot help subsidies to encourage switching to products with quality reduction or alternative products providing a similar function without PFAS
High CAPEX cost to switch
\ Related to purchase/installation costs subsidies that decrease over time
\ Related to R&D see performance restriction limits
High OPEX cost to run the alternative solution
Decreasing subsidies but trade-off with other public policies (e.g. R&D)

Use, properties and alternatives
ERDYN Confidential and proprietary information
PFAS used for:
- Personal protective equipment - Automotive textile used as seats covers - Construction materials
PFAS properties - water repellence - oil repellence - chemical and fire resistance - protection against infectious risk
No PFAS free alternative enabling
- Oil repellence
- The combination of properties listed above
-Washability (and therefore reusability)

Technical textiles
Barriers to PFAS substitution
ERDYN Confidential and proprietary information
Solution likely to come from companies developing chemicals for the textile industry (ongoing R&D for years/decades from demand for alternatives)
Several issues are likely to arise when the solution is found:
\ Price increases and foreclosure: potential market power following chemical company solution and patent protection (essential facility), so could :
Profitably raise prices; and/or
Selectively choose (or exclude) recipients of solution.
\ Bringing to market: Steps for technical textiles producers to be implemented (lab testing, certification and real-life testing)
In the short-term, no PFAS alternatives for personal protective equipment:
\ trade-off between environmental toxicity (PFAS) and the health of the people wearing PFAS-free personal protective equipment, having lower performance.
\ If a single use solution for PFAS were possible: trade-off between environmental toxicity (PFAS) and circular economy (linked to other environmental impacts).

Technical textiles - case C
Context and recommendations
ERDYN Confidential and proprietary information
No alternatives that allow sufficient oil repellence properties are currently available. Thus, there are different policy forms which may help
Short term
Assess the need for personal protective equipment in a public call for tenders; and
potentially adapt new requirements for certain uses (to reduce the need for PFAS in the short term)
Long term
Once an alternative is available from the chemicals industry subsidies for testing
organising a collaborative workshop to foster the development

Sector Batteries Case B
Cables Case B & C
Fire protection Case B
Key point on PFAS use in Belgium
- Approximatively 10 companies are likely to use PTFE and PVDF to produce materials and components of batteries in Belgium. - Debates about alternatives are only emerging and PFAS-free membranes, separators are under investigation.
Specific recommendation
- R&D subsidies, information exchange and either/or collaborative R&D or optimising private incentives to innovate.
- PFAS mainly consist in fluoropolymers, a volume of 40 t/y have been extrapolated for Belgium. - Different alternatives have already been tested (PEEK, PC, EPDM), with currently no technically feasible alternatives for all cables.
- R&D subsidies, information exchange and either/or collaborative R&D or optimising private incentives to innovate. - Provide subsidies that decrease over time to encourage substitution
- Fire suppressants & firefighting foams are a well-known stream of PFAS pollution, subject to specific regulation. - PFAS play a key role and the use of less performing chemistry leads to other environmental and health issues. - CO2, hydrocarbon, siloxanes are among the best alternatives, some of them are developped in Belgium
- R&D subsidies, information exchange and either/or collaborative R&D or optimising private incentives to innovate. - Provide subsidies that decrease over time to encourage substitution

Sector Metal processing Case B
Paints & Coatings Case A
Paper & Cardboard Case A
Key point on PFAS use in Belgium
- Industrials widely use 6:2FTS in hard chrome plating (1-2t/y) for the automotive, aeronautic or firearm markets. - Industrials are already facing challenge with the Cr(VI)-based process and seems unaware of the PFAS use. - Various strategies have been adopted for substituting PFAS: other chemistry, plating, process...
- According to IVP Coatings, PFAS-containing paints & coatings may represent up to 10% of the Belgian market (i.e., 200 million). - Industrial & transportation protective coatings are the main application of PFAS (FPs, 300t/y). - Epoxy, PU or silica-based coating already have high market share
- PFAS are not essential; and widely accepted alternatives already exist, no evidence and limit hint of PFAS use in Belgium have been found. - PFAS are mainly introduced via import, increased recycling leads to spreading PFAS throughout all the paper and board market.
ERDYN-RDC \ 07.12.2023 \ PFAS in Belgium - Final meeting
Specific recommendation - Focus on the development of alternatives that are both Cr(VI)-free and PFAS-free - Increase producer information levels - R&D subsidies
- Increase consumer information levels - Ensure technical guidance for substitution - Place increasing restriction on PFAS
- Gain knowledge on PFAS content of import product - Gain knowledge on PFAS incorporation during the end-of-life management

Sector Pesticides Case B
Plastics Case A & B
Semiconductors Case B
Developpement of alternatives
- Belgium is one of the largest consumers (7 kg/ha) and producers (10% of the EU industry) of pesticides in Europe, suggesting high PFAS use (529 t/y) - The subject of PFAS used as active substance in the manufacture of PPP is widely unknown in Europe & Belgium - There is very limited work on PFAS alternatives.
- Numerous PFAS-free polymerisation aids and polymer processing aids are already commercialized and used, none of them have been developed by Belgian actors. - FPs-free sealings appear to be extra-challenging: PEEK, PPS PPA, ACM or nitrile rubber do not fulfil all requirements, and would lead to higher leakage risk and maintenance cost.
Specific recommendation
- Increase consumer/producer information levels - Encourage overall reduction of PPP
Aids: place increasing restrictions on PFAS use
Focus the help on the downstream actors of the value chain (R&D & substitution subsidies)
- FPs and PFBS are used in highly diverse applications. However, the Belgian share of the EU industry only represent 1.5% (i.e., 66t/y PFAS used). - For a limited set of applications, HDPE, mineral oils or NF3, are potential alternatives. - Some companies do not share information on alternatives because of possible competition
