I-PFAS—edla ngokubizwa ngokuba “ziikhemikhali ezingunaphakade”—iphantsi koqwalaselo olungazange lubonwe ngaphambili kwihlabathi liphela. Njengoko i-EU's Packaging and Packaging Waste Regulation (PPWR, 2025) ithintela i-PFAS kwiipakethe zokutya eziqala ngo-Agasti 2026, kunye ne-US EPA PFAS Action Plan (2021–2024) iqinisa imida kumashishini, abavelisi be-extrusion baphantsi koxinzelelo lokutshintsha izixhobo zokulungisa i-polymer ezisekelwe kwi-fluoropolymer (PPAs) ngezinye iindlela ezingenayo i-PFAS.

Kutheni kuyimfunekosusa i-PFAS kwi-polymer extrusion?

Izinto ze-Per- kunye ne-polyfluoroalkyl (PFAS), iqela leekhemikhali eziphazamisa i-endocrine rhoqo, kwaye zidibene nomhlaza, isifo se-thyroid, kunye nemiba yokuzala. I-PFAS ibisetyenziswa kwimveliso zoshishino kunye nabathengi ukusukela ngeminyaka yoo-1940. I-PFAS ifumaneka kuyo yonke indawo ngenxa yesakhiwo sayo esizinzileyo seekhemikhali. Njengoko zibizwa ngokuba "ziikhemikhali ezingapheliyo", zifunyenwe emhlabeni, emanzini, nasemoyeni.8 Ukongeza, i-PFAS ifunyenwe kwiimveliso ezahlukeneyo (umz., izitya zokupheka ezinganamatheliyo, ilaphu elingangenisi amabala, amagwebu okucima umlilo), ukutya, kunye namanzi okusela, okukhokelela ekuvezweni phantse kuyo yonke indawo kuluntu ngokubanzi (>95%).
Ngoko ke, ungcoliseko lwePFAS lukhokelele kwimithetho engqongqo malunga nokusetyenziswa kwazo kwizithako ze-polymer extrusion. Kubavelisi beefilimu, iipayipi, kunye neentambo, ii-PPA zemveli zibeka umngcipheko ekuthobeleni imithetho kunye nodumo lwegama.

Apha ngezantsi kukho utshintsho oluthile lomthetho kunye namanyathelo anegalelo kolu tshintsho, ngokusekelwe kulwazi olufumanekayo:

1. Izenzo zoLawulo lweManyano yaseYurophu (i-EU):

• Uthintelo lwe-PFAS oluCetywayo lwe-ECHA (2023): NgoFebruwari 2023, i-European Chemicals Agency (ECHA) icebise uthintelo olupheleleyo kwizinto ze-per- kunye ne-polyfluoroalkyl (PFAS) phantsi komgaqo we-REACH. Esi siphakamiso sijolise kuluhlu olubanzi lwe-PFAS, kubandakanya ii-fluoropolymers ezisetyenziswa njengezixhobo zokulungisa iipolymer (PPAs). Ngelixa ishishini le-fluoropolymer lifuna ukukhululwa, ulwalathiso lolawulo lucacile: imiqathango iqhutywa kukungaguquguquki kwendalo kunye neengozi zempilo ezinokubakho ze-PFAS. Injongo kukunciphisa ukwenziwa kwazo, ukusetyenziswa kwazo, kunye nokubekwa kwazo kwimarike, ngaloo ndlela kukhokelela amashishini ukuba amkele ezinye iindlela ezingenayo i-PFAS.

• Icebo leeKhemikhali le-EU lokuZinza: Icebo le-EU lithatha indlela ebanzi yokulawula iingozi ze-PFAS, libeka phambili ukupheliswa kwezinto ezinobungozi kwaye likhuthaza uphuhliso lwezinye iindlela ezingena-fluorine, kuquka nezo zokucubungula i-polymer. Oku kukhawulezise ukwenziwa kwezinto ezintsha kwi-PPAs ezingena-PFAS, ngakumbi ukuqinisekisa ukuthotyelwa kwemigaqo yokunxibelelana kokutya kunye nokupakisha.

