Neke atu i te $400 piriona te mate ōhanga o te para kai o te ao i ia tau. Haunga ngā utu pūtea, he take nui tēnei o te huringa āhuarangi. E ai ki te UN Food and Agriculture Organization (FAO), tata ki te 13.2% o te kai ka ngaro i mua i te taenga ki te hokohoko, ā, ko tētahi atu 19% ka maumauria i te taumata kaihoko.

I te Interpack 2026, i whakamāramahia e te kaupapa SAVE FOOD te hiahia nui kia nekehia ngā otinga tākai mai i te "tiakitanga kore mahi" ki te tiakitanga kaha. Hikoi irahikoKei te puta ake te hangarau whakamātao (EB) hei taputapu kaha hei whakaiti i te para i ngā taha e rua: te whakapai ake i te mahi takai me te tukatuka tika i te kai. Ka hangaia e tēnei auahatanga e ahu mai ana i te pūtaiao karihi he parenga paparua ki te pirau—mai i te rauemi takai ki te kai i roto.

I te Interpack 2026 i Düsseldorf, Tiamana, ko te arotahi ko te hononga o te mahi me te pumau i roto i ngā takai. Mai i ngā pūmua koiora a BASF ki ngā rauemi hangarua matū a SABIC, me te kaupapa takai paturopi MATE4MEAT a Fraunhofer ki te huihuinga "Whakaiti i te Para Kai" a te kaupapa SAVE FOOD, kei te tere haere te umanga takai o te ao ki te ōhanga porowhita.

Heoi, kei te aroaro o ngā kamupene tākai he wero nui: me pēhea te whakaiti i te pānga ki te taiao me te pupuri tonu i te mahi tiaki, te roa o te wā e mau ana ngā hua, me te whai huatanga o te whakaputanga.

Hikoi irahikoKo te hangarau whakamātao (EB), he tukanga ahumahi kua whakamātauhia mō ngā tekau tau, kei te puta ake hei whakahohe matua. Mā te whakahohe i te hononga ā-tinana, te whakarerekētanga mata, me te tukatuka whakauru me te kore he tāpiringa matū, ka taea e te whakamātao EB te takai kia:

Hiroki ake, kāore e ngaro te kaha,

Rauemi kotahi me te mahi rite ki te hiato, me te

Ka whai wāhi nui ki te whakaroa i te roa o te oranga o te papa.

I roto i ngā ahumahi pēnei i ngā roto me ngā waho o ngā motuka, ngā whare taputapu kāinga, ngā takai tiaki whaiaro, me ngā taonga tākaro, ko tētahi wero e pā ana ki te "kiri o te peita i muri i te rehu ki runga i ngā papa PP (polypropylene) me ngā papa PE rānei." Ahakoa he rite tonu ngā tukanga maimoatanga-mua, ka paahitia e ētahi puranga te mana whakahaere kounga, ko ētahi ka rahua. He maha ngā wā, ko te pūtake o te take ka kitea ki tētahi taahiraa nui: mēnā kua tika te paninga o te paparanga tuatahi.

Wai PP, kaihoko maimoatanga PP, paraime PP—e tohu ana ēnei kupu mōhio katoa ki te otinga kotahi: te kapia polypropylene chlorine (CPP). Engari he aha i Reiti CPP He tino whai hua ki te whakapai ake i te piri ki ngā kirihou "uaua ki te here" pērā i te PP? Me pēhea te hanga i tētahi hononga pono i waenga i te paninga me te papa?

I roto i te umanga takai whakawhāiti wera, kua noho te kiriata whakawhāiti POF (multilayer co-extruded polyolefin) hei huarahi pai ki te whakakapi i ngā kiriata PVC tuku iho. Nā tōna māramatanga teitei, tōna whakawhāititanga pai, tōna ātete makariri, me ōna āhuatanga hoa taiao, he mea tino pai mō te takai paihere me te tiaki mata i roto i ngā mahi kai, inu, rongoā, me te tiaki whaiaro.

Heoi, i te mea e hiahia ana ngā mākete tākai o te ao kia nui ake te whai huatanga o te whakaputa, kia pai ake te ōritetanga, me te iti ake o ngā reiti hapa, kāore ngā kaihoko e aro noa ki ngā raraunga whakahekenga. Kei te piki haere tō rātou āwangawanga ki te āhua o te mahi a ngā kiriata i runga i ngā raina tākai tere-rahi—mēnā he ōrite te whakahekenga, he maeneene ngā hiri, ā, he taea te whakahaere i ngā reiti pakaru. I roto i tēnei horopaki, hihi irahiko Kua ara ake te whakamātaotanga (EB) hei hangarau matua mā ngā kaihanga kiriata POF hei whakapai ake i te ōritetanga o ngā hua me te whakapakari i te whakataetae mākete.

