1.I-Eastman Yethula “Isixazululo Esiyindilinga” se-Ethyl Acetate, Ihlose U-30% Womkhiqizo Ovela Ku-Renewable Carbon ngo-2027
Ngomhlaka-20 Novemba 2025, i-Eastman Chemical yamemezela ushintsho olukhulu lweqhinga: ukuhlanganisa ibhizinisi layo lomhlaba wonke le-ethyl acetate esigabeni sayo se-"Circular Solutions", igxile ekukhuthazeni imodeli yokukhiqiza evaliwe kusetshenziswa i-ethanol esekelwe ku-bio njengezinto zokusetshenziswa. Le nkampani isungule izikhungo zokubuyisa nokuvuselela i-solvent eNyakatho Melika naseYurophu ngasikhathi sinye, ihlose ukuthola imikhiqizo yayo ye-ethyl acetate engaphezu kuka-30% emithonjeni yekhabhoni evuselelekayo ngo-2027. Lokhu kusungula kunciphisa ukukhishwa kwekhabhoni okuvela ekukhiqizweni kwe-solvent ngo-42% ngenkathi kugcinwa izilinganiso zokusebenza ezilingana nemikhiqizo yendabuko.
Lokhu kuthuthukiswa kuhambisana nokunyakaza okubanzi kwemboni, njengoba kubonakala ezinhlelweni ezifana nephrojekthi yokuvuselela kabusha i-solvent ehlanzekile eyethulwe ngokuhlanganyela yi-PPG kanye ne-SAIC General Motors, ehlelelwe ukunciphisa ukukhishwa kwe-CO₂ ngamathani angu-430 ngonyaka. Imizamo enjalo igcizelela umkhuba wokuguqula emkhakheni wamakhemikhali, lapho ukusimama kuqhutshwa khona kakhulu yizinjini ezimbili ze-feedstocks ezisekelwe ku-bio kanye nezinhlelo ezijikelezayo ezithuthukisiwe. Ngokubeka phambili izinsiza ezivuselelekayo kanye nokuvuselela kabusha okusebenzayo, lezi zinto ezintsha azigcini nje ngokunciphisa umthelela wemvelo kodwa futhi zithuthukisa ukusebenza kahle kwezinsiza, zibeka uphawu olusha lokukhiqiza okuluhlaza embonini. Ukuhlangana kokufakwayo okusekelwe ku-bio kanye nezindlela ezijikelezayo kumelela indlela ephelele yokususa i-carbon ezinqubweni zokukhiqiza, kuvuleke indlela yekusasa lezimboni elizinzile neliqinile.
2.I-PPG kanye ne-SAIC-GM Baqala Ngokusemthethweni iphrojekthi yokuvuselela i-solvent eSuzhou ngo-Okthoba 1, 2025
Ngomhlaka-1 Okthoba 2025, umholi we-PPG yezembozo zezimoto, ngokubambisana ne-SAIC General Motors, wethule ngokusemthethweni uhlelo lokuqala lokuvuselela izinyibilikisi eSuzhou. Lo msebenzi usungula uhlelo oluphelele, oluvaliwe oluhlanganisa umjikelezo wokuphila wezinyibilikisi: kusukela ekukhiqizweni nasekusetshenzisweni kuya ekubuyiselweni okuqondiwe, ukuvuselelwa kwezinsizakusebenza, kanye nokusetshenziswa kabusha. Isebenzisa ubuchwepheshe obuthuthukisiwe bokuhluza, le nqubo ikhipha ngempumelelo izingxenye ezihlanzekile kakhulu ezingxubeni zikadoti.
Lolu hlelo lwenzelwe ukubuyisa amathani angaphezu kuka-430 ezincibilikisi zemfucuza minyaka yonke, kufinyelelwe izinga lokusetshenziswa kabusha elihlaba umxhwele elingu-80%. Lo mzamo kulindeleke ukuthi unciphise ukukhishwa kwe-carbon dioxide cishe ngamathani angu-430 minyaka yonke, wehlise kakhulu umthelela wezemvelo wemisebenzi yokumboza izimoto. Ngokuguqula imfucuza ibe yimithombo ebalulekile, ukubambisana kubeka uphawu olusha oluluhlaza embonini, okubonisa imodeli ekwazi ukulinganiswa yomnotho ojikelezayo kanye nokukhiqiza okusimeme.
3Ososayensi baseShayina Bafinyelele Ukuthuthukiswa Kwezimboni Ezingeni Le-Kiloton Zezinyibilikisi Zoketshezi Eziluhlaza Ze-Ionic Ngezinga Lokubuyisa Elingu-99%
Ngomhlaka-18 Juni 2025, iphrojekthi yokuqala emhlabeni ye-ionic liquid-based cellulose fiber evuselelwe kabusha yezinga le-kiloton yaqala ukusebenza eXinxiang, eHenan. Yasungulwa yithimba locwaningo eliholwa yi-Academician uZhang Suojiang, lobu buchwepheshe obusha buthatha indawo yama-acid agqwalisayo kakhulu, ama-alkali, kanye ne-carbon disulfide asetshenziswa ezinqubweni zendabuko ze-viscose ngoketshezi lwe-ionic olungaguquguquki noluzinzile. Uhlelo olusha lufinyelela cishe ku-zero ukukhishwa kwamanzi amdaka, igesi engcolile, kanye nemfucuza eqinile, ngenkathi luqhosha ngesilinganiso sokubuyisa isinyibilikisi esingaphezu kuka-99%. Ithani ngalinye lomkhiqizo linciphisa ukukhishwa kwe-carbon dioxide cishe ngamathani angu-5,000.
Njengoba isivele isetshenziswa emikhakheni efana nokunakekelwa kwempilo kanye nezindwangu, le mpumelelo ihlinzeka ngendlela eqhubekayo yokuguqulwa okuluhlaza kwemboni yefayibha yamakhemikhali, ibeka uphawu lokusetshenziswa kwe-solvent enobungani nemvelo esikalini sezimboni.
