Kuphononongo olwenziwe kutshanje ngabaphandi abaphambili, kuye kwavela iziphumo ezoyikisayo malunga nokhuseleko lwe-compostisitya sesaladi yekraftKuye kwafunyaniswa ukuba ezi zitya zibonakala zinobuhlobo nokusingqongileyo zinokuba “neekhemikhali ezingapheliyo.” Ezi khemikhali, ezaziwa ngokuba zii-per- kunye ne-polyfluoroalkyl substances (PFAS), ziphakamise inkxalabo ngenxa yemiphumo yazo emibi kwimpilo.
I-PFAS liqela leekhemikhali ezenziwe ngumntu ezimelana nobushushu, amanzi, kunye neoyile. Ziye zasetyenziswa kakhulu kumashishini ahlukeneyo, kuquka ukupakishwa kokutya, ngenxa yokukwazi kwazo ukugxotha amafutha kunye nolwelo. Nangona kunjalo, izifundo ezininzi ziye zadibanisa ezi khemikhali kwimiba eyahlukeneyo yezempilo, kuquka umhlaza, iingxaki zophuhliso, kunye nokungasebenzi kakuhle kwenkqubo yomzimba yokuzikhusela.
Uphononongo lwakutshanje lugxile kwi-composableIsitya sesaladi esinesiciko, ezithengiswa njengendlela eluhlaza kunezikhongozeli zeplastiki zemveli. Ezi zitya zenziwe ngephepha leKraft eliphinda lisetyenziswe kwaye zinendawo yangaphakathi ene-PE ukuze zihlale ixesha elide. Ziyakwazi ukuguquguquka, ziyamelana nokuguquguquka, kwaye zifanelekile kwiinjongo ezahlukeneyo.
Nangona kunjalo, olu phononongo lufumanise imiqondiso yePFAS kwinani elikhulu lezitya zokukhupha umgquba ezivavanyiweyo. Olu phando luphakamisa inkxalabo malunga nokufuduka kwezi khemikhali zisuka kwizitya ziye ekutyeni ezikuyo. Abathengi basenokungayazi into yokuba bachaphazeleke yiPFAS xa besitya izitya ezikhonzwa kwezi zitya zinobuhlobo nokusingqongileyo.
Nangona kubalulekile ukuqaphela ukuba amanqanaba e-PFAS afunyenwe kwi-izitya zephephaNangona zaziphantsi kakhulu, iziphumo zempilo zexesha elide zokuchatshazelwa rhoqo zizixa ezincinci zezi khemikhali azikaziwa. Ngenxa yoko, iingcali zikhuthaza amaqumrhu alawulayo ukuba abeke imigangatho nemigaqo engqongqo yokusetyenziswa kwePFAS kwizixhobo zokupakisha ukutya.
Abavelisi beizitya zokutyela ezinomgqubabaye basabela ngokukhawuleza kwezi ziphumo ngokuphinda bahlole iinkqubo zabo zemveliso kunye nezixhobo. Ezinye iinkampani sele zithathe amanyathelo abalulekileyo ekunciphiseni amanqanaba e-PFAS kwiimveliso zazo nokuqinisekisa ukhuseleko lwabathengi.
Ngelixa uphando luphakamisa inkxalabo malunga nokuba khona kwe-PFAS kwi-compostizitya zesaladi, kubalulekile ukukhumbula ukuba ezi zitya zisabonelela ngeenzuzo ezininzi. Ukwakhiwa kwazo kwephepha leKraft eliphinda lisetyenziswe kuzenza zibe lukhetho olunobuhlobo nokusingqongileyo, kwaye iimpawu zazo ezingangeni manzi kwaye zingabi namafutha zizenza zifaneleke kwiintlobo ngeentlobo zokutya. Nokuba ziisaladi ezibandayo, ipoke, i-sushi, okanye ezinye izidlo ezimnandi, ezi zitya zibonelela ngokhetho olulula nolunokusetyenziswa ngeendlela ezahlukeneyo lokutya xa useluhambeni.
Ukuqukumbela, iziphumo zophando lwakutshanje zibonisa ukuba izitya zokukhupha umgquba zinokuqulatha "iikhemikhali ezingapheliyo" ezaziwa ngokuba yiPFAS. Nangona oku kufunyanisiweyo kuphakamisa iinkxalabo malunga neengozi zempilo ezinokubakho, abavelisi basebenza ngokukhutheleyo ukunciphisa ubukho bePFAS kwiimveliso zabo.Nangona ezi ziphumo zifunyenweyo, i-compostizitya zesaladi zephepha le-kraftiyaqhubeka nokuba yindlela exabisekileyo kubantu abafuna izisombululo zokupakisha ukutya ezinobuhlobo nokusingqongileyo nezilula.
