Iiplastiki zeBio-basedzifumana ukuthandwa kwezi ntsuku ngenxa yokonakaliswa kwezinto eziphilayo kunye nezixhobo ezivuselelekayo.Iiplastiki zeBio-based zenziwe ngemithombo eqhelekileyo efana nombona, iimbotyi zesoya kunye nommoba.Ezi zixhobo zisetyenziswa endaweni yeplastiki yamafutha efosili, ezinegalelo elikhulu kwiingxaki zokusingqongileyo zehlabathi namhlanje.Nangona kunjalo, inkqubo yabo yokuvelisa kunye nefuthe lokusingqongileyo, kunye nokusebenza kunye nokusetyenziswa kwabo, kuhlala kungumngeni kwishishini.
Inkqubo yokuvelisa iiplastiki ezisekwe kwibhayoloji isoloko ifuna ixesha elininzi kunye nomzamo kuneeplastiki eziqhelekileyo.Izinto ezisetyenziswa ekrwada ukuvelisa ezi plastiki zifumana i-enzymatic okanye iikhemikhali reactions ukuvelisa ulwakhiwo olufunwayo lwepolymer.Ukongezelela, ezi nkqubo zihlala zibandakanya ukusetyenziswa kobushushu obuphezulu, obunokuchaphazela umgangatho wemveliso yokugqibela.Nangona kunjalo, ngaphandle kwemingeni ebangelwa yinkqubo yabo yokuvelisa,iiplastiki ezisekelwe kwizinto eziphilayoziya zisetyenziselwa ukuvelisa iimveliso eziluncedo.
Enye yeenzuzo ezibalulekileyo zeplastiki esekwe kwibhayoloji yimpembelelo yazo yokusingqongileyo.Iiplastiki ezisekwe kwibhayoloji zinezinga eliphantsi kakhulu lokukhutshwa kwegesi yegreenhouse kuneeplastiki eziqhelekileyo.Zikwayi-biodegradable, okuthetha ukuba ziyaqhekeka zibe ziinxalenye zazo zendalo ngexesha elithile.Umzekelo,iingxowa zegrosari, izitya zokutya, iibhotile, izityakwayeiikomityiezenziwe kwiiplastiki ze-bio-based zinika ukhetho oluluhlaza ngenxa yokuba zinokuvundiswa emva kokusetyenziswa.
Iiplastiki ze-Bio-based nazo zineempawu ezizodwa kunye nokusetyenziswa okubenza ukuba balungele ukusetyenziswa kwezinto ezahlukeneyo.Umzekelo, iiplastiki ezisekwe kwibhayolo zihlala ixesha elide kwaye zikhaphukhaphu kuneeplastiki zesiqhelo, zizenza zilungele ukuveliswa kwef.izitya ze ood kunye nokupakishwa.Ukongeza, iiplastiki ezisekwe kwibhayoloji zinokubunjwa zibe ziimo ezahlukeneyo zosetyenziso olwahlukeneyo.Ezi zakhiwo zibenza ukuba babe yeyona ndlela ibalaseleyo kwiiplastiki zesintu.
Ngaphandle koncedo olukhulu lweeplastiki ezisekwe kwibhayoloji, izinga labo lokwamkelwa lihlala lisezantsi ngokwentelekiso.Nangona kunjalo, lo mkhwa uyatshintsha.Imfuno yeiimveliso ezizinzileyo nezinobuhlobo nokusingqongileyoiyakhula, kwaye ngenxa yoko, iinkampani ezininzi ngakumbi zifuna ukubuyisela iiplastiki zemveli kunye neenketho ezisekelwe kwi-bio.Ukwamkelwa kweeplastiki ezisekelwe kwibhayoloji nako kunokukhokelela kumathuba amatsha emarike kunye nophuhliso lweiimveliso ezintsha.
Isishwankathelo, imeko yeeplastiki ezisekelwe kwi-bio kwishishini litshintsha ngokukhawuleza.Ngaphandle kwemiceli mngeni eyenziwa yinkqubo yokuvelisa kunye nefuthe lokusingqongileyo, iiplastiki ezisekwe kwibhayoloji zibonelela ngeenzuzo ezinkulu ezingenakungahoywa.Iimpawu zayo ezizodwa kunye nokusetyenziswa kwayo kuyenza ibe yeyona ndlela ibalaseleyo kwiiplastiki eziqhelekileyo, phakathi kwemfuno ekhulayo evela kubathengi abafuna ukusebenzisa ukhetho oluzinzileyo kunye nokusingqongileyo.Ukusukaiingxowa zegrosari kwizikhongozeli, iibhotile, izitya kunye neekomityi, iiplastiki ezisekelwe kwibhayoloji zingqina ukubaluleka kwazo kwimarike njengenye indlela egqwesileyo kwiiplastiki eziqhelekileyo.
