Ihinduka ry’ibicuruzwa byatumijwe mu Bushinwa kuva 2004-2021 murashobora kubibona mu byiciro bine byerekana ko ibicuruzwa biva mu mahanga biva mu Bushinwa kuva 2004, nkuko byasobanuwe hano hepfo.

Icyiciro cya mbere ni 2004-2007, igihe Ubushinwa bwakeneraga plastike bwari buke kandi umubare w’ibicuruzwa byatumijwe mu mahanga ukomeza gukora ku buryo buke, kandi mu Bushinwa ibicuruzwa bitumizwa mu mahanga byari bike mu 2008 igihe ibigo bishya by’imbere mu gihugu byibandaga cyane kandi bikagira ikibazo gikomeye cy’amafaranga.

Icyiciro cya kabiri ni 2009-2016, Ubushinwa PE butumiza mu mahanga bwinjiye mu cyiciro gihamye nyuma yo kwiyongera gukomeye. 2009, kubera gutabarwa kw’imbere mu gihugu no mu mahanga, ubwishingizi bw’isi yose, ubwinshi bw’ubucuruzi rusange bw’imbere mu gihugu bwiyongereye, icyifuzo cy’ibicuruzwa cyari gishyushye, ibicuruzwa byatumijwe mu mahanga byiyongereye ku buryo bugaragara, aho izamuka ry’ivunjisha ryiyongereyeho 64.78%, hakurikiraho ivugururwa ry’ivunjisha mu mwaka wa 2010, igipimo cy’ivunjisha ry’ifaranga ryakomeje gushimwa, hamwe n’akarere k’ubucuruzi bw’ubucuruzi bw’ibihugu bya ASEAN Amasezerano y’ibanze yatangiriye gukurikizwa kandi igiciro cy’ibicuruzwa byatumijwe mu mahanga kigabanuka kugeza ku mwaka wa 2010 kugeza 2013. Umwaka wa 2014, ubushobozi bushya bwo gukora PE mu gihugu bwiyongereye ku buryo bugaragara, kandi umusaruro rusange w’ibikorwa rusange byiyongereye byihuse; mu 2016, Uburengerazuba bwakuyeho ku mugaragaro ibihano byafatiwe Irani, kandi amasoko ya Irani yari afite ubushake bwo kohereza mu Burayi hamwe n’ibiciro biri hejuru, icyo gihe ubwiyongere bw’ibicuruzwa byatumijwe mu gihugu bwaragabanutse.

Icyiciro cya gatatu ni 2017-2020, Ubushinwa bwinjira mu mahanga PE bwongeye kwiyongera cyane muri 2017, umusaruro w’imbere mu gihugu ndetse n’amahanga uragenda wiyongera ndetse n’umusaruro ukomoka mu mahanga, Ubushinwa, nk’igihugu kinini gikoresha PE, kiracyari ibicuruzwa byoherezwa mu mahanga ku bicuruzwa by’isi. 2017 kuva Ubushinwa bwinjira mu mahanga ibicuruzwa byinjira mu mahanga byiyongereye ku buryo bugaragara, kugeza mu mwaka wa 2020, hashyizwe ahagaragara ibikoresho bishya byo gutunganya no gukoresha ingufu za hydrocarubone mu Bushinwa, mu gihugu Icyakora, ukurikije uko byakoreshejwe, icyifuzo cyo mu mahanga cyibasiwe cyane n’icyorezo cy’icyorezo gishya, mu gihe ikibazo cyo gukumira icyorezo cy’icyorezo cy’Ubushinwa gihagaze neza kandi icyifuzo kikaba gifata iyambere mu kuzamuka kw’ibicuruzwa bikomoka mu Bushinwa ku giciro cyo hasi cy’ibicuruzwa, bityo Ubushinwa bukaba bugera ku bicuruzwa bikomoka mu Bushinwa ku giciro cyo hasi ku bicuruzwa, Toni miliyoni 18.53. Nyamara, ibintu bitera kwiyongera kwinshi kwa PE bitumizwa muri iki cyiciro ahanini ni ugukoresha ibicuruzwa aho gutwarwa n’ibisabwa byihuse, kandi igitutu cyo guhatanira amasoko haba mu gihugu ndetse no hanze yacyo kigaragara buhoro buhoro.

