Njengoba ukukhathazeka kuye kwanda ngezingozi ezingaba khona zempilo nezemvelo ezihlobene nezinto ze-perfluoroalkyl kanye ne-polyfluoroalkyl (PFAS), kube nokushintshela ezitsheni zokusika umoba ezingenayo i-PFAS. Lesi sihloko sigxila ezizathwini zalolu shintsho, siqokomisa imiphumela yezempilo nemvelo ye-PFAS kanye nezinzuzo zokusebenzisa izitsha zokudla ezingenayo i-PFAS ezenziwe nge-pulp yomoba.
Ingozi ye-PFAS Izinto ze-perfluoroalkyl kanye ne-polyfluoroalkyl, ezivame ukubizwa ngokuthi i-PFAS, ziyiqembu lamakhemikhali okwenziwa asetshenziswa emikhiqizweni eyahlukahlukene yezimboni kanye neyabathengi ngenxa yokumelana kwawo nokushisa, amanzi, kanye namafutha.
Ngeshwa, lezi zinto aziqhekeki kalula futhi zivame ukuqongelela endaweni ezungezile nasemzimbeni womuntu. Izifundo eziningi zikhombisile ukuthi ukuchayeka kwi-PFAS kungaba nemiphumela emibi empilweni, okuhlanganisa umdlavuza wezinso kanye nowamasende, ukulimala kwesibindi, ukuncipha kokuzala, izinkinga zokukhula ezinsaneni nasezinganeni, kanye nokuphazamiseka kwamazinga ama-hormone.
La makhemikhali atholakale futhi ehlala emvelweni amashumi eminyaka, engcolisa amanzi nenhlabathi futhi ebeka usongo emvelweni.Izitsha Zokudlela ZomobaBeqaphela imiphumela eyingozi ye-PFAS, abathengi kanye nezimboni bafuna ezinye izindlela eziphephile. I-pulp yomoba, umkhiqizo ophuma enkambisweni yokukhiqiza ushukela, isibe yindlela engcono futhi enobungani nemvelo esikhundleni sezitsha zokudla zendabuko ezenziwe ngezinto ezifana nepulasitiki noma i-Styrofoam.
Izitsha zomumoba zenziwe nge-bagasse, insalela ye-fiber eseleyo ngemva kokukhishwa kwejusi lomoba. Iyabola, iyakwazi ukuvundiswa futhi ayidingi izinto eziluhlaza ukuze ikhiqizwe. Ngaphezu kwalokho, izitshalo zomoba zingatshalwa ngokushesha, zinikeze umthombo oqhubekayo novuselelekayo wezinto zokusetshenziswa.
Izinzuzo zokungabi ne-PFAS Esinye sezizathu eziyinhloko zokwanda kwesidingo semishini yokusika ujusi engena-PFAS ukugwema izingozi zempilo ezingaba khona. Abakhiqizi bayayeka ukusebenzisa i-PFAS ezinqubweni zabo zokukhiqiza ukuqinisekisa ukuthi imikhiqizo yabo iphephile futhi ayinamakhemikhali ayingozi. Abathengi baya ngokuya beqaphela isidingo sokunciphisa ukuchayeka kwabo ku-PFAS futhi bafuna ngenkuthalo ezinye izindlela ezingenayo i-PFAS.
Lesi sidingo sishukumisele abakhiqizi ukuthi bahlole kabusha imikhuba yabo futhi batshale imali kubuchwepheshe obungenazo i-PFAS, okuholele ekukhuleni kokutholakala kwalezi zinketho zokudla etafuleni eziphephile. Izinzuzo zemvelo Ngaphezu kwezinzuzo zezempilo,Ayinayo i-PFASizitsha ze-pulp kamobanazo zinezinzuzo ezinkulu zemvelo. Izitsha zokudla zepulasitiki ziletha inselele enkulu yokuphathwa kwemfucuza njengoba kuthatha amakhulu eminyaka ukubola futhi ngokuvamile zigcina zisezindaweni zokulahla imfucuza, olwandle noma ezindaweni zokushisa.
Ngokuphambene nalokho, izitsha zokusika ujusi womoba zipheleleiyabola futhi ikwazi ukubolaKusiza ekunciphiseni ingcindezi ezinhlelweni zokuphathwa kwemfucuza esezivele zicindezelekile futhi kunegalelo emnothweni ozinzile nozungezayo.
Ngokusebenzisa lezi zindlela ezingenayo i-PFAS, abathengi bangaba nomthelela omuhle emvelweni futhi baqhubekele phambili esikhathini esizayo esiluhlaza nesinomthwalo wemfanelo. Umthethonqubo kanye nesenzo semboni Beqaphela izingozi ezibangelwa yi-PFAS, abalawuli kwamanye amazwe bathatha izinyathelo zokunciphisa ukusetshenziswa kwala makhemikhali ayingozi.
Isibonelo, e-United States, i-Environmental Protection Agency (EPA) isungule izeluleko zezempilo ze-PFAS ethile emanzini okuphuza, futhi izifundazwe ngazinye zidlulisa umthetho wokuvimbela noma ukuvimbela ukusetshenziswa kwe-PFAS emaphaketheni okudla.
Njengoba imithethonqubo iba lukhuni, abakhiqizi bamukela ngenkuthalo imikhuba eqhubekayo futhi baphendukela kwezinye izindlela eziphephile. Inani elikhulayo lezinkampani manje lizibophezele ekukhiqizeni izitsha zomumoba ezingenayo i-PFAS, zivumelanise ukusebenza kwazo nesidingo sabathengi ngenkathi zihambisana nemithethonqubo eshintshayo.
Ekuphetheni Isidingo esikhulayo sezinto zokudla zikamoba ezingenayo i-PFAS sibonisa ukuqwashisa kwabathengi kanye nomthwalo wemfanelo wezemvelo. Ngokwamukela lezi zindlela ezinobungani nemvelo, abantu ngabanye kanye nezimboni bangafaka isandla eplanethini enempilo engenamiphumela elimazayo ye-PFAS. Njengoba imithetho ishintsha, lindela izinkampani eziningi ukuthi zamukele imikhuba engenayo i-PFAS, okuqhubekisela phambili ukushintshela ezinkethweni zokudla eziqhubekayo.
Ngokukhetha izitsha zomumoba ezingenayo i-PFAS, abantu ngabanye bangaba abahlanganyeli abakhuthele ekugcineni impilo, ukunciphisa imfucuza kanye nokwakha ikusasa elizinzile. Njengoba sibona lolu shintsho oluhle, kubalulekile ukuqhubeka nokusekela abakhiqizi kanye nabenzi bezinqubomgomo emizamweni yabo yokuhlinzeka ngezinketho eziphephile neziluhlaza.
