Nkibikorwa byinshi-byubaka, kubaka ibikoresho byo mu rwego rwa selile ether birashobora kunoza uburyo bwo gufata amazi no kubyimba ibintu byubaka, kandi bigateza imbere ubwubatsi. Ikoreshwa cyane mugutezimbere no gutezimbere harimo minisiteri yububoshyi, minisiteri yubushyuhe bwamashyanyarazi, minisiteri yo guhuza amabati, minisiteri yo kwisiga, ndetse no gukora ibikoresho byubaka birimo inganda za PVC, gukora amarangi ya latx, gushiramo amazi, n'ibindi, bituma byuzuza ibisabwa byubaka ingufu no kurengera ibidukikije, kunoza imikorere yubwubatsi nubwubatsi. Ubwubatsi bwa Masonry na plaster, imitako yimbere ninyuma birahuye nicyerekezo cyiterambere cya politiki yinganda zigihugu mu kuzigama ingufu no kurengera ibidukikije ibikoresho bishya byubaka. Isosiyete yubaka ibikoresho byo mu rwego rwa selireose ether ahanini ni ibikoresho byo mu rwego rwo hejuru byubaka ibyiciro bya HPMC, kandi mubikorwa byingenzi byashyizwemo harimo minisiteri yubushyuhe bwo gutwika amashyanyarazi, gufatira tile, kwishyira hamwe, gufunga urukuta hamwe nandi mashyamba avanze yumye, hamwe na chloride polyvinyl (PVC), amashanyarazi ya elegitoroniki nindi mirima; hari nibicuruzwa bimwe bisanzwe, bikoreshwa cyane cyane mumashanyarazi avanze, minisiteri isanzwe hamwe no gusiba inkuta.
Bitewe nigipimo kinini cyishoramari mubijyanye nubwubatsi bwubwubatsi, isoko ryagutse hamwe nibisabwa byinshi, isoko rusange ryo kubaka ibikoresho byo mu rwego rwa selile ya selile irarenze cyane icyifuzo cya selile ya selile mu zindi nzego. Ikoreshwa cyane cyane muri minisiteri yuzuye ivanze, umukozi uhuza, PVC, putty, nibindi. Kugeza ubu, igihugu cyanjye gisaba kubaka ether ya selile yo mu rwego rwo hejuru (harimo ubwubatsi, PVC hamwe n’ibitambaro) irenga 90% by’ibisabwa kuri ether selile idafite ionic.
Ariko ukurikije isi yose, hafi 52% ya ether ya selile idafite ionic ikoreshwa mubijyanye nibikoresho byubaka, biri munsi yurwego rwimbere. Impamvu nyamukuru nuko, kuruhande rumwe, igipimo cyishoramari mubijyanye nubwubatsi mu gihugu cyanjye ari kinini kandi kigenda cyiyongera. Nubwo umuvuduko wubwiyongere ugenda gahoro, ingano ni nini; Kubwibyo, igihugu cyanjye cyubaka ibikoresho bya selile selile ether ifite ibiranga uburyo bwagutse bwo gusaba, isoko ryinshi, hamwe nabakiriya batatanye. Hashingiwe kuri toni 220.000 zubaka ibikoresho byo mu rwego rwa selireose ether isabwa ku isoko ryimbere mu gihugu mu mwaka wa 2018 hamwe n’ikigereranyo cyo hagati ya 25.000 yu / toni, ibikoresho byo mu rugo ibikoresho byo mu rwego rwa selile selile ether ingana na miliyari 5.5.
Kubijyanye no kubaka urwego rwibikoresho bitari ionic selulose ether, hari ibintu bibiri biranga. Mbere ya byose, yibasiwe cyane ninganda zo hasi nko kubaka ubwubatsi, imitungo itimukanwa no gushushanya. Mu myaka yashize, nubwo igihugu cyanjye gishora imari mu mutungo utimukanwa hamwe n’ahantu hubakwa imishinga iteza imbere imitungo itimukanwa yiyongereye uko umwaka utashye, umuvuduko w’ubwiyongere wagabanutse cyane. Mu buryo nk'ubwo, umuvuduko w’ubwiyongere bw’umusaruro w’igihugu wateguwe na minisiteri ivanze na kote yagabanutse.
Ikindi kiranga ni uko politiki iyobora iterambere ry’inyubako zicyatsi, zizigama ingufu n’ibidukikije ndetse no kohereza abakiriya mu mahanga mu Bushinwa, ibyo bikaba bikuraho ingaruka z’igabanuka ry’izamuka ry’imitungo itimbere mu gihugu. “Gahunda yimyaka 13 nagatanu yo kubaka ingufu zo kubungabunga ingufu no guteza imbere kubaka icyatsi” ishyira imbere intego. Muri 2020, ingufu zikoreshwa mu nyubako nshya zo mu mijyi ziziyongera 20% ugereranije na 2015; igipimo cyubuso bwicyatsi kibisi mumyubakire mishya yimijyi kizarenga 50%, naho igipimo cyibikoresho byubaka icyatsi kizakoreshwa Kurenga 40%; ubuso bwo kuvugurura ingufu zizigama inyubako zisanzweho ni metero zirenga miliyoni 500, naho kuvugurura ingufu zubaka amazu rusange ni metero kare miliyoni 100. Umubare w'inyubako zizigama ingufu mu nyubako zisanzwe zituwe mu mijyi no mu mijyi hirya no hino mu gihugu zirenga 60%. Iterambere rya selile ether ritanga inkunga ya politiki. Nyuma y’ihungabana ry’ibihugu by’i Burayi mu mwaka wa 2012, abakiriya bo mu bihugu bimwe na bimwe bongereye kugura selile ya selile mu Bushinwa no mu bindi bihugu bikiri mu nzira y'amajyambere hagamijwe guhangana n’ikibazo no kugabanya ibiciro.
