Iindiza zephepha zayisisisombululo esilahlekileyo, kodwa imodeli entsha inokuba yimpendulo

Emva kokurhabula okumbalwa kwe-smoothie yam ye-strawberry-banana, ekuphela kwento endinokuyingcamla yayiyincasa embi, yamaphepha yomququ.
Ayizange ijike kuphela, kodwa iphinde yasonga yodwa, ithintela isiselo ukuba singaphumi sibheke phezulu.Ndawulahla umququ ndathatha entsha, enye istraw yephepha, kuba yayiyiyo yonke indawo yokutyela eyayiza kunikela ngayo.Umququ nawo awuzange ubambe ukumila kwawo, ndagqibezela isiselo sam ngaphandle komququ.
Iphepha lithatha ngokukhawuleza ulwelo, kwaye ngokukhawuleza lilahlekelwa yisakhiwo kunye nokuqina.Uphando olwenziwe yiKorea Research Institute of Chemical Technology (KRICT) lubonise ukuba iindiza zephepha ezimanzi, ezinobunzima obuyi-25 grams, zigoba emva kwemizuzwana engama-60.Ngenxa yoko, iindiza ezenziwe ngezinto ezichaziweyo ziye zangqineka zingathembekanga, ekubeni zihlala zingasebenziseki.
Iindiza zephepha ziyaphumelela ngenxa yokuba iindiza ezigqunyiweyo zophuka ngokukhawuleza kunezitro zeplastiki zesintu kwaye zihambelana nokusingqongileyo, kodwa ingxaki yeendiza ezimanzi isekhona.“
Ukulwa noku, ezinye iibrendi zenza imicu yephepha eligqunyiweyo (izinto ezifanayo njengeengxowa zeplastiki kunye neglu) ezithintela iphepha ukuba lingadibani nokufuma ngokukhawuleza.
Nangona kunjalo, ezi ndiza zithatha ixesha elide ukubola, ngakumbi elwandle.Oku kuchasene nenjongo yokukhupha iindiza zeplastiki, ezithatha iminyaka engama-300 ukubola xa kuthelekiswa neendiza ezenziwe ngephepha kuphela.
Nangona kunjalo, izitro zephepha zinobuhlobo kakhulu nokusingqongileyo kwaye izitro ezigqunyiweyo zibola ngokukhawuleza kunezitro zeplastiki zesintu, kodwa kusekho ingxaki yokufuma kwiindiza.Yile nto i-KRICT yayizama ukuyicombulula kwaye bayenzile.
Iqela lifumene i-coating of cellulose nanocrystals (PBS / BS-CNC) eyachithwa ngokupheleleyo kwiintsuku ze-120 kwaye igcina imilo yayo, ibambe i-50 grams nangemva kwemizuzwana ye-60.Kwelinye icala, ubungakanani bemiqukuzo yokugqibela ayicacanga, njengoko uhlobo oluthile lwezitro zephepha ezithe zathelekiswa nazo azikachazwanga kwaye zinokuba kumgangatho ophantsi kunezitro zesiqhelo kwimarike, kunye nokuqina kuyo yonke indawo. ubude.iindiza ezintsha azikangqinwa.Noko ke, ezi ndiza zitsha zangqineka zomelele.
Naxa ezi ngca ziphuculweyo zifikelela kwimarike yobuninzi, azisayi kwaneliseka.Iindiza zephepha ezigotywayo ngokuhamba kwexesha azinakuthelekiswa nezitro zeplastiki ngokwemiqathango yokugcinwa kwesakhiwo, oku kuthetha ukuba iinkampani ziya kuqhubeka nokuthengisa izitro zeplastiki kwaye abantu baya kuqhubeka nokuzithenga.
Nangona kunjalo, sisenako ukukhuthaza ukuveliswa kwezitro zeplastiki ezizinzileyo.Oku kubandakanya iindiza ezincinci, zombini ubukhulu kunye nobubanzi.Oku kuya kuthetha ukusebenzisa iplastiki encinci, oku kuthetha ukuba abayi kuphuka ngokukhawuleza, kodwa baya kusebenzisa izinto ezincinci: i-positive kumashishini abenzayo.
Ukongeza, abantu kufuneka bazame ukusebenzisa iindiza ezinokuphinda zisetyenziswe ezifana neendiza zentsimbi okanye izitro ze-bamboo ukunciphisa inkunkuma.Ewe kunjalo, imfuno yeendiza ezilahlwayo iya kuqhubeka, oku kuthetha ukuba iindiza ezifana ne-KRICT kunye nezo zisebenzisa iplastiki encinci ziyafuneka njengenye indlela kwiindiza zephepha.
Ngokubanzi, iindiza zephepha ziphelelwe lixesha.Azisiso isisombululo kubuninzi benkunkuma engonakaliyo eveliswa ngumququ.
Izisombululo zokwenyani kufuneka zifunyanwe, kuba iingozi kwimpilo yeplanethi sele zikhulu kakhulu, kwaye lo ngumququ wokugqibela.
