Me pēhea te tākai i te kawhe?
He tikanga te tīmatanga o te rā ki te kawhe hou kua oti te hanga mā te tini o te tangata o ēnei rā. E ai ki ngā raraunga mai i ngā tatauranga a YPAK, he "mea nui o te whānau" te kawhe puta noa i te ao, ā, e matapaetia ana ka piki ake i te $132.13 piriona i te tau 2024 ki te $166.39 piriona i te tau 2029, he tere tipu ā-tau o te 4.72%. Kei te puta ake ngā waitohu kawhe hou hei hopu i tēnei mākete nui, ā, i te wā kotahi, kei te tīmata hoki te whānau puku mai o ngā takai kawhe hou e hangai ana ki ngā ia whanaketanga.
Haunga te waihanga i ngā hua ahurei, me aro atu hoki ngā waitohu ki te pumau o ngā takai hei kukume mai i ngā kaihoko e aro nui ana ki te taiao. I roto i ngā kāwai katoa, ko ngā waitohu pīni kawhe tunua me ngā pīni kawhe huri kua ārahi i te tahuritanga ki te takai pumau, i te mea he puhoi ake te whanaketanga o ngā waitohu kawhe inamata nui te rahinga.
Mō te nuinga o ngā waitohu kawhe, e rua ngā huarahi hei neke ki te takai tauwhiro: ka taea e ēnei waitohu te whakakapi i ngā ipu karāhe taumaha tuku iho ki ngā putea whakakī anō, koinei ngā toa tuku o ngā takai pakari. He nui ngā whai huatanga o ngā takai māmā puta noa i te mekameka tuku, nā te mea ko te tikanga o ngā putea takai ngāwari he nui ake ngā takai ka taea te tuku i roto i ia ipu, ā, ko te mama o te taumaha ka whakaiti i ngā tukunga o te mekameka tuku. Heoi, ko te nuinga o ngā takai kawhe ngohengohe noa, nā te mea me noho hou tonu, he takai hiato, engari ka tūtaki ēnei ki te wero o te kore e taea te hangarua.
I te whai i te ia o ngā mahi, me āta whiriwhiri ngā kamupene kawhe i ngā takai pumau e pupuri ana i te reka me te whai kiko o te kawhe, ki te kore ka ngaro pea ā rātou kiritaki pono.
Te takai rauemi kotahi ārai teitei
He wā nui te whanaketanga o ngā paninga ārai mahi-teitei mō te umanga. Ko te pepa Kraft kua whakakikoruatia ki te PE, ki te pepa konumohe rānei, ka whakarato i ngā āhuatanga ārai e hiahiatia ana mō te tākai kawhe tunua me te kawhe whenua, engari kāore tonu e taea te whakatutuki i te āheinga hangarua e hiahiatia ana. Engari mā te whanaketanga o ngā papa pepa me ngā paninga ārai ka taea e ngā waitohu te tīmata ki te neke ki ngā tauira tākai e mau tonu ana, e taea ana te hangarua.
Kei te aro atu a YPAK, he kaihanga takai ngāwari o te ao, ki tēnei raruraru mā te whakamahi i tētahi takai whakarewa hou ka taea te hangarua, he mea hanga katoa ki te pepa. Ko te whāinga o tana rauemi monopolymer he hanga i te kirihou kia mau tonu. Nā te mea he kotahi te polymer i hangaia ai, ka taea te hangarua i te taha hangarau. Heoi, he uaua ki te whakatutuki i ōna painga katoa me te kore e haumi ki te hanganga hangarua tika.
Kua whakawhanakehia e YPAK tētahi raupapa monopolymer e kī ana he rite tonu ngā āhuatanga ārai. Nā tēnei i āwhina i tētahi waitohu kawhe i whakamahi i ngā kēne me ngā putea o roto ki te whakapai ake ki ngā takai kawhe papatahi-raro-kotahi rauemi ārai-teitei me ngā takirere kawhe. Nā tēnei i taea ai e te waitohu te karo i te hoko takai mai i ngā kaiwhakarato maha. Ka taea hoki e rātou te whakamahi i te mata takai katoa o te putea papatahi-raro mō te waitohu me te kore e herea e te rahi o te tapanga.
E rua tau te roa o te mahi a YPAK ki te whakawhanake i te takai hou e mau tonu ana te oranga. He hapa nui te tuku i tētahi kounga mō te hou o te kawhe, ā, kua pouri te nuinga o ā mātou kiritaki pono. Engari i mōhio mātou he mea kāore e manakohia te whakamahi tonu i ngā takai uaua ki te hangarua.
I muri i te wā roa e huri ana, ka kitea e YPAK te whakautu i roto i te LDPE #4.
He kirihou 100% te hanga o te putea a YPAK kia noho haumaru, kia hou hoki te kai kawhe. Ā, ka taea te hangarua anō i te putea. Ina koa, he LDPE #4 te mea hanga, he momo polyethylene iti te matotoru. Ko te nama "4" e tohu ana i tōna matotoru, ko te LDPE #1 te mea tino matotoru. I whakaitihia e te waitohu tēnei nama kia taea ai te whakaiti i tōna whakamahinga.
Kei te putea i hangaia e YPAK he waehere QR ka taea e ngā kaihoko te matawai ki tētahi whārangi e whakaatu ana me pēhea te hangarua, e whakatairanga ana i te ōhanga porowhita mā te whakaiti i ngā tukunga waro mā te 58%, te whakamahi i te 70% iti iho o ngā wahie pūmua hou, te 20% iti iho o ngā rauemi, me te whakanui ake i te whakamahinga o ngā rauemi hangarua ki te 70% ki te whakaritea ki ngā takai o mua.
He kaihanga mātou e tohunga ana ki te hanga i ngā putea tākai kawhe mō ngā tau neke atu i te 20. Kua noho mātou hei tētahi o ngā kaihanga putea kawhe nui rawa atu i Haina.
Ka whakamahia e mātou ngā takirere WIPF kounga teitei mai i Huiterangi hei pupuri i te hou o tō kawhe.
Kua whakawhanakehia e mātou ngā putea hoa-taiao, pērā i ngā putea wairākau me ngā putea hangarua, me ngā rauemi PCR hou rawa atu.
Koinei ngā kōwhiringa pai rawa atu hei whakakapi i ngā putea kirihou tuku iho.
He mea hanga tā mātou tātari kawhe maturuturu ki ngā rauemi Hapanihi, koinei te rauemi tātari pai rawa atu kei te mākete.
Kua tāpirihia mai tā mātou rārangi utu, tēnā tukuna mai te momo putea, te rauemi, te rahi me te rahinga e hiahiatia ana e koe. Kia taea ai e mātou te whakahua i ō utu.
