Mā tēnei ka mārama koe ki ngā putea tākai pirau-koiora!
I te mea ka nui haere ngā whenua e aukati ana i ngā pēke kirihou, kei te nui haere te whakamahinga o ngā pēke pirau-koiora i roto i ngā ahumahi. He mea e kore e taea te karo te tiaki i te taiao. He puna kōrero kei reira e taunaki ana kia whakamahia ngā pēke kirihou pirau-koiora? He aha ngā hua ka taea te whakamahi i ngā pēke kirihou pirau-koiora? Ki taku whakaaro koinei te mea e hiahia ana te nuinga o ngā kaihoko e tono ana i ngā whakaritenga pēke kirihou pirau-koiora katoa kia mōhio. I tēnei rā, OK te whakaputanga tākai o ngā pēke kirihou pirau-koiora
1. He aha te takai pirau-koiora?
Ko te pēke kirihou pirau-koiora he momo pēke kirihou ka taea te whakangaro katoa i te wai, te hauhā waro me ētahi atu ngota iti. Ko te pūtake matua o tēnei rauemi pirau ko te waikawa polylactic (PLA), i tangohia mai i te kānga me te manioka. Ko Planet (PLA) he momo rauemi hou e ahu mai ana i te koiora me te rauemi pirau-koiora hou. I muri i te whakapūkara o te hukahuka me ētahi momo hei whakaputa waikawa lactic tino parakore, ka hangaia te poly (waikawa lactic) me te taumaha ngota motuhake mā te tikanga hanga matū, kātahi ka whiwhihia te hukahuka mā te saccharification. He pai te pirau-koiora o tēnei hua, ā, ka taea te whakangaro katoa e ngā moroiti taiao i muri i te whakamahinga hei whakaputa hauhā waro me te wai, e kore e whakapoke i te taiao i muri i te whakamahinga. He tino painga ki te tiaki taiao, ā, e kiia ana he rauemi hoa taiao.
I tēnei wā, ko te rauemi koiora matua o ngā pēke kirihou pirau he mea hanga mai i te PLA + PBAT, ka taea te pirau katoa hei wai me te hauhā waro i roto i te 3-6 marama i raro i te tikanga whakamomona (60-70 nekehanga). Kāore he parahanga ki te taiao. He aha i tāpirihia ai te PBAT? Ko te PBAT he copolymer o te waikawa adipic, 1, 4-butanediol me te waikawa terephthalic, he polymer aliphatic me te kakara pirau katoa i hangaia e te matū. He tino ngāwari te PBAT, ā, ka taea te whakamahi mō te extrusion kiriata, te pupuhi pokepoke, te paninga extrusion me ētahi atu tukanga pokepoke. Ko te ranunga o te PLA me te PBAT kua hangaia hei whakapai ake i te pakari, te pirau koiora me te hanganga o te PLA.
2. Kei hea ngā kaihanga o ngā putea pirau-koiora he ingoa pai tō rātou?
I roto i te mara o ngā pēke kirihou pirau-ora, kua hangaia he mīhini pupuhi kiriata motuhake, he mīhini tā, he mīhini tapahi pēke, he mīhini hangarua para, me ngā momo raina whakaputa pakari mō ngā pēke kirihou pirau-ora. Ko ngā hua e kapi ana i ngā pēke koti, ngā pēke para, ngā pēke ringa, ngā pēke kākahu, ngā pēke taputapu, ngā pēke whakapaipai, ngā pēke kai, ngā pēke kāri, ngā pēke pepa kraft/pLA, me ētahi atu, he kounga pumau, he pai te whakaputa, he tino pai te tā, he ātete makuku, he ātete poka, he kore paitini, he pai te hiri, he pai te totoro, he pai te kakano, he tiaki taiao.
He pai te takai e piri ana ki te ariā o te tiaki taiao, ā, e whakapau kaha ana ki te whanaketanga tauwhiro o te taiao, he pai te whakawhanake mō te umanga takai me te whakarato kai mō ngā rauemi me ngā hua pirau-katoa. He nui te wheako ki te umanga takai, ā, e aro ana ki te whakarōpūtanga para, e whakatairanga ana i te whakamahinga anō o ngā rauemi, ā, e kaha ana ki te whakawhanake i ngā hua pirau-katoa kounga-kai.
3. He aha ngā hua ka taea te whakamahi i ngā putea pirau-koiora?
He whānuitia te whakamahinga o ngā pēke kirihou pirau-ora i roto i ngā ahumahi hāte, whatu, kākahu, kakahu, whatu, kai, taputapu, hikohiko, whakapaipai me ētahi atu ahumahi. He maha ngā hoahoa hiri o ngā pēke kirihou pirau-ora, pērā i te wheua piri, te reti, te rīpene, me ētahi atu, ā, he pepa te mea e honoa ana ki ngā pēke kirihou pirau-ora, ka taea te whakapiko i te okana o raro. Ināianei, kei te uru atu ngā pēke kirihou pirau-ora ki ngā āhuatanga katoa o te ao, ā, he maha ngā momo kāhua; ā, i te heke mai, ka noho ngā pēke kirihou pirau-ora hei hua tino nui o te ahumahi tākai.
