Umthamo ophezulu kanye nokusebenziseka kabusha okuyingqayizivele kwe-PVC kubonisa ukuthi izibhedlela kufanele ziqale nge-PVC yezinhlelo zokusebenzisa kabusha amadivayisi ezokwelapha epulasitiki. Cishe ama-30% amadivayisi ezokwelapha epulasitiki enziwe nge-PVC, okwenza le nto ibe yi-polymer esetshenziswa kakhulu ekwenzeni izikhwama, amashubhu, imaski kanye namanye amadivayisi ezokwelapha alahlwayo.
Isabelo esisele sihlukaniswe phakathi kwama-polymer ayi-10 ahlukene. Lokhu kungenye yezinto eziyinhloko ezitholwe ocwaningweni olusha lwemakethe olwenziwe yinkampani yokubonisana ngocwaningo lwemakethe yomhlaba wonke kanye nokweluleka ngokuphathwa. Lolu cwaningo lubikezela nokuthi i-PVC izohlala isendaweni yayo yokuqala kuze kube okungenani ngo-2027.
I-PVC kulula ukuyiphinda isetshenziswe futhi inokusetshenziswa okubanzi. Imishini edinga izingxenye ezithambile neziqinile ingenziwa ngokuphelele nge-polymer eyodwa - lokhu kuyisihluthulelo sempumelelo yokuphinda isetshenziswe kwepulasitiki. Amandla aphezulu kanye nokuphinde isetshenziswe okuhlukile kwe-PVC kubonisa ukuthi izibhedlela kufanele ziqale ngalezi zinto zepulasitiki lapho zicabangela izinhlelo zokuphinda zisetshenziswe kwemfucuza yepulasitiki yezokwelapha.
Abasebenzi abafanele baphawule ngalokhu okutholakele okusha: “Lolu bhubhane lugqamise indima ebalulekile edlalwa amadivayisi ezokwelapha epulasitiki alahlwayo ekuvimbeleni nasekulawuleni ukutheleleka ezibhedlela. Umphumela omubi wale mpumelelo ukwanda kwenani lemfucuza yepulasitiki yasezibhedlela. Sikholelwa ukuthi ukuphinda kusetshenziswe kuyingxenye yesisombululo. Ngenhlanhla, ipulasitiki esetshenziswa kakhulu ekunakekelweni kwezempilo nayo iyipulasitiki ephinde isetshenziswe kakhulu, ngakho-ke sinxusa izibhedlela ukuthi ziqale ukusebenzisa i-PVC emisebenzini yokuphinda kusetshenziswe.”
Kuze kube manje, ukuba khona kwezinto ze-CMR (ezibangela umdlavuza, eziguqula i-mutagenic, kanye nobuthi bokuzala) emishinini ethile ye-PVC kube yisithiyo ekusetshenzisweni kabusha kwe-PVC yezokwelapha. Kuthiwa le nselele isixazululiwe manje: “Cishe kuzo zonke izinhlelo zokusebenza, ama-plasticizer ahlukile e-PVC ayatholakala futhi ayasebenza. Ezine zazo manje sezibhalwe ku-European Pharmacopoeia, okuwumkhiqizo wezokwelapha eYurophu nakwezinye izifunda. Kuthuthukiswe iziqondiso zokuphepha nekhwalithi.”
