Yingxowa yeplastiki eyenziwe ngeplastiki eyonakalayo:
1. Iiplastiki ezonakaliswayo:
Iplastiki eyonakaliswayo ibhekisela kumlinganiselo othile wezongezelelo (ezifana nesitashi, isitashi esilungisiweyo okanye enye i-cellulose, i-photosensitizers, i-biodegradants, njl.) eyongeziweyo kwinkqubo yokuvelisa ukunciphisa ukuzinza kwayo kwaye emva koko iyancipha ngokulula kwindawo yendalo.
2.Ukuhlelwa:
Iiplastiki ezonakaliswayo zohlulwe ngokubanzi ngokweendidi ezine:
①Ifoto yeplastiki eyonakalayo
Ukubandakanya i-photosensitizer kwiiplastiki, iiplastiki zibola ngokuthe ngcembe phantsi kokukhanya kwelanga. Kungokwesizukulwana sangaphambili seeplastiki ezichithwayo, kwaye ukungonakali kwayo kukuba ixesha lokuthotywa linzima ukuqikelela ngenxa yokutshintsha kokukhanya kwelanga kunye nemozulu, ngoko ixesha lokuthotywa alikwazi ukulawulwa.
②Iiplastiki ezinokubola
Isiphumo esifunwayo yiplastiki enokuthi igqitywe njengentsimi yeyeza leqela le-molecular. Ngeteknoloji yebhayoloji yanamhlanje, ingqwalasela engakumbi ihlawulwe kwiiplastiki ezinokubola, eziye zaba yindlela yophuhliso lophando nophuhliso.
③Iiplastiki ezikhanyayo/ezinokonakala
Uhlobo lweplastiki edibanisa i-photodegradation kunye ne-microorganisms, ineempawu zokukhanya kunye ne-microorganism iiplastiki ezichithwayo ngexesha elifanayo.
④Iiplastiki ezonakaliswa ngamanzi
Yongeza izinto ezifunxa amanzi kwiiplastiki, ezinokunyibilika emanzini emva kokusetyenziswa. Isetyenziselwa ikakhulu kwizixhobo zonyango kunye nezicoceko (ezifana neeglavu zonyango), ezilungele ukutshatyalaliswa kunye nokubulala iintsholongwane.
3. Intshayelelo:
Iimvavanyo zibonise ukuba iiplastiki ezininzi ezonakalayo ziqala ukuncipha, zinciphise umzimba, zilahlekelwe ngamandla, kwaye ngokuthe ngcembe ziqhekeke zibe ziziqwenga emva kweenyanga ezi-3 zokuvezwa kwindawo eqhelekileyo. Ukuba ezi ziqwenga zingcwatywe kwinkunkuma okanye emhlabeni, umphumo wokuthotywa awubonakali.

Imveliso yesitatshi sombona iyakwazi ukubola ngokupheleleyo, imathiriyeli ethembekileyo, eluhlaza kunye nokusingqongileyo.
Iphepha leKraft lenziwe ngezinto zePLA
Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo, kwaye ekugqibeleni ivelise i-carbon dioxide kunye namanzi
