I-PFAS - evame ukubizwa ngokuthi "amakhemikhali angunaphakade" - ingaphansi kokuhlolwa okungakaze kubonwe emhlabeni jikelele. Njengoba i-EU's Packaging and Packaging Waste Regulation (PPWR, 2025) ivimbela i-PFAS emaphaketheni othintana nokudla kusukela ngo-August 2026, kanye ne-US EPA PFAS Action Plan (2021–2024) eqinisa imikhawulo kuzo zonke izimboni, abakhiqizi be-extrusion bangaphansi kwengcindezi yokushintsha i-polypoly-based-PFAs-PFAs-based-fluoromer ezinye izindlela

Kungani kudingekilesusa i-PFAS ku-polymer extrusion?

I-Per- kanye ne-polyfluoroalkyl substances (PFAS), iqembu lamakhemikhali aphikelelayo aphazamisa i-endocrine, futhi axhumene nomdlavuza, isifo se-thyroid, nezinkinga zokuzala. I-PFAS isetshenziswe embonini nasemikhiqizweni yabathengi kusukela ngawo-1940s. I-PFAS ikhona yonke indawo emvelweni ngenxa yesakhiwo sayo samakhemikhali esizinzile. Njengoba okuthiwa “amakhemikhali angunaphakade”, atholwe enhlabathini, emanzini, nasemoyeni.8 Ukwengeza, i-PFAS itholakale emikhiqizweni ehlukahlukene (isb., i-cookware engagxili, indwangu engamelana namabala, amagwebu acisha umlilo), ukudla, namanzi okuphuza, okuholela ekuchayekeni cishe kwendawo yonke yabantu abaningi (> 95%).
Ngakho-ke, ukungcoliswa kwe-PFAS kuholele emithethweni eqinile ekusetshenzisweni kwazo ezithasiselweni ze-polymer extrusion. Kubakhiqizi befilimu, ipayipi, kanye nekhebula, ama-PPA endabuko adala ubungozi kukho kokubili ukuthobelana nesithunzi somkhiqizo.

Ngezansi izinguquko ezithile zokulawula kanye nezinyathelo ezifaka isandla kulolu shintsho, ngokusekelwe olwazini olutholakalayo:

1. Izenzo Zokulawula ze-European Union (EU):

• Umkhawulo Ohlongozwayo we-PFAS we-ECHA (2023): NgoFebhuwari 2023, i-European Chemicals Agency (ECHA) yenza isiphakamiso sokuthi kube nomkhawulo ophelele ku-per- kanye ne-polyfluoroalkyl substances (PFAS) ngaphansi komthethonqubo we-REACH. Lesi siphakamiso siqondise uhla olubanzi lwe-PFAS, okubandakanya ama-fluoropolymers asetshenziswa njenge-polymer processing aids (PPAs). Ngenkathi imboni ye-fluoropolymer ifuna ukukhululwa, isiqondiso sokulawula sicacile: imingcele iqhutshwa ukuphikelela kwemvelo kanye nezingozi zezempilo ezingaba khona ze-PFAS. Inhloso wukukhawulela ukwenziwa kwazo, ukusetshenziswa, kanye nokubekwa kwazo emakethe, ngaleyo ndlela kugqugquzele izimboni ukuthi zamukele ezinye izindlela ezingena-PFAS.

• Isu Lamakhemikhali E-EU Lokusimama: Isu le-EU lithatha indlela ephelele yokulawula ubungozi be-PFAS, libeka phambili ukukhishwa kwezinto eziyingozi futhi likhuthaze ukuthuthukiswa kwezinye izindlela ezingenayo i-fluorine, okuhlanganisa nalezo zokucubungula i-polymer. Lokhu kusheshise ukwakheka okusha kuma-PPA angenayo i-PFAS, ikakhulukazi ukuqinisekisa ukuhambisana nemithetho yokuxhumana nokudla kanye nokupakisha.

• I-European Union Packaging and Packaging Waste Regulation (PPWR) 2025: Ishicilelwe ku-European Official Journal ngomhla ka-Januwari 22, 2025, i-PPWR ihlanganisa ukuvinjelwa kokusetshenziswa kwe-PFAS emaphaketheni othintana nokudla kusukela ngo-Agasti 12, 2026. Umthetho uhlose ukwehlisa umthelela we-PFAS wokupakisha wemvelo ngokupakisha okusele kwe-PFAric izinto zokwakha, kufaka phakathi izinsiza zokucubungula i-polymer ezisetshenziswa ku-extrusion yefilimu yepulasitiki. Ngaphezu kwalokho, i-PPWR igcizelela izidingo zokuphinda zisetshenziswe kabusha—indawo lapho ama-PPA angenayo i-PFAS enikeza inzuzo ecacile—ngaleyo ndlela ekhuthaza ukushintshela ezixazululweni zokupakisha ezisimeme.

 2. Intuthuko Yokulawula Yase-United States

• I-EPA's Action Plan ye-PFAS (2021–2024): I-US Environmental Protection Agency (EPA) isebenzise izinyathelo ezimbalwa zokubhekana nokungcoliswa kwe-PFAS:

• Ukuqokwa kwe-PFOA ne-PFOS Njengezinto Eziyingozi (April 2024): Ngaphansi Komthetho Ophelele Wempendulo Yezemvelo, Isinxephezelo, Nesibopho (Superfund), i-EPA iqoke i-perfluorooctanoic acid (PFOA) kanye ne-perfluorooctanesulfonic acid (PFOS)—izinhlanganisela eziyisihluthulelo ze-PFAS ezisetshenziswa ezintweni eziyingozi—njenge-hazard. Lokhu kukhulisa ukubonakala kanye nokuziphendulela ekuhlanzeni futhi kukhuthaza izimboni ukuthi ziguqukele kwezinye izindlela ezingezona eze-PFAS.

