URhwebo oluKhawulezileyo lwe-BDO esekwe kwi-Bio luYima kwakhona i-100-yebhiliyoni-yeYuan ye-Polyurethane iMarike yeMpahla ekrwada.

Kutshanje, impumelelo yetekhnoloji kunye nokwandiswa kwamandla e-bio-based 1,4-butanediol (BDO) ibe yenye yezona ndlela zibalaseleyo kushishino lweekhemikhali zehlabathi. I-BDO sisixhobo esiphambili sokuvelisa i-polyurethane (PU) elastomers, i-Spandex, kunye ne-PBT yeplastiki ye-biodegradable, kunye nenkqubo yayo yemveli yokuvelisa ixhomekeke kakhulu kumafutha e-fossil. Namhlanje, amashishini etekhnoloji amelwe yiQore, iGeno, kunye ne-Anhui Huaheng Biology yasekhaya asebenzisa itekhnoloji ye-bio-fermentation ye-bio-fermentation ukuvelisa ngobuninzi be-BDO esekwe kwibhayoloji esebenzisa izinto ezinokusetyenziswa ngokutsha ezifana neswekile kunye nesitatshi, ebonelela ngexabiso elibalulekileyo lokunciphisa ikhabhoni kumashishini asezantsi.

Ukuthatha iprojekthi yentsebenziswano njengomzekelo, isebenzisa iintlobo zemicrobial ezinelungelo elilodwa lomenzi ukuguqula ngokuthe ngqo iiswekile zezityalo zibe yiBDO. Xa kuthelekiswa nendlela esekwe kwi-petroleum, indawo yekhabhoni yemveliso ingancitshiswa ukuya kuthi ga kwi-93%. Le teknoloji iphumelele ukusebenza okuzinzileyo komthamo we-10,000-toni-scale ngo-2023 kwaye yafumana ngempumelelo izivumelwano zokuthenga ixesha elide kunye ne-polyurethane giants ezininzi e-China. Ezi mveliso ze-BDO eziluhlaza zisetyenziselwa ukwenza i-Spandex esekelwe kwi-bio-based kunye nezixhobo ze-polyurethane izicathulo, ukuhlangabezana nemfuno engxamisekileyo yezinto eziphathekayo ezisingqongileyo ezivela kwiimpawu zokugqibela ezifana ne-Nike kunye ne-Adidas.

Ngokwempembelelo yentengiso, i-BDO esekwe kwibhayoloji ayiyondlela yobugcisa eyongezelelweyo kuphela kodwa ikwaluhlaziyo oluluhlaza lwekhonkco lemizi-mveliso yemveli. Ngokweenkcukacha-manani ezingagqitywanga, umthamo we-BDO obhengezwe kwihlabathi jikelele kunye nokwakhiwa ngaphantsi kolwakhiwo udlule kwiitoni ezingama-500,000 ngonyaka. Nangona ixabiso layo langoku liphezulu kancinane kuneemveliso ezisekwe kwipetroleum, eqhutywa yimigaqo-nkqubo efana ne-EU's Carbon Border Adjustment Mechanism (CBAM), ipremiyamu eluhlaza yamkelwa ngabanini bebrendi abangakumbi nangakumbi. Kuyabonwa ukuba ngokukhutshwa kwamandla okulandela amashishini amaninzi, i-BDO esekwe kwibhayoloji iya kubumba ngokutsha ipateni ye-100-bhiliyoni ye-yuan yobonelelo lwe-polyurethane kunye ne-textile fiber ekrwada kwisithuba seminyaka emithathu ezayo, exhaswa kukwandiswa ngokuqhubekayo kokhuphiswano lweendleko.
