PLA Kirihou Pirau-koiora, PLA Whakakikoruatia, putea inu pirau-tū

Ko ngā mātāpono o te pirau o ngā kirihou pirau-ora kua wehea ki te pirau-ataata, te pirau-ora me te pirau-wai, me ētahi atu. I tēnei wā, ko te pirau-pūmua i roto i te āhua whakamomona te tikanga matua. Ko te māngaro te nuinga o te mea hanga. I roto i te āhua whakamomona, ka wehea ki te hauhā waro me te wai e ngā pūmua, ka whakapai ake i te momona o te oneone, ka whakatau hoki i te raruraru o te parahanga mā i te pūtake.
Ko te waikawa polylactic (PLA) he momo rauemi pirau hou i hangaia mai i ngā rauemi mata māngaro i whakaarohia e ngā rauemi tipu hou pēnei i te kānga. He pai te pirau o tēnei rauemi, ā, ka taea te pirau katoa e ngā moroiti i roto i te taiao i muri i te whakamahinga, ā, ka puta he hauhā waro me te wai, me te kore e whakapoke i te taiao, he mea tino whai hua ki te tiaki i te taiao, ā, e mōhiotia ana he rauemi hoa taiao.
Ko ngā pēke ngongo e whakamahia whānuitia ana hei tākai i ngā wai, pērā i ngā wai hua, ngā inu, ngā hopi horoi, te miraka, te miraka pīni soya, te ranu pīni soya, me ētahi atu. I te mea kua mārama te nuinga o ngā kaihoko ki ngā painga o te tākai ngāwari ngongo e te tini, me te kaha haere tonu o te mōhiotanga tiaki taiao pāpori, ka noho hei ia te whakamahi i te tākai ngāwari ngongo hei whakakapi i ngā oko, me te whakamahi i te tākai ngāwari ngongo hei whakakapi i ngā tākai ngāwari tuku iho kāore e taea te hiri anō. Ko te painga nui o ngā pēke ngongo i ngā momo tākai noa ko te ngāwari ki te kawe. Ka taea te whakauru ngāwari i te pēke waha ki roto i te peke tuara, i te pōke rānei, ā, ko te whānuitanga o te pakihi o tā mātou wheketere he āhuatanga o te kanorau me te whakaiti i ngā mea kei roto.
Ka taea e ngā rauemi pirau te whakaiti i ngā raruraru parahanga taiao. He nui te takoha ki te tiaki i te taiao.
Ehara i te mea ka taea anake te whakaiti i ngā tukunga hau kino, engari ka whakapai ake hoki i te oneone hei tongi rauropi. Nō reira, me whanake te whanaketanga o ngā putea pupuhi pirau e pai ana mō te taiao kia pai ake ai te whakatutuki i ngā hiahia whānui o te ao tiaki taiao. Ka taea e ngā putea pupuhi pirau taiao te whakaiti me te aukati i te parahanga taiao, engari me whakawhanake tonu te hangarau whakaputa me te rongonui me te tono, he mea nui ki te whakamahinga pūngao me te tiaki taiao.
