Ko te waikawa Polylactic (PLA) he pūmua kua whakakotahitia ki te waikawa lactic hei rauemi matua, he mea taketake katoa, ā, ka taea te hanga anō. Kāore he parahanga i roto i te tukanga whakaputa o te waikawa polylactic, ā, ka taea te pirau i te hua kia pai ai te horapa i roto i te taiao, nō reira he rauemi pūmua matomato tino pai. Ko te waikawa Polylactic ((PLA)) he momo rauemi pirau hou mōngā hua kirihou, Tānga 3DKo te māngaro i tangohia mai i ngā rauemi tipu hou (pērā i te kānga) ka hangaia hei waikawa miraka mā te whakapūkara, kātahi ka hurihia hei waikawa polylactic mā te hanga pūmua.

He tino pai te pirau o te waikawa poly (lactic acid), ā, ka taea te whakangaro katoa e te 100% o ngā moroiti i roto i te oneone i roto i te tau kotahi i muri i te whakarērea, ka hua ake he hauhā waro me te wai, ā, kāore he parahanga ki te taiao. Ka tutuki pai te "nō te taiao, nō te taiao". E ai ki ngā pūrongo pāpāho, ka piki te pāmahana o te ao ki te 60 ℃ i te tau 2030. Kei te tahuna tonu ngā kirihou noa, ka tukuna he nui o ngā hau kati kōtuhi ki te rangi, ko te waikawa polylactic ka tanumia ki roto i te oneone hei pirau. Ka haere tika te hauhā waro hua ki roto i ngā mea rauropi o te oneone, ka mimitihia rānei e ngā tipu, kāore e tukuna ki te rangi, kāore hoki e puta he Pānga Kati Kōtuhi.

He pai te Poly (waikawa lactic) mō ngā momo tikanga tukatuka pēnei i te pupuhi me tewhakakoi werohangaHe māmā te tukatuka, ā, he whānui te whakamahinga. Ka taea te whakamahi hei tukatuka i ngā momo ipu kai katoa, i ngā kai kua tākaihia, i ngā pouaka tina kai tere, i ngā papanga kore-whatu, i ngā papanga ahumahi me ngā papanga ā-iwi mai i te ahumahi ki te whakamahinga ā-iwi. Kātahi ka tukatukahia hei papanga ahuwhenua, hei papanga tiaki hauora, hei kakahu taratara, hei hua horoi tinana, hei papanga ārai-iraira o waho, hei kakahu tēneti, hei moenga papa me ērā atu mea, he tino whai hua te tirohanga mākete. Ka kitea he pai ōna āhuatanga ā-pūkaha me ā-tinana.

He rite tonu ngā āhuatanga ā-tinana taketake o te waikawa polylactic (PLA) me ngā kirihou hanga matū hinu, arā, ka taea te whakamahi whānuitia hei hanga i ngā momo hua tono. He pai hoki te kanapa me te mārama o te waikawa polylactic, he rite ki te kiriata i hangaia mai i te polystyrene, ā, kāore e taea te whakarato e ētahi atu hua pirau.