Ko ngā kiriata polyethylene (PE) te rauemi takai e whakamahia whānuitia ana puta noa i te ao. Heoi, nā te hanganga ngota ngota raina e whakawhāiti ana i ngā āhuatanga matua pērā i te kaha miihini, te ātete wera, me te ātete poka. I te whanaketanga o te umanga takai ki ngā otinga māmā, mahi teitei, me te hangarua, kua kore e ranea ngā whakarerekētanga whakaranu tuku iho hei whakatutuki i ngā whakaritenga motuhake.

Ko te hangarau whakamātao whakatere irahiko kua noho hei kaha akiaki i muri i te whakawhiti i ngā kiriata PE mai i ngā "rauemi whānui" ki ngā "rauemi mahi." Mā te hanga i tētahi whatunga hononga-toru-ahu i waenga i ngā mekameka polymer, ngā hihi irahiko ka whakarei ake i ngā āhuatanga o te kiriata PE—ka whakapai ake i te ātete ki te poka, te ātete ki te wera, te ōrite o te mimiti, me te āheinga hangarua—me te kore e whakarerekē i te hanganga turanga.

Me whakataurite ngā kiriata maha-paparanga i whakaputahia ngātahitia i te hiri wera, ngā āhuatanga ārai, te kaha, me te āhua—he maha ngā wā ka pāngia e tētahi, neke atu rānei ngā āhuatanga. I tētahi atu taha, me ātete ngā kiriata ahumahi taumaha ki te poka, ki te haehae, me te roa o te rangi, ka puta he tauwhitinga ngāwari i waenga i te matotoru me te utu. I te nekehanga o ngā hiahia o te kiritaki ki te "angiangi ake," te "kaha ake," me te "hangarua anō," kāore e tutuki ngā whakarerekētanga rauemi tuku iho i te tohu.

Te whakamārama irahiko Mā te hononga whakawhiti ka tukuna he otinga mō tēnei "tapatoru kore e taea" i te taumata ngota. Kāore tēnei hangarau e whakarerekē i ngā rauemi turanga engari ka whakamahia ngā irahiko kaha-teitei hei "whakapiri" i ngā whatunga toru-ahu i waenga i ngā mekameka polymer. Ka whakanuia e tēnei tukanga ngā pānga mahi tahi o ngā hanganga maha-paparanga, ā, ka tino whakarei ake i ngā rohe mahi o ngā kiriata taumaha.

I te mea kei te piki haere tonu te hiahia mō ngā kai kua rite ki te kai me ngā kai kua oti te whakarite, kua noho te whakahoromata pāmahana teitei hei tikanga nui mō te whakarite i te haumaru o te kai me te whakaroa i te roa o te oranga o te kai. He whānuitia te whakamahinga o te whakawhakakorenga pāmahana (85-95°C) mō ngā kai iti-waikawa pērā i te miraka, te wai hua, me te pia, ko te whakahoromata pāmahana teitei, pēhanga teitei (121-135°C) he mea nui mō te mīti, ngā hua soya, me ngā kai nui-pūmua e hiahia ana kia kore e taea te whakahoromata arumoni. Ka tino whakakorea e ēnei maimoatanga wera ngā moroiti engari ka nui hoki ngā tono mō ngā kiriata takai - me pupuri tonu e rātou te hanganga pai, te pono o te hiri, me te pumau o te āhua i raro i ngā pāmahana teitei.

Heoi, he iti noa iho ngā herenga o ngā kiriata kirihou wera tuku iho mō te ātete wera. Hei tauira, ko te pūwāhi whakangawari Vicat o te polyethylene (PE) kei waenganui i te 90-110°C, ā, ka tīmata te whakangawari i ngā pāmahana neke atu i te 85°C. Ahakoa ka taea e te polypropylene (PP) te tu atu ki te wai kohua, kei te tūpono tonu te āhua rerekē i runga ake i te 121°C. Hangarau hononga hihi irahikokua puta ake hei huringa nui, e whakarei ake ana i te ātete wera i te taumata ngota ngota, ā, e aro atu ana ki ēnei wero me te whai hua.

