Tsis ntev los no, thev naus laus zis thiab kev muaj peev xwm nthuav dav ntawm bio-based 1,4-butanediol (BDO) tau dhau los ua ib qho 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 yas PBT, nrog rau nws cov txheej txheem ntau lawm ib txwm nyob ntawm fossil fuels. Niaj hnub no, cov tuam txhab thev naus laus zis uas sawv cev los ntawm Qore, Geno, thiab hauv tebchaws Anhui Huaheng Biology tau siv cov thev naus laus zis bio-fermentation los tsim cov khoom siv bio-based BDO siv cov khoom siv txuas ntxiv dua tshiab xws li qab zib thiab cov hmoov txhuv nplej siab, muab cov pa roj carbon tsawg tsawg rau kev lag luam hauv qab.
Ua ib qho kev koom tes ua piv txwv, nws siv cov kab mob microbial patented ncaj qha hloov cov suab thaj cog rau hauv BDO. Piv nrog rau txoj kev siv roj av, cov khoom lag luam cov pa roj carbon hneev taw tuaj yeem txo tau txog li 93%. Cov thev naus laus zis no tau ua tiav kev lag luam ruaj khov ntawm 10,000-tuj-tej peev xwm hauv 2023 thiab ua tiav cov ntawv cog lus mus sij hawm ntev nrog ntau lub tuam txhab polyurethane loj hauv Suav teb. Cov khoom lag luam BDO ntsuab no yog siv los tsim cov khoom lag luam zoo li Spandex thiab polyurethane khau, ua kom tau raws li qhov xav tau sai rau cov khoom siv zoo ib puag ncig los ntawm cov khoom kawg xws li Nike thiab Adidas.
Nyob rau hauv cov nqe lus ntawm kev ua lag luam cuam tshuam, bio-based BDO tsis yog tsuas yog ib qho kev qhia ntxiv tab sis kuj yog ib qho kev hloov kho ntsuab ntawm cov khoom lag luam ib txwm muaj. Raws li kev txheeb cais tsis tiav, lub ntiaj teb tshaj tawm thiab kev tsim kho bio-based BDO muaj peev xwm tshaj 500,000 tons hauv ib xyoos. Txawm hais tias nws cov nqi tam sim no yog me ntsis siab dua li cov khoom siv roj av, tau tsav los ntawm cov cai xws li EU's Carbon Border Adjustment Mechanism (CBAM), tus nqi ntsuab tau txais los ntawm ntau thiab ntau tus tswv lag luam. Nws yog qhov pom tau tias nrog lub peev xwm tom qab tso tawm ntawm ntau lub lag luam, bio-based BDO yuav ua kom rov zoo dua 100-billion-yuan mov qauv ntawm polyurethane thiab textile fiber ntau raw cov ntaub ntawv nyob rau hauv peb lub xyoos tom ntej, txhawb nqa los ntawm kev ua kom zoo ntxiv ntawm nws cov nqi sib tw.
