Ngowama-2025, ishishini leekhemikhali lehlabathi lithatha amanyathelo abalulekileyo ekwamkeleni imigaqo-nkqubo yoqoqosho olujikelezayo, eqhutywa yimfuno yokunciphisa inkunkuma kunye nokugcina izixhobo. Olu tshintsho alupheleli nje ekuphenduleni uxinzelelo lolawulo kodwa lukwayindlela yobuchule yokuhambelana neemfuno ezikhulayo zabathengi zeemveliso ezizinzileyo.
Enye yezona zinto zibalulekileyo kukusetyenziswa kakhulu kwezinto ezisetyenzisiweyo kwimveliso yeekhemikhali. Iinkampani zityala imali kubuchwepheshe obuphambili bokusebenzisa kwakhona obuzivumela ukuba ziguqule inkunkuma emva komthengi ibe zizinto ezisemgangathweni ophezulu. Ukusetyenziswa kwakhona kweekhemikhali, ngakumbi, kuyanda njengoko kuvumela ukuqhekeka kweeplastiki ezintsonkothileyo zibe ziimonomers zazo zokuqala, ezinokuthi emva koko zisetyenziswe ukuvelisa iiplastiki ezintsha. Le ndlela inceda ukuvala umngxunya kwinkunkuma yeplastiki kwaye inciphise ukuxhomekeka kweshishini kumafutha angabonakaliyo.
Enye indlela ebalulekileyo kukwamkelwa kwe-bio-based feedstocks. Ezi feedstocks zifumaneka kwimithombo evuselelekayo efana nenkunkuma yezolimo, i-algae, kunye ne-oyile yezityalo, ezi feedstocks zisetyenziselwa ukuvelisa uluhlu olubanzi lweekhemikhali, ukusuka kwi-solvents ukuya kwi-polymers. Ukusetyenziswa kwezinto ezisekelwe kwi-bio-based akunciphisi nje kuphela i-carbon footprint yemveliso yeekhemikhali kodwa kukwabonelela ngenye indlela ezinzileyo kunee-petrochemicals zemveli.
Uqoqosho olujikelezayo lukwaqhuba ubuchule kuyilo lwemveliso. Iinkampani ziphuhlisa iikhemikhali kunye nezinto ezilula ukuziphinda zisetyenziswe kwaye zinomjikelo wobomi obude. Umzekelo, iintlobo ezintsha zeepolymers ezinokubola ziyayilwa ukuze ziqhekeke ngokufanelekileyo kwiindawo zendalo, zinciphise umngcipheko wongcoliseko. Ukongeza, imigaqo yoyilo lweemodyuli iyasetyenziswa kwiimveliso zeekhemikhali, okuvumela ukuba kube lula ukuziqhekeza nokuziphinda zisetyenziswe ekupheleni kobomi bazo obuluncedo.
Intsebenziswano ibalulekile kwimpumelelo yale mizamo. Iinkokheli zoshishino zenza ubudlelwane neenkampani zolawulo lwenkunkuma, ababoneleli ngetekhnoloji, kunye nabenzi bomgaqo-nkqubo ukuze kudalwe uqoqosho olujikelezayo oludibeneyo nolusebenzayo. Olu budlelwane lubalulekile ekwandiseni iziseko zokusetyenziswa kwakhona kwezinto, ukumisela iinkqubo ezisemgangathweni, kunye nokuqinisekisa ukuba kukho izinto ezisetyenzisiweyo ezisemgangathweni ophezulu.
Nangona kukho inkqubela phambili, imingeni isekho. Utshintsho oluya kuqoqosho olujikelezayo lufuna utyalo-mali olukhulu kubuchwepheshe obutsha kunye neziseko zophuhliso. Kukwakho nesidingo solwazi olukhulu lwabathengi kunye nokuthatha inxaxheba kwiinkqubo zokuphinda kusetyenziswe izinto ukuze kuqinisekiswe ukuba kukho ukuhanjiswa okuqhubekayo kwenkunkuma emva kokusetyenziswa kwezinto.
Ukuqukumbela, u-2025 ngunyaka otshintshayo kwishishini leekhemikhali njengoko lizamkela imigaqo yoqoqosho olujikelezayo. Ngokubeka phambili uzinzo kunye nokuvelisa izinto ezintsha, eli candelo alinciphisi nje kuphela impembelelo yalo kwindalo esingqongileyo kodwa likwadala namathuba amatsha okukhula kunye nokukhuphisana. Uhambo oluya kuqoqosho olujikelezayo luyinkimbinkimbi, kodwa ngentsebenziswano eqhubekayo kunye nokuzibophelela, ishishini leekhemikhali livula indlela yekamva elizinzileyo ngakumbi.
