1.Eastman e Hlahisa "Tharollo e Selikalikoe" ea Ethyl Acetate, e shebaneng le 30% ea Sehlahisoa se Tsoang ho Khabone e Nchafalitsoeng ka 2027
Ka la 20 Pulungoana 2025, Eastman Chemical e phatlalalitse phetoho e kholo ea maano: ho kopanya khoebo ea eona ea lefats'e ea ethyl acetate karolong ea eona ea "Circular Solutions", e shebane le ho khothaletsa mohlala oa tlhahiso o koetsoeng o sebelisang ethanol e thehiloeng linthong tse phelang e le thepa e tala. Khamphani e thehile litsi tsa ho hlaphoheloa le ho tsosolosa li-solvent Amerika Leboea le Europe ka nako e le 'ngoe, e ikemiselitse ho fumana lihlahisoa tsa eona tsa ethyl acetate tse fetang 30% ho tsoa mehloling ea khabone e nchafatsoang ka 2027. Tlhahiso ena e ncha e fokotsa tlhahiso ea khabone e tsoang tlhahisong ea li-solvent ka 42% ha e ntse e boloka litekanyo tsa ts'ebetso tse lekanang le lihlahisoa tsa setso.
Nts'etsopele ena e tsamaellana le metsamao e pharaletseng ea indasteri, joalo ka ha ho bonoa mererong e kang projeke ea ho sebelisa hape solvent e hloekileng e qaliloeng ka kopanelo ke PPG le SAIC General Motors, e reretsoeng ho fokotsa mesi ea CO₂ ka lithane tse 430 selemo le selemo. Maiteko a joalo a totobatsa mokhoa oa phetoho lefapheng la lik'hemik'hale, moo botsitso bo ntseng bo eketseha ka lebaka la lienjine tse peli tsa lijo tse thehiloeng linthong tse phelang le litsamaiso tse chitja tse tsoetseng pele. Ka ho beha pele mehloli e nchafatsoang le ho sebelisoa hape ka katleho, boqapi bona ha bo fokotse tšusumetso ea tikoloho feela empa hape bo ntlafatsa katleho ea mehloli, bo beha tekanyetso e ncha bakeng sa tlhahiso e tala indastering. Ho kopana ha lintho tse kenang tse thehiloeng linthong tse phelang le mekhoa e chitja ho emela mokhoa o akaretsang oa ho tlosa khabone lits'ebetsong tsa tlhahiso, ho bula tsela bakeng sa bokamoso ba indasteri bo tsitsitseng le bo tiileng haholoanyane.
2.PPG le SAIC-GM li Qalile Semmuso Morero oa ho Sebelisa Solvent Recycling Suzhou ka la 1 Mphalane, 2025
Ka la 1 Mphalane, 2025, moetapele oa liphahlo tsa likoloi PPG, ka tšebelisano-'moho le SAIC General Motors, ba qalile semmuso lets'olo la pele la ho sebelisa hape li-solvent Suzhou. Morero ona o theha sistimi e felletseng, e koetsoeng e akaretsang potoloho eohle ea bophelo ba li-solvent: ho tloha tlhahisong le ts'ebelisong ho isa ho hlaphoheloeng ho reriloeng, ho nchafatsa mehloli le ho sebelisoa hape. Ka ho sebelisa theknoloji e tsoetseng pele ea ho qhibilihisa, ts'ebetso ena e ntša likarolo tse hloekileng haholo ho li-solvent tse litšila ka katleho.
Lenaneo lena le etselitsoe ho fumana lithane tse fetang 430 tsa li-solvent tsa litšila selemo le selemo, ho fihlella sekhahla se tsotehang sa tšebeliso ea hape sa 80%. Boiteko bona bo lebelletsoe ho fokotsa ho ntšoa ha carbon dioxide ka lithane tse ka bang 430 selemo se seng le se seng, ho fokotsa haholo tšusumetso ea tikoloho ea ts'ebetso ea ho koahela likoloi. Ka ho fetola litšila hore e be mehloli ea bohlokoa, tšebelisano-'moho e beha tekanyetso e ncha e tala bakeng sa indasteri, e bonts'a mohlala o ka atolosoang oa moruo o chitja le tlhahiso e tsitsitseng.
3Bo-rasaense ba Chaena ba fihletse ntlafatso ea indasteri ea boemo ba Kiloton ea li-solvents tsa metsi a Green Ionic ka sekhahla sa ho hlaphoheloa sa 99%
Ka la 18 Phuptjane 2025, projeke ea pele lefatšeng ea fiber ea cellulose e tsosolositsoeng ea ionic e thehiloeng holim'a mokelikeli oa kiloton e qalile ts'ebetso Xinxiang, Henan. E ntlafalitsoe ke sehlopha sa lipatlisiso se etelletsoeng pele ke Setsebi sa Thuto Zhang Suojiang, theknoloji ena e ncha e nkela sebaka li-acid tse senyang haholo, alkalis le carbon disulfide tse sebelisoang lits'ebetsong tsa setso tsa viscose ka li-ionic tse sa fetoheng le tse tsitsitseng. Sistimi e ncha e fihlella ho ntšoa ha metsi a litšila, khase e litšila le litšila tse tiileng ho tloha ho lefela, ha e ntse e ithorisa ka sekhahla sa ho hlaphoheloa ha solvent se fetang 99%. Tone ka 'ngoe ea sehlahisoa e fokotsa ho ntšoa ha carbon dioxide ka lithane tse ka bang 5,000.
E se e ntse e sebelisoa makaleng a kang tlhokomelo ea bophelo le masela, katleho ena e fana ka tsela e tsitsitseng bakeng sa phetoho e tala ea indasteri ea faeba ea lik'hemik'hale, e beha tekanyetso ea tšebeliso ea li-solvent tse mosa tikolohong tekanyong ea indasteri.
