Pouaka Pepa me te Kirihou: Ko tēhea te Takai Tauwhiro Pai ake mō te Tango me te Tuku Kai

Kupu Whakataki

Ina whakaarohia ngā kōwhiringa mō te takai kai hei tuku, hei tango rānei, ka tātarihia e ngā pakihi te pai o te noho hou o te kai i roto i te ipu. I roto i te tukanga, ka kore e tūhuratia e rātou ngā kōwhiringa e wātea ana, ā, ka warewarehia te taha pumau. Ko te tikanga, e rua ngā kōwhiringa mō ngā pakihi kai: ngā pouaka pepa me ngā takai kirihou. He mea nui kia whiriwhiria he kōwhiringa e tuku ana i te utu tika, te kanorau, te kounga, me te hoahoa e pai ana ki te taiao.

E ai ki te US Environmental Protection Agency (EPA), neke atu i te 28% o ngā para totoka ā-tāone (MSW) katoa i te United States anake ko ngā ipu me ngā takai. E ai ki a Frontiers in Food Science and Technology, tata ki te 50% o ngā para takai katoa ko ngā takai kai me ngā inu. Nō reira, he āwangawanga nui ngā takai mō ngā kai tango me ngā kai e tukuna ana, nā te mea ko te nuinga o ēnei para ka mutu ki ngā whenua ururua me ngā moana, he pānga nui tēnei ki ngā mea ora o te moana, ka whai wāhi ki ngā tukunga waro, te whakamahinga rauemi, me te parahanga.

Nā ēnei raruraru, kei te whakarite ngā pakihi i a rātou anō ki ngā whāinga e pai ana ki te taiao, me te kore e whakararu i te whai huatanga o ngā kai wera, ngā kai hinuhinu rānei. Kei te tumanako ngā kaihoko me ngā wharekai ki te tākai pumau kei roto i tēnā ko ngā āhuatanga matua pēnei i te pirau-ora, te hangarua, me te whai hua o te pūngao. Nō reira, ahakoa he pakihi koe, he rangatira wharekai rānei, ā, kei te tumanako koe ki te neke i tō pakihi ki te takai pumau me te pupuri i te hou o te kai, ka whakatauritehia e tēnei tuhinga ngā painga me ngā huakore o ngā momo e rua hei āwhina i a koe ki te whakahāngai i tō pakihi ki te taiao-hoa me te kore e whakararu i te kounga o te kai.

Te Tapuwae Taiao o te Takai Kirihou

I tēnei wāhanga o te tuhinga, ka matapakihia e mātou te pānga ki te taiao o ngā takai kirihou me ngā āhuatanga e whai wāhi ana ki tōna tapuwae waro nui, mai i te tango wahie pūmua ki tōna oranga roa i roto i ō tātou moana.

Te Whakawhirinakitanga ki te Wahie Pūmua me ngā Tukunga

He maha ngā raruraru taiao e pā ana ki ngā takai kirihou, ā, ko tētahi o aua raruraru ko te hanga takai kirihou me hanga ngā polymer pēnei i te polyethylene, te PET rānei, e tino whakawhirinaki ana ki ngā rauemi kāore e taea te whakahou. He nui ngā hiahia pūngao mō te tukanga whakaputa e pā ana ki te umanga hinu matū:

• Te Whakamahinga Hinu: E ai ki te World Economic Forum, e 4% ki te 8% o te hinu hanga o te ao e pau ana i te umanga kirihou ia tau hei whakatutuki i ngā whakaritenga pūngao mō te hanga kirihou.
• Ngā Hau Kākāriki: I ia wāhanga o te hanga kirihou, mai i te tango me te whakamahine ki te pakaru me te whakapūhui, ka tukuna ngā hau kākāriki e whakapoke ana i te āhuarangi.
• Te Utu Waro: Ahakoa he mama te kirihou, ka whakaiti i ngā tukunga waro e puta mai ana i te kawe waka, he nui ake te nama waro tuatahi o te tango wahie pūmua mō te hanga kirihou i te hauhake rakau ka taea te whakahou.

Te Pumau o te Parahanga

Ko tētahi o ngā raruraru nui o te kirihou ko tōna roa o te ora. Ka pirau ngā kirihou kore-pirau hei kongakonga iti e kiia nei ko ngā kirihou moroiti ka roa mō te 400 ki te neke atu i te 1,000 tau. Nā tēnei ka mutu ēnei kongakonga ki ngā whenua ururua, ki ngā moana rānei, ka mōrearea te kanorau koiora me ngā mea ora o te moana, ā, ka noho hei wāhanga o te mekameka kai.

Ngā Wero o te Mutunga o te Oranga

Kei te mahi tonu ngā kaipūtaiao me ngā kairangahau ki te hangarua i ngā kirihou, engari kei te iti tonu ngā auau hangarua. Kei raro nei ētahi o ngā raraunga me ngā tatauranga e whakaatu ana i te whai wāhi a te whakamahinga o te kirihou ki te waihanga i tētahi raruraru whakahaere para.

