Plastike ni imwe mu masoko manini yanduye ku isi, kandi bisaba imyaka amagana kugirango yangirike bisanzwe. Nk’uko ibitangazamakuru byo mu mahanga bibitangaza, abashakashatsi bo mu Ishuri Rikuru ry’ibidukikije rya kaminuza ya Yale na kaminuza ya Maryland bakoresheje ibiti biva mu biti kugira ngo bakore bioplastike iramba kandi irambye kugira ngo bakemure kimwe mu bibazo by’ibidukikije byugarije isi.

Assistant Professor Yuan Yao wo mu Ishuri Rikuru ry’ibidukikije rya kaminuza ya Yale na Porofeseri Liangbing Hu wo muri kaminuza ya Maryland Centre ishinzwe ibikoresho bishya hamwe n’abandi bafatanyije mu bushakashatsi bwo kubaka matrike yamenetse mu biti karemano. Abashakashatsi bavuze ko plastiki ya biyomasi yakozwe yerekana imbaraga za tekinike kandi zihamye iyo zirimo amazi, ndetse no kurwanya UV. Irashobora kandi gukoreshwa neza mubidukikije cyangwa ibinyabuzima byangiritse neza. Ugereranije na peteroli ishingiye kuri peteroli hamwe n’ibindi bikoresho bya plastiki bishobora kwangirika, ingaruka z’ubuzima bw’ibidukikije ni nto.

Yao yagize ati: "Twateje imbere uburyo bworoshye kandi bworoshye bwo gukora bushobora gukoresha ibiti mu gukora plastiki zishingiye ku binyabuzima kandi bifite imiterere y’ubukanishi."

Mu rwego rwo gukora imvange ya slurry, abashakashatsi bifashishije imbaho ​​zinkwi nkibikoresho fatizo kandi bakoresheje ibinyabuzima byangirika kandi bigasubirwamo byangiza eutectic solvent kugirango berekane imiterere yuzuye ifu. Mu mvange yabonetse, bitewe na nano-nini yo kwizirika hamwe na hydrogène ihuza hagati ya lignine yongeye kuvuka hamwe na selile ya selile ya selile / nano fibre, ibikoresho bifite ibintu byinshi bikomeye hamwe nubukonje bwinshi, kandi birashobora gutabwa no kuzunguruka bitavunitse.

Abashakashatsi bakoze isuzuma ryuzuye ryubuzima kugirango bagerageze ingaruka z’ibidukikije na plastiki zisanzwe. Ibisubizo byerekanye ko igihe urupapuro rwa bioplastique rwashyinguwe mu butaka, ibikoresho byacitse nyuma yibyumweru bibiri kandi byangiritse rwose nyuma y amezi atatu; hiyongereyeho, abashakashatsi bavuze ko ibinyabuzima bishobora no gucikamo ibice binyuze mu gukanika imashini. Rero, DES iragarurwa kandi irakoreshwa. Yao yagize ati: "Ibyiza bya plastiki ni uko bishobora gutunganywa neza cyangwa bikabangikanywa. Twagabanije imyanda y’ibintu yinjira muri kamere."

Porofeseri Liangbing Hu yavuze ko iyi bioplastique ifite uburyo butandukanye bwo gukoresha, urugero, ishobora kubumbabumbwa muri firime kugira ngo ikoreshwe mu mifuka ya pulasitike no gupakira. Ubu ni bumwe mu buryo bukoreshwa bwa plastiki nimwe mu mpamvu zitera imyanda. Byongeye kandi, abashakashatsi bavuze ko iyi bioplastique ishobora kubumbabumbwa mu buryo butandukanye, bityo bikaba biteganijwe ko izakoreshwa no mu gukora imodoka.

Iri tsinda rizakomeza gushakisha ingaruka zo kwagura umusaruro w’amashyamba, kubera ko umusaruro munini ushobora gusaba gukoresha ibiti byinshi, bishobora kugira ingaruka zikomeye ku mashyamba, imicungire y’ubutaka, urusobe rw’ibinyabuzima, n’imihindagurikire y’ikirere. Itsinda ry’ubushakashatsi ryakoranye n’abashinzwe ibidukikije mu mashyamba kugira ngo bashireho icyitegererezo cy’amashyamba gihuza imikurire y’amashyamba n’ibikorwa byo gukora ibiti-plastiki.