• Umgaqo-nkqubo we-European Union wokuPakisha nokuPakisha iNkunkuma (PPWR) ka-2025: Ipapashwe kwi-European Official Journal ngoJanuwari 22, 2025, i-PPWR ibandakanya ukuvinjelwa kokusetyenziswa kwe-PFAS ekupakisheni ukutya okunokunxibelelana nokutya ukususela nge-12 ka-Agasti 2026. Lo mgaqo-nkqubo ujonge ukunciphisa impembelelo yokusingqongileyo yokupakisha nokukhusela impilo yoluntu ngokuthintela i-PFAS kwizixhobo zokupakisha, kuquka nezixhobo zokucubungula i-polymer ezisetyenziswa ekukhupheni ifilimu yeplastiki. Ngaphezu koko, i-PPWR igxininisa iimfuno zokuphinda zisetyenziswe—indawo apho ii-PPA ezingenayo i-PFAS zibonelela ngenzuzo ecacileyo—ngaloo ndlela ikhuthaza ngakumbi ukutshintshela kwizisombululo zokupakisha ezizinzileyo.

 2. Uphuhliso lweMithetho ye-United States

• Isicwangciso se-EPA's PFAS Action Plan (2021–2024): I-US Environmental Protection Agency (EPA) isebenzise amanyathelo aliqela okujongana nongcoliseko lwe-PFAS:

• Ukutyunjwa kwe-PFOA kunye ne-PFOS njengeZinto eziyingozi (ngo-Epreli 2024): Phantsi koMthetho oPheleleyo wokuPhendula kwiNdalo, iMbuyekezo, kunye noXanduva (iSuperfund), i-EPA ityumbe i-perfluorooctanoic acid (PFOA) kunye ne-perfluorooctanesulfonic acid (PFOS)—iikhompawundi eziphambili ze-PFAS ezisetyenziswa kwi-PPAs—njengezinto eziyingozi. Oku kwandisa ukucaca kunye noxanduva lokucoca kwaye kukhuthaza amashishini ukuba atshintshele kwezinye iindlela ezingezizo ze-PFAS.

• Umgangatho weSizwe waManzi okuSela (ngo-Epreli 2024): I-EPA igqibezele umgangatho wokuqala wamanzi okusela osemthethweni we-PFAS, ujolise ekunciphiseni ukuvezwa kwabantu abamalunga nezigidi ezili-100. Lo mthetho ucinezela ngokungathanga ngqo amashishini ukuba asuse i-PFAS kwiinkqubo zokuvelisa, kuquka ii-PPA, ukuthintela ungcoliseko lwemithombo yamanzi.

• Izongezo zeToxics Release Inventory (TRI) (ngoJanuwari 2024): I-EPA yongeze ii-PFAS ezisixhenxe kwi-TRI phantsi koMthetho woGunyaziso loKhuselo lweSizwe ka-2020, nto leyo efuna ukuba kunikwe ingxelo ngo-2024. Oku kwandisa ukujongwa kwee-PPAs eziqulethe i-PFAS kwaye kukhuthaza ukwamkelwa kwezinye iindlela ezingenayo i-PFAS.

• Izindululo zoMthetho woLondolozo lweZixhobo kunye nokuBuyiselwa kweMithombo (RCRA) (ngoFebruwari 2024): I-EPA icebise imithetho yokongeza i-PFAS ezisithoba kuluhlu lwezinto ezinobungozi phantsi kwe-RCRA, ukuphucula igunya lokucoca kunye nokuqhubela phambili abavelisi kwizisombululo ezingenayo i-PFAS.

• Ukuvalwa Kwenqanaba Lelizwe: Amazwe afana neMinnesota aqalise ukuvalwa kweemveliso eziqulethe i-PFAS, ezifana nezitya zokupheka, nto leyo ebonisa ukugatywa okubanzi kwezixhobo ezisekelwe kwi-PFAS, kuquka ii-PPA ezisetyenziswa kwizicelo zokunxibelelana nokutya. Amanye amazwe, kuquka iCalifornia, iMichigan, kunye ne-Ohio, akhankanye ukungabikho kwesenzo sikarhulumente njengomqhubi wemithetho ye-PFAS yelizwe, nto leyo ekhuthaza ngakumbi ukutshintshela kwi-PPAs ezingenayo i-PFAS.