Mu 2021, Ubushinwa bwinjira mu mahanga bwinjira mu cyiciro gishya, kandi dukurikije imibare ya gasutamo, mu Bushinwa ibicuruzwa bitumizwa mu mahanga bizaba hafi toni miliyoni 14.59 mu 2021, bikamanuka kuri toni miliyoni 3.93 cyangwa 21.29% guhera mu 2020. Kubera ingaruka z’icyorezo cy’isi ku isi, ubushobozi bwo kohereza ibicuruzwa mu mahanga burakomeye, igipimo cy’imizigo yo mu nyanja cyiyongereye ku buryo bugaragara ku bicuruzwa 20 byoherezwa mu mahanga ndetse no hanze y’isoko, kwaguka, idirishya ryubukemurampaka imbere no hanze yisoko biracyagoye gufungura, ibicuruzwa mpuzamahanga bitumizwa mu mahanga bizakomeza kuba bike, kandi ibicuruzwa biva mu Bushinwa PE byinjira bishobora kumanuka mu gihe kiri imbere.

Kuva 2004-2021 Ubushinwa PE bwohereza ibicuruzwa muri buri bwoko, ubwinshi bw’ibicuruzwa bitumizwa mu Bushinwa PE ni bike kandi amplitude ni nini.

Kuva 2004 kugeza 2008, Ubushinwa PE bwohereza ibicuruzwa hanze muri toni 100.000. Nyuma ya Kamena 2009, igipimo cy’imisoro ku bicuruzwa byoherezwa mu mahanga ku bicuruzwa bimwe na bimwe bya plastiki n’ibicuruzwa byabo, nk’izindi polimeri zo mu bwoko bwa Ethylene polymers, byazamutse bigera kuri 13%, kandi ishyaka ryoherezwa mu mahanga mu gihugu ryiyongera.

Muri 2010-2011, ubwiyongere bw’ibicuruzwa byoherezwa mu gihugu byaragaragaye, ariko nyuma yibyo, ibyoherezwa mu mahanga byo mu gihugu byongeye guhura n’ikibazo, nubwo ubushobozi bw’umusaruro w’imbere mu gihugu bwiyongera, haracyari icyuho kinini mu itangwa ry’Ubushinwa PE, kandi biragoye kugira ubwiyongere bukabije bw’ibicuruzwa byoherezwa mu mahanga hashingiwe ku giciro, icyifuzo gikenewe ndetse n’inzitizi z’ubwikorezi.

Kuva mu mwaka wa 2011 kugeza 2020, ibicuruzwa byoherezwa mu mahanga mu Bushinwa byagabanutse cyane, kandi ibyoherezwa mu mahanga byari hagati ya toni 200.000-300.000. 2021, Ubushinwa PE bwohereza ibicuruzwa mu mahanga bwiyongereye, maze ibicuruzwa byoherezwa mu mahanga bigera kuri toni 510.000, byiyongeraho toni 260.000 ugereranije na 2020, byiyongera ku gipimo cya 104% umwaka ushize.

Impamvu ni uko nyuma ya 2020, Ubushinwa bunini bwo gutunganya no gucana hydrocarubone mu Bushinwa bizatangizwa hagati, kandi ubushobozi bwo kubyaza umusaruro buzasohoka neza mu 2021, kandi umusaruro w’Abashinwa PE uziyongera cyane cyane ubwoko bwa HDPE, hamwe n’ibikoresho byinshi biteganijwe ku bimera bishya ndetse no kongera umuvuduko w’ipiganwa ku isoko. Isoko riragenda ryiyongera, kandi kugurisha umutungo w’abashinwa PE muri Amerika yepfo n’ahandi biriyongera.

Ubwiyongere bukomeza bwubushobozi bwumusaruro nikibazo gikomeye kigomba guhura nacyo kuruhande rwabatanga PE. Kugeza ubu, kubera imbogamizi z’ibiciro, ibisabwa byujuje ubuziranenge hamwe n’ubwikorezi bwo gutwara abantu, biracyagoye kohereza ibicuruzwa hanze mu gihugu, ariko hamwe n’ubwiyongere bukabije bw’umusaruro w’imbere mu gihugu, ni ngombwa guharanira kugurisha mu mahanga. Umuvuduko wamarushanwa ya PE ku isi yose mugihe kiri imbere uragenda urushaho gukomera, kandi uburyo bwo gutanga nibisabwa kumasoko yimbere mugihugu ndetse n’amahanga aracyakeneye kwitabwaho.
