Izinto ezibolayo ezibolayo izinto ezingahlukaniswa ngokuphelele zibe izinhlanganisela zamangqamuzana aphansi ngamagciwane (isb., amabhaktheriya, isikhunta, nolwelwe, njll.) ngaphansi kwezimo zemvelo zemvelo zesikhathi esifanele nesinokuboniswa.Njengamanje, zihlukaniswe ikakhulukazi izigaba ezine eziyinhloko: i-polylactic acid (PLA), i-PBS, i-polylactic acid ester (PHA) ne-polylactic acid ester (PBAT).
I-PLA ine-biosafety, i-biodegradability, izakhiwo ezinhle zemishini kanye nokucutshungulwa kalula, futhi isetshenziswa kakhulu ekupakishweni, kwendwangu, amafilimu epulasitiki ezolimo kanye nezimboni ze-polymer ze-biomedical.
I-PBS ingasetshenziswa ekufakweni kwefilimu, i-tableware, izinto zokupakisha ezinegwebu, amabhodlela asetshenziswa nsuku zonke, amabhodlela emithi, amafilimu ezolimo, izinto ezikhipha kancane izibulala-zinambuzane kanye nezinye izinkambu.
I-PHA ingasetshenziswa emikhiqizweni elahlayo, izingubo zokuhlinzwa zemishini yezokwelapha, izikhwama zokupakisha kanye ne-composting, ama-sutures ezokwelapha, amadivaysi okukhanda, amabhandeshi, izinaliti zamathambo, amafilimu aphikisana nokunamathela kanye nama-stents.
I-PBAT inezinzuzo zokusebenza okuhle kokwenza ifilimu nokuvunguza kwefilimu okulula, futhi isetshenziswa kabanzi emikhakheni yamafilimu okupakisha alahlwayo namafilimu ezolimo.
