1.Ka Whakarewahia e Eastman te "Otinga Porowhita" o te Ethyl Acetate, me te Whai i te 30% o ngā Hua i Puta mai i te Waro Whakahou i te tau 2027
I te 20 o Noema, 2025, i panuitia e Eastman Chemical tētahi panoni rautaki nui: te whakauru i tana pakihi ethyl acetate o te ao ki roto i tana wehenga "Circular Solutions", me te arotahi ki te whakatairanga i tētahi tauira whakaputa porowhita kati e whakamahi ana i te ethanol e ahu mai ana i te koiora hei rauemi mata. I te wā kotahi, kua whakatūhia e te kamupene ngā pokapū whakaora me te whakahou whakarewa i Amerika Te Raki me Ūropi, me te whai kia neke atu i te 30% o ana hua ethyl acetate mai i ngā pūtake waro whakahou i te tau 2027. Ka whakaitihia e tēnei auahatanga ngā tukunga waro mai i te whakaputanga whakarewa mā te 42% me te pupuri tonu i ngā inenga mahi e rite ana ki ngā hua tuku iho.
E hangai ana tēnei whanaketanga ki ngā nekehanga whānui o te ahumahi, e kitea ana i roto i ngā kaupapa pēnei i te kaupapa hangarua whakarewa ma i whakarewahia ngātahitia e PPG me SAIC General Motors, e whakaritea ana kia whakaitihia ngā tukunga CO₂ mā te 430 tāne ia tau. Ko ēnei mahi e whakaatu ana i tētahi ia whakarerekētanga i roto i te rāngai matū, kei reira te pumau tonu e akiakihia ana e ngā miihini rua o ngā rauemi whāngai koiora me ngā pūnaha porowhita matatau. Mā te whakatairanga i ngā rauemi whakahou me te hangarua whai hua, kāore ēnei auahatanga e whakaiti noa i te pānga taiao engari ka whakarei ake i te whai huatanga o ngā rauemi, ka whakatakoto i tētahi paearu hou mō te hanga matomato i roto i te ahumahi. Ko te huihuinga o ngā whakaurunga koiora me ngā tikanga porowhita e tohu ana i tētahi huarahi whānui ki te tango waro i ngā tukanga whakaputa, e whakatakoto ana i te ara mō tētahi heke mai ahumahi pumau me te pakari ake.
2.Ka Whakarewa Mana a PPG me SAIC-GM i te Kaupapa Hangarua Whakarewa i Suzhou i te 1 o Oketopa, 2025
I te 1 o Oketopa, 2025, i whakarewahia mana e te kaiārahi o ngā paninga motuka, a PPG, me te mahi tahi me SAIC General Motors, tētahi kaupapa hangarua whakarewa matua i Suzhou. Ka whakatūhia e tēnei kaupapa he pūnaha whānui, he pūnaha kati-pōkai e kapi ana i te huringa ora katoa o ngā whakarewa: mai i te hanga me te tono ki te whakaora whai take, te whakaora rauemi, me te whakamahi anō. Mā te whakamahi i te hangarau whakatōtō matatau, ka tangohia pai e te tukanga ngā wāhanga parakore teitei mai i ngā whakarewa para.
Kua hangaia te kaupapa hei whakaora i te neke atu i te 430 tāne o ngā whakarewa para i ia tau, ā, ka eke ki te reiti whakamahinga anō whakamiharo o te 80%. E matapaetia ana ka whakaitihia e tēnei mahi ngā tukunga hauhā waro tata ki te 430 tāne i ia tau, ka tino whakaitihia te tapuwae taiao o ngā mahi paninga motuka. Mā te huri i ngā para hei rauemi whai hua, ka whakatakotohia e te mahi tahi he paearu matomato hou mō te umanga, e whakaatu ana i tētahi tauira tauine o te ōhanga porowhita me te hanga pumau.
3Kua tutuki i ngā Kairangataiao Hainamana te Ahumahi Taumata-Kirotoni o ngā Whakarewa Wai Kakariki Ionic me te 99% o te Reiti Whakaora
I te 18 o Hune, 2025, i tīmata te kaupapa muka cellulose whakaora-wai ionic taumata-kirotana tuatahi o te ao i Xinxiang, Henan. I whakawhanakehia e tētahi rōpū rangahau i arahina e te Kaiako Zhang Suojiang, ka whakakapia e tēnei hangarau auaha ngā waikawa tino waikura, ngā kawakore, me te waro disulfide e whakamahia ana i roto i ngā tukanga viscose tuku iho ki ngā wai ionic kore-pupuhi me te pumau. Ka tutuki i te pūnaha hou te tata ki te kore o te tukunga o te wai para, te hau para, me te para totoka, me te whakamanamana i te tere whakaora whakarewa neke atu i te 99%. Ia tana o te hua ka whakaiti i ngā tukunga waro hauhā tata ki te 5,000 tana.
Kua whakamahia kētia tēnei putanga hou i roto i ngā rāngai pēnei i te hauora me ngā kakahu, ā, ka whakaratohia he ara pumau mō te huringa matomato o te umanga muka matū, ka whakatakoto i te paearu mō te whakamahinga o te whakarewa e pai ana ki te taiao i runga i te tauine ahumahi.