3. Amanyathelo eHlabathi kunye naweNgingqi:

• Isikhokelo soLawulo saseKhanada: IKhanada imisele imithetho eqinileyo yokunciphisa nokulawula imveliso nokusetyenziswa kwePFAS, nto leyo ephembelela abavelisi behlabathi ukuba bathathe indawo yeePPAs ezisekelwe kwiPFAS ngezinye iindlela ezingenafluorine.

• INgqungquthela yaseStockholm: Ingxoxo yamazwe ngamazwe malunga nomthetho we-PFAS, ngakumbi i-perfluorooctanesulfonic acid (PFOS) kunye neekhompawundi ezinxulumene nayo, ibiqhubeka kangangeminyaka engaphezu kweshumi. Nangona ingengawo onke amazwe (umz., iBrazil neTshayina) ayithinteli ngokupheleleyo i-PFAS ethile, indlela yehlabathi yokulawula ixhasa ukwamkelwa kwee-PPAs ezingenayo i-PFAS.

• I-3M's Phase-Out Commitment (2022): I-3M, umenzi omkhulu we-PFAS, ibhengeze ukuba iza kuyimisa imveliso ye-PFAS ekupheleni kuka-2025, nto leyo ebangele ukwanda kwemfuno yee-PPAs ezingezizo ze-PFAS zokuthatha indawo yezixhobo ezisekelwe kwi-fluoropolymer kumashishini afana neefilimu kunye ne-pipe extrusion.

4. Ukuthobela uNxibelelwano lokutya:

Imigaqo evela kwi-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA) igxininisa ii-PPA ezingenayo i-PFAS kwizicelo zokunxibelelana nokutya.

5. Uxinzelelo lweMarike kunye noShishino

Ngaphaya kwemiyalelo yomthetho, imfuno yabathengi yeemveliso ezinobuhlobo nokusingqongileyo kunye neenjongo zokuzinza kwenkampani zinyanzela abanini beemveliso kunye nabavelisi ukuba bamkele ii-PPAs ezingenayo i-PFAS. Oku kubonakala ngakumbi kushishino lokupakisha, apho izisombululo ezingenayo i-PFAS zifunwa khona kwiipakethe eziguquguqukayo, iifilimu ezitshatyalalisiweyo, kunye neefilimu zabadlali ukuze kuhlangatyezwane nolindelo lwemarike kwaye kuthintelwe umonakalo obangelwe ludumo.

Impendulo yoShishino: Ii-PPAs ezingenayo i-PFAS

Ababoneleli abakhulu bezongezo zepolymer ezifana neSilike, Clariant, Baerlocher, Ampacet, kunye neTosaf baphendule ngokuphuhlisa ii-PPAs ezingenayo i-PFAS ezihambelana okanye ezidlula ukusebenza kwezixhobo ezisekelwe kwi-fluoropolymer. Ezi ndlela zinceda ekunciphiseni ukwaphuka okunyibilikayo, ukwakheka kokufa, kunye noxinzelelo lwe-extrusion, ngelixa beqinisekisa ukuthotyelwa kwemigaqo yokunxibelelana kokutya kunye nokuxhasa iinjongo zozinzo.

Umzekelo,I-Silike SILIMER Series Polymer Extrusion Additives inikezela nge-PFAS-free, izisombululo ezingena-fluorineukoyisa imingeni yokucubungula. Yenzelwe iifilimu ezivuthuziweyo, ezifakwe kwi-cast, kunye nee-multilayer films, iifayibha, iintambo, iipayipi, i-masterbatch, i-compounding, kunye nokunye, inokuphucula ukusebenza kokucubungula uluhlu olubanzi lwee-polyolefins, kubandakanya kodwa kungaphelelanga kwi-mLLDPE, LLDPE, LDPE, HDPE, PP, kunye nee-polyolefins ezisetyenzisiweyo.
