PFAS—inowanzonzi “makemikari asingaperi”—iri pasi pekuongorora kusati kwamboitika pasi rose. Nemutemo weEU wePackaging and Packaging Waste Regulation (PPWR, 2025) unorambidza PFAS mukupakira chikafu kubva muna Nyamavhuvhu 2026, uye US EPA PFAS Action Plan (2021–2024) ichisimbisa miganhu mumaindasitiri, vagadziri veextrusions vari pasi pekumanikidzwa kutsiva fluoropolymer-based polymer processing aids (PPAs) nedzimwe nzira dzisina PFAS.

Sei zvichikosha kutikubvisa PFAS mu polymer extrusion?

Zvinhu zvinonzi Per- uye polyfluoroalkyl (PFAS), boka remakemikari anoramba achikanganisa endocrine, uye akabatana nekenza, chirwere chethyroid, uye matambudziko ekubereka. PFAS yave ichishandiswa mumaindasitiri nezvigadzirwa zvevatengi kubvira kuma1940. PFAS inowanikwa munzvimbo dzakasiyana-siyana nekuda kwechimiro chayo chemakemikari chakagadzikana. Sezvinonzi "makemikari asingaperi", anowanikwa muvhu, mumvura, nemhepo.8 Pamusoro pezvo, PFAS yakawanikwa muzvigadzirwa zvakasiyana-siyana (semuenzaniso, zvidziyo zvekubika zvisinganami, jira rinodzivirira mavara, furo rekudzimisa moto), chikafu, nemvura yekunwa, zvichiita kuti vanhu vakawanda vaonekwe (>95%).
Saka, kusvibiswa kwePFAS kwakaita kuti pave nemitemo yakaoma pakushandiswa kwayo mune zvinowedzera polymer extrusion. Kune vagadziri vemafirimu, mapaipi, uye tambo, maPPA echinyakare ane njodzi mukutevedzera mitemo uye mukurumbira wechiratidzo.

Pazasi pane shanduko dzemitemo chaiyo uye zvirongwa zvinobatsira pakuchinja uku, zvichibva paruzivo rwuripo:

1. Mabasa Ekutonga eEuropean Union (EU):

• Kurambidzwa kwePFAS kweECHA (2023): Muna Kukadzi 2023, European Chemicals Agency (ECHA) yakakurudzira kurambidzwa kwakazara kwezvinhu zveper- uye polyfluoroalkyl (PFAS) pasi pemutemo weREACH. Chirongwa ichi chakanangana nemhando dzakasiyana dzePFAS, kusanganisira fluoropolymers dzinoshandiswa sepolymer processing aids (PPAs). Kunyange hazvo indasitiri yefluoropolymer iri kutsvaga kusunungurwa, gwara remutemo rakajeka: zvirambidzo zviri kutungamirwa nekuramba kuripo kwezvakatipoteredza uye njodzi dzehutano dzinogona kuitika dzePFAS. Chinangwa ndechekuganhurira kugadzirwa, kushandiswa, uye kuiswa kwavo pamusika, nokudaro zvichiita kuti maindasitiri atore dzimwe nzira dzisina PFAS.

• Hurongwa hweEU hweMakemikoro eKuchengetedza Zvisimbiso: Hurongwa hweEU hunoshandisa nzira yakazara yekugadzirisa njodzi dzePFAS, huchiisa pamberi kubviswa kwezvinhu zvinokuvadza uye huchikurudzira kugadzirwa kwezvimwe zvinhu zvisina fluorine, kusanganisira izvo zvekugadzirisa polymer. Izvi zvakakurumidzisa hunyanzvi muPPAS-free PPAs, kunyanya kuve nechokwadi chekutevedzera mitemo yekubatana kwechikafu uye yekurongedza.

• European Union Packaging and Packaging Waste Regulation (PPWR) 2025: Yakaburitswa muEuropean Official Journal musi wa22 Ndira, 2025, PPWR inosanganisira kurambidzwa kushandiswa kwePFAS mumapakeji ekubatana nechikafu kutanga musi wa12 Nyamavhuvhu, 2026. Mutemo uyu une chinangwa chekuderedza kukanganisa kwezvakatipoteredza kwemapakeji nekuchengetedza hutano hwevanhu nekudzora PFAS muzvinhu zvekurongedza, kusanganisira zvinhu zvinobatsira pakugadzira polymer zvinoshandiswa mukubvisa purasitiki mumafirimu. Uyezve, PPWR inosimbisa zvinodiwa zvekudzokorodza - nzvimbo iyo maPPA asina PFAS anopa mukana wakajeka - nokudaro ichikurudzira kuchinja kune mhinduro dzemapakeji dzinogara kwenguva refu.

 2. Kuvandudzwa kweMitemo yeUnited States

• Chirongwa chePFAS cheEPA (2021–2024): Sangano reUS Environmental Protection Agency (EPA) rakaisa matanho akati wandei ekugadzirisa kusvibiswa kwePFAS:

• Kusarudzwa kwePFOA nePFOS sezvinhu zvine njodzi (Kubvumbi 2024): Pasi peMutemo weComprehensive Environmental Response, Compensation, and Liability Act (Superfund), EPA yakagadza perfluorooctanoic acid (PFOA) ne perfluorooctanesulfonic acid (PFOS)—makemikari makuru ePFAS anoshandiswa muPPAs—sezvinhu zvine njodzi. Izvi zvinowedzera pachena uye kuzvidavirira pakuchenesa uye zvinokurudzira maindasitiri kuti achinje kune dzimwe nzira dzisiri dzePFAS.

