Ko te waikawa Polylactic (PLA) he momo rauemi pirau-koiora hou, he mea hanga mai i ngā rauemi mata māngaro i whakaarohia e ngā tipu hou (pērā i te kānga, te manioka, me ētahi atu). Ka whakakoitia te rauemi mata māngaro kia whiwhi ai i te hukahuka, kātahi ka whakapūpūtia mai i te hukahuka me ētahi momo hei whakaputa i te waikawa lactic tino parakore, kātahi ka whakamahia te tikanga hanga matū hei hanga i te waikawa polylactic me te taumaha ngota. He pai te pirau-koiora, ā, ka taea te pirau katoa e ngā moroiti i roto i te taiao i raro i ngā āhuatanga motuhake i muri i te whakamahinga, ā, ka mutu ka puta he hauhā waro me te wai, me te kore e whakapoke i te taiao, he tino painga mō te tiaki i te taiao, ā, e mōhiotia ana he rauemi hoa-taiao.
He pai te pumau o te waikawa polylactic i te wera, ko te pāmahana tukatuka he 170~230℃, ā, he pai te ātete ki te whakarewa. Ka taea te tukatuka i roto i ngā momo huarahi, pērā i te extrusion, te miro, te totoro biaxial, me te werohanga pupuhi. Haunga te pirau-koiora, he pai te hototahitanga koiora o ngā hua i hangaia mai i te waikawa polylactic, te kanapa, te mārama, te ātete ki te pa ki te ringa me te wera, tae atu ki ētahi ātete ki te huakita, te ātete ki te mura me te ātete ki te UV, nō reira he tino whai hua. He whānuitia te whakamahinga hei rauemi tākai, hei muka me te kore-whatu, me ētahi atu, e whakamahia ana i tēnei wā i roto i ngā kākahu (ngā kākahu o roto, ngā kākahu o waho), te ahumahi (hanga, ahuwhenua, ngahere, hanga pepa) me ngā mara hauora me te hauora.
