1. Incamake y'uruhererekane rw'inganda:
Izina ryuzuye rya aside polylactic ni aside polylactic cyangwa aside polylactic. Ni ibikoresho bya polyester bifite molekile nyinshi biboneka binyuze mu gupomera hamwe na aside lactic cyangwa aside lactic dimer lactide nka monomer. Ni igikoresho cy’ibikoresho bya sintetike bifite molekile nyinshi kandi bifite imiterere y’ibinyabuzima n’uburyo bwo kwangirika. Kuri ubu, aside polylactic ni pulasitiki ishobora kwangirika ifite inganda zikuze cyane, umusaruro munini kandi ikoreshwa cyane ku isi. Inganda zikora aside polylactic ni ubwoko bwose bw’ibikoresho by’ibanze, nk’ibigori, ibisheke, beterave, nibindi, hagati ni ugutegura aside polylactic, naho hasi ni ugukoresha aside polylactic, harimo ibikoresho byo ku meza birinda ibidukikije, gupakira kurengera ibidukikije, nibindi.
2. Inganda zizamuka
Kugeza ubu, ibikoresho fatizo by’inganda zikora aside polylactic mu gihugu ni aside lactic, kandi aside lactic ikunze gutegurwa mu bigori, ibisheke, beterave n’ibindi bikomoka ku buhinzi. Kubwibyo, inganda zihinga ibihingwa ziganjemo ibigori ni inganda zikora aside polylactic. Ukurikije umusaruro w’ibigori mu Bushinwa n’agace gahingwamo ibigori, umusaruro w’ibigori mu Bushinwa uzagera kuri toni miliyoni 272.55 mu 2021, ku bwinshi, kandi ubuso bwo guteramo bumaze imyaka myinshi buhagaze neza kuri hegitari miliyoni 40-45. Ukurikije umusaruro w’ibigori mu Bushinwa mu gihe kirekire, biteganyijwe ko umusaruro w’ibigori uzakomeza kuba mwiza mu gihe kizaza.
Ku bijyanye n'ibindi bikoresho fatizo bishobora gukoreshwa mu gukora aside lactic, nk'ibisheke na beterave, umusaruro wose w'Ubushinwa mu 2021 wari toni miliyoni 15.662, wari munsi y'uwo mu myaka yashize, ariko ukiri ku rwego rusanzwe. Kandi ibigo hirya no hino ku isi birimo gushakisha uburyo bushya bwo gutegura aside lactic, nko gukoresha isukari ikomoka mu nsinga z'ibiti nk'ibyatsi n'umukungugu mu gutegura aside lactic cyangwa gushakisha uburyo bwo gukoresha methane mu gukora aside lactic. Muri rusange, umusaruro w'inganda zizamuka za aside polylactic uzaba uhamye mu gihe kizaza.
3. Inganda zo hagati
Kubera ko ari ibikoresho bishobora kubora burundu, aside polylactic ishobora gutuma ibikoresho fatizo bitangira gukoreshwa mu buryo bwo kuvugurura no kongera gukoresha ibikoresho, bufite ibyiza kurusha ibikoresho bishingiye kuri peteroli. Kubwibyo, ikoreshwa rya aside polylactic ku isoko ry'imbere mu gihugu riri kwiyongera. Ikoreshwa ry'imbere mu gihugu muri 2021 ni toni 48071.9, ubwiyongere bwa 40% ugereranyije n'umwaka.
Bitewe n’ubushobozi buke bw’umusaruro wa aside polylactic mu Bushinwa, ingano ya aside polylactic itumizwa mu Bushinwa ni nini cyane ugereranyije n’ingano yoherezwa mu mahanga. Mu myaka ya vuba aha, ingano ya aside polylactic itumizwa mu mahanga yariyongereye cyane bitewe n’ibikenewe mu gihugu. Mu 2021, aside polylactic itumizwa mu mahanga yageze kuri toni 25294.9. Kohereza mu mahanga aside polylactic nabyo byateye imbere cyane mu 2021, bigera kuri toni 6205.5, ubwiyongere bwa 117% buri mwaka.
Raporo ijyanye nayo: raporo ku isesengura ry'imigendekere y'iterambere n'iteganyagihe ry'iterambere ry'inganda z'ibikomoka kuri aside polylactic mu Bushinwa kuva mu 2022 kugeza 2028 yatanzwe na Zhiyan consulting
4. Inganda zikiri inyuma
Mu bikorwa byo hasi, aside polylactic yakoreshejwe mu nzego nyinshi zitandukanye kubera ubushobozi bwayo bwo guhuza ibintu n'ibinyabuzima no kubora. Kuri ubu, yakoreshejwe cyane mu gupfunyika ibiryo, ibikoresho byo ku meza, gupfunyika mu mifuka n'ibindi bicuruzwa. Urugero, firime ya pulasitiki y'ubuhinzi ikozwe muri aside polylactic ishobora kwangirika burundu ikabura nyuma yo gusarura imyaka, ibyo ntibizagabanya amazi n'uburumbuke bw'ubutaka, ariko kandi birinda amafaranga y'inyongera asabwa kugira ngo firime ya pulasitiki igarurwe, ari na yo nzira rusange yo guteza imbere firime ya pulasitiki mu Bushinwa mu gihe kizaza. Akarere gatwikiriwe na firime ya pulasitiki mu Bushinwa kangana na hegitari 18000, kandi ikoreshwa rya firime ya pulasitiki mu 2020 ni toni 1357000. Iyo firime ya pulasitiki ishobora kwangirika ishobora gukwirakwizwa, inganda za aside polylactic zifite umwanya munini wo guteza imbere mu gihe kizaza.