• Ngā Auau Hangarua Iti: E ai ki te EPA, i te US, ko te auau hangarua mō ngā kirihou kei te 9% pea, ko te tikanga ko te toenga 91% ka mutu ki ngā whenua ururua, ki ngā moana rānei.
• Te Tahunga Paitini: Hei whakakore i ēnei kirihou, tata ki te 16% o ngā para kirihou o te ao ka tahuna ki te aroaro o te marea, ki roto rānei i ngā oumu tahu, ka puta ake ngā tukunga paitini pērā i ngā taiokini me ngā hua tahunga kāore anō kia oti pērā i te hauota waro me te pungarehu.

Te Tapuwae Taiao o te Tākai Pepa

E kiia ana ko te tākai pepa te otinga pumau mō te tākai mō ngā kai tango me ngā kai tuku. I tēnei wāhanga o te tuhinga, ka tūhuratia e mātou he aha te mea e pai ai hei otinga pumau mō te raruraru tākai, me ōna ngoikoretanga.

Te Pūtake Whakahou me te Ngongo Waro

Ko ngā rauemi mata mō te takai pepa i ahu mai i ngā pūtake koiora, pērā i te penupenu rakau, te pūkohu, te bagase rānei. I te mea ka tipu ngā rākau me ngā tipu mā te mimiti i te CO2, ka iti ake ngā tukunga kupenga mēnā ka ahu mai ngā rauemi mata i ngā whakahaere tiwhikete tauwhiro pērā i te FSC (Forest Stewardship Council). Ko te tikanga he pai ake ki ngā kaihanga te whakamahi i te pūkohu mō te takai pepa nā te mea ka tere te tipu i roto i te 6 ki te 8 marama, ā, he tere ake te tere mimiti waro ki te whakaritea ki te rakau tuku iho.

Teitei o te Hangarua me te Pirau-koiora

Ko tētahi o ngā painga matua o te takai pepa i runga i te takai kirihou ko te poto ake o te wā pirau, me te tere hangarua teitei ake. Ka taea e te pepa te pirau i roto i ngā wiki, ā, i te ao whānui, he nui ake ngā reiti hangarua pepa, ā, e ai ki te American Forest & Paper Association, tata ki te 68% te reiti o te hangarua pepa i te US. Ko ētahi o ngā painga ko:

• Penapena Pūngao: E 40% te iti iho o te pūngao e pau ana i te hangarua pepa ki te whakataurite ki te hanga pepa hou mō ngā takai.
• Te Pūmanawa Whakamahi Anō: Ka taea te hangarua me te whakamahi anō i ngā muka pepa e 5 ki te 7 ngā wā i mua i te poto rawa hei here.
• Te Hurihanga o te Parapara: Nā te nui o ngā tere hangarua, ka ārai te wā pirau poto i te waipuke o te parapara

Te Kaha o ngā Rauemi me te Auahatanga

Ko tētahi o ngā raruraru nui mō te hanga pepa ko te nui o te wai e hiahiatia ana i roto i te tukanga tuku iho. Ki te whakaritea ki te hanga kirihou, e whā ngā wā ka nui ake te wai e hiahiatia ana mō te hanga pepa i te hanga kirihou. Heoi, nā ngā auahatanga hangarau, kei te mahi tonu ngā kaipūtaiao me ngā kairangahau ki te whakaiti i te whakamahinga wai mō te hanga pepa. Kei roto i ēnei auahatanga ko te whakamahi i te muka whakarewa, e whakamahi ana i ngā toenga ahuwhenua hei whakaiti i te whakangaromanga o ngā ngahere me te whakamahinga wai. Hei tāpiri, kei te hangarua anō ngā mira hanga pepa i te wai, ā, kua iti ake te wai māori e inumia ana.

Te Whakataurite i te Oranga Tonutanga: Pepa me te Kirihou

I tēnei wāhanga o te tuhinga, ka whakatauritea e mātou he ripanga i waenga i ngā takai pepa me ngā takai kirihou hei āwhina i a mātou ki te whakatau ko tēhea te kōwhiringa takai pai rawa atu mō te pupuri i te kai kia hou, kia hauora, kia pumau hoki.

Ngā Tātaitanga Tapuwae Waro

He whārite, he tātai rānei e mōhiotia ana ko te whārite mō te pānga katoa e whakamahia ana hei tatau i te tapuwae waro o te whakaputa i tētahi hua. Ka taea te whakamahi i tēnei whārite hei tatau i te tapuwae waro mō te whakaputa kirihou me te pepa, hei āwhina i a tātou i roto i tā tātou whakatairite hei āwhina i a tātou ki te whakatau ko tēhea te kōwhiringa he pai ake te oranga tonutanga.

