Unreacted TFE is recovered and reused in a continuous closed loop recycling process * TFE according to OECD PFAS definition is not a PFAS * Any accidental release of TFE leads to decomposition yielding carbonyl fluoride (COF2) that is further hydrolyzed in the presence of atmospheric water to form hydrogen fluoride (HF) and carbon dioxide (CO2)* * Recycling is also important for manufacturers to improve the production-cost efficiency Modifier (Perfluoropropylvinyl Ether, PPVE) * PTFE is modified to impart special properties - reduced deformation under load, improved flexibility, lower porosity, lower permeability, good electrical and mechanical properties and better processing * 25% of total commercially produced PTFE is chemically modified during polymerization; 0.05-0.1% of PPVE is incorporated in the PTFE polymer matrix; Approximately 1.5 times of PPVE is added to the reactor * PPVE requirements for PTFE: 0.25 * 25000 tons * 0.001 * 1.5 = 9.375 tons per annum * Around 70% is recovered for reuse and remaining is captured and destroyed using abatement * ECETOC JACC No. 42-Tetrafluoroethylene (CAS No. 116-14-3) 2966619 Case study -- PTFE emulsion polymerization As processing aids / surfactants * Fluorosurfactants (FS) do not get consumed during polymerization * Hundreds of tons of PFAS are intentionally used as polymerization aids leading to serious environmental pollution FS usage per ton = 3-10 kgs: For 25000 tons of fluoropolymers produced by emulsion polymerization: 75-250 tons * Manufacturing, Packaging, Storage and Transportation of FS are also contributing to PFAS emissions Raw materials to manufacture FS are also PFAS * FS break down to low temperature volatile PFAS that are difficult to abate * FS can be partially recovered and reused: GFL has been recycling 80-85 % of FS for reuse * Most fluoropolymers can now be produced without the use of FS * Fluoropolymers should be exempted; instead, regulate fluorinated polymerization aids 2966619 PTFE emulsion polymerization process chart Fluorinated Surfactant -- Mass balance in PTFE aqueous dispersion / Fine powder Upto 5% FS degrades at low temperature to --, other volatile PFAS Fluorinated Surfactant (Fs) 80-85% FS "ecoveoy Polymerization Reactor i 5-10% ESioss with spent IE 95% FS in Latex lon exchange (IE) + Ultrafiltration ((V]5] PTFE Dispersion Upto 0.1% FS in product Product 5-10% FS loss during recovery Coagulation Spent Carbon bed PTFE Fine powder Product Upto 0.1% FS in product 2966619 Development of Non-Fluorinated Polymerization Aid (NFPA) Gujarat Fluorochemicals: * GFL has developed NFPA technology to manufacture PTFE, PVDF, FKM, PFA * GFL commits to completely stop the intentional use of PFAS as polymerization aids from 2024* Solvay: * Working towards the objective of manufacturing nearly 100% of fluoropolymers without the use of fluorosurfactants in Spinetta Marengo, Italy by 2026** * Goal is to phase out the use of fluorosurfactants globally Arkema: * Voluntarily committed to manufacture its fluorinated polymers in Pierre-Bnite without the use of fluorosurfactants by the end of 2024, as well as its other production sites around the world*** Honeywell: * Voluntarily committed to completely stop using fluorosurfactants in their manufacturing processes * https://www.gfl.co.in/upload/pages/a6132d2292fc0ad3a9a0751dad818450.pdf ** https://www.solvay.com/en/innovation/science-solutions/pfas *** https://www.arkema.com/global/en/media/newslist/news/global/corporate/2023/20230221-arkema-position-on-european-proposal-to-restrict-pfas/ 2966619 Non-Fluorinated Polymerization Aid (NFPA) The NFPA used by GFL is an organic compound based on sulfonated hydrocarbon chemistry The specific NFPA substance is non-persistent, non-bioaccumulative, non-toxic and non-mobile It is EU REACH registered and is not listed under Substance of very High Concern (SvHC) and Toxic Release Inventory (TRI) NFPA based fluoropolymers exhibit equal or even better properties/specifications NFPA can be used to manufacture * High molecular weight fluoropolymers * Modified fluoropolymers * Copolymers and terpolymers A slight change in color may be noticed which is purely an aesthetic parameter and does not impact the performance 2966619 PFAS as byproducts using NFPA technology * Compatibility in terms of non-reactivity of hydrocarbon surfactants with monomers is critical to prevent formation of PFAS byproducts * EU has proposed PFAS concentration limits of 250 ppb as sum of targeted PFAS analysis * Fluoropolymers produced using GFL's NFPA have negligible PFASs measured using targeted analysis (LC-MS/MS) * There is no method or concentration limits defined for non-targeted PFAS analysis.
