O ato fa'apalapala fa'aleagaina o lona uiga e mafai ona fa'aleagaina, ae mafai ona vaevaeina le fa'aleagaina i le "fa'aleagaina" ma le "fa'aleagaina atoatoa".
O le faʻaleagaina o vaega e faʻatatau i le faʻaopoopoga o nisi faʻaopoopoga (e pei o le masoa, fetuutuunai masoa poʻo isi cellulose, photosensitizers, biodegradants, ma isi) i le taimi o le gaosiga o le gaosiga e faʻamautu ai.
A maeʻa ona paʻu, e sili atu ona faigofie le faʻaleagaina o palasitika i le siosiomaga masani.
Aofa'i fa'aleaga o lona uiga o mea palasitika uma e fa'aleagaina i le vai ma le carbon dioxide. O mea autu autu o lenei mea faʻaleagaina atoatoa e gaosia i le lactic acid (sana, manioka, ma isi), o le
PLA. O le Polylactic acid (PLA) o se ituaiga fou o mea ola faʻavae ma faʻafouina mea faʻaola. O meafaitino mata masoa e saccharified ina ia maua ai le kulukose, ona fa'afefeteina lea e le kulukose ma nisi galu.
E liua i le lactic acid maualuga-mama, ona faʻapipiʻiina lea o se vailaʻau polylactic mamafa mole e ala i le faʻaogaina o vailaʻau. E lelei le biodegradability ma e mafai ona faʻaogaina e microorganisms i le lalolagi faʻanatura.
E matua leaga lava i lalo o nisi tulaga ma iu ai ina maua mai le carbon dioxide ma le vai e aunoa ma le faaleagaina o le siosiomaga. E aoga tele lenei mea i le puipuiga o le si'osi'omaga ma ua fa'ailoaina o se mea fa'alesiosiomaga. I le taimi nei, ato fa'apipi'i e fa'amama atoatoa
O le mea autu o meaola faʻavae e aofia ai le PLA + PBAT, lea e mafai ona faʻaumatia atoa i le vai ma le carbon dioxide i le 3-6 masina i lalo o le tulaga o le faapalaga (60-70 tikeri), e le faʻaleagaina ai le siosiomaga.
Aisea e faaopoopo ai le PBAT Shenzhen Jiuxinda iinei e taʻu atu ia te oe o le PBAT o se kopi o le dicarboxylic acid, 1,4-butanediol, ma le terephthalic acid. O se ituaiga e mafai ona pala.
O se polymer aromatic aliphatic synthesized, PBAT e sili ona fetuutuunai ma e mafai ona faʻaaogaina mo le faʻauluina o ata, faʻafefeteina, faʻapipiʻi faʻapipiʻi ma isi gaioiga faʻapipiʻi. PLA ma PBAT
O le fa'amoemoega o le fa'afefiloi o le fa'aleleia atili lea o le malosi o le PLA, fa'aleagaina ma le fa'aogaina o le fa'agasolo. E le fetaui le PLA ma le PBAT, o lea la o le filifilia o se mea e fetaui lelei e mafai ai ona faʻaalia le faʻatinoga o le PLAfaaleleia.
