2027 Umbiko Wemakethe Yomhlaba Wonke Nge-Silica Yezinga Likasawoti: Isimo Sezidingo, Izibuyekezo Zemithetho Nezikhala Zokufaka Esikhundleni Sokungenisa

Imakethe yomhlaba wonke yosilika wezinga lokudla iyaqhubeka nokukhula, futhi isithako esivimbela ukunqwabelana kasawoti odliwayo siyisigaba esibalulekile sokusetshenziswa. Ngo-2027, imakethe yomhlaba wonke yosilika osetshenziselwa usawoti izoba namathrendi amathathu amakhulu: isidingo esihlukanisiwe, imithetho eqinile kanye nokuhlelwa kabusha kochungechunge lokuhlinzeka.

INyakatho Melika neYurophu zigcina umthamo wemakethe ozinzile. Isidingo sigxile kusawoti okhethekile, usawoti one-sodium ephansi kanye nosawoti onezinto ezinambitheka eziphilayo. Abathengi bafuna ukuhlanzeka okuphezulu nokungcola okuncane. Izinga eliphezulu lokuhlanzeka elihlangabezana namazinga e-USP ne-EP linamanani aphezulu. Izinkampani ezinkulu zendabuko ezihlanganisa i-Evonik ne-Cabot zigcina isabelo semakethe esisunguliwe ngenkathi zibhekene nengcindezi yezindleko eqhubekayo.

I-Asia Pacific iyisifunda esikhulu kunazo zonke emhlabeni ngokusetshenziswa. I-Latin America iletha ukukhula okuqinile okuholwa yi-Brazil, Mexico ne-Argentina. Njengoba izimboni zokucubungula usawoti zendawo zithuthuka futhi usawoti opakishiwe ungenelela ejulile, isidingo se-silica yokudla evumelana nemithetho futhi engabizi kakhulu siyaqhubeka nokukhuphuka.

Usawoti odliwayo uhlala uyisisekelo esiphambili se-silica yezinga likasawoti. Usawoti onezinongo oxutshiwe kanye nosawoti osebenza ngendlela ethile banezindlela eziyinkimbinkimbi kanye nokumunca umswakama okunamandla, okudinga i-silica enokusabalalisa okungcono kanye nokusebenza kokuvimbela ukunqwabelana. Lezi zigaba ezingavamile zikhula ngokushesha kunosawoti odliwayo ojwayelekile.

I-EFSA iyaqhubeka nokubuyekeza i-synthetic amorphous silica E551 futhi iqinisa ukulawulwa kokungcola. I-FDA kanye ne-Health Canada nabo babuyekeza izincazelo. Amazinga omhlaba aqinile akhuphula izithiyo zokungena futhi asusa amandla okukhiqiza asezingeni eliphansi angahambisani nemithetho.

Kuthinteka ngenxa yezombusazwe, ukuthutha olwandle kanye nokuguquguquka kwentela, abathengi bomhlaba wonke bahlukanisa izingozi zomhlinzeki. I-silica yaseShayina esezingeni lokudla, enekhwalithi ezinzile, izitifiketi ezigcwele kanye nentengo encintisanayo, ithatha indawo yemikhiqizo yaseYurophu naseMelika ethunyelwa ngaphandle futhi ingena emaketangweni okuhlinzeka ezinkampanini zokudla emhlabeni wonke.

I-silica yenjongo evamile ibhekene nokuncintisana okunzima. Ukuthuthukisa amazinga aqondene nezicelo ezithile kuba yinkomba ecacile: amazinga aphezulu okumunca uwoyela ezindaweni ezinomswakama, amazinga aphezulu okusabalalisa usawoti one-sodium ephansi, amazinga e-iron ephansi kakhulu kasawoti odliwayo osezingeni eliphezulu. Izithiyo zobuchwepheshe zemikhiqizo ekhethekile ziyaqhubeka zikhula.

Amathuba: Ukusetshenziswa kukasawoti odliwayo emhlabeni wonke kukhula ngokungaguquguquki. Isabelo esiphezulu sikasawoti opakishiwe nosawoti okhethekile siphakamisa isidingo se-silica. Izimboni zokudla ezimakethe ezisafufusa ziyakhula, zishiya indawo enkulu yokukhulisa ukungena kwezinto ezivimbela ukugwaduleka kukasawoti. I-silica yaseChina esezingeni eliphezulu iyaqhubeka nokuthola inzuzo yokushintsha okungeniswayo.

Izinselele: Izindleko zezinto zokusetshenziswa kanye namandla ziyashintshashintsha zicindezela inzuzo. Ukushintshashintsha kwezinga lokushintshisana kwemali kukhulisa izingozi zokuthumela ngaphandle. Imithetho yokudla yezizwe ehlukene inyusa izindleko zokuhambisana nemithetho.

Umthamo wemakethe uwonke we-silica yezinga likasawoti uzokhula ngokuqhubekayo ngo-2027 ngokuthuthukiswa kwesakhiwo somkhiqizo okusobala. Abahlinzeki kufanele bagxile ezingeni elikhethekile, baqedele izitifiketi zomhlaba wonke futhi bakhe izindlela zokubeka intengo zesikhathi eside eziguquguqukayo ukuze babambe amathuba. Abathengi bangahlukanisa isisekelo sabahlinzeki babo futhi bakhethe izinto zokusetshenziswa ezihambisana nomthetho, eziqinile ukuze kulinganiswe izinga kanye nezindleko zokuthenga.
