Utshani bephepha bebeyisixazululo esilahlekile, kodwa imodeli entsha ingaba yimpendulo

Ngemva kokuphuza okumbalwa kwe-smoothie yami ye-strawberry-banana, engangikwazi ukunambitha kwakuwukunambitheka okubi, okuyiphepha kotshani.
Ayigobile nje kuphela, kodwa futhi yagoqa yodwa, ivimbela isiphuzo ukuthi sigeleze siye phezulu.Ngawulahla utshani futhi ngathatha obusha, omunye utshani bephepha, ngoba kwakuyilokho kuphela indawo yokudlela okufanele inikeze.Utshani nalo lwalungabambeki, ngase ngiqeda isiphuzo sami ngaphandle kotshani.
Iphepha limunca uketshezi ngokushesha, futhi ngokushesha nje lilahlekelwa ukwakheka kwalo nokuqina.Ucwaningo olwenziwe yiKorea Research Institute of Chemical Technology (KRICT) luveze ukuthi izitsha zephepha ezimanzi, ezinesisindo esimaphakathi samagremu angama-25, ziyagoba ngemuva kwemizuzwana engama-60.Ngakho-ke, izinti ezenziwe ngezinto ezishiwo ziye zabonakala zingathembeki, ngoba ngokuvamile azisebenziseki.
Izinhlanga zephepha ziyawina ngenxa yokuthi izitshani ezimboziwe ziphuka ngokushesha kunezitsha zepulasitiki zendabuko futhi zinobungani bemvelo, kodwa inkinga yotshani obumanzi isekhona.“
Ukuze ulwe nalokhu, ezinye izinhlobo zenza izitsha zephepha ezinamekwe (izinto ezifanayo nezikhwama zepulasitiki neglue) ezivimbela iphepha ukuthi lihlangane nomswakama ngokushesha.
Nokho, lezi zinhlanga zithatha isikhathi eside ukubola, ikakhulukazi olwandle.Lokhu kungqubuzana nomgomo wokulahlwa kotshani bepulasitiki, okuthatha iminyaka efinyelela kwengama-300 ukubola uma kuqhathaniswa notshani enziwe ngephepha kuphela.
Kodwa-ke, izitsha zephepha zinobungane kakhulu kwimvelo futhi izinhlanga ezimboziwe zibola ngokushesha kunezitsha zepulasitiki zendabuko, kodwa kusekhona inkinga yomswakama ezinhlangeni.Yilokhu i-KRICT eyayizama ukukuxazulula futhi bakwenza.
Ithimba lithole ukumbozwa kwe-cellulose nanocrystals (PBS/BS-CNC) eyahlakazeka ngokuphelele phakathi kwezinsuku eziyi-120 futhi yagcina isimo sayo, ibambe amagremu angu-50 ngisho nangemva kwemizuzwana engu-60.Ngakolunye uhlangothi, ukuthi lezi zinhlanga zihlala kangakanani akucaci, njengoba uhlobo oluthile lwezinhlanga zephepha ezaziqhathaniswa nazo azikachazwa futhi zingase zibe nezinga eliphansi kunezinhlanga ezivamile emakethe, kanye nokuqina kuyo yonke indawo. ubude.ama-straw amasha awakafakazelwa.Nokho, lezi zinhlayiya ezintsha zabonakala ziqinile.
Ngisho noma lezi zinhlanga ezithuthukisiwe zifika emakethe yeningi, ngeke zenelise.Izinti zamaphepha ezigoqekayo ngokuhamba kwesikhathi azikwazi ukuqhathaniswa nezitsha zepulasitiki ngokugcinwa kwesakhiwo, okusho ukuthi izinkampani zizoqhubeka nokudayisa izitsha zepulasitiki futhi abantu baqhubeke nokuzithenga.
Kodwa-ke, sisengakwazi ukukhuthaza ukukhiqizwa kwezitsha zepulasitiki ezizinzile.Lokhu kuhlanganisa utshani obuncane, kokubili ubukhulu nobubanzi.Lokhu kuzosho ukusebenzisa ipulasitiki encane, okusho ukuthi ngeke nje baphule ngokushesha, kodwa futhi bazosebenzisa izinto ezincane: i-positive ezimbonini ezizenzayo.
Ukwengeza, abantu kufanele bazame ukusebenzisa izitsha ezingasebenziseka kabusha njengezitsha zensimbi noma izitsha zoqalo ukuze banciphise imfucuza.Yebo, isidingo sezitshani ezilahlwayo sizoqhubeka, okusho ukuthi izinhlanga ezifana ne-KRICT kanye nalezo ezisebenzisa ipulasitiki encane ziyadingeka njengenye indlela esikhundleni sephepha.
Ngokuvamile, ama-straws ephepha aphelelwe yisikhathi.Azisona isixazululo senani elikhulu lemfucuza engaboli ekhiqizwa ngotshani.
Izixazululo zangempela kufanele zitholakale, ngoba izingozi empilweni yeplanethi sezivele zikhulu kakhulu, futhi lokhu kuwutshani wokugcina.
