Kāore koe i te tino mōhio ko tēhea momo mēra te mea pai mō tō waitohu? Anei ngā mea me mōhio e tō pakihi mō te whiriwhiri i waenga i te noissue Recycled, Kraft, me teNgā Mēra Whakakotahi.

Ko te takai wairākau he momo tākai e whai ana i ngā mātāpono o te ōhanga porowhita.

Engari ko te tauira rārangi 'tango-hanga-para' tuku iho e whakamahia ana i roto i te hokohoko, kua hangaia ngā takai wairākau kia tukuna atu i runga i te huarahi tika, kia iti ake ai te pānga ki te ao.

Ahakoa he rauemi e mōhiotia ana e te tini o ngā pakihi me ngā kaihoko te takai wairākau, kei te mau tonu ētahi hē whakaaro mō tēnei momo takai hoa-taiao.

Kei te whakaaro koe ki te whakamahi i ngā takai para i roto i tō pakihi? He mea pai kia mōhio koe ki ngā mea katoa e taea ana mō tēnei momo rauemi kia taea ai e koe te kōrero me te whakaako i ngā kiritaki ki ngā huarahi tika hei whakakore i muri i te whakamahinga. I roto i tēnei aratohu, ka ako koe:

He aha ngā kirihou koiora
He aha ngā hua tākai ka taea te whakakōhua
Me pēhea te hanga wairākau mō te pepa me te kātene
Te rerekētanga i waenga i te pirau-koiora me te pirau-pūtake
Me pēhea te kōrero māia mō ngā rauemi whakawairā.
Kia tīmata tātou!

He aha te takai wairākau?
Ko te takai wairākau he takai ka pakaru noa iho ina waiho ki te taiao tika. He rerekē ki te takai kirihou tuku iho, he mea hanga mai i ngā rauemi rauropi ka pakaru i roto i te wā tika, ā, kāore e waiho he matū paitini, he matū kino rānei. E toru ngā momo rauemi e taea ai te hanga takai wairākau: pepa, kāri, kirihou koiora rānei.

Ako atu mō ētahi atu momo rauemi takai porowhita (ka taea te hangarua me te whakamahi anō) i konei.

He aha ngā kirihou koiora?
Ko ngā kirihou koiora he kirihou e ahu mai ana i te koiora (he mea hanga mai i tētahi rauemi whakahou, pērā i ngā huawhenua), he pirau-ora (ka taea te pakaru māori) he whakakotahitanga rānei o ngā mea e rua. Ka āwhina ngā kirihou koiora ki te whakaiti i tō tātou whakawhirinaki ki ngā wahie pūmua mō te hanga kirihou, ā, ka taea te hanga mai i te kānga, te pīni soya, te rakau, te hinu tunu kai kua whakamahia, te rimurimu, te tō me te maha atu. Ko tētahi o ngā kirihou koiora e whakamahia whānuitia ana i roto i ngā takai ko te PLA.

He aha te PLA?

Ko te PLA he tikanga mō te waikawa polylactic. He kirihou wairākau ka taea te whakawairakau te PLA, i ahu mai i ngā tangohanga tipu pēnei i te māngaro witi, te tō rānei, ā, he kore-waro, ka taea te kai, ā, ka pirau hoki. He huarahi tūturu ake tēnei hei whakakapi i ngā wahie pūmua, engari he rauemi hou anō hoki me tango mai i te taiao. Ka memeha katoa te PLA ina pakaru, kaua e pakaru hei kirihou moroiti kino.

Ka hangaia te PLA mā te whakatipu i tētahi hua tipu, pērā i te kānga, kātahi ka wahia hei māngaro, hei pūmua me te muka hei hanga i te PLA. Ahakoa he iti ake te kino o tēnei tukanga tango i te kirihou tuku iho, e hangaia ana mā roto i ngā hinu pūmua, he nui tonu ngā rauemi e whakamahia ana i tēnei tukanga, ā, ko tētahi whakahē mō te PLA ko te tango i te whenua me ngā tipu e whakamahia ana hei whāngai i te tangata.
