Ngaba iingxowa zeplastiki ezibolisiweyo ngenene zinokubola?
Ukunqongophala kwemithombo yobutyebi kunye nokungcoliseka kwendalo zezona ngxaki ziphambili abantu abajongana nazo xa beqonda imbono yophuhliso oluzinzileyo kwinkulungwane yama-21.I-Biotechnology iya kuba yenye yetekhnoloji engundoqo ukusombulula le ngxaki.Phakathi kwezinto ezininzi ezibangela ukungcoliseka kwendalo, ingxaki yendalo ebangelwa yinkunkuma yeplastiki iye yavusa inkxalabo ebanzi kuluntu.Okulandelayo, makhe sijonge ukuphuculwa kokusingqongileyo kweeplastiki ezinokonakala.
Iiplastiki ezonakeleyo ziiplastiki ezinokunyibilika ziintsholongwane ezisemhlabeni.Ngoncedo lweebhaktheriya okanye i-enzymes yabo ye-hydrolytic, ezi zinto zinokunyibilika kwi-carbon dioxide, amanzi, izixhobo ze-cellular porous kunye netyuwa, kwaye zinokuchithwa ngokupheleleyo yi-microorganisms kwaye ziphinde zingene kwi-ecosystem.Yindawo yophando kunye nophuhliso kumazwe kwihlabathi liphela namhlanje.
Ke ngoko, iplastiki ye-biodegradable ihlala ibhekisa kuhlobo olutsha lweplastiki enobunzima obunempembelelo ethile kwaye inokunyibilika ngokupheleleyo okanye ngokuyinxenye yibhaktheriya, ukubumba, i-algae kunye nezinye ii-microorganisms kwindawo yendalo ngaphandle kokubangela ungcoliseko lwendalo.Xa iibhaktheriya okanye ii-enzymes zabo ze-hydrolase ziguqula i-polymer ibe ngamaqhekeza amancinci, i-biodegradation iyenzeka, kwaye ibhaktheriya iyayinyibilika ibe yimichiza efana nekharbon diokside kunye namanzi.
Ngeli nqaku, wonke umntu kufuneka azi okuthile malunga neengxowa zeplastiki ezinokubola.Ukuba unayo nayiphi na imibuzo enxulumeneyo, nceda undwendwele iwebhusayithi yethu ukuze ubonisane, kwaye siya kukukhonza ngentliziyo epheleleyo!
