Muva nje, ukuthuthuka kwezobuchwepheshe kanye nokwandiswa kwamandla e-1,4-butanediol (BDO) esekelwe ku-bio-based kube ngenye yezindlela eziphawuleka kakhulu embonini yamakhemikhali yomhlaba wonke. I-BDO iyinto eluhlaza eyinhloko yokukhiqiza ama-elastomer e-polyurethane (PU), i-Spandex, kanye ne-PBT yepulasitiki ebolayo, kanti inqubo yayo yokukhiqiza yendabuko incike kakhulu kumafutha emvelo. Namuhla, amabhizinisi ezobuchwepheshe amelwe yi-Qore, i-Geno, kanye ne-Anhui Huaheng Biology yasekhaya asebenzisa ubuchwepheshe obuthuthukisiwe be-bio-fermentation ukukhiqiza i-BDO esekelwe ku-bio-based ngobuningi besebenzisa izinto zokusetshenziswa ezivuselelekayo njengoshukela kanye nesitashi, okunikeza inani elikhulu lokunciphisa ikhabhoni ezimbonini ezingezansi.
Uma sithatha iphrojekthi yokubambisana njengesibonelo, isebenzisa izinhlobo zamagciwane ezinelungelo lobunikazi ukuguqula ushukela wezitshalo ngqo ube yi-BDO. Uma kuqhathaniswa nomzila osuselwa kuphethiloli, umthelela wekhabhoni womkhiqizo ungancishiswa ngo-93%. Lobu buchwepheshe bufinyelele ekusebenzeni okuzinzile komthamo wamathani ayi-10,000 ngo-2023 futhi baqinisekisa ngempumelelo izivumelwano zokuthenga zesikhathi eside nezinkampani eziningi ezinkulu ze-polyurethane eShayina. Le mikhiqizo ye-BDO eluhlaza isetshenziselwa ukukhiqiza izinto ze-Spandex ezisekelwe ku-bio kanye nezicathulo ze-polyurethane ezisimeme kakhulu, okuhlangabezana nesidingo esiphuthumayo sezinto ezinobungani nemvelo ezivela kumabhrendi okugcina njenge-Nike ne-Adidas.
Ngokuphathelene nomthelela wemakethe, i-BDO esekelwe ku-bio ayiyona nje indlela yobuchwepheshe eyengeziwe kodwa futhi iwukuthuthukiswa okuluhlaza kochungechunge lwezimboni zendabuko. Ngokwezibalo ezingaphelele, umthamo we-BDO osekelwe ku-bio omenyezelwe emhlabeni wonke futhi ongakhiwanga usudlule amathani angu-500,000 ngonyaka. Nakuba izindleko zayo zamanje ziphakeme kancane kunezemikhiqizo esekelwe ku-petroleum, eziqhutshwa yizinqubomgomo ezifana ne-EU's Carbon Border Adjustment Mechanism (CBAM), iprimiyamu eluhlaza iyamukelwa ngabanikazi bemikhiqizo abaningi. Kusobala ukuthi ngokukhululwa kwamandla okulandelayo kwamabhizinisi amaningi, i-BDO esekelwe ku-bio izokwakha kabusha kakhulu iphethini yokuphakelwa kwe-polyurethane kanye nezinto zokusetshenziswa ze-fiber zendwangu ezingama-yuan ayizigidigidi eziyi-100 eminyakeni emithathu ezayo, kusekelwa ukwenziwa ngcono okuqhubekayo kokuncintisana kwayo ngezindleko.
