El upulasitiki Ingenye yezinto ezisetshenziswa kakhulu emhlabeni. Kunezinhlobo zonke zemikhiqizo eyenziwe ngepulasitiki eyenziwe ngokususelwa ku- i-petroleum.
Kepha emashumini ambalwa eminyaka, uwoyela uzophela futhi intengo yawo izobiza kakhulu, ngakho-ke ngeke isasetshenziselwa ukwenza amapulasitiki. Ngalesi sizathu, kuphenywa izinketho ezahlukahlukene futhi zenzelwe ukudala bioplastics ukufaka esikhundleni salowo owenziwe ngokususelwa kuphethiloli.
Bafuna izinto zokusetshenziswa ezishibhile, ezemvelo futhi ezibolayo ngokubolayo ukuze udoti ungabi yinkinga.
ENyuvesi yaseNebraska-Lincoln baphenya ukuthi kungenzeka yini ukuthi kukhiqizwe i-bioplastic ngokuya ngezimpaphe zenkukhu. Le nto imfucumfucu yemboni yokudla njengoba ingasetshenziswa.
Abaphenyi banentshisekelo ezimpapheni ngoba ziqukethe iphrotheni eyaziwa ngokuthi i-keratin enezimfanelo ezinamandla neziqinile.
Inqubo yokuthola le bioplastic iqukethe ukwelashwa kokushisa ukuze uwahlanze, bese efakwa impuphu aze aguqulwe abe yimpuphu ecolekileyo. Ngemuva kwalokho amanye amakhemikhali ayanezelwa ukwenza i-keratin iphenduke i-polymer.
Lokhu okutholwayo kungabumba ukushisa, ngakho-ke kungasetshenziselwa ukusetshenziswa okuhlukile namafomu afana nepulasitiki yendabuko.
Esinye isici esihle ukuthi singaphinde senziwe kabusha izikhathi eziningana futhi -ngenzeka ngakho-ke i-eco-friendly ngempela.
Lolu hlobo locwaningo lubaluleke kakhulu ngoba kungekudala uwoyela ngeke usasetshenziselwa inani lemikhiqizo engenakubalwa. Ngakho-ke kufanele kufunwe ezinye izindlela ngoba imikhiqizo eyenziwe ngopulasitiki iyadingeka.
Kunamathuba amaningi okuthuthuka kwama-bioplastics anezinto ezahlukahlukene, ubunzima ukuthi impahla eluhlaza igcwele nokuthi izindleko zokukhiqiza ziyonga ngoba imikhiqizo yepulasitiki ishibhile.
UMTHOMBO: Ibhulogi eluhlaza