I roto i ngā raina whakaputa tākai tere-rahi, he mea nui ia hēkona ina tae mai ki te mahi kiriata. Mā te piki me te heke o ngā kiriata whakaiti e ±5% ka arahi pea ki te kore e tika te tūnga o ngā tapanga, te koretake o te tākai, ā, i te mutunga, ki te koretake o te mahi whakaputa. Mēnā ka ngaro te kaha o te hiri ki te wera nā te poke o te hinu, o te puehu rānei, ka puta pea he turuturu, he rahunga o te tākai, me te kore e mahi whakaputa. I roto i ngā ahumahi pēnei i te kai me te hauora, he mea kāore e taea te whiriwhiri i te pono o te tākai, he mea nui ake te whakatutuki i te mahi "pūmau" i te whai i ngā āhuatanga "matatau".

He maha ngā wā ka pāngia ngā rauemi tuku iho e whakamahia ana i roto i ngā kiriata whakaiti me ngā paparanga hiri e ngā herenga nā te nekehanga wera o ō rātou mekameka ngota. Ko ngā rerekētanga o te pāmahana, te wā rokiroki, me te tere tukatuka ka arahi pea ki ngā take pēnei i te tere whakaheke, te papatahi iti, me te kaha hiri wera koretake. Hangarau hononga hihi irahikokua hurihia te kēmu mā te raka i te hanganga moroiti o ngā kiriata i te taumata ngota, kia tutuki ai te mahi pumau.

Mai i te 12 o Ākuhata, 2026, ka whakatinanahia katoatia te Ture Whakatakotoranga me te Para Whakatakotoranga (PPWR) a te Kotahitanga o Ūropi, me hangarua ngā takai katoa e tukuna ana ki te mākete o te EU. I taua rā anō, ka whai mana ngā herenga hou mō te PFAS (ngā matū perfluoroalkyl me te polyfluoroalkyl) i roto i ngā takai kai e pā ana ki te kai, me te PFAS takitahi kaua e neke ake i te 25 ppb me te kukū katoa kaua e neke ake i te 250 ppb. Hei tāpiri, ko te kukū katoa o te mata, te cadmium, te mercury, me te hexavalent chromium ka tino herea ki te 100 mg/kg. I taua wā, ka whai mana te paerewa GB 4806.10-2025 a Haina i te marama o Hepetema 2026, ka tino whakaiti i te rohe hekenga bisphenol A mai i te 0.6 mg/kg ki te 0.05 mg/kg. Ko te Ture Whakatakotoranga Kirihou Kai (EU) 2026/245 kua whakahoutia a te EU, e whai mana ana i te marama o Pēpuere 2026, ka whakamanahia hoki ngā herenga hekenga pakari mō ngā matū hou e ono.

I te whanaketanga o ngā ariā o te "takai ma" me te "ōhanga porowhita" mai i ngā kaupapa ahumahi ki ngā whakaritenga ā-ture, hihi irahikoHe mea tino motuhake te hangarau whakamātao (EB). Mā ōna āhuatanga "kāore he tāpiringa, kāore he toenga, he matomato, he iti-waro", ka whakaratohia e te hangarau EB ki ngā kaihanga takai kai he otinga e tino rite ana ki ngā ia ture ā-ao mō te haumaru me te oranga tonutanga.

I roto i te umanga takai, he rerekē, he motuhake hoki ngā tono a ngā kiritaki mō te mahi kiriata. Ko ētahi e hiahia ana ki ngā āhuatanga ārai tino teitei hei whakaroa i te roa o te wā e mau ana, ko ētahi e hiahia ana ki te ngāwari tino pai hei whakauru i ngā āhua takai koretake, te kaha rānei ki te tu atu i ngā tukanga whakahoromata pāmahana teitei. Ko ngā tikanga tuku iho mō te whakarerekē i ngā kiriata, pērā i te whakaranu, te whakakotahitanga paparanga maha, me te hononga matū, he maha ngā wā ka whakawhāitihia e ngā tātai pumau, ngā matapihi tukanga whaiti, me ngā huringa whakarerekētanga roa, ka uaua ai te whakautu tere me te whai hua ki te hiahia e tipu haere ana mō ngā otinga ritenga.

Hikoi irahikoMā te hangarau hihi-e ka tukuna he huarahi hou, he huarahi tino whai hua hoki hei whakatutuki i te "whakaritenga i runga i te tono" o ngā āhuatanga kiriata. Ka mahi hei "kaiwhakarite mahi tika", ka taea e ngā kaihanga te whakarerekē i te hanganga iti o te kiriata me te kore e whakarerekē i te hanganga taketake. Mā te whakahaere tupato i ngā tawhā pēnei i te kaha, te inenga, me te tikanga matawai, te whakamārama hihi-ehe taumata teitei o te ngāwari, e āhei ai te neke mai i te mahi paerewa ki te mahi whakarite me te tino tika.