• Izinga Likazwelonke Lamanzi Okuphuza (April 2024): I-EPA yaphothula izinga lokuqala lamanzi okuphuza eliphoqelelwa ngokomthetho le-PFAS, okuhloswe ngalo ukunciphisa ukuchayeka kubantu abangaba yizigidi eziyi-100. Lo mthethonqubo ucindezela izimboni ngokungaqondile ukuthi zisuse i-PFAS ezinqubweni zokukhiqiza, okuhlanganisa nama-PPA, ukuvimbela ukungcoliswa kwemithombo yamanzi.

• Izengezo ze-Toxics Release Inventory (TRI) (Januwari 2024): I-EPA yengeze i-PFAS eyisikhombisa ku-TRI ngaphansi koMthetho Wokugunyazwa Kwezokuvikela Kazwelonke wango-2020, odinga ukubika ngo-2024. Lokhu kukhulisa ukucutshungulwa kwama-PPA aqukethe i-PFAS futhi kugqugquzela ukutholwa kokunye okungenayo i-PFAS.

• Iziphakamiso Zomthetho Wokongiwa Kwensiza Nokubuyisela (i-RCRA) (Februwari 2024): I-EPA ihlongoze imithetho yokwengeza i-PFAS eyisishiyagalolunye ohlwini lwezindawo eziyingozi ezingaphansi kwe-RCRA, okuthuthukisa igunya lokuhlanza nokuqhubekisela phambili abakhiqizi ezixazululweni zamahhala ze-PFAS.

• Ukuvinjelwa Kwezinga Lesifunda: Amazwe afana ne-Minnesota asebenzise ukuvinjelwa kwemikhiqizo equkethe i-PFAS, efana ne-cookware, ebonisa ukwehliswa okubanzi kwezinto ezisekelwe ku-PFAS, okuhlanganisa nama-PPA asetshenziswa ezinhlelweni zokuxhumana nokudla. Ezinye izifundazwe, okubandakanya iCalifornia, Michigan, kanye ne-Ohio, ziveze ukushoda kwesenzo sobumbano njengomshayeli wemithetho ye-PFAS yezinga likahulumeni, okuqhubeka nokugqugquzela ukushintshela kuma-PPA angenayo i-PFAS.

3. Izinyathelo Zomhlaba Nezifunda:

• Uhlaka Lokulawula lwase-Canada: I-Canada isungule imithethonqubo eqinile yokunciphisa nokulawula ukukhiqizwa nokusetshenziswa kwe-PFAS, okuthonya abakhiqizi bomhlaba wonke ukuthi bamiselele ama-PPA asekelwe ku-PFAS ngezinye izindlela ezingenayo i-fluorine.

• I-Stockholm Convention: Ingxoxo yamazwe ngamazwe mayelana nomthetho we-PFAS, ikakhulukazi we-perfluorooctanesulfonic acid (PFOS) nezinhlanganisela ezihlobene nayo, ibilokhu iqhubeka isikhathi esingaphezu kweshumi leminyaka. Yize kungewona wonke amazwe (isb., iBrazil neChina) abeka imingcele ngokugcwele i-PFAS ethile, inkambiso yomhlaba wonke eya kumthetho isekela ukwamukelwa kwama-PPA angenawo ama-PFAS.

• I-3M's Phase-Out Commitment (2022): I-3M, umkhiqizi omkhulu we-PFAS, imemezele ukuthi izomisa ukukhiqizwa kwe-PFAS ekupheleni kuka-2025, okuholele ekukhuleni kwesidingo sama-PPA angewona awe-PFAS ukuthi athathele indawo izinsiza ezisekelwe ku-fluoropolymer ezimbonini ezifana nefilimu nokukhipha amapayipi.

4. Ukuthobela Ukuthintana Nokudla:

Imithetho evela ku-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) igcizelela ama-PPA angena-PFAS ezicelo zokuxhumana nokudla.

5. Ingcindezi Yezimakethe Nezimboni

Ngale kwemithetho elawulayo, isidingo sabathengi semikhiqizo eco-friendly kanye nezinhloso zokusimama kwebhizinisi kucindezela abanikazi bomkhiqizo nabakhiqizi ukuthi basebenzise ama-PPA angenayo i-PFAS. Lokhu kubonakala ikakhulukazi embonini yokupakisha, lapho kufunwa khona izixazululo zamahhala ze-PFAS zokupakishwa okuguquguqukayo, amafilimu ashaywayo, namafilimu asakazwayo ukuze ahlangabezane nokulindelwe yimakethe futhi agweme ukulimala kwesithunzi.

Impendulo Yemboni: Ama-PPA Amahhala e-PFAS

Abahlinzeki abakhulu bezengezo ze-polymer abafana no-Silike, Clariant, Baerlocher, Ampacet, kanye ne-Tosaf baphendule ngokwakha ama-PPA angenawo ama-PFAS afanayo noma adlule ukusebenza kwezinsiza ezisekelwe ku-fluoropolymer.
