Tsis ntev los no, kev tshawb pom tshiab thiab kev nthuav dav ntawm bio-based 1,4-butanediol (BDO) tau dhau los ua ib qho ntawm cov qauv tseem ceeb tshaj plaws hauv kev lag luam tshuaj lom neeg thoob ntiaj teb. BDO yog cov khoom siv tseem ceeb rau kev tsim cov polyurethane (PU) elastomers, Spandex, thiab biodegradable plastic PBT, nrog nws cov txheej txheem tsim khoom ib txwm muaj nyob ntawm cov roj fossil. Niaj hnub no, cov tuam txhab thev naus laus zis sawv cev los ntawm Qore, Geno, thiab hauv tebchaws Anhui Huaheng Biology tab tom siv cov thev naus laus zis bio-fermentation siab heev los tsim cov bio-based BDO siv cov khoom siv rov ua dua tshiab xws li qab zib thiab hmoov txhuv nplej siab, muab cov nqi txo qis carbon rau cov lag luam downstream.
Piv txwv li, siv cov kab mob me me uas tau txais patent los hloov cov suab thaj ntawm cov nroj tsuag mus rau hauv BDO. Piv nrog rau txoj kev siv roj av, cov pa roj carbon ntawm cov khoom tuaj yeem txo tau txog li 93%. Cov thev naus laus zis no tau ua tiav kev ua haujlwm ruaj khov ntawm 10,000-tuj-qhov muaj peev xwm hauv xyoo 2023 thiab tau txais kev pom zoo ntev nrog ntau lub tuam txhab polyurethane loj hauv Suav teb. Cov khoom BDO ntsuab no yog siv los tsim cov khoom siv Spandex thiab khau polyurethane uas ruaj khov dua, ua tau raws li qhov xav tau ceev ceev rau cov khoom siv zoo rau ib puag ncig los ntawm cov hom lag luam kawg xws li Nike thiab Adidas.
Hais txog kev cuam tshuam ntawm kev ua lag luam, bio-based BDO tsis yog tsuas yog txoj kev siv tshuab ntxiv xwb tab sis kuj yog kev txhim kho ntsuab ntawm cov saw hlau kev lag luam ib txwm muaj. Raws li cov ntaub ntawv tsis tiav, lub ntiaj teb tshaj tawm thiab tab tom tsim bio-based BDO muaj peev xwm tshaj 500,000 tons ib xyoos. Txawm hais tias nws tus nqi tam sim no siab dua me ntsis ntawm cov khoom siv roj av, tsav los ntawm cov cai xws li EU's Carbon Border Adjustment Mechanism (CBAM), qhov hwm ntsuab tau txais los ntawm ntau thiab ntau tus tswv lag luam. Nws yog qhov kwv yees tau tias nrog rau kev tso tawm peev xwm tom qab ntawm ntau lub tuam txhab, bio-based BDO yuav rov ua dua tshiab 100-billion-yuan cov qauv muab khoom ntawm polyurethane thiab textile fiber raw cov ntaub ntawv hauv peb xyoos tom ntej, txhawb nqa los ntawm kev ua kom zoo dua ntawm nws cov nqi sib tw.
