Ngaphantsi kwamaza ophuhliso oluzinzileyo lwehlabathi, ukutya-inqanaba le-polylactic acid(PLA) itafileiba yeyona nto iphambili kwinguqu eluhlaza kwishishini lokutya elinomkhuba ongathintekiyo, kwaye amathemba ayo kwimarike yehlabathi aqaqambile.

Ukhuseleko lokusingqongileyo yeyona nto iphambili eyenza ukuba ukutya kwe-PLA tableware kugqame kwimarike yehlabathi. Ngokuvuswa okuqhubekayo kolwazi lwendalo esingqongileyo lwabathengi behlabathi, abantu banikela ingqalelo ngakumbi nangakumbi kungcoliseko lokusingqongileyo olubangelwa yimveli.iitafile zeplastiki. Ngokwedatha evela kwiNkqubo yeZizwe eziManyeneyo yokusiNgqongileyo, malunga ne-8 yezigidi zeetoni zenkunkuma yeplastiki ingena elwandle minyaka le. Itafile ye-PLA isebenzisa izityalo ezivuselelekayo ezifana nombona kunye nommoba njengemathiriyeli ekrwada. Kwimeko yokwenziwa komgquba kwimizi-mveliso, izinga lokuthotywa lingafikelela ngaphezu kwe-90% kwiinyanga nje ezi-6, kwaye ekugqibeleni libole libe yikharbon diokside namanzi, nto leyo edambisa kakhulu ingxaki yongcoliseko lweplastiki. Umzekelo, ngexesha leeOlimpiki zaseBusika eBeijing ngo-2022, umsitho wamkelwe ngokupheleleyo iPLA tableware, ebonisa umhlaba ukuba nokwenzeka kokusetyenziswa kwawo ngomlinganiselo omkhulu, otsale umdla kunye nokuxelisa abaninzi.abaququzeleli bemisitho emikhulukumhlaba jikelele. ​

Ukhuseleko sisiqinisekiso esibalulekileyo se-PLA tableware yokutya ukuze uphumelele ukuthembela kubathengi behlabathi. Kuye kwaqinisekiswa yimibutho egunyazwe ngamazwe ngamazwe njenge-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA), ukuqinisekisa ukuba ayinayo izinto ezinobungozi ezifana ne-plasticizers kunye ne-bisphenol A. Ngokwahlukileyo, i-tableware yendabuko ye-melamine inokukhupha i-carcinogens efana ne-formaldehyde phantsi kobushushu obuphezulu okanye indawo ethile, ngelixa i-PLA ibeka i-tableware ye-tableware ngaphandle.ukhuseleko lokutyaiyenze yasetyenziswa ngokubanzi kwiindawo ezineemfuno eziphakamileyo zokhuseleko njengamakhaya, izikolo, nezibhedlele ehlabathini lonke.

Iqhutywa yiteknoloji entsha, ukusebenza kwebakala lokutyaItafile ye-PLAiye yalungiswa ngokuqhubekayo kwaye iimeko zayo ezisebenzayo ziye zandiswa ngakumbi. Ngokusebenzisa ukuguqulwa kwekristallisation, ubushushu balo bokuguqulwa kobushushu bonyuswe kakhulu ukusuka kwi-56 ° C ukuya kwi-132 ° C; emva kokudibanisa ne-PBAT, ukunyuswa kwayo ngexesha lokuphumla kuye kwandiswa ukuya ngaphezu kwe-100%, enokuthi ihlangabezane neemfuno zokupakishwa kokutya okufriziwe. Ukongeza, iimpawu zayo zokucwangcisa ubushushu obuphantsi azigcini nje ukunciphisa ukusetyenziswa kwamandla ngama-30%, kodwa ziyakwazi ukulungelelaniswa nezixhobo zeplastiki ezikhoyo, ukutsala iinkampani ezininzi zokutya kunye nabavelisi emhlabeni jikelele. EYurophu naseUnited States, amatyathanga okutya okukhawulezayo ngakumbi nangakumbi aqalisile ukusebenzisa iibhokisi zesidlo sasemini sePLA; e-Asiya, iivenkile ezithengisa izinto lula eJapan zikwasebenzise ifilimu yokutya ye-PLA ukupakisha ukutya
Kwinqanaba lomgaqo-nkqubo, amazwe amaninzi kwihlabathi jikelele aqalise ngokusebenzayo imigaqo-nkqubo efanelekileyo yokukhusela uphuhliso lwemarike yetafile ye-PLA yokutya. I-China iphumeza umgaqo-nkqubo wembuyekezo ye-VAT kubavelisi be-PLA, kwaye ifuna ukuncitshiswa kwe-30% kwizinto ezingonakali.iitafile zeplastikikwibala lokuthatha nge-2025 "I-Plastiki Ban"; I-European Union ityale i-300 yezigidi zeeyuro kwisicwangciso se-Horizon Europe, izinikele ekufezekiseni i-100% yokuphinda kusetyenziswe inkunkuma ye-PLA ngo-2030; I-California kunye neminye imimandla e-United States nayo ikhuphe ngokulandelelana imimiselo yothintelo lweplastiki ukukhuthaza ukusetyenziswa kwezinto ezinokonakala ezifana ne-PLA. Ukuphunyezwa kwale migaqo-nkqubo kukhuthaze ukukhula okukhawulezayo komgangatho wokutya we-PLA tableware market. ​

Idatha yemarike ibonisa ngokuthe ngqo amandla amakhulu ophuhliso lwetafile ye-PLA yokutya. Ngokwengxelo yaseTshayina yoPhando kunye nokuNxulumanisa, ubungakanani bemarike yetafile yebhayoloji elahlayo ifikelele kwi-12.2 yeebhiliyoni zeedola ngo-2024 kwaye kulindeleke ukuba ikhule iye kwi-18.6 yeebhiliyoni zeedola ngo-2034. I-Hengxin Life, inkampani ekhokelayo kushishino, iya kuba nengeniso ye-1.594 yebhiliyoni ye-yuan ngo-2024, kunye nokwanda kwe-7 kwi-% yokuqala ye-7. ikota ka-2025. Ingeniso yayo evela kwiimveliso ezonakeleyo ibalelwa ngaphezulu kwe-54%, ethe yatsala ingqalelo yenkunzi yehlabathi kwishishini le-PLA tableware. ​
Ngaphandle kwamathemba abanzi, uphuhliso lwetafile ye-PLA yebakala lokutya kwimarike yehlabathi isajongene nemingeni ethile, efana nokungonelanga kokumelana nobushushu kweemveliso ezingalungiswanga kunye nokuthotywa phantsi kwemekobume yendalo echatshazelwa bubushushu. Nangona kunjalo, ngotyalo-mali oluqhubekayo lwamandla ophando lwenzululwazi yehlabathi, ezi ngxaki ziphuculwa ngokuthe ngcembe. Inokubonwa kwangaphambili ukuba iqhutywa ziimfuno zokhuseleko lokusingqongileyo, inkxaso yomgaqo-nkqubo kunye nenkqubela phambili yetekhnoloji, i-tableware ye-PLA yokutya iya kuhlala kwindawo ebaluleke ngakumbi kwimarike yehlabathi kwaye ikhokele ishishini lokutya libe kwixesha elitshaukukhuselwa kokusingqongileyo okuluhlaza.
