Amashishini okuvelisa i-calcium carbide yasekhaya ye-PVC akhuthaza ngamandla isicwangciso sophuhliso loqoqosho lwesetyhula, akhulise kwaye aqinise ikhonkco lezoshishino kunye ne-calcium carbide ye-PVC njengengundoqo, kwaye azame ukwakha i-industrial cluster enkulu edibanisa "umbane wamalahle-ityuwa" Okwangoku, imithombo yemveliso yevinyl yevinyl eTshayina iphuhlisa kwicala elahlukileyo, eliye lavula nendlela entsha yokuthengwa kwemathiriyeli ekrwada kwishishini lePVC. I-Domestic coal-to-olefins, i-methanol-to-olefins, i-ethane-to-ethylene kunye nezinye iinkqubo zanamhlanje zenze ukunikezelwa kwe-ethylene kuninzi kakhulu.
