Bioplastique ni ibikoresho bya pulasitiki bikozwe muri biomass aho kuba peteroli na gaze gasanzwe.Bangiza ibidukikije ariko bikunda kuba bitaramba kandi byoroshye kuruta plastiki gakondo.Ntabwo nazo zihamye iyo zihuye nubushyuhe.
Ku bw'amahirwe, abahanga bo muri kaminuza ya Akron (UA) babonye igisubizo kuri iyi nenge ya nyuma barenze ubushobozi bwa bioplastique.Iterambere ryabo rishobora gutanga umusanzu ukomeye muburyo burambye bwa plastiki mugihe kizaza.
Shi-Qing Wang, laboratoire ya PhD muri UA, irimo gutegura ingamba zifatika zo guhindura polymers zoroshye mu bikoresho bikomeye kandi byoroshye.Itsinda ryiterambere ryanyuma ni prototype ya polylactique (PLA) igikombe gikabije cyane, kibonerana, kandi ntigishobora kugabanuka cyangwa guhinduka mugihe cyuzuyemo amazi abira.
Plastike yahindutse igice cyingenzi mubuzima bwacu bwa buri munsi, ariko ibyinshi muri byo ntibishobora gukoreshwa bityo bikarundarunda mumyanda.Bimwe mubyiringiro biodegradable / ifumbire mvaruganda nka PLA akenshi ntibifite imbaraga zihagije zo gusimbuza lisansi gakondo ishingiye kuri polymers nka polyethylene terephthalate (PET) kuko ibyo bikoresho birambye birakomeye.
PLA nuburyo buzwi bwa bioplastique ikoreshwa mubipfunyika nibikoresho kuko bihendutse kubyara.Mbere yuko laboratoire ya Wang ikora ibi, gukoresha PLA byari bike kuko bidashobora kwihanganira ubushyuhe bwinshi.Niyo mpamvu ubu bushakashatsi bushobora kuba intambwe ku isoko rya PLA.
Dr. Ramani Narayan, umuhanga mu bya bioplastique akaba n'umwarimu wa kaminuza muri kaminuza ya Leta ya Michigan, yagize ati:
PLA nuyoboye isi 100% biodegradable kandi polymer yuzuye.Ariko ifite imbaraga nke zingufu hamwe nubushyuhe buke bwo kugoreka.Yoroshya kandi igasenyuka muburyo bwa dogere 140 F, bigatuma idakwiriye kubwoko bwinshi bwibiryo bishyushye hamwe nibikoresho byabitswe.Ubushakashatsi bwa Dr. Wang bushobora kuba intambwe yiterambere kuko igikombe cye cya prototype PLA kirakomeye, kibonerana, kandi gishobora gufata amazi abira.
Itsinda ryongeye gusuzuma imiterere igoye ya plastike ya PLA kurwego rwa molekile kugirango igere ku bushyuhe no guhindagurika.Ibi bikoresho bigizwe na molekile zumunyururu zifatanije nka spaghetti, zifatanije.Kugirango ube thermoplastique ikomeye, abashakashatsi bagombaga kureba niba kristu itabangamiye imiterere yububoshyi.Yabisobanuye nkumwanya wo gutoragura icyarimwe icyarimwe hamwe na chopsticks, aho kuba inyama nkeya zinyerera zisigaye.
Porotipiki yabo ya plastike ya PLA irashobora gufata amazi itangirika, kugabanuka cyangwa guhinduka.Ibikombe birashobora gukoreshwa nkibidukikije byangiza ibidukikije ubundi ikawa cyangwa icyayi.
