Umthamo ophezulu kanye nokuphinda kusetshenziswe kabusha okuyingqayizivele kwe-PVC kubonisa ukuthi izibhedlela kufanele ziqale nge-PVC ngezinhlelo zepulasitiki zokugaywa kabusha kwemishini yezokwelapha. Cishe u-30% wemishini yezokwelapha yepulasitiki yenziwe nge-PVC, okwenza le nto ibe yi-polymer evame ukusetshenziswa kakhulu ekwenzeni izikhwama, amashubhu, imaski nezinye izinto zezokwelapha ezilahlwayo.
Isabelo esisele sihlukaniswe phakathi kwama-polymer angu-10 ahlukene. Lokhu ngokunye kokutholwe okuyinhloko ocwaningweni olusha lwemakethe olwenziwa ucwaningo lwemakethe yomhlaba wonke kanye nenkampani yokubonisana nabaphathi. Ucwaningo luphinde lubikezele ukuthi i-PVC izogcina isikhundla sayo sokuqala kuze kube okungenani u-2027.
I-PVC kulula ukuyigaya kabusha futhi inezinhlobonhlobo zokusetshenziswa. Izisetshenziswa ezidinga izingxenye ezithambile neziqinile zingenziwa ngokuphelele nge-polymer eyodwa-lokhu kuyisihluthulelo sempumelelo yokwenziwa kabusha kwepulasitiki. Umthamo ophezulu kanye nokuphinda kusetshenziswe kabusha okuyingqayizivele kwe-PVC kubonisa ukuthi izibhedlela kufanele ziqale ngale nto yepulasitiki lapho zicabangela izinhlelo zokugaywa kabusha kwemfucuza yepulasitiki yezokwelapha.
Abasebenzi abafanelekile baphawule ngokutholakele okusha: "Lo bhubhane luye lwagqamisa indima ebalulekile edlalwa yimishini yezokwelapha yepulasitiki elahlwayo ekuvimbeleni nasekulawuleni izifo zasesibhedlela. Umthelela omubi wale mpumelelo ukwanda kwenani lemfucumfucu yasesibhedlela. Sikholelwa ukuthi ukugaywa kabusha kuyingxenye yesixazululo. Ngenhlanhla, ipulasitiki esetshenziswa kakhulu ekunakekelweni kwezempilo iphinde ibe yipulasitiki egaywa kabusha kakhulu, ngakho-ke sinxusa imisebenzi ye-PVC ukuze isetshenziswe kabusha ezibhedlela. "
Kuze kube manje, ukuba khona kwezinto ze-CMR (carcinogenic, mutagenic, reproductive toxicity) emishinini ethile ye-PVC kube yisithiyo ekugayweni kabusha kwe-PVC yezokwelapha. Kuthiwa le nselele manje isixazululiwe: “Cishe kuzo zonke izinhlelo zokusebenza, ezinye izinsimbi zePVC ziyatholakala futhi ziyasebenza. Ezine zazo manje sezisohlwini lwe-European Pharmacopoeia, okuwumkhiqizo wezokwelapha eYurophu nakwezinye izifunda. Kwathuthukiswa iziqondiso zokuphepha nekhwalithi.”
