Icya gatatu, uruhande rutanga: kurekura ubushobozi bushya biratinda, igipimo cyimikorere kirebwa ninyungu
PVC irekura ubushobozi bushya iratinda.Mu myaka yashize, umuvuduko wumusaruro wubushobozi bushya bwa PVC uri munsi yibyateganijwe.Nubwo hari gahunda nyinshi zo kubyaza umusaruro, inyinshi murizo zitinda kubyaza umusaruro umusaruro kubera gahunda yumusaruro udashyizwe mubikorwa uyumwaka, kandi nibikorwa nyirizina biratinda.Kubwibyo, ibisohoka bya PVC bigira ingaruka cyane kubikoresho byo kubika.Igipimo cyimikorere ya PVC cyerekana inyungu zayo bwite.Kubera inyungu nziza muri Werurwe, ibigo bimwe na bimwe bya PVC byasubitse kubungabunga muri Gicurasi, kandi igipimo cy’ibikorwa cyageze kuri 81% muri Werurwe, kirenga urwego mpuzandengo rw’imyaka yashize.Umusaruro wose mu mezi atanu ya mbere ya 2022 wageze kuri toni miliyoni 9.687, uri munsi gato ugereranije na toni miliyoni 9.609 mugihe kimwe cyumwaka ushize no hejuru yikigereranyo cyimyaka yashize.Muri rusange, igiciro cya karisiyumu ya calcium kumpera yikiguzi kiragabanuka vuba, kandi inyungu yinganda zikora PVC ninziza mugihe kinini.Kubwibyo, nubwo urwego rwigihe kimwe cyumwaka ushize rwaragabanutse, igipimo cyibikorwa bya PVC uyumwaka kiracyari kurwego rwo hejuru mumateka.
Kwishingikiriza kumasoko yatumijwe muri PVC ntabwo ari menshi, igipimo cy’isoko ryo gutumiza mu mahanga kiragoye gufungura, igipimo cy’ibicuruzwa byatumijwe muri uyu mwaka biragaragara ko kiri munsi y’urwego mu myaka yashize.Disiki yo hanze ni inzira ya Ethylene, bityo igiciro ni kinini, kandi kwinjiza ibicuruzwa bizagira ingaruka nke kubitangwa muri rusange.
Iv.Uruhande rusabwa: Inkunga yoherezwa mu mahanga irakomeye, kandi "ibyifuzo bikomeye" byifuzo byimbere mu gihugu biha inzira "intege nke"
Mu 2022, igabanuka ry’inyungu z’imbere mu gihugu hamwe n’ingamba zo guhagarika iterambere ryatangijwe, kandi ibyifuzo bikomeye byabaye inshuro nyinshi kuruhande rusabwa.Nubwo ibyoherezwa mu mahanga byazamutse vuba kuruta uko byari byitezwe, icyifuzo cy’imbere mu gihugu nticyigeze gisubira inyuma ku buryo bugaragara, kandi ukuri gukomeye kurenze ibyateganijwe.Ikigaragara cyo gukoresha PVC kuva muri Mutarama kugeza muri Mata cyageze kuri toni 6.884.300, cyamanutseho 2,91% ugereranije n’icyo gihe cyashize umwaka ushize, bitewe ahanini no gukurura ibikenewe mu gihugu.Igihembwe cya mbere nigihe gito cyibisabwa, gukoresha PVC bifite ibimenyetso bigaragara biranga ibihe, byerekana kugwa kwambere hanyuma kuzamuka.Mu gihembwe cya kabiri, hamwe n'ubushyuhe bwazamutse, PVC yagiye buhoro buhoro mu gihe cy’impinga, ariko icyifuzo cyo kurangiza icyifuzo muri Mata cyari munsi y’ibiteganijwe ku isoko.Ku bijyanye n’ibikenewe hanze, ibyoherezwa mu mahanga PVC mu gice cya mbere cy’umwaka byarenze izamuka ryateganijwe, kandi ingaruka z’ubucuruzi bw’amahanga zagaragaye.Ibyoherezwa mu mahanga kuva Mutarama kugeza Gicurasi byose hamwe byari toni 1.018.900, byiyongereyeho 4,8 ku ijana ugereranyije n'icyo gihe cyashize.Imbere ya calcium karbide yo murugo ugereranije na etylene yo mumahanga ifite inyungu zigaragara, ibicuruzwa byohereza ibicuruzwa hanze.Irangira rya politiki yo kurwanya ibicuruzwa mu Buhinde ryongereye igiciro cy’ibicuruzwa byoherezwa mu mahanga by’ifu ya PVC mu Bushinwa, byagaragaye ko muri Mata byiyongereyeho ibintu biturika, bikagera ku gipimo kinini cyoherezwa mu mahanga mu kwezi kumwe.
