Impahla eyinhloko yenkomishi yephepha yiphepha, kanti impahla yokuqala yephepha isihlahla noqalo.Abantu abaningi abakwazi ukusiza kodwa baphikisa ngokuthi uma ukuthuthukiswa okukhulu kokukhiqizwa kwenkomishi yephepha kuzoholela ekusetshenzisweni okukhulu kwezinkuni, futhi kuzophumela ekumoshweni kwezinsiza ezihlobene, kuzophinde kucekele phansi imvelo yemvelo ngezinga elikhulu. .Lolu hlobo lomcabango luyaqondakala, lungase lube ngaphandle komcabango wamanye amacala okucekelwa phansi kwemithombo yamahlathi ngokungafanele, okushiya umbono omubi kakhulu, nokho, ukugawulwa kwamahlathi kwanamuhla kuye kwavinjwa ngokuphumelelayo ngaphansi kwezinqubomgomo nemithetho eqinile yombuso.Njengamanje, zonke izinto zokusetshenziswa zamapulangwe esizisebenzisayo zingamahlathi avuselelwe ahlelelwe kahle angagawulwa, imodeli yosizo isihlahla sehlathi esingokomnotho esingasetshenziswa ngokunengqondo.Ngakho-ke, imboni yokukhiqiza indebe yephepha izoqhuba kuphela ukuthuthukiswa kwezimboni ezihlobene, inqobo nje uma ukulawula okunengqondo, ngeke kube khona isigameko sokucekelwa phansi kwemvelo kwemvelo abantu abakhathazeke ngakho.I-Paper Cups yahola imboni yokuqala yokuthuthukiswa yimboni yephepha, ngoba impahla eyinhloko yezinkomishi zephepha yiphepha.Nakuba ukusetshenziswa kwamanje kwezihlahla esigabeni sokuhlela, kodwa ukuthuthukisa ukusetshenziswa okuphezulu kwezinkuni ekwenzeni iphepha kanye nokuthola ezinye izindlela ephepheni nakho kuyindaba yocwaningo oluqhubekayo.Ukunaka kwabantu imvelo, kodwa futhi ukukhuthaza abantu iphepha ifenisha ucwaningo kabusha.
Enye impahla eluhlaza yenkomishi yephepha yiphepha elimboziwe elifuywayo, iphepha elifakwe kwamanye amazwe le-PLA, iphepha elifakwe kwamanye amazwe le-PE.I-PE coating ingumshini wokumboza (umshini wokugcwalisa i-laminating) ephepheni onongqimba lwefilimu ye-PE (i-polyethylene) I-Polylactic acid fiber iyi-fiber yokwenziwa engaboli ngokuphelele engatholakala kuzinhlamvu.Imfucuza ingabola ibe yi-carbon dioxide namanzi ngama-microorganisms emhlabathini noma emanzini olwandle.Lapho ushisiwe, ngeke ukhiphe igesi enobuthi futhi ubangele okunye ukungcola.Kune-hydroxyl eyodwa neqembu elilodwa le-carboxyl ku-molecule ye-lactic acid eyodwa, ama-molecule amaningi e-lactic acid ehlangene,-OH namanye ama-molecule-COOH dehydration condensation,-COOH namanye ama-molecule-OH dehydration condensation, i-polymer eyakhayo ibizwa ngokuthi i-polylactic acid.I-Polylactic acid eyaziwa nangokuthi i-polylactide ingeyomndeni we-polyester.I-Polylactic acid (PLA) iwuhlobo lwe-polymer material engatholakala ngokupolymerization kwe-lactic acid.Ngenxa yezidingo ezikhethekile zokuvikelwa kwemvelo okuphezulu kanye nokuhlanzeka okuphezulu kwezinkomishi zephepha, kuzomele kuthuthukiswe ukuthuthukiswa kobuchwepheshe be-PLA ne-PE ukuya endaweni ephakeme.Izinga lokudla ngokwalo lidinga ukunakwa, kodwa kanjalo nekhwalithi yezitsha ezisetshenziselwa ukudla neziphuzo.
