Abantu bose bazi ibikoresho bifasha gutunganya PVC. Ni ibihe bibazo bifitanye isano na PVC itunganya inganda?

1. Ikoranabuhanga rya MBS n'iterambere biratinda, kandi isoko ni ryagutse, ariko umugabane ku isoko ry'ibicuruzwa byo mu gihugu ni muto.

Nubwo imaze imyaka irenga 20 yiterambere, inganda zo mu gihugu MBS muri iki gihe ziri mu ntangiriro, kandi nta bicuruzwa by’isosiyete bishobora guhangana n’ibicuruzwa by’amahanga nk’imfashanyigisho za PVC. Ibigo byinshi bihari bihura nuruhererekane rwibibazo nko guhitamo ibikoresho bidahagije, inzira ya synthesis idahindagurika, no kubura intambwe mu ikoranabuhanga rya synthesis. Ndetse n'ibigo byinshi ntabwo bifite ibikoresho bya styrene butadiene latex synthesis kandi birashobora kugura gusa MBS idasanzwe ya styrene butadiene latex kugirango ikorwe na MBS, kandi ubwiza bwibicuruzwa byabo birashobora gutekerezwa. Kugeza ubu, ibicuruzwa byinshi byinjijwe ku isoko bishingiye ku nyungu z’ibiciro kandi bikoreshwa ku bicuruzwa bya PVC bidasaba ubuziranenge bw’ibicuruzwa. Ku isoko ryo mu rwego rwo hejuru, umugabane w’isoko ni muto kandi nturagira ingaruka ku masosiyete y’amahanga. Biteganijwe ko ibicuruzwa bitumizwa mu 2006 bizaba hagati ya toni 50000 na 60000, bingana na 70% by’ibisabwa byose.

2. Hariho abashakashatsi nibigo bike byubushakashatsi, binaniwe gushiraho imbaraga zihuriweho niterambere ryubumenyi nikoranabuhanga.

Nubwo MBS yashyizwe ku rutonde nkumushinga w’ubushakashatsi mu bumenyi n’ikoranabuhanga mu gihugu inshuro nyinshi, ntabwo iragera ku ntera ishimishije. Impamvu nyamukuru nuko abashakashatsi ari bake kandi ishoramari rike mu ikoranabuhanga. Kugeza ubu, haracyari ibigo byubushakashatsi mu nganda bikora ubushakashatsi bwigenga kandi bigashaka intambwe, ariko ubu bushakashatsi niterambere ryiterambere birashobora gufatwa nkigikundiro ugereranije nitsinda ryamahanga hamwe nitsinda rinini ryubushakashatsi bwa siyanse.

3. Kugeza ubu, urwego rwimfashanyigisho za PVC mu Bushinwa ruri hafi y’ibicuruzwa byo hanze, ariko kubera ibiciro by’ibiciro bya CPE, biragoye kubiteza imbere. Kujya kwisi yose no guhangana nibicuruzwa byo hanze kumasoko mpuzamahanga bizaba amahitamo meza. Nyamara, igicuruzwa kimwe kiriho hamwe n’umutekano muke bizaba ikibazo cyihutirwa kubashinzwe inganda gukemura
