Umbiko omusha we-IDTechEx ubikezela ukuthi ngo-2034, izitshalo ze-pyrolysis kanye ne-depolymerization zizocubungula amathani angaphezu kwezigidi ezingu-17 epulasitiki yemfucuza ngonyaka. Ukugaywa kabusha kwamakhemikhali kudlala indima ebalulekile ezinhlelweni zokugaywa kabusha kweziluphu ezivaliwe, kodwa kuyingxenye encane yesixazululo ezinseleleni zomhlaba jikelele zemvelo.
Nakuba ukugaywa kabusha komshini kudumile ngenxa yezindleko nokusebenza kahle kwakho, kodwa kuyawa ezinhlelweni ezidinga ukuhlanzeka okuphezulu nokusebenza kwemishini. Ukuze kubhekwane nezinselele ezibhekene nokugaywa kabusha kwamakhemikhali nokugaywa kabusha kwemishini, ubuchwepheshe bokuhlakazwa bubonise amandla amakhulu namathemba.
Inqubo yokuqedwa
Inqubo yokuhlakaza isebenzisa izincibilikisi ukuhlukanisa imfucuza ye-polymer. Lapho kusetshenziswa ingxube ye-solvent efanele, izinhlobo zepulasitiki ezihlukene zingancibilika ngokukhetha futhi zihlukaniswe, kube lula inqubo edinga ukuhlelwa kahle kwezinhlobo ze-polymer ngaphambi kokugaywa kabusha. Kukhona izincibilikisi ezenziwe ngokwezifiso nezindlela zokuhlukanisa zezinhlobo ezithile zepulasitiki, njenge-polypropylene, i-polystyrene, ne-acrylonitrile butadiene styrene.
Uma kuqhathaniswa nobunye ubuchwepheshe bokutholwa kwamakhemikhali, inzuzo enkulu yobuchwepheshe bokuhlakazwa ukuthi bungahlinzeka ngokusebenza okuphezulu kwethiyori.
Izinselelo ezikhona
Nakuba ubuchwepheshe bokuhlakazwa bunekusasa eliqhakazile, buphinde bubhekane nezinselelo ezithile nokungabaza. Umthelela wemvelo wezincibilikisi ezisetshenziswa ohlelweni lokuchithwa nawo uyinkinga. Ukuba nokwenzeka kwezomnotho kobuchwepheshe bokuhlakazwa nakho akuqiniseki. Izindleko zezincibilikisi, ukusetshenziswa kwamandla, kanye nesidingo sengqalasizinda eyinkimbinkimbi kungenza ama-polymer atholakale ngokusebenzisa izitshalo ezihlakazekayo abize kakhulu kunalezo ezitholwe ngomshini. Uma kuqhathaniswa nobunye ubuchwepheshe bokugaywa kabusha, kudinga ukutshalwa kwezimali okukhulu kanye nesikhathi.

Ikusasa Outlook
Njengobuchwepheshe obuthembisayo, ubuchwepheshe bokuncibilika bungahlangabezana nesidingo sekhabhoni ephansi kanye nezisombululo zepulasitiki zemfucuza ehlukahlukene. Kodwa-ke, ukwenziwa ngcono kwezobuchwepheshe, izinga lezentengiselwano kanye nezomnotho kuseyizinselelo okufanele zixazululwe. Ababambiqhaza badinga ukuhlola ngokucophelela okuhle nokubi kobuchwepheshe bokuchithwa ngaphakathi komongo wamasu omhlaba wokulawula udoti.
