Amakuru y’ubutaka aragabanuka cyane, kandi PVC iragaragara.

Ku wa mbere, amakuru y’ubutaka yakomeje kugenda buhoro, byagize ingaruka mbi cyane ku byitezwe ku busabe bw’imigabane. Mu mpera z’uyu mwaka, amasezerano nyamukuru ya PVC yagabanutseho ibirenze 2%. Mu cyumweru gishize, amakuru ya CPI ya Amerika muri Nyakanga yari make ugereranyije n’uko byari byitezwe, ibyo bikaba byongereye ubushake bw’abashoramari bwo kubona inyungu. Muri icyo gihe kandi, ubusabe bwa zahabu, ifeza icyenda n’ibihe icumi by’ibiciro byari byitezwe ko buzamuka, ibyo bikaba byaratanze inkunga ku biciro. Ariko, isoko rifite gushidikanya ku kuntu ubusabe buhagaze mu kuzamuka kw’isaha. Ubwiyongere bwatewe no kuzamuka kw’isaha y’imbere mu gihugu mu gihe giciriritse n’igihe kirekire bushobora kutabasha gukuraho ukwiyongera kwatewe no kuzamuka kw’isaha y’imigabane n’igabanuka ry’isaha y’ibiciro byatewe n’isaha y’izamuka ry’ibiciro bitewe n’igitutu cy’ihungabana ry’ubukungu. Nyuma, bishobora gutuma ibiciro by’ibicuruzwa bizamuka, kandi bitewe n’igisubizo cy’izamuka ry’ibiciro, ntabwo bishoboka ko inyungu z’ifaranga rya Fed zizagabanuka cyane, ibyo bikaba binashyira igitutu ku biciro bya disiki.

Mu by’ukuri, ibyo abantu batari biteze ku isoko rya PVC byaragabanutse, ariko nta bintu byinshi byiza bivugwa mu gihe gito. Muri iki cyumweru, inyubako za PVC zatangiye kugabanuka gato, kandi urwego rwo kubungabunga rwarenze. Mu ntangiriro, bitewe n’impamvu zo kubungabunga ibihe, ibikoresho byo guparika byakomeje gukora kimwe ku kindi, kandi uruhande rw’ibikoresho by’ubwikorezi byitezwe ko ruzazamuka. Ariko, igihombo cy’inyungu ku gicuruzwa kimwe cya karuboni, intangiriro y’inyubako iragabanuka, kandi uruhande rw’ibikenewe ni byinshi. Bigaragarira mu byo isoko ryitezweho, bitewe n’ingaruka ziherutse z’ibihe by’akazi mu gihugu no guhagarika icyorezo no kugabanuka kw’ibikenewe hanze bitewe n’igitutu cy’ihungabana ry’ubukungu, ibikorwa byo mu nzira yo hasi birinda cyane, bikomeza kuvugurura ibintu byari bikenewe, bigatuma ububiko bw’ibikoresho byo mu gihugu buzamuka, ari nabyo bigabanya ibiciro. Nubwo igiciro cya disiki cyagabanutseho ikiguzi cy’ubucuruzi bwo hanze bwa karuboni carbide V, ibintu by’ibanze byo kugabanya ikiguzi biragoye guteza imbere izamuka ry’ibiciro rihoraho rya disiki, ariko bitewe n’ikiguzi gito gishyigikira igiciro kiri hasi, ihungabana ry’igihe gito naryo ni rito.

Muri rusange, ibintu byatumye ibiciro bikomeza kuzamuka mu ntangiriro byagabanutse ugereranyije n'uko byari bimeze ubu. Nyuma y'izamuka ry'ibiciro mu minsi ishize, igabanuka ry'amakuru ku mitungo itimukanwa ryashyize igitutu kinini ku biciro. Mu gihe igihembwe cy'ingufu z'imbere mu gihugu, zahabu, icyenda, feza, na cumi zikoreshwa mu gihe gito kirimo kwegereza, hari icyizere cyo kunoza ibisabwa. Impinduka mu bisabwa mu gihe gito zizaba intandaro y'impinduka mu biciro biherutse. Witondere iterambere ry'ibikenewe. Biteganijwe ko igiciro cy'igihe gito kizakomeza guhindagurika.
