Ngomhla ziyisi-9 kuMbasa, 2024, ososayensi baseShayina bashicilela indatshana ephephabhukwini I-Nature Chemistry mayelana nokugaywa kabusha kwezinto ezivuvukalayo ukuze kukhiqizwe uphethiloli wezinga eliphezulu, kuzuzwe ukusetshenziswa kahle kwe-waste polyethylene plastic.
Imfucumfucu yepulasitiki ibilokhu ingenye yezinselelo ezingathi sína ezibhekene nemvelo yomhlaba, futhi inani layo elikhulu lama-scaffolds liye ladala umonakalo omkhulu emvelweni. Kumapulasitiki angcolile, angashintshwa abe izikhwama zepulasitiki, amabhondi awo angewona amagama "carbon-carbon" anzima ukuwavula nokubhubhisa ngaphansi kwezimo eziphansi zokushisa. Lokhu okusha okutholwe ososayensi baseShayina kulethe ithemba lokuxazulula le nkinga.
Ngokusho kolwazi, lobu buchwepheshe bungakwazi ukuguqula kahle ipulasitiki yemfucuza ibe uphethiloli wekhwalithi ephezulu ngokusebenzisa uchungechunge lokusabela kwamakhemikhali okuyinkimbinkimbi futhi okuhle kakhulu. Lokhu akuhlinzeki nje ngemibono emisha yokwelashwa kwemfucuza yepulasitiki, kodwa futhi kuxazulula inkinga yokuntuleka kwamandla ezinhlelweni.
Ochwepheshe bathi lo mphumela kulindeleke ukuthi usetshenziswe ngezinga elikhulu esikhathini esizayo futhi ukhuthaze ukuthuthukiswa kwemboni yokubuyisela ipulasitiki. Uma ingakhuthazwa ngezinga elikhulu, ngeke nje inciphise ukungcoliswa kwemvelo okubangelwa udoti wepulasitiki, kodwa futhi idale inani elikhulu lezomnotho. Ngikholelwa ukuthi ngemizamo eqhubekayo yososayensi, sizobheka phambili ekusaseni elihlanzekile neliluhlaza.
