Njengengxenye yokutshalwa kwezimali okuqhubekayo ekusungulweni kwezinto ezintsha okusimeme, i-Advance Denim yenza kube nokwenzeka ukukhiqiza okuhambisana nemvelo esikhungweni sayo esisha sokukhiqiza i-Advance Sico eNha Trang, eVietnam.
Njengoba iqediwe ngo-2020, lesi sitshalo sizokhonza izidingo zokukhiqiza ezikhulayo zomkhiqizi we-denim waseShayina ezimakethe ezintsha, okuzosiza ukuthi sikhonze amakhasimende amaningi.
Inhloso eyisisekelo ye-Advance Sico ifana nesikhungo sokuqala sokukhiqiza senkampani eShunde, eShayina. Umenzi akafuni nje ukunikeza amakhasimende akhe izitayela ze-denim ezintsha kakhulu eVietnam, kodwa futhi wabonisa izinto ezintsha eziqhubekayo ezibe yisisekelo sefektri iShunde.
Ngemva kokwakhiwa kwefektri yaseVietnam, umphathi jikelele we-Advance Denim, u-Amy Wang, wagxila kakhulu kuyo yonke inqubo yokukhiqiza i-denim ukuze abone ukuthi umenzi angathuthukisa kanjani ngezinqubo eziqhubekayo nezinobungani nemvelo. Yilokhu kugxila ekusimeni okunikeza indawo yezindlela ezintsha ezifana nokudaya i-Big Box, okusindisa amanzi afinyelela ku-95% asetshenziswa ekudayini kwendabuko lapho kusetshenziswa i-indigo yendabuko yoketshezi.
Lapho sekuqediwe, i-Advance Sico yaba yisitshalo sokuqala eVietnam ukusebenzisa i-indigo ka-Archroma engenayo i-aniline, ekhiqiza udayi we-indigo ohlanzekile nophephile ngaphandle kokusebenzisa amakhemikhali ayingozi abangela umdlavuza.
I-Advance Denim yabe isifaka i-BioBlue indigo ezinhlobonhlobo zayo zamadayi eVietnam, yakha i-indigo ehlanzekile engakhiqizi imfucuza enobuthi eyingozi emvelweni. I-BioBlue indigo idala nendawo yokusebenza ephephile ngokuqeda i-sodium hydrosulfite yamakhemikhali evuthayo futhi engazinzile endaweni yokusebenza.
Njengoba igama lisho, i-sodium dithionite inosawoti omningi kakhulu, okuyinto enzima kakhulu ukuyisusa emanzini angcolile. Into eyimpuphu ine-sulfates eningi futhi inganqwabelana emanzini angcolile, ikhiphe amagesi ayingozi. I-sodium dithionite ayigcini nje ngokuba yingozi emvelweni, kodwa iyinto engazinzile kakhulu, evuthayo eyingozi kakhulu ukuyithutha.
I-Advance Sico itholakala edolobheni lase-Nha Trang, indawo yokuvakasha yamazwe ngamazwe eyaziwa ngamabhishi ayo kanye nokuntywila emanzini. Lapho besebenzisa ifektri ye-Advance Sico lapho, abakhiqizi bazizwa benesibopho sokuvikela imvelo nokuba yifektri ehlanzekile nehlala isikhathi eside.
Ngalo moya, i-Advance Denim ifake uhlelo olusha lokuhlanza amanzi oluyi-reverse osmosis olwenzelwe ukususa ngempumelelo ukungcola okusele kanye nokulimazayo. Le nqubo ikhiqiza amanzi ahlanzekile cishe ngo-50% kunezindinganiso zezwe ze-chemical oxygen demand (COD). Iphinde ivumele lesi sikhungo ukuthi siphinde sisebenzise cishe amaphesenti angu-40 amanzi asetshenziswa enkambisweni yaso yokukhiqiza.
Njengoba bonke abakhiqizi be-denim kumele baqaphele, akuwona nje ubuciko obuqhuba ukusimama, kodwa yizinto zokusetshenziswa ngokwazo. Ifektri ye-Advance Sico isebenzisa izinto ezihlala isikhathi eside, okuhlanganisa ilineni elihle kanye nokotini ophinde wasetshenziswa kahle ovela eqoqweni lenkampani elihlala isikhathi eside le-Greenlet eVietnam.
“Siphinde sisebenze eduze nabasunguli bezinto zokuzinza emhlabeni jikelele abanjengoLenzing ukuze bafake izinhlobo zabo eziningi zemicu ye-round ne-zero carbon ezinhlotsheni zethu eziningi,” kusho uWang. “Siyaziqhenya hhayi nje ngokubambisana nabanye babasunguli bezinto zokuzinza emhlabeni, kodwa sikholelwa ukuthi kubalulekile ukuba nezitifiketi zokusekela izimangalo zethu. Lezi zitifiketi zibaluleke kakhulu kumakhasimende ethu njengoba i-Advance Sico yenza konke okusemandleni ayo Ukuze ibe ngumkhiqizi we-denim ozinzile kakhulu eVietnam.”
I-Advance Sico iqinisekiswe yi-Organic Content Standard (OCS), i-Global Recycling Standard (GRS), i-Recycling Claims Standard (RCS) kanye ne-Global Organic Textile Standard (GOTS).
I-Advance Denim izoqhubeka nokungabaza izindlela ezindala zokukhiqiza i-denim futhi isungule izindlela ezintsha zokukhiqiza ngendlela esimeme.
“Siyaziqhenya nge-Big Box denim kanye ne-BioBlue indigo kanye nendlela lezi zinto ezintsha ezidala ngayo inqubo yokudaya i-indigo ehlanzekile, ephephile futhi eqhubekayo ngaphandle kokulahla umthunzi nokugeza kwe-indigo yendabuko,” kusho uWang. “Siyajabula ukuletha lezi zinto ezintsha eziqhubekayo e-Advance Sico eVietnam ukuze zisondele kakhulu kumakhasimende ethu akhulayo esifundeni futhi zisebenze kangcono izidingo zamakhasimende ethu omhlaba.”
