Izinto ezibolayo zizinto ezinokuqhekeka ngokupheleleyo zibe ziikhompawundi eziphantsi zeemolekyuli ziintsholongwane (umz., iibhaktheriya, iifungi, kunye ne-algae, njl.njl.) phantsi kweemeko zendalo zendalo ezifanelekileyo nezibonakalayo. Okwangoku, zahlulwe ngokubanzi kwiindidi ezine eziphambili: i-polylactic acid (PLA), i-PBS, i-polylactic acid ester (PHA) kunye ne-polylactic acid ester (PBAT).
I-PLA inokhuseleko lwezinto eziphilayo, iyabola, ineempawu ezilungileyo zoomatshini kwaye kulula ukuyilungisa, kwaye isetyenziswa kakhulu kwiipakethe, kwimpahla yelaphu, kwiifilimu zeplastiki zezolimo nakwimizi-mveliso yepolymer yezonyango.
I-PBS ingasetyenziswa kwifilimu yokupakisha, izitya zetafile, izixhobo zokupakisha zefoam, iibhotile ezisetyenziswa imihla ngemihla, iibhotile zamayeza, iifilimu zezolimo, isichumiso sezinambuzane esikhupha izinto kancinci kunye nezinye iindawo.
I-PHA ingasetyenziswa kwiimveliso ezilahlwayo, iilokhwe zotyando zezixhobo zonyango, iingxowa zokupakisha nezokufaka umgquba, izikhongozeli zonyango, izixhobo zokulungisa, iibhandishi, iinaliti zamathambo, iifilimu zokulwa nokunamathela kunye neestenti.
I-PBAT ineengenelo zokusebenza kakuhle kwefilimu kunye nokuvuthuza ifilimu ngokulula, kwaye isetyenziswa kakhulu kwiinkalo zeefilimu zokupakisha ezilahlwayo kunye neefilimu zezolimo.
