Munguva pfupi yapfuura, kubudirira kwetekinoroji uye kuwedzera simba kwebio-based 1,4-butanediol (BDO) yave imwe yeanonyanya kuzivikanwa maitiro muindasitiri yemakemikari yepasi rose. BDO chinhu kiyi mbishi yekugadzira polyurethane (PU) elastomers, Spandex, uye biodegradable plastic PBT, nemaitiro ayo echinyakare ekugadzira anoenderana zvakanyanya nemafuta ezvipfuyo. Nhasi, mabhizinesi etekinoroji anomiririrwa naQore, Geno, uye epamba Anhui Huaheng Biology ari kusimudzira tekinoroji yekuvirisa tekinoroji kugadzira yakawanda-yakavakirwa bio-BDO vachishandisa zvinogoneka kuita seshuga uye starch, zvichipa kukosha kwakakosha kudzikisa kabhoni kumaindasitiri epasi.
Tichitora chirongwa chekushandira pamwe semuenzaniso, chinoshandisa patented microbial strains kushandura zvakananga shuga yezvirimwa kuita BDO. Kuenzaniswa nepetroleum-yakavakirwa nzira, chigadzirwa kabhoni tsoka inogona kuderedzwa kusvika 93%. Iyi tekinoroji yakawana kushanda kwakagadzikana kwegumi zviuru-matani-chiyero muna 2023 uye yakabudirira kuchengetedza kwenguva yakareba zvibvumirano zvekutenga zvinhu nehofori dzakawanda dzepolyurethane muChina. Izvi zvigadzirwa zvakasvibirira zveBDO zvinoshandiswa kugadzira zvakagadzika bio-based Spandex uye polyurethane shangu zvinhu, zvichisangana nekukasira kudiwa kwezvinhu zvine hushamwari kwezvakatipoteredza kubva kumagumo mhando seNike neAdidas.
Panyaya yekukanganisa kwemusika, bio-based BDO haingori nzira yekuwedzera tekinoroji asiwo yakasvibira kukwidziridzwa kwechinyakare maindasitiri cheni. Zvinoenderana nehuwandu husina kukwana, huwandu hwepasirese hwakaziviswa uye pasi pekuvaka bio-based BDO huwandu hwakapfuura mazana mashanu ezviuru ematani pagore. Kunyangwe mutengo wazvino uno wakakwira zvishoma pane wezvigadzirwa zvepetroleum, zvichifambiswa nemitemo yakaita seEU's Carbon Border Adjustment Mechanism (CBAM), mari yegirinhi iri kutambirwa nevaridzi vemhando zhinji. Zviri kufanoona kuti nekuzoburitswa kwemabhizinesi akawanda kunotevera, bio-based BDO ichagadzirisa zvakanyanya 100-bhiriyoni-yuan yekugovera pateni ye polyurethane uye textile fiber mbishi mukati memakore matatu anotevera, ichitsigirwa neinoenderera mberi optimization yemakwikwi emutengo wayo.
