Ahakoa kua pāngia ngā rauemi tākai whakapaipai e te mate urutā, kua paku iti iho tō rātou rongonui i ērā o ngā tau kua hipa, ā, kāore tonu e taea te aukati i ngā kaihoko o roto me tāwāhi ki te rapu hua hou, hangarau hou me te keri i ngā momo ahua.
He aha ngā hua o ngā au o te tau 2021?
Te mahi, te tiaki taiao me te ōhanga
I roto i te tukanga hoko hua a ngā kaihoko, he mea nui te takai hei whakatau mēnā ka hokona e ngā kaihoko ngā hua. Nō reira, kua whakahuatia hoki te hoahoa takai o ngā mea whakapaipai hei tūranga tino nui. He mea nui te rauemi me te mahi toi ki te whakaatu i te āhua o te takai hua.
Nā te mea ka taea e te rauemi karāhe te whakaatu pai ake i te taumata teitei o te hua, he maha ngā waitohu papai e whiriwhiri ana ki te whakamahi i ngā ipu karāhe, engari he mārama hoki ngā ngoikoretanga o ngā rauemi tākai karāhe. Nō reira, kia tutuki ai te taurite i waenga i te kakano me te ōhanga, ka whakamahia hoki e te maha o ngā kamupene te rauemi PETG i roto i te hanga ipu whakapaipai.
He rite te mārama o te PETG ki te karāhe, ā, he tata ki te matotoru o te karāhe, ka taea ai te hanga i te hua kia āhua matatau ake i te katoa, ā, i te wa ano he ātete ake i te karāhe, ā, ka taea e ia te urutau pai ake ki ngā hiahia whakahaere me te kawe waka o ngā hongere hokohoko ipurangi. I kī anō hoki ētahi atu kaihokohoko i uru atu ki tēnei whakaaturanga ka taea e te rauemi PETG te pupuri pai ake i te pumau o te ihirangi i te kiriaku (PMMA), nō reira he tino rapuhia e ngā kiritaki o te ao.
I tētahi atu taha, nā te pikinga ake o te mōhiotanga ki te tiaki taiao, he nui ake ngā kaihoko e hiahia ana ki te utu mō te utu nui o ngā hua e pai ana ki te taiao, ā, kua whakatapua e ngā kamupene whakapaipai ki tēnei. Nā te whanaketanga o te hangarau kua taea e ngā rauemi e pai ana ki te taiao te whakarere i te ariā, ā, kua tīmata ki te whakatinana i ngā tono arumoni. Kua puta mai he raupapa o ngā rauemi tiaki taiao PLA (i hangaia mai i ngā rauemi tipu hou, pērā i ngā rauemi mata māngaro i tangohia mai i te kānga me te manioka), e whakamahia whānuitia ana i roto i ngā takai kai me ngā whakapaipai. E ai ki tana kupu whakataki, ahakoa he nui ake te utu o ngā rauemi e pai ana ki te taiao i ērā o ngā rauemi noa, he mea nui tonu i runga i te uara ōhanga whānui me te uara taiao. Nō reira, he maha ake ngā tono i te raki o Ūropi me ētahi atu rohe.
He nui ake te utu o ngā rauemi PLA i ngā rauemi whānui. Nā te mea he hina, he pōuri hoki te rauemi taketake o te rauemi taketake, he iti iho te piri o te mata me te whakaaturanga tae o ngā rauemi takai tiaki taiao i ngā rauemi whānui. He mea tika kia kaha te whakatairanga i ngā rauemi tiaki taiao. Haunga te whakahaere utu, he mea tino nui hoki te whakapai ake i ngā tukanga.
Te aro o te motu ki te ataahua o ngā hua, te aro o tāwāhi ki te hangarau o ngā hua
He rerekē ngā hiahia o ngā waitohu whakapaipai o te motu me tāwāhi. "Ko ngā waitohu o te ao e aro nui ana ki te mahi toi me te mahi, ko ngā waitohu o te motu ia e aro nui ana ki te uara me te whai huatanga o te utu" kua noho hei whakaaro whānui. I whakamōhio ngā kaihokohoko rauemi tākai ki te ētita me whai ngā waitohu o te ao i ngā momo whakamātautau, pērā i te Whakamātautau Whakawhitiwhiti (arā, whakamahia he maripi Whakamātautau Whakawhitiwhiti hei tohu i te mata o te hua hei aromatawai i te piri o te peita), te whakamātautau maturuturu, me ētahi atu, hei tirotiro i te peita o te tākai hua, te piri, ngā whakaata, ngā rauemi, me ētahi atu, me te takai o ngā rauemi tākai, engari kāore e nui te hiahia o ngā kaihoko o te motu, he mea nui ake te hoahoa ātaahua me te utu tika.
Te whanaketanga o te hongere, e mihi ana te pakihi mōkihi ki ngā whai wāhitanga hou.
Nā te pānga o te Covid-19, kua hurihia e te nuinga o ngā rauemi tākai whakapaipai me te umanga tiaki kiri whakapaipai ngā hongere tuimotu hei whakatairanga me te mahi tuihono. He maha ngā kaiwhakarato kua whakatairanga i te tipu o ngā hoko mā te pāpāho ora tuihono, ā, nā tēnei hoki i nui ake ai te tipu o ngā hoko.
