Muva nje, ukuthuthuka kwezobuchwepheshe kanye nokwandiswa kwamandla e-bio-based 1,4-butanediol (BDO) sekungenye yezindlela eziphawuleka kakhulu embonini yamakhemikhali yomhlaba wonke. I-BDO iwukhiye wezinto ezingavuthiwe zokukhiqiza ama-elastomer e-polyurethane (PU), i-Spandex, ne-PBT yepulasitiki engaboli, nenqubo yayo yokukhiqiza yendabuko encike kakhulu emafutheni ezinto ezimbiwa phansi. Namuhla, amabhizinisi ezobuchwepheshe amelwe yiQore, Geno, kanye ne-Anhui Huaheng Biology yasekhaya asebenzisa ubuchwepheshe obuthuthukisiwe bokuvutshelwa kwe-bio ukuze akhiqize ngobuningi be-BDO esekelwe ku-bio esebenzisa izinto ezingavuthiwe ezivuselelekayo ezifana noshukela nesitashi, okuhlinzeka ngenani elibalulekile lokunciphisa ikhabhoni ezimbonini ezisezansi nomfula.
Sithatha iphrojekthi yokubambisana njengesibonelo, isebenzisa izinhlobo ze-microbial ezinelungelo lobunikazi ukuguqula ngokuqondile ushukela wezitshalo ube yi-BDO. Uma kuqhathaniswa nomzila osuselwe ku-petroleum, i-carbon footprint yomkhiqizo ingancishiswa kufika ku-93%. Lobu buchwepheshe buzuze ukusebenza okuzinzile komthamo wesilinganiso esingamathani ayi-10 000 ngo-2023 futhi bathola ngempumelelo izivumelwano zokuthengwa kwempahla zesikhathi eside nama-multiple polyurethane giants e-China. Le mikhiqizo ye-BDO eluhlaza isetshenziselwa ukwenza izinto ezizinzile ezisekelwe ku-bio-based Spandex kanye ne-polyurethane izicathulo, ukuhlangabezana nesidingo esiphuthumayo sezinto ezithinta imvelo ezivela emikhakheni yokugcina efana ne-Nike ne-Adidas.
Ngomthelela wemakethe, i-BDO esekelwe ku-bio ayiyona nje indlela yobuchwepheshe eyengeziwe kodwa futhi iwukuthuthukiswa okuluhlaza kochungechunge lwezimboni ezivamile. Ngokwezibalo ezingaphelele, umthamo we-BDO omenyezelwe emhlabeni wonke futhi ongaphansi kokwakhiwa kwe-bio-based usudlule amathani angu-500,000 ngonyaka. Nakuba izindleko zayo zamanje ziphakeme kancane kunemikhiqizo esekelwe ku-petroleum, eqhutshwa izinqubomgomo ezifana ne-EU's Carbon Border Adjustment Mechanism (CBAM), inkokhelo eluhlaza yamukelwa abanikazi bemikhiqizo abengeziwe. Kuyaqapheleka ukuthi ngokukhishwa kwamandla okulandelanayo kwamabhizinisi amaningi, i-BDO esekelwe ku-bio izolungisa kabusha iphethini yokuhlinzeka nge-polyurethane ne-textile fiber ye-polyurethane ne-textile fiber phakathi neminyaka emithathu ezayo, isekelwa ukuthuthukiswa okuqhubekayo kokuncintisana kwezindleko zayo.
