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.
Izisebenzi ezifanele zaphawula ngalokhu okutholwe okusha: “Lolu bhubhane luye lwagqamisa indima ebalulekile edlalwa imishini yezokwelapha yepulasitiki elahlwayo ekuvimbeleni nasekulawuleni izifo zasesibhedlela.Umthelela ongemuhle wale mpumelelo ukwanda kwenani lemfucuza yasesibhedlela.Sikholelwa ukuthi ukugaywa kabusha kuyingxenye yesixazululo.Ngenhlanhla, ipulasitiki esetshenziswa kakhulu ekunakekelweni kwezempilo iphinde ibe yipulasitiki egaywa kabusha kakhulu, ngakho-ke sinxusa izibhedlela ukuthi ziqale ukusebenzisa i-PVC emisebenzini yokugaywa kabusha.”
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 izicelo, ezinye izinsimbi zePVC ziyatholakala futhi ziyasebenza.Ezine zazo manje sezifakwe ohlwini lwe-European Pharmacopoeia, okuwumkhiqizo wezokwelapha eYurophu nakwezinye izifunda.Kuthuthukiswe imihlahlandlela yokuphepha nekhwalithi.”
