HDPE ifite ibikorwa byiza biranga imbaraga nziza, gukomera kwiza, gukomera gukomeye, hamwe no kurwanya ruswa, kutirinda amazi nubushuhe, ubushyuhe nubukonje bukabije, kubwibyo rero bifite akamaro gakomeye muburyo bwo guhumeka, kubumba inshinge no mu miyoboro.Hamwe nogushiraho imigendekere yinganda nka plastiki aho kuba ibyuma, plastike aho kuba ibiti, HDPE nkibikoresho bya polyethylene ikora cyane bizihutisha gusimbuza ibikoresho gakondo mugihe kizaza.Nkibikoresho byingenzi bya firime yubuhinzi nogupakira, LDPE irutwa na LLDPE mumbaraga zubukanishi, kubika ubushyuhe hamwe nubushuhe bwamazi, hamwe no kurwanya ruswa.Kubwibyo, isoko rya LLDPE ryiyongereye cyane mumyaka yashize, buhoro buhoro rimira umugabane w isoko rya LDPE.

1. Urunigi rwa polyethylene (PE)

Polyethylene nimwe mubintu bitanu byingenzi byubukorikori, ariko kandi nubushobozi bunini bwo kubyaza umusaruro ibikoresho byo mu rugo, bitumiza amoko menshi.Kuberako polyethylene iri hejuru ya Ethylene, umusaruro ushingiye ahanini kumuhanda wa naftha, kandi inyungu irasa.

Ikoreshwa ryinshi rya polyethylene ni firime, ikaba yari hafi 54% byicyifuzo cya polyethylene muri 2020. Byongeye kandi, ibikoresho byigituba bingana na 12%, ibikoresho bitoboye bingana na 12%, kubumba inshinge byari 11%, naho insinga gushushanya bingana na 4%.

2. Ibihe byubu byinganda za polyethylene (PE)

Mu myaka yashize, umusaruro wa polyethylene mu gihugu wiyongereye uko umwaka utashye.Kugeza mu 2021, umusaruro wa polyethylene mu gihugu ugera kuri toni 25.746.300, wiyongereyeho 11.8% ku mwaka.

Ku bijyanye n'umusaruro, guhera mu 2018, umusaruro wa polyethylene w'Ubushinwa wagiye wiyongera.Muri 2018, Ubushinwa umusaruro wa polyethylene wari hafi toni miliyoni 16.26, ukagera kuri toni miliyoni 22.72 mu 2021, ugereranyije n’ubwiyongere bw’umwaka buri mwaka bwiyongereyeho 11.8% muri icyo gihe.

Kuva mu 2015 kugeza 2020, bigaragara ko ikoreshwa rya polyethylene mu Bushinwa ryagiye ryiyongera buhoro buhoro, naho mu 2021, bigaragara ko ikoreshwa rya polyethylene mu Bushinwa ryaragabanutse kugera kuri toni 37.365.000, byagabanutseho 3,2% umwaka ushize.Ahanini bitewe n'ingaruka z'icyorezo no kugenzura kabiri gukoresha ingufu, inganda zimwe zo hepfo zahagaritse cyangwa zigabanya umusaruro.Hamwe no kunoza kwihaza, kwishingira ibicuruzwa biva muri PE bizagenda bigabanuka buhoro buhoro.Mu bihe biri imbere, hamwe n’iterambere ry’icyorezo n’iterambere ry’ubukungu bw’imbere mu gihugu, icyifuzo cya PE kizakomeza kwiyongera.

Nk’uko imibare ya gasutamo ibigaragaza, kuva muri Mutarama kugeza Gashyantare 2022, ibicuruzwa byose byatumijwe mu mahanga byari hafi toni 2,217.900, bikaba 13.46% ugereranije n’icyo gihe cyashize umwaka ushize.Igihugu cyacu polyethylene itumiza muri Arabiya Sawudite umubare munini, ibicuruzwa bitumizwa mu mahanga ni toni 475.900, bingana na 21.46%;Iya kabiri ni Irani, itumizwa muri toni 328.300, ihwanye na 14.80%;Iya gatatu ni Leta zunze ubumwe z'Abarabu, hamwe na toni 299.600 zitumizwa mu mahanga, zingana na 13.51%.

Ku bijyanye n’ibicuruzwa byoherezwa mu mahanga, kuva muri Mutarama kugeza Gashyantare 2022, ibicuruzwa biva mu mahanga bya polyethylene mu Bushinwa byagabanutse, mu gihe bitandukanye cyane n’ibyoherezwa mu mahanga byazamutse cyane.Toni zigera ku 53.100 za polyethylene zoherejwe muri Mutarama-Gashyantare 2022, ziyongereyeho 29,76% ugereranije n'icyo gihe cyashize.By'umwihariko, LDPE yohereza hafi toni 22.100, HDPE yohereza hafi toni 25.400, naho LLDPE yohereza hafi toni 50,600.

3. Ibibazo bya tekiniki yinganda za polyethylene (PE)

Kugeza ubu, iterambere ry’ikoranabuhanga rya polyethylene mu Bushinwa rifite ibibazo bikurikira:

(1) Kubura ikoranabuhanga rigezweho rya polyethylene.Mu Bushinwa, uruganda rukora imiti rwa Fushun Ethylene rukoresha ikoranabuhanga rya Sclairtech mu gukora ibicuruzwa bya octene 1 ya cololymerisation, kandi uruganda rukora peteroli rwa Shanghai Jinshan rwonyine rufite tekinoroji ya Borealis Bostar y'Amajyaruguru.Kwinjiza tekinoroji ya tekinoroji ya Dow Chemical Co, LTD ntabwo yatangijwe mubushinwa.
