I te whakatinanatanga o ngā aukati kirihou puta noa i te ao, kei te rapu te iwi i ngā huarahi pai mō te taiao hei whakakapi i ngā taputapu kai kirihou whakakorekore. Kua tīmata te puta mai o ngā momo taputapu kai kirihou koiora ki te mākete hei huarahi pai mō te taiao hei whakakapi i ngā taputapu kai kirihou whakakorekore. He rite te āhua o ēnei taputapu kai kirihou koiora. Engari he aha ngā rerekētanga? I tēnei rā, me whakarite tātou i ngā taputapu kai kirihou koiora e rua e kitea whānuitia ana, arā, ko te CPLA Cutlery me te PSM Cutlery.
(1) Rauemi Mata
Ko te PSM he whakarāpopototanga mō te rauemi māngaro tipu, he rauemi ranu o te māngaro tipu me te whakakī kirihou (PP). Me whakamahi ngā whakakī kirihou hei whakapakari i te kapia māngaro kānga kia pai ai te mahi i te whakamahinga. Kāore he ōrau paerewa o te hanganga rauemi. Ka whakamahia pea e ngā kaihanga rerekē ngā rauemi he rerekē ngā ōrau o te māngaro mō te hanga. Ka rerekē pea te nui o te māngaro kānga mai i te 20% ki te 70%.
Ko te rauemi mata e whakamahia ana e mātou mō ngā taputapu kai CPLA ko te PLA (Poly Lactic Acid), he momo bio-polymer e ahu mai ana i te huka i roto i ngā momo tipu rerekē. Kua whakamanahia te PLA ka taea te whakawairakau me te pirau.
(2) Te Whakakotahitanga o te Wairākau
Ka taea te whakawairakau i ngā taputapu kai CPLA. Kāore ngā taputapu kai PSM e taea te whakawairakau.
Tērā pea ka karangahia e ētahi kaihanga ngā taputapu kai PSM he taputapu kai māngaro kānga, ā, ka whakamahia te kupu pirau-ora hei whakaahua i taua mea. Inaa, kāore e taea te whakawairakau i ngā taputapu kai PSM. Mā te whakamahi i te kupu pirau-ora me te karo i te kupu pirau-ora ka hē pea ki ngā kaihoko me ngā kaihoko. Ko te tikanga o te pirau-ora ko te pirau o tētahi hua, engari kāore e whakarato i tētahi mōhiohio mō te roa o te wā ka pirau katoa. Ka taea e koe te kī he pirau-ora ngā taputapu kai kirihou noa, engari tera pea ka roa ki te 100 tau ka pirau!
Kua whakamanahia ngā taputapu kai CPLA hei whakawairakau. Ka taea te whakawairakau i roto i ngā whare whakawairakau ahumahi i roto i ngā rā 180.
(3) Ātete Wera
Ka taea e ngā taputapu tapahi CPLA te ātete i te pāmahana tae atu ki te 90°C/194F, ko ngā taputapu tapahi PSM ia ka taea te ātete i te pāmahana tae atu ki te 104°C/220F.
(4) Ngāwari
He tino pakari, he mārō hoki te rauemi PLA, engari kāore i te ngāwari. He ngāwari ake te PSM i te rauemi PLA nā te mea kua tāpirihia te PP. Ki te pikohia e koe te kakau o te marau CPLA me te marau PSM, ka kite koe ka whati te marau CPLA, ka ngāwari ake ia te marau PSM, ā, ka taea pea te piko ki te 90° me te kore e whati.
(5) Ngā Kōwhiringa Whakamutunga o te Ora
He rerekē ki te kirihou, ka taea hoki te whakakore i te māngaro kānga mā te tahunga, ka puta he paoa kore paitini me te toenga mā ka taea te whakamahi hei tongi.
I muri i te whakamahinga, ka taea te whakakōhua i ngā taputapu kai CPLA ki roto i ngā whare whakakōhua ahumahi arumoni i roto i ngā rā 180. Ko ōna hua whakamutunga ko te wai, te hauhā waro, me te koiora matūkai hei tautoko i te tipu o ngā tipu.
He mea hanga ngā taputapu kai a MVI ECOPACK CPLA mai i ngā rauemi hou. Kua whakaaetia e te FDA mō te pa ki te kai. Kei roto i te huinga taputapu kai he marau, he maripi, me te pūnu. E tutuki ana i te ASTM D6400 mō te Whakakotahitanga.
Mā ngā taputapu kai pirau-koiora ka taurite te kaha, te ātete ki te wera me te ngāwari ki te whakawairakau e pai ana mō te taiao, ka pai te āhua o tō ratonga kai.
Ki te whakaritea ki ngā taputapu tuku iho i hangaia mai i te 100% kirihou parakore, ko ngā taputapu kai CPLA he mea hanga ki te 70% rauemi whakahou, he kōwhiringa pumau ake tēnei. He tino pai mō ngā kai o ia rā, ngā wharekai, ngā huihuinga whānau, ngā taraka kai, ngā huihuinga motuhake, te whakarite kai, te marena, ngā pāti me ētahi atu.
Kia pai tō kai me ā mātou taputapu kai tipu hei oranga mōu, hei oranga hoki mōu.
