Ocwaningweni lwamuva olwenziwe abacwaningi abaphambili, kuye kwavela okutholakele okwethusayo mayelana nokuphepha kwe-compostisitsha sesaladi se-kraftKutholakale ukuthi lezi zitsha ezibonakala zinobungani nemvelo zingase zibe “namakhemikhali angunaphakade.” La makhemikhali, aziwa ngokuthi izinto ze-per- kanye ne-polyfluoroalkyl (PFAS), aphakamise ukukhathazeka ngenxa yemiphumela yazo emibi empilweni.
I-PFAS iyiqembu lamakhemikhali enziwe ngabantu amelana nokushisa, amanzi, kanye namafutha. Aye asetshenziswa kabanzi ezimbonini ezahlukene, okuhlanganisa nokupakisha ukudla, ngenxa yamandla awo okuxosha amafutha kanye noketshezi. Kodwa-ke, izifundo eziningana zixhumanise la makhemikhali nezinkinga ezahlukene zezempilo, okuhlanganisa umdlavuza, izinkinga zokukhula, kanye nokungasebenzi kahle kwesistimu yomzimba.
Ucwaningo lwakamuva lugxile ku-composableIsitsha sesaladi esinesembozo, ezithengiswa njengendlela eluhlaza esikhundleni sezitsha zepulasitiki zendabuko. Lezi zitsha zenziwe ngephepha le-Kraft eliphinde lisetshenziswe futhi zinengaphakathi elinomugqa we-PE ukuze ziqine kakhulu. Ziyakwazi ukuguquguquka, zimelana nokuguquguquka, futhi zifanelekela izinjongo eziningi.
Kodwa-ke, ucwaningo luthole iminonjana ye-PFAS ezitsheni eziningi zokuthatha izinto ezinomquba ezihlolwe. Lokhu kutholakele kuphakamisa ukukhathazeka mayelana nokufuduka okungenzeka kwala makhemikhali esuka ezitsheni aye ekudleni akuqukethe. Abathengi bangase bavezwe ngokungazi ku-PFAS lapho bedla ukudla okuphakelwa kulezi zitsha okuthiwa zinobungani nemvelo.
Nakuba kubalulekile ukuqaphela ukuthi amazinga e-PFAS atholakala ku-izitsha zephephaNakuba zaziphansi kakhulu, imiphumela yesikhathi eside yempilo yokuchayeka njalo ngisho nakwamanani amancane ala makhemikhali ayaziwa. Ngenxa yalokho, ochwepheshe banxusa izinhlangano ezilawulayo ukuthi zibeke amazinga nemithetho eqinile yokusetshenziswa kwe-PFAS ezintweni zokupakisha ukudla.
Abakhiqizi beizitsha zokuthatha ezifakwa umqubabaphendule ngokushesha kulezi ziphumo ngokuhlola kabusha izinqubo zabo zokukhiqiza nezinto zokwakha. Ezinye izinkampani sezivele zithathe izinyathelo ezibalulekile zokunciphisa amazinga e-PFAS emikhiqizweni yazo nokuqinisekisa ukuphepha kwabathengi.
Ngenkathi ucwaningo luphakamisa ukukhathazeka ngokuba khona kwe-PFAS ebhodweni elinomanyoloizitsha zesaladi, kubalulekile ukukhumbula ukuthi lezi zitsha zisanikeza izinzuzo eziningi. Ukwakhiwa kwazo kwephepha le-Kraft elingasetshenziswa kabusha kuzenza zibe ukukhetha okunobungani nemvelo, futhi izakhiwo zazo ezingangeni manzi futhi ezingamelani namafutha zizenza zifaneleke ekudleni okuhlukahlukene. Kungakhathaliseki ukuthi amasaladi abandayo, i-poke, i-sushi, noma ezinye izibiliboco, lezi zitsha zinikeza inketho elula neguquguqukayo yokudla ohambweni.
Ekuphetheni, okutholakele ocwaningweni lwakamuva kubonisa ukuthi izitsha zokuthatha izinto ezifakwa ebhodweni zingase zibe “namakhemikhali ahlala njalo” aziwa ngokuthi yi-PFAS. Nakuba lokhu okutholakele kuphakamisa ukukhathazeka ngezingozi ezingaba khona empilweni, abakhiqizi basebenza ngenkuthalo ukunciphisa ukuba khona kwe-PFAS emikhiqizweni yabo.Naphezu kwalokhu okutholakele, i-compostizitsha zesaladi zephepha le-kraftiyaqhubeka nokuba yindlela ewusizo kubantu abafuna izixazululo zokupakisha ukudla ezinobungani nemvelo futhi ezilula.
