Nō nā tata nei, ko ngā whanaketanga hangarau me te whakawhānui i te kaha o te 1,4-butanediol (BDO) e ahu mai ana i te koiora kua noho hei tetahi o ngā au tino rongonui i roto i te umanga matū o te ao. Ko te BDO he rauemi mata matua mō te whakaputa i ngā elastomers polyurethane (PU), Spandex, me te PBT kirihou pirau-koiora, me tana tukanga whakaputa tuku iho e tino whakawhirinaki ana ki ngā wahie pūmua. I ēnei rā, ko ngā umanga hangarau e tohuhia ana e Qore, Geno, me te Anhui Huaheng Biology o te rohe kei te whakamahi i te hangarau whakapūkara koiora matatau hei whakaputa papatipu i te BDO e ahu mai ana i te koiora mā te whakamahi i ngā rauemi mata whakahou pēnei i te huka me te māngaro, e whakarato ana i te uara whakaiti waro nui mō ngā ahumahi o raro.
Hei tauira, ka whakamahia e ia ngā momo moroiti kua patenttia hei huri tika i ngā huka tipu ki te BDO. Ki te whakatauritea ki te huarahi hinu, ka taea te whakaiti i te tapuwae waro o te hua tae atu ki te 93%. I tutuki i tēnei hangarau te mahi pumau o te kaha tauine 10,000-tana i te tau 2023, ā, i angitu te whiwhi whakaaetanga hoko wā roa me ngā kamupene polyurethane maha i Haina. Ka whakamahia ēnei hua BDO matomato hei hanga rauemi hu Spandex me te polyurethane e ahu mai ana i te koiora pumau ake, e tutuki ai te hiahia nui mō ngā rauemi hoa taiao mai i ngā waitohu mutunga pēnei i a Nike me Adidas.
Mō te pānga o te mākete, ehara i te mea he ara hangarau tāpiri noa te BDO e ahu mai ana i te koiora engari he whakapai ake i te mekameka ahumahi tuku iho. E ai ki ngā tatauranga kāore anō kia oti, kua neke atu i te 500,000 tāne ia tau te kaha o te BDO e ahu mai ana i te koiora kua panuitia, ā, kei te hangaia tonutia. Ahakoa he paku teitei ake te utu o nāianei i tērā o ngā hua e ahu mai ana i te hinu, nā ngā kaupapa here pēnei i te Tikanga Whakatikatika Rohe Waro a te EU (CBAM), kei te manakohia te utu matomato e te tini o ngā kaipupuri waitohu. E tika ana kia kitehia, mā te tukunga kaha o ngā umanga maha, ka huri hou te BDO e ahu mai ana i te koiora i te tauira tuku rauemi mata polyurethane me te muka kakahu 100 piriona yuan i roto i ngā tau e toru e whai ake nei, me te tautoko tonu i te arotautanga o tōna whakataetae utu.