• Mutemo weNyika weMvura Yekunwa (Kubvumbi 2024): EPA yakapedzisa mutemo wekutanga wepamutemo wePFAS wemvura yekunwa, nechinangwa chekuderedza kusvibiswa kwevanhu vanosvika mamiriyoni zana. Mutemo uyu unomanikidza maindasitiri kubvisa PFAS kubva mumabasa ekugadzira, kusanganisira maPPA, kudzivirira kusvibiswa kwemvura.

• Kuwedzera kweZvinhu Zvinokonzera Toxics (TRI) (Ndira 2024): EPA yakawedzera PFAS nomwe kuTRI pasi peMutemo weNational Defense Authorization Act wa2020, zvichida kuti zvinyorwe mugore ra2024. Izvi zvinowedzera kuongororwa kwemaPPA ane PFAS uye zvinokurudzira kushandiswa kwezvimwe zvinhu zvisina PFAS.

• Zvikumbiro zveMutemo weKuchengetedza uye Kudzoreredza Zviwanikwa (RCRA) (Kukadzi 2024): EPA yakaronga mitemo yekuwedzera PFAS pfumbamwe pane runyorwa rwezvinhu zvine njodzi pasi peRCRA, zvichiwedzera simba rekuchenesa uye zvichiwedzera kukurudzira vagadziri kuti vawane mhinduro dzisina PFAS.

• Kurambidzwa Kwematunhu: Nyika dzakadai seMinnesota dzakaisa mitemo yekurambidza zvigadzirwa zvine PFAS, zvakaita semidziyo yekubikira, zvichiratidza kurwiswa kukuru kwezvinhu zvakagadzirwa nePFAS, kusanganisira maPPA anoshandiswa mukushandisa chikafu. Dzimwe nyika, kusanganisira California, Michigan, neOhio, dzakataura nezvekushaikwa kwedanho rehurumende senzira yekukonzeresa mitemo yePFAS yematunhu, zvichikurudzira kuchinja kuenda kumaPPA asina PFAS.

3. Zvirongwa zvePasirose neDunhu:

• Hurongwa hweCanada hweMutemo: Canada yakagadza mitemo yakasimba yekuderedza nekudzora kugadzirwa nekushandiswa kwePFAS, zvichikurudzira vagadziri vepasi rose kuti vatsive maPPAs ane chekuita nePFAS nesarudzo dzisina fluorine.

• Musangano weStockholm: Hurukuro yepasi rose pamusoro pemutemo wePFAS, kunyanya weperfluorooctanesulfonic acid (PFOS) nemamwe macompounds akafanana, yave ichienderera mberi kwemakore anopfuura gumi. Kunyange hazvo dzisiri nyika dzese (semuenzaniso, Brazil neChina) dzinorambidza zvizere mamwe maPFAS, maitiro epasi rose emutemo anotsigira kugamuchirwa kwePPAS-free PPAS PPAS.

• 3M's Phase-Out Commitment (2022): 3M, kambani huru inogadzira PFAS, yakazivisa kuti yaizomisa kugadzirwa kwePFAS panosvika kupera kwa2025, zvikaita kuti pave nekudiwa kukuru kwezvishandiso zvePFAS PPAs zvekutsiva zvinhu zvinobatsira zvinobva kufluoropolymer mumaindasitiri akaita semafirimu nemapombi ekubudisa.

4. Kutevedzera Mutemo weKubata Nezvekudya:

Mitemo inobva kuUS Food and Drug Administration (FDA) neEuropean Food Safety Authority (EFSA) inosimbisa maPPA asina PFAS ekushandisa pakubata chikafu.

5. Kumanikidzwa kwemusika neindasitiri

Kupfuura mitemo yepamutemo, kudiwa kwevatengi kwezvinhu zvisingakuvadzi nharaunda uye zvinangwa zvekuchengetedza makambani zviri kukurudzira varidzi vezvigadzirwa nevagadziri kuti vashandise maPPA asina PFAS. Izvi zvinonyanya kuoneka muindasitiri yekurongedza, uko mhinduro dzisina PFAS dzinotsvakwa dzekurongedza dzinochinjika, mafirimu akapfava, uye mafirimu evatambi kuti zvienderane nezvinodiwa pamusika uye kudzivirira kukuvara kwemukurumbira.

Mhinduro yeIndasitiri: MaPPAS-Free PPAS

Vatengesi vakuru vezvinhu zvinosanganisa polymer vakaita saSilike, Clariant, Baerlocher, Ampacet, naTosaf vakapindura nekugadzira maPPA asina PFAS anoenderana kana kupfuura mashandiro ezvinobatsira zvinobva kufluoropolymer. Izvi zvinobatsira kuderedza kupwanyika kwemvura, kuungana kwemvura, uye kumanikidzwa kwemvura, ukuwo vachiona kuti mitemo yekubatana nechikafu inotevedzwa uye vachitsigira zvinangwa zvekuchengetedza hupenyu.
