Zipangizo zomwe zimawonongeka ndi zinthu zomwe zimatha kugawidwa kwathunthu kukhala zinthu zochepa zamamolekyu ndi tizilombo toyambitsa matenda (monga mabakiteriya, bowa, ndi algae, ndi zina zotero) pansi pa nyengo yachilengedwe yoyenera komanso yowonekera. Pakadali pano, zimagawidwa m'magulu anayi akuluakulu: polylactic acid (PLA), PBS, polylactic acid ester (PHA) ndi polylactic acid ester (PBAT).
PLA ili ndi chitetezo chachilengedwe, kuwonongeka kwachilengedwe, mphamvu zabwino zamakanika komanso kukonza kosavuta, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale opaka, nsalu, mafilimu apulasitiki aulimi komanso mafakitale a polima azachipatala.
PBS ingagwiritsidwe ntchito mu filimu yopaka, mbale zophikira patebulo, zipangizo zopaka thovu, mabotolo ogwiritsidwa ntchito tsiku ndi tsiku, mabotolo a mankhwala, mafilimu a zaulimi, feteleza wophera tizilombo zomwe zimamasula pang'onopang'ono zinthu ndi zina.
PHA ingagwiritsidwe ntchito mu zinthu zotayidwa, zovala zochitira opaleshoni za zipangizo zachipatala, matumba opakira ndi opaka manyowa, zomangira zachipatala, zipangizo zokonzera, mabandeji, singano za mafupa, mafilimu oletsa kumatira ndi ma stenti.
PBAT ili ndi ubwino wokhala ndi mawonekedwe abwino opangira filimu komanso kupukutira filimu mosavuta, ndipo imagwiritsidwa ntchito kwambiri m'magawo a mafilimu opaka zinthu zotayidwa ndi mafilimu a zaulimi.
