Plastic bụ otu n'ime isi mmalite mmetọ kachasị na mbara ala, ọ na-ewekwa ọtụtụ narị afọ iji mebie ya. Dị ka akụkọ mgbasa ozi si mba ọzọ si kwuo, ndị na-eme nchọpụta na Ụlọ Akwụkwọ Gburugburu Ebe obibi nke Mahadum Yale na Mahadum Maryland ejirila ihe ndị sitere na osisi mepụta bioplastics na-adịgide adịgide ma na-adịgide adịgide iji dozie otu n'ime nsogbu gburugburu ebe obibi kachasị njọ n'ụwa.

Onye enyemaka Prọfesọ Yuan Yao nke Ụlọ Akwụkwọ Gburugburu Ebe Obibi nke Mahadum Yale na Prọfesọ Liangbing Hu nke Mahadum Maryland Center for Materials Innovation na ndị ọzọ jikọrọ aka na nyocha iji wulite matrix porous n'ime osisi sitere n'okike ka ọ bụrụ slurry. Ndị nchọpụta ahụ kwuru na plastik biomass arụpụtara na-egosipụta ike na nkwụsi ike dị elu mgbe enwere mmiri mmiri, yana nguzogide UV. Enwere ike ịmegharị ya na gburugburu ebe obibi ma ọ bụ mebie ya n'enweghị nsogbu. E jiri ya tụnyere rọba ndị nwere mmanụ ala na plastik ndị ọzọ nwere ike imebi ndụ, mmetụta gburugburu ebe obibi ndụ ya pere mpe.

Yao kwuru, sị: "Anyị ewepụtala usoro nrụpụta dị mfe ma kwụ ọtọ nke nwere ike iji osisi na-emepụta plastik nke dabeere na bio ma nwee ezigbo akụrụngwa."

Iji mee ngwakọta slurry ahụ, ndị nyocha ahụ jiri ibe osisi dị ka ihe akụrụngwa wee jiri ihe mgbaze dị omimi eutectic na-emebi emebi na nke a na-emegharịgharị na-arụzi ihe na-adịghị mma na ntụ ntụ. Na ngwakọta nke enwetara, n'ihi nano-scale entanglement na hydrogen bonding n'etiti lignin na-emezigharị na cellulose micro / nano fiber, ihe ahụ nwere nnukwu ọdịnaya siri ike na nnukwu viscosity, a pụkwara ịwụpụ ya ma tụgharịa na-enweghị mgbawa.

Ndị nchọpụta ahụ meziri nyocha usoro ndụ zuru oke iji nwalee mmetụta gburugburu ebe obibi nke bioplastics na plastik nkịtị. Nsonaazụ gosiri na mgbe e liri mpempe akwụkwọ bioplastic n'ime ala, a na-agbaji ihe ahụ mgbe izu abụọ gasịrị ma mebie kpamkpam mgbe ọnwa atọ gasịrị; Tụkwasị na nke ahụ, ndị nchọpụta ahụ kwuru na a pụkwara ịgbaji bioplastics ahụ ka ọ bụrụ slurry site na mkpali igwe. Ya mere, a na-enwetaghachi DES ma jiri ya mee ihe ọzọ. Yao kwuru, sị: "Uru nke plastik a bụ na enwere ike ịmegharị ya kpamkpam ma ọ bụ mebie ya. Anyị ebelatala ihe mkpofu ihe na-asọba na okike."

Prọfesọ Liangbing Hu kwuru na bioplastic a nwere ọtụtụ ngwa ngwa, dịka ọmụmaatụ, enwere ike ịkpụ ya ka ọ bụrụ ihe nkiri maka iji na akpa rọba na nkwakọ ngwaahịa. Nke a bụ otu n'ime ihe ndị a na-eji plastik eme ihe na otu n'ime ihe na-akpata nsị. Na mgbakwunye, ndị nyocha ahụ kwuru na enwere ike ịkpụzi bioplastic a ka ọ bụrụ ụdị dị iche iche, yabụ a na-atụkwa anya na a ga-eji ya n'ichepụta ụgbọ ala.

Ndị otu ahụ ga-aga n'ihu na-enyocha mmetụta nke ịba ụba mmepụta ihe na oke ohia, n'ihi na nnukwu mmepụta ihe nwere ike ịchọ iji osisi buru ibu, nke nwere ike inwe mmetụta dị ukwuu n'oké ọhịa, njikwa ala, gburugburu ebe obibi, na mgbanwe ihu igwe. Ndị otu nyocha ahụ ejirila ndị ọkachamara n'ihe gbasara oke ọhịa rụọ ọrụ iji mepụta ụdị ịme anwansị ọhịa nke jikọtara usoro uto ọhịa na usoro nrụpụta osisi-plastic.