Hamwe n’izamuka ry’inyungu ryiyongera mu mahanga, umuvuduko w’ubukungu bw’amahanga uzagabanuka mu gice cya kabiri cy’umwaka, kandi kubura ibikenerwa hanze bizatuma igabanuka rikabije ry’ubwiyongere bw’ibicuruzwa byoherezwa mu mahanga PVC, ariko ibyoherezwa mu mahanga ingano iteganijwe gukomeza.Igurishwa ry’amazu yari asanzwe afite muri Amerika ryaragabanutseho 3,4% muri Gicurasi rigera kuri miliyoni 5.41 ku mwaka, urwego rwo hasi cyane kuva muri Kamena 2020, bishimangira uburyo ibiciro biri hejuru ndetse n’izamuka ry’inguzanyo bigenda bikenerwa.Mugihe imibare yo kugurisha imitungo itimukanwa yo muri Amerika igabanutse, ibyifuzo byo gutumiza hasi muri PVC bizagabanuka.PVC ikoreshwa cyane, ibicuruzwa byo hasi bigabanijwe cyane mubicuruzwa bikomeye nibicuruzwa byoroshye ibyiciro bibiri.Muri byo, imiyoboro n'imiyoboro ni igice kinini cyo gukoresha PVC mu gihugu cyacu, bingana na 36% by'ibikoreshwa byose bya PVC.Umwirondoro, inzugi na Windows nigice cya kabiri kinini mu baguzi, bingana na 14% byikoreshwa rya PVC yose, ikoreshwa cyane mugukora inzugi na Windows nibikoresho bizigama ingufu.Mubyongeyeho, PVC nayo ikoreshwa cyane mubigorofa, ku rubaho no ku rundi rubaho, firime, ikomeye n'andi mabati, ibicuruzwa byoroshye n'indi mirima.Imiyoboro ya PVC hamwe na profile bikoreshwa cyane cyane mubintu bitimukanwa nibikorwa remezo nibindi bice.Imikoreshereze yerekana ibihe bimwe na bimwe biranga ibihe, hamwe nububiko bwibanze mbere na nyuma yumunsi mukuru wimpeshyi season igihe cyo gukoresha igihembwe cya kabiri → zahabu icyenda ifeza icumi → urumuri mu mpera zumwaka.Inganda zo hasi za PVC zazamutse cyane kuva mu 2020, kandi ibicuruzwa byoherezwa mu mahanga byiyongereye uko umwaka utashye mu myaka ibiri ishize.Kuva muri Mutarama kugeza Gicurasi, ibicuruzwa byoherejwe mu igorofa ya PVC ni toni miliyoni 2,53, byoherezwa mu bihugu byateye imbere mu Burayi no muri Amerika.
Ishoramari ryimitungo itimukanwa ryakomeje gucika intege.Usibye umuvuduko wukwezi kumwe wokurangiza ntiwakomeje kugabanuka, umuvuduko wubwiyongere bwibicuruzwa, ubwubatsi bushya, ubwubatsi nubutaka bwubutaka byose byakomeje kugabanuka kandi murwego runini, kugeza ubwo igabanuka ryagabanutse muri Gicurasi.Politiki yatangiye gushyira ingufu, harimo guhindura igipimo ntarengwa cy’inyungu z’inguzanyo ku mazu ya mbere, kugabanya LPR y’imyaka itanu kurenza uko byari byitezwe, no gukuraho buhoro buhoro amategeko agenga kugura n’inguzanyo mu mijyi imwe n'imwe.Izi ngamba zigamije kunoza ibyifuzo no guhuza ibyifuzo.Mu cyiciro gikurikiraho, isoko ryimitungo iteganijwe gukira nabi.
PVC ni iy'ibicuruzwa nyuma yumuzingi wibintu bitimukanwa, kandi ibyifuzo byanyuma bifitanye isano numutungo utimukanwa.Icyifuzo cya PVC mumitungo itimukanwa kiri inyuma.Imikoreshereze igaragara ya PVC ifite ihuriro ryinshi hamwe no kurangiza, ikiri inyuma gato yintangiriro nshya.Muri Werurwe, iyubakwa ryinganda zo hasi ziyongera buhoro buhoro.Kwinjira mu gihembwe cya kabiri nigihembwe cyibisabwa, ariko imikorere nyayo iri munsi yibiteganijwe ku isoko.Bitewe n’iki cyorezo cyagize ingaruka ku ncuro nyinshi, igipimo cy’ibikorwa by’inganda zo hasi muri Mata na Gicurasi cyari munsi cyane ugereranije n’imyaka yashize.Kurekura ibyifuzo byukuri bikenera igihe, PVC ikeneye gukurikiranwa iracyakeneye gutegereza.
