Iterambere mu Ikoranabuhanga rya Green Solvent: Ibikoresho bibiri by'ibisubizo bishingiye ku binyabuzima n'ibizunguruka

1.Eastman yatangije "Umuti w'uruziga" wa Ethyl Acetate, yibanda kuri 30% by'ibicuruzwa bikomoka kuri Karuboni Ishobora Kuvugururwa bitarenze 2027

Ku ya 20 Ugushyingo 2025, Eastman Chemical yatangaje impinduka ikomeye mu ngamba: gushyira ubucuruzi bwayo ku isi bwa ethyl acetate mu ishami ryayo rya "Circular Solutions", yibanda ku guteza imbere icyitegererezo cyo gukora ibintu bikozwe mu buryo bufunze hakoreshejwe ethanol ishingiye ku binyabuzima nk'ibikoresho fatizo. Iyi sosiyete yashinze icyarimwe ibigo byo kugarura no kuvugurura ibintu bikomoka ku binyabutabire muri Amerika ya Ruguru no mu Burayi, igamije kubona ibirenga 30% by'ibikomoka kuri ethyl acetate mu bikomoka ku karubone ishobora kongera gukoreshwa bitarenze 2027. Ubu bushya bugabanya imyuka ihumanya ikirere iva mu gukora ibintu bikomoka ku binyabutabire ku kigero cya 42% mu gihe ikomeza gukoresha ibipimo by'imikorere bingana n'ibikomoka ku binyabutabire bisanzwe.

Iri terambere rijyanye n'ingamba zagutse z'inganda, nk'uko bigaragara mu bikorwa nk'umushinga wo kuvugurura ibiribwa bisukuye watangijwe ku bufatanye na PPG na SAIC General Motors, uteganya kugabanya imyuka ya CO₂ ho toni 430 buri mwaka. Ibikorwa nk'ibi bigaragaza impinduka mu rwego rw'ibinyabutabire, aho iterambere rirambye rigenda riterwa na moteri ebyiri z'ibikomoka ku bimera n'uburyo bugezweho bwo kuzenguruka. Mu gushyira imbere umutungo kamere ushobora kongera gukoreshwa no kongera gukoresha neza, ibi bishya ntibigabanya gusa ingaruka mbi ku bidukikije ahubwo binanongera imikorere myiza y'umutungo, bishyiraho igipimo gishya cy'inganda zibungabunga ibidukikije mu nganda. Guhuza ibikoresho bishingiye ku bimera n'uburyo bwo kuzenguruka bigaragaza uburyo buhuriweho bwo gukuraho karubone mu mikorere, bigategura inzira y'ejo hazaza h'inganda zirambye kandi zihamye.

2.PPG na SAIC-GM batangije ku mugaragaro umushinga wo kongera gukoresha ibikoresho bya solvent i Suzhou ku ya 1 Ukwakira 2025

Ku ya 1 Ukwakira 2025, umuyobozi w’ikigo gishinzwe gusiga irangi ry’imodoka PPG, ku bufatanye na SAIC General Motors, batangije ku mugaragaro gahunda y’ibanze yo kongera gukoresha irangi ry’ibinyabutabire i Suzhou. Uyu mushinga ushyiraho uburyo bwuzuye, bukubiyemo ubuzima bwose bw’ibinyabutabire: kuva mu gukora no gukoresha kugeza ku kuvugurura umutungo, kongera gukoresha no kongera gukoresha. Bakoresheje ikoranabuhanga rigezweho ryo gusya, iyi gahunda ikuramo neza ibice by’ibinyabutabire bifite isuku nyinshi mu binyabutabire.

Iyi gahunda yagenewe kugaruza toni zisaga 430 z'imyanda ihumanya ikirere buri mwaka, ikaba igera ku kigero gitangaje cya 80%. Iyi gahunda iteganijwe kugabanya imyuka ihumanya ikirere igera kuri toni 430 buri mwaka, bigabanyije cyane ingaruka z'ibikorwa byo gusiga imodoka. Mu guhindura imyanda mo umutungo kamere, ubufatanye bushyiraho igipimo gishya cy’ibidukikije ku nganda, bigaragaza uburyo ubukungu buzenguruka n’inganda zikora ibintu birambye.

3Abahanga mu bya siyansi b'Abashinwa bagezeho mu nganda ku rwego rwa Kilotoni mu gushonga amazi y'icyatsi kibisi ya Ionic ku gipimo cyo kugarura umusaruro ku kigero cya 99%

Ku ya 18 Kamena 2025, umushinga wa mbere ku isi wa “cellulose fibre” ukozwe mu mazi ya “ionic liquid” ukoresheje “kiloton” watangiye gukora i Xinxiang, Henan. Wakozwe n'itsinda ry'abashakashatsi riyobowe n'umuhanga mu by'ubumenyi Zhang Suojiang, ubu buryo bushya busimbura aside, alkali, na disulfide ya karubone ikoreshwa mu buryo bwa gakondo bwa viscose hamwe n'amazi ya “ionic” adahinduka kandi ahoraho. Ubu buryo bushya bugera kuri zero mu gusohora amazi mabi, imyuka mibi, n'imyanda ikomeye, mu gihe bufite igipimo cyo kugarura umwuka kirenga 99%. Buri toni y'ibicuruzwa igabanya imyuka ya karubone ihumanya ikirere ho toni zigera ku 5.000.

Iyi ntambwe imaze gukoreshwa mu nzego nko mu buvuzi no mu myenda, itanga inzira irambye yo guhindura ibidukikije mu nganda zikora fibre, ishyiraho uburyo bwo gukoresha ibinyabutabire mu buryo butangiza ibidukikije mu nganda.
