Icyerekezo cya PVC, Icyerekezo cya Karubide PVC na Ethylene PVC

PVC ni ubwoko bwa pulasitiki ikoreshwa cyane mu bikoresho by'ubwubatsi. Kubwibyo, ntabwo izasimburwa igihe kirekire mu gihe kizaza, kandi izagira amahirwe menshi yo gukoreshwa mu turere tudateye imbere mu gihe kizaza.

Nkuko twese tubizi, hari uburyo bubiri bwo gukora PVC, bumwe ni uburyo mpuzamahanga bwa ethylene busanzwe, ubundi ni uburyo bwihariye bwa karubone ya calcium mu Bushinwa. Inkomoko y'uburyo bwa ethylene ahanini ni peteroli, mu gihe amasoko y'uburyo bwa karubone ya calcium ahanini ari amakara, limestone n'umunyu. Ubu butaka bwiganjemo cyane cyane mu Bushinwa. Kuva kera, uburyo bwa PVC bwa karubone ya calcium mu Bushinwa bwari ku mwanya wa mbere. Cyane cyane kuva mu 2008 kugeza 2014, ubushobozi bwa PVC mu Bushinwa bwo gukora karubone ya calcium bwagiye bwiyongera, ariko byanazanye ibibazo byinshi byo kurengera ibidukikije.

Ingufu zikoreshwa mu gukora karubone ya karubone ni nyinshi cyane, bityo ibi bizatera imbogamizi ku bukungu bw'ingufu mu Bushinwa. Kubera ko amashanyarazi aturuka mu gutwika amakara, agomba gukoresha amakara menshi, bityo gutwika amakara bizahumanya ikirere. Ariko, Ubushinwa bwagize impinduka zimwe na zimwe muri politiki mu myaka yashize. Ubushinwa burimo kuvugurura uruhererekane rw'inganda. Ubu turabona ko Ubushinwa bwatumije peteroli nyinshi mu mahanga, kandi ibigo by'ibanze birashishikarizwa gutumiza peteroli mu mahanga kugira ngo binoze ibicuruzwa biri hasi. Kubwibyo, mu myaka ya vuba aha, inganda nyinshi nshya zikora ethylene zongewe mu Bushinwa, kandi ubushobozi bushya bwose bwa PVC mu Bushinwa mu myaka ya vuba aha ni ubushobozi bwo gukora ethylene. Ubushobozi bwo gukora uburyo bwa karubone ya karubone mu Bushinwa bwahagaritse kwemezwa gushya. Kubwibyo, mu gihe cya vuba aha, umubare w'inganda za ethylene mu Bushinwa uzakomeza kwiyongera kandi uburyo bwa karubone ya karubone buzakomeza kugabanuka. Mu gihe kizaza, ingano y'uburyo bwa ethylene bwoherezwa mu mahanga mu Bushinwa buzakomeza kwiyongera, kandi buhoro buhoro bube ubwa mbere mu kohereza hanze PVC yo mu rwego rwa ethylene ku isi.
