Kupita Patsogolo kwa Ukadaulo Wosungunulira Zobiriwira: Zoyendetsa Ziwiri za Mayankho Ochokera ku Bio-Based ndi Ozungulira

1.Eastman Yayambitsa "Njira Yozungulira ya Ethyl Acetate," Yoyang'ana 30% ya Zinthu Zochokera ku Renewable Carbon pofika chaka cha 2027

Pa Novembala 20, 2025, Eastman Chemical idalengeza kusintha kwakukulu kwa njira: kuphatikiza bizinesi yake yapadziko lonse ya ethyl acetate mu gawo lake la "Circular Solutions", kuyang'ana kwambiri pakulimbikitsa njira yopangira yotsekedwa pogwiritsa ntchito ethanol yochokera ku bio ngati zopangira. Kampaniyo yakhazikitsa nthawi yomweyo malo obwezeretsa ndi kukonzanso zosungunulira ku North America ndi Europe, cholinga chake ndi kupeza zoposa 30% ya zinthu zake za ethyl acetate kuchokera kuzinthu zongowonjezwdwanso za kaboni pofika chaka cha 2027. Luso ili limachepetsa mpweya woipa wa kaboni kuchokera ku kupanga zosungunulira ndi 42% pomwe likusunga miyezo yogwira ntchito yofanana ndi zinthu zachikhalidwe.

Chitukukochi chikugwirizana ndi kayendetsedwe ka mafakitale ambiri, monga momwe zikuonekera m'mapulojekiti monga pulojekiti yokonzanso zinthu zosungunuka yoyera yomwe idayambitsidwa limodzi ndi PPG ndi SAIC General Motors, yomwe ikukonzekera kuchepetsa mpweya wa CO₂ ndi matani 430 pachaka. Ntchito zotere zikuwonetsa kusintha kwa gawo la mankhwala, komwe kukhazikika kumayendetsedwa kwambiri ndi injini ziwiri za zakudya zochokera ku bio-based ndi machitidwe apamwamba ozungulira. Mwa kuika patsogolo zinthu zongowonjezedwanso komanso kubwezeretsanso bwino, zatsopanozi sizimangochepetsa kuwononga chilengedwe komanso zimawonjezera kugwiritsa ntchito bwino zinthu, ndikukhazikitsa muyezo watsopano wopanga zinthu zobiriwira mumakampani. Kuphatikiza kwa zinthu zochokera ku bio-based ndi njira zozungulira kumayimira njira yonse yochotsera mpweya m'njira zopangira, ndikutsegulira njira tsogolo la mafakitale lokhazikika komanso lolimba.

2.PPG ndi SAIC-GM Ayambitsa Mwalamulo Pulojekiti Yobwezeretsanso Zosungunulira ku Suzhou pa Okutobala 1, 2025

Pa Okutobala 1, 2025, mtsogoleri wa PPG, mogwirizana ndi SAIC General Motors, adayambitsa mwalamulo ntchito yoyamba yobwezeretsanso zinthu zosungunulira ku Suzhou. Ntchitoyi ikukhazikitsa njira yokwanira, yozungulira yozungulira yomwe ikuphatikizapo moyo wonse wa zinthu zosungunulira: kuyambira kupanga ndi kugwiritsa ntchito mpaka kubwezeretsa zinthu, kukonzanso zinthu, ndikugwiritsanso ntchito. Pogwiritsa ntchito ukadaulo wapamwamba woyeretsera zinthu, njirayi imatulutsa bwino zinthu zoyera kwambiri kuchokera ku zinthu zosungunulira zinyalala.

Pulogalamuyi idapangidwa kuti ibwezeretse matani opitilira 430 a zinyalala chaka chilichonse, zomwe zimapangitsa kuti pakhale kuchuluka kodabwitsa kogwiritsanso ntchito kwa 80%. Kuyesetsa kumeneku kukuyembekezeka kuchepetsa kutulutsa kwa carbon dioxide ndi pafupifupi matani 430 chaka chilichonse, zomwe zimachepetsa kwambiri kuwonongeka kwa chilengedwe kwa ntchito zopaka utoto zamagalimoto. Mwa kusintha zinyalala kukhala zinthu zamtengo wapatali, mgwirizanowu ukukhazikitsa muyezo watsopano wobiriwira wamakampaniwa, kuwonetsa chitsanzo chokulirapo cha chuma chozungulira komanso kupanga zinthu zokhazikika.

3Asayansi aku China akwanitsa kupanga zinthu zosungunulira madzi za Green Ionic Liquid solvents pamlingo wa Kiloton ndi 99% Recovery Rate

Pa June 18, 2025, pulojekiti yoyamba padziko lonse ya ionic liquid-based cellulose fiber yopangidwanso ya kiloton inayamba kugwira ntchito ku Xinxiang, Henan. Yopangidwa ndi gulu lofufuza lotsogozedwa ndi Academician Zhang Suojiang, ukadaulo watsopanowu umalowa m'malo mwa ma acid, alkalis, ndi carbon disulfide omwe amagwiritsidwa ntchito kwambiri munjira zachikhalidwe za viscose ndi zakumwa za ionic zosasinthasintha komanso zokhazikika. Dongosolo latsopanoli limakwaniritsa kutulutsa madzi otayira, mpweya wotayira, ndi zinyalala zolimba pafupifupi zero, pomwe limadzitamandira ndi chiwongola dzanja chobwezeretsa solvent choposa 99%. Toni iliyonse ya chinthu imachepetsa kutulutsa kwa carbon dioxide ndi pafupifupi matani 5,000.

Popeza izi zagwiritsidwa kale ntchito m'magawo monga chisamaliro chaumoyo ndi nsalu, chitukukochi chimapereka njira yokhazikika yosinthira zachilengedwe m'makampani opanga ulusi wa mankhwala, ndikukhazikitsa muyezo wogwiritsira ntchito zosungunulira zachilengedwe pamlingo wa mafakitale.