• Whārite: (Tauwehenga Tukunga × Rahinga) + Utu Whakakorenga

Tukunga Waro Kirihou me te Pepa

Mā te hanga i te 1kg o te kirihou ka puta he 6kg o ngā poke (tauwehenga tukunga). He ōwehenga 1:6 tēnei. Nō reira, ki te hanga i te 1 kg o te kirihou mō te takai, ko ngā poke e puta he 6 ngā wā te taumaha o te kirihou, ā, he nui te utu mō ngā poke o te kirihou. Mā te hanga i te 1kg o te pepa ka puta he 0.5kg (tauwehenga tukunga) o ngā poke pērā i te CO2 _. He iti iho tēnei i te kirihou mō te taumaha ōrite o te rauemi.

Te Utu Whakakorenga

Ko te utu whakakorenga kua whakahuatia i roto i te whārite e whakaatu ana i te pānga i puta mai i te kirihou, i te pepa rānei i muri i te maka atu. He tino iti te utu whakakorenga o te pepa nā te mea he ngāwari te pirau, te hangarua rānei. I tētahi atu taha, ka taea e te kirihou te noho ki ngā whenua ururua, ki ngā moana rānei mō ngā rautau, ina tahuna rānei ka tukuna he nui o ngā poke, ka nui ai ngā utu whakakorenga.

Te Hopu

He iti ake te pānga o te kawe kirihou ki ngā tukunga hau ki te pepa. I roto i tētahi pouaka he rite te rahi, ka taea te whakauru i te nui o te kirihou, engari he nui ake, he taumaha ake te pepa, ā, he iti ake ngā waeine hei whakauru ki roto i te pouaka kotahi. Hei tauira, mā te whakamahi i te kirihou, 10 karamu noa iho pea o te kirihou e hiahiatia ana hei pupuri i tētahi hanawiti, engari 30 karamu pea o te pepa e hiahiatia ana. Heoi, he mahanga tēnei nā te mea ki te toru ngā wā o te nui o te pepa e whakamahia ana e koe i te kirihou, he iti ake tonu ngā tukunga hau. Heoi anō, he tino iti te Tauwehe Tukunga mō te pepa.

Te Whaihua o te Tango me te Tuku Kai

I roto i ngā takai kai, ehara i te mea ko te oranga tonutanga anake te mea nui. He rite te hiranga o te whaihua ki te oranga tonutanga, nā te mea ki te noho hou tonu te kai i te haerenga uaua mai i te kīhini ki te tatau, ka kiia he mea e manakohia ana. I tēnei wāhanga o te tuhinga, ka tūhuratia e mātou me pēhea te pupuri pai o ia rauemi i te wera, te ārai i ngā turuturu, me te manawanui ki te whakahaere kia whiwhi ai te kaihoko i tētahi kai kounga.

Te Pumautanga Mahi mō ngā Kai

Mō te roa o te ora, he pai ake te kirihou i te pepa. Engari nā te whanaketanga o te hangarau, kei te eke te pepa ki te taumata teitei, me te hanganga matatau hei whakataurite i te mahi a te kirihou:

• Ātete ki te turuturu: Ahakoa e mōhiotia ana he pai ake te ātete o ngā kirihou ki te turuturu nā te mea he ārai kore uru e ārai ana i te wai me te hinu kia uru. I roto i ngā whanaketanga, kei te eke ngā takai pepa ki ngā arai ārai-hinu e whakamahi ana i tētahi paparanga angiangi o te kirihou (Polyethylene/PE) he kirihou koiora rānei (PLA), e ārai ana i te taenga atu ki te muka o te pepa. Mā tēnei ka taea e ngā peihana pepa te pupuri i ngā wai wera (hūpa, ranu) tae atu ki te 2000ml me te kore e makuku.
• Te Pūmautanga o te Wera: He pumau ake te pepa ki te pāmahana, ā, he pai mō te tu atu ki ngā pāmahana iti, teitei rānei, he kōwhiringa pai hoki mō ngā ngaruiti me ngā pouaka whakamātao me te kore e ngaro te āhua.
• Pūmautanga Hanganga: Mā ngā taha moroiti-rara ka pumau te haere i te wā e kawe ana, ā, ka ārai i te hinga ina whakatakotoria ki roto i ngā putea tuku.

Te whānuitanga o te hoahoa me te whakamahinga

Ki te whakaritea ki ngā kirihou, he pai rawa atu ngā kōwhiringa whakaritenga a te pepa, he pai hoki mō te waitohu me te mahi hei whakarei ake i te wheako kaiwhakamahi. Ko ngā āhuatanga matua ko:

• Ngā Āhuatanga Ritenga: He māmā te whakauru i ngā matapihi, ngā kakau, me ngā wāhanga mō ngā wāhanga kai motuhake.
• Te Manawa: Mā te pepa ka puta te mamaoa, ka noho pakari tonu ngā kai parai, engari mā te kirihou ka makuku.
• Taputapu Haereere: Ka tautokohia ngā kai kawe māmā me ngā taputapu kai ātete-wera.
