Imishinga minini ya calcium karbide ya karubide PVC itanga umusaruro ushimangira ingamba ziterambere ryubukungu bwizunguruka, kwagura no gushimangira urwego rwinganda hamwe na calcium karbide PVC nkibyingenzi, kandi duharanira kubaka uruganda runini rwinganda ruhuza "amakara-amashanyarazi-umunyu". . Kugeza ubu, inkomoko y’ibicuruzwa bya vinyl mu Bushinwa biratera imbere mu buryo butandukanye, ari nabwo bwafunguye inzira nshya yo kugura ibikoresho fatizo ku nganda za PVC.Amakara yo mu ngo-kuri-olefine, methanol-kuri-olefine, Ethane-kuri-Ethylene nibindi bikorwa bigezweho byatumye itangwa rya Ethylene ryiyongera.
