Polimeri nziza-imwe iringaniza imiterere yumubiri nigikorwa cyibidukikije-ntikibaho, ariko polybutylene adipate co-terephthalate (PBAT) yegera kurusha benshi.
Abakora polymrike yubukorikori bamaze imyaka ibarirwa muri za mirongo bananiwe guhagarika ibicuruzwa byabo kurangirira mu myanda n’inyanja, kandi ubu bafite igitutu cyo gufata inshingano.Benshi barikubye kabiri imbaraga zo kongera gutunganya ibicuruzwa kugirango birinde abanegura.Andi masosiyete aragerageza gukemura ikibazo cy’imyanda ashora imari muri plastiki y’ibinyabuzima ishobora kwangirika nka aside polylactique (PLA) na polyhydroxyalkanoate (PHA), yizera ko iyangirika ry’ibinyabuzima rizagabanya nibura imyanda imwe n'imwe.
Ariko byombi gutunganya no gukoresha biopolymers bihura nimbogamizi.Nubwo hashize imyaka myinshi hashyizweho ingufu, igipimo cyo gutunganya plastiki muri Amerika, urugero, kiracyari munsi ya 10%.Kandi biopolymers-akenshi ikomoka kuri fermentation-irwanira kugera kumikorere imwe nubunini bwinganda za polymrike yashizweho bagenewe gusimbuza.
PBAT ikomatanya bimwe mubintu byingirakamaro biranga polimeri ya syntetique na biobased polymers.Bikomoka kuri peteroli isanzwe - acide terephthalic aside (PTA), butanediol, na aside adipic - nyamara irashobora kwangirika.Nka polymer yubukorikori, irashobora gukorwa byoroshye murwego runini, kandi ifite imiterere yumubiri ikenewe kugirango ikore firime zoroshye zirwanya iziva muri plastiki zisanzwe.
Uruganda rukora PTA mu Bushinwa.Ibisobanuro ntibisobanutse, kandi isosiyete ntishobora kuboneka kugirango itangwe ibisobanuro.Mu bitangazamakuru no kumenyekanisha imari, Hengli yavuze mu buryo butandukanye ko iteganya uruganda rwa t 450.000 cyangwa uruganda rwa t 600.000 rwa plastiki ishobora kwangirika.Ariko iyo isobanura ibikoresho bikenewe mu ishoramari, isosiyete ivuga PTA, butanediol, na aside adipic.
PBAT zahabu yihuta nini mubushinwa.Ikwirakwizwa ry’imiti mu Bushinwa CHEMDO umushinga ko umusaruro wa PBAT w’Abashinwa uzazamuka ugera kuri t 400.000 muri 2022 uva kuri 150.000 t muri 2020.
