Ocwaningweni lwakamuva olwenziwe abacwaningi abahamba phambili, kuye kwavela imiphumela eshaqisayo mayelana nokuphepha kwe-compostable.Kutholakale ukuthi lezi zitsha ezibonakala zivumelana nemvelo zingase zibe “namakhemikhali angunaphakade.”Lawa makhemikhali, aziwa ngokuthi yi-per- kanye ne-polyfluoroalkyl substances (PFAS), aveze ukukhathazeka ngenxa yemiphumela yawo emibi yezempilo engaba khona.

I-PFAS iyiqembu lamakhemikhali enziwe umuntu amelana nokushisa, amanzi, namafutha.Zisetshenziswe kakhulu ezimbonini ezihlukahlukene, kuhlanganise nokupakisha ukudla, ngenxa yekhono lazo lokuxosha amafutha noketshezi.Nokho, ucwaningo oluningana luye lwahlobanisa la makhemikhali nezinkinga ezihlukahlukene zezempilo, okuhlanganisa umdlavuza, izinkinga zokukhula, nokungasebenzi kahle kwamasosha omzimba.

Ucwaningo lwakamuva lugxile ekuhlanganiseni, ezimakethwa njengenye indlela eluhlaza kuneziqukathi zepulasitiki zendabuko.Lezi zitsha zenziwe ngephepha le-Kraft eligaywa kabusha futhi zifaka ulayini we-PE wangaphakathi ukuze uqine okwengeziwe.Ayaguquguquka, amelana nokuguqulwa, futhi afanele izinjongo eziningi.

Kodwa-ke, ucwaningo luthole iminonjana ye-PFAS enanini elibalulekile lezitsha zokukhipha umquba ezihloliwe.Lokhu okutholakele kuphakamisa ukukhathazeka mayelana nokufuduka okungenzeka kwalawa makhemikhali kusuka ezitsheni ukuya ekudleni akuqukethe.Abathengi bangase bavezwe ku-PFAS bengazi lapho bedla ukudla okunikezwa kulezi ziqukathi okuthiwa zilungele imvelo.

Yize kubalulekile ukuqaphela ukuthi amazinga e-PFAS atholakala ku-izitsha zephephaayephansi uma kuqhathaniswa, imiphumela yesikhathi eside yezempilo yokuchayeka okuqhubekayo ngisho namanani amancane alawa makhemikhali ayaziwa.Ngenxa yalokhu, ochwepheshe banxusa izinhlangano ezilawulayo ukuthi zibeke amazinga aqinile nemithethonqubo yokusebenzisa i-PFAS ezintweni zokupakisha ukudla.

Abakhiqizi beizitsha zokukhipha umqubabaphendule ngokushesha kulokhu okutholakele ngokuhlola kabusha izinqubo zabo zokukhiqiza nezinto zokwakha.Ezinye izinkampani sezivele zithathe izinyathelo ezibalulekile zokwehlisa amazinga e-PFAS emikhiqizweni yazo kanye nokuqinisekisa ukuphepha kwabathengi.

Ngenkathi ucwaningo luphakamisa ukukhathazeka ngobukhona be-PFAS ku-compostableizitsha zesaladi, kubalulekile ukukhumbula ukuthi lezi zitsha zisanikeza izinzuzo eziningi.Ukwakhiwa kwephepha labo le-Kraft eligaywa kabusha lizenza zibe ukukhetha okuvumelana nemvelo, futhi izakhiwo zazo ezivikela amanzi kanye nokumelana nowoyela zizenza zifanelekele izinhlobonhlobo zokudla.Kungakhathaliseki ukuthi amasaladi abandayo, i-poke, i-sushi, noma ezinye izibiliboco, lezi zitsha zinikeza inketho elula neguquguqukayo yokudla ohambeni.

Sengiphetha, okutholwe ocwaningweni lwakamuva kukhombisa ukuthi izitsha zokukhipha umquba zingaqukatha “amakhemikhali angunaphakade” aziwa nge-PFAS.Yize lokhu kutholwa kuphakamisa ukukhathazeka ngezingozi zezempilo ezingaba khona, abakhiqizi basebenza ngenkuthalo ukuze banciphise ukuba khona kwe-PFAS emikhiqizweni yabo.Naphezu kwalokhu okutholakele, i-compostablekraft paper isaladi izitshaukuqhubeka nokuba inketho ebalulekile kubantu abafuna izixazululo zokupakisha ukudla ezinobungani bemvelo nezilula.
