Ni ibihe bibazo biri ku isoko ry’inkunga yo gutunganya PVC?

1. Haracyari icyuho gifatika hagati y’ibikoresho byo gutunganya PVC byo mu gihugu n’ibicuruzwa byo mu mahanga, kandi ibiciro biri hasi ntabwo bifite inyungu nini mu ipiganwa ku isoko.
Nubwo ibicuruzwa byo mu gihugu bifite inyungu zimwe na zimwe mu irushanwa ry’isoko, hari icyuho mu mikorere y’ibicuruzwa, ubwoko butandukanye, ituze, n’ibindi ugereranije n’ibicuruzwa byo mu mahanga. Ibi bifitanye isano n’uko formula y’ibicuruzwa byacu, ikoranabuhanga ryo kubitunganya, gutunganya no kubitunganya nyuma yo kubitunganya bisigaye inyuma. Hari ibigo bimwe na bimwe byo mu gihugu bizi neza ibi bibazo kandi byagiranye umubano w’ubufatanye n’ibigo by’ubushakashatsi, ibigo by’ubushakashatsi n’iterambere, kandi byakoze ubushakashatsi ku bikoresho bya pulasitiki.
2. Inganda nto ziratandukanye kandi nta kigo gikomeye gifite umwanya uhamye, bigatuma habaho ipiganwa ritameze neza ku isoko.
Kugeza ubu, hari inganda zigera kuri 30 zikora ACR zo mu gihugu, ariko 4 muri zo ni zo zifite umusaruro munini (zifite ubushobozi bwo gushyiramo toni zirenga 5000 buri mwaka). Ibicuruzwa by'izi nganda nini byagaragaje isura nziza ku masoko yo mu gihugu no mu mahanga, hatitawe ku bwoko bw'ibicuruzwa n'ubwiza bwabyo. Ariko mu myaka ibiri ishize, bitewe n'iterambere ry'inganda zitunganya PVC, zimwe mu nganda nto za ACR zifite ubushobozi bwo gukora toni zitarenze 1000 zagiye ku isoko. Bitewe n'ibikoresho byoroshye byo gukora no kudahindagurika kw'ibicuruzwa, izi nganda zishobora kubaho gusa hakoreshejwe uburyo bwo gusuka imyanda ku giciro gito, bigatuma habaho ipiganwa rikomeye ku isoko ry'imbere mu gihugu. Bimwe mu bicuruzwa bifite ubuziranenge buke kandi biri hasi byahise byuzura ku isoko, bizana ingaruka mbi ku nganda zitunganya imyanda ndetse binazana ingaruka mbi zikomeye ku iterambere ry'inganda. Ni byiza ko Ishyirahamwe ritunganya Plastic rifata iya mbere mu gushyiraho Ishyirahamwe ry'Inganda zikora ACR Additive, rihuza amahame y'inganda, rigenga iterambere ry'inganda, rikuraho ibicuruzwa by'impimbano n'ibitari byiza, kandi rigabanye ipiganwa rikabije. Muri icyo gihe, ibigo binini bigomba kongera imbaraga mu guteza imbere ibicuruzwa, guhindura imiterere y'ibicuruzwa byabyo, no gukomeza iterambere rihuza n'ibindi bicuruzwa bisa n'ibyo mu mahanga.
3. Izamuka ry'ibiciro bya peteroli ryatumye ibiciro by'ibikoresho fatizo byiyongera ndetse n'inyungu z'ibigo zigabanuka.
Bitewe n’izamuka rikomeje ry’ibiciro bya peteroli mpuzamahanga, ibikoresho byose by’ingenzi bikorerwa mu ikorwa rya ACR, methyl methacrylate na acrylic ester, byazamutse cyane. Ariko, abakiriya bo mu gihe gito basigaye inyuma mu kwiyongera kw’ibiciro by’ibicuruzwa, bigatuma inyungu muri rusange ku bigo bitunganya ACR zigabanuka. Ibi byatumye inganda zose zitakaza igihombo mu 2003 na 2004. Kuri ubu, bitewe n’izamuka ry’ibiciro by’ibikoresho, inganda zagaragaje icyerekezo cyiza cyo kunguka.
4. Ubushakashatsi ku nganda ntibwashoboye gutera imbere mu buryo bwimbitse, kubera kubura impano z'umwuga
Bitewe n'uko inyongeramusaruro ya ACR ari inyongeramusaruro y'ibikoresho bya polymer yatangiriye mu Bushinwa mu mpera za 1990, amashami yayo y'ubushakashatsi n'iterambere n'abashakashatsi ni bake ugereranyije n'izindi nyongeramusaruro nka pulasitiki n'ibindi bigabanya umuriro mu Bushinwa. Nubwo hari ibigo by'ubushakashatsi byigenga biyiteza imbere, kutagira ubufatanye bwiza hagati y'abashakashatsi n'inganda zitunganya pulasitiki byatumye ubushakashatsi ku bicuruzwa budashobora gukosorwa. Kuri ubu, iterambere rya ACR mu Bushinwa rishingiye gusa ku bigo by'ubushakashatsi bifite ibigo bike kugira ngo biyitegure kandi biyiteze imbere. Nubwo hari ibyagezweho, hari icyuho kinini hagati y'ibigo by'ubushakashatsi byo mu gihugu n'iby'amahanga mu bijyanye n'inkunga y'ubushakashatsi, ibikoresho by'ubushakashatsi n'iterambere, hamwe n'ireme ry'ubushakashatsi n'iterambere. Niba iki kibazo kitaranozwa cyane, ntabwo bizaba bizwi niba ibikoresho byo gutunganya bishobora gukomera ku isoko ry'imbere mu gihugu mu gihe kizaza.
