Kutshanje, impumelelo kwezobuchwepheshe kunye nokwandiswa kwamandla e-1,4-butanediol (BDO) esekelwe kwi-bio-based ibe yenye yezona ndlela ziphawulekayo kushishino lweekhemikhali lwehlabathi. I-BDO sisixhobo esibalulekileyo sokuvelisa ii-elastomers ze-polyurethane (PU), i-Spandex, kunye ne-PBT yeplastiki ebolayo, kwaye inkqubo yayo yemveli yemveliso ixhomekeke kakhulu kumafutha e-fossil. Namhlanje, amashishini etekhnoloji amelwe yi-Qore, i-Geno, kunye ne-Anhui Huaheng Biology yasekhaya asebenzisa itekhnoloji ye-bio-fermentation ephucukileyo ukuvelisa i-BDO esekelwe kwi-bio-based ngobuninzi besebenzisa izinto ezikrwada ezihlaziyekayo ezifana neswekile kunye nesitatshi, nto leyo ebonelela ngexabiso elikhulu lokunciphisa ikhabhoni kumashishini asezantsi.
Ukuthatha iprojekthi yentsebenziswano njengomzekelo, isebenzisa iintlobo zeentsholongwane ezinelungelo lobunikazi ukuguqula ngokuthe ngqo iiswekile zezityalo zibe yi-BDO. Xa kuthelekiswa nendlela esekwe kwi-petroleum, umlinganiselo wekhabhoni yemveliso ungancitshiswa ukuya kuthi ga kwi-93%. Le teknoloji ifikelele ekusebenzeni okuzinzileyo komthamo weetoni ezili-10,000 ngo-2023 kwaye yaqinisekisa ngempumelelo izivumelwano zokuthenga ixesha elide kunye neenkampani ezinkulu ze-polyurethane eTshayina. Ezi mveliso ze-BDO eziluhlaza zisetyenziselwa ukuvelisa izixhobo zeSpandex kunye nezihlangu ze-polyurethane ezisekelwe kwibhayoloji ezizinzileyo, ukuhlangabezana nemfuno engxamisekileyo yezinto ezinobuhlobo nokusingqongileyo ezivela kwiimpawu zokugqibela ezifana neNike kunye neAdidas.
Ngokuphathelele impembelelo yemarike, i-BDO esekelwe kwi-bio ayisiyondlela yobuchwephesha eyongezelelweyo kuphela kodwa ikwayindlela yokuphucula eluhlaza kwikhonkco lemizi-mveliso yendabuko. Ngokwezibalo ezingaphelelanga, umthamo we-BDO osekelwe kwi-bio obhengezwe kwihlabathi liphela nongakhiwanga udlule kwiitoni ezingama-500,000 ngonyaka. Nangona ixabiso layo langoku liphezulu kancinci kuneleemveliso ezisekelwe kwi-petroleum, eziqhutywa yimigaqo-nkqubo efana ne-EU's Carbon Border Adjustment Mechanism (CBAM), iprimiyamu eluhlaza iyamkelwa ngabanini beempawu abaninzi. Kuyabonakala ukuba ngokukhululwa komthamo okulandelayo kwamashishini amaninzi, i-BDO esekelwe kwi-bio iya kuyila ngokutsha kakhulu ipateni yokubonelela nge-polyurethane kunye ne-textile fiber materials ezixabisa i-100-billion-yuan kwiminyaka emithathu ezayo, ixhaswa kukuphuculwa okuqhubekayo kokhuphiswano lwayo lweendleko.
