Iingcali zenzululwazi zenze inkqubela ebonakalayo kwintsimi yeeplastiki ezinokubola, inyathelo elibalulekileyo ekukhuseleni okusingqongileyo.Iqela lophando elivela kwiyunivesithi edumileyo liphuhlise ngempumelelo uhlobo olutsha lweplastiki eyonakaliswa kwisithuba seenyanga, inika isisombululo esinokubakho kwingxaki yongcoliseko lweplastiki ekhulayo.
Inkunkuma yeplastiki ibe yingxaki engxamisekileyo yehlabathi, kwaye iiplastiki zemveli zithatha amakhulu eminyaka ukubola.Le nkqubela phambili yophando inika ithemba eliqaqambileyo njengoko iiplastiki ezintsha ezinokuboliswa kubomi bemihla ngemihla zibonelela ngeendlela ezinokusetyenziswa kwiiplastiki zesintu ezingaboliyo nezenza umonakalo kwiilwandle zethu, iindawo zokulahla inkunkuma kunye nenkqubo yendalo.
Iqela lophando lisebenzise indibaniselwano yezinto zendalo kunye ne-nanotechnology ephezulu ukwenza le mpumelelo yeplastiki.Ngokubandakanya iipolymers ezisekelwe kwizityalo kunye ne-microbes kwinkqubo yokuvelisa, baye bakwazi ukwenza iplastiki enokuthi ihlelwe kwizinto ezingenabungozi ezifana namanzi kunye ne-carbon dioxide ngokusebenzisa iinkqubo zendalo zebhayoloji.
Olona ncedo luphambili lwale plastikhi esandula kuveliswa yibiodegradable lixesha lokubola kwayo.Ngelixa iiplastiki zemveli zinokuhlala amakhulu eminyaka, le plastiki ivelisa izinto ezintsha ithoba phakathi kweenyanga ezimbalwa, inciphisa kakhulu impembelelo yayo eyingozi kokusingqongileyo.Ngaphaya koko, inkqubo yokwenziwa kwale plastiki ineendleko eziphantsi kwaye izinzile, nto leyo eyenza ukuba ibe yindlela enokusebenziseka kumashishini ahlukeneyo.
Usetyenziso olunokubakho lwale plastikhi enokonakala kakhulu mikhulu.Iqela lophando linombono wezicelo zalo kwiinkalo ezahlukeneyo, kubandakanywa ukupakishwa, ezolimo kunye nempahla yabathengi.Ngenxa yexesha elifutshane lokuphumla, iplastiki inokujongana ngempumelelo nengxaki yenkunkuma yeplastiki eqokelelwa kwiindawo zokulahla inkunkuma, ehlala ithatha indawo kwizizukulwana.
Umqobo obalulekileyo iqela lophando eliye lawunqoba ngexesha lophuhliso yayingamandla kunye nokuqina kweplastiki.Kwixesha elidlulileyo, iiplastiki eziguquguqukayo ze-biodegradable zazihlala zithandeka ekuqhekekeni kwaye zingenako ukuqina okufunekayo ekusebenziseni ixesha elide.Nangona kunjalo, ngokusebenzisa i-nanotechnology, abaphandi bakwazi ukunyusa iipropathi zeplastiki, ziqinisekisa amandla kunye nokuqina ngelixa zigcina ukubola kwayo.
Ngelixa le mpumelelo yophando ngokuqinisekileyo iyathembisa, imiqobo emininzi kusafuneka yoyiswe phambi kokuba le plastiki yamkelwe ngomlinganiselo omkhulu.Ukuqinisekisa ukusebenza kunye nefuthe lexesha elide leplastiki, uvavanyo olongezelelweyo kunye nokulungiswa kuyadingeka.
Sekunjalo, le mpumelelo kuphando lweplastiki enokubola inika ithemba ngekamva eliluhlaza.Ngomzamo oqhubekayo kunye nenkxaso, olu phuhliso lunokuguqula indlela esijongana ngayo nokuveliswa kweplastiki, ukusetyenziswa kunye nokulahla, ukwenza igalelo elibalulekileyo ekusombululeni ingxaki yongcoliseko lweplastiki yehlabathi.
