Te Ure Polietilene Matatini (HDPE) e whai ana i te mana ki roto i ngā wāhi mahi ā-hapori nā tana mōhiohio whakahirahira ki te hēenga ki te mīhini. Ko tēnei ka whakaaweawe i a ia hei whakahē katoa mo ngā tūtohu nui, ina he tūtohu nui ki te whiuwhiu me ngā wā o te mahana nui. Hei tauira, ko te HDPE te kaiwhakamahi ano tonu mo te hanga i ngā poaka plastiketa me ngā kete e hiahiatia nei te manawa ki roto i ngā wāhi whakarara. Nā ngā rangahau mai i ngā kaiwhakautu materiale i whakaae ai ki te roa o te HDPE, ina he tino whakaaetanga kua taea e ia te noho i waenganui i ngā tekau tau ki muri, karekau i te whakarereke nui.
Ko te HDPE, kore anō ia i te whakarere me te tūpato hoki i ngā āhuatanga o te mātauranga me te wai, e whiwhi ana i tēnei he pai tū tonu mō ngā whakaeke pūkaha. Ka taea e tēnei rauemi te kawe i ēnei mea e rerekē ana, whakamana ai kia kaua e whakapahurea rānei, he mea nui tēnei ki te whakamahara i te mana i roto i ngā poaka me ngā kōpaki whakaeke. Ko ōna āhuatanga kia kaua e kitea te wai he pai tahi rawa i roto i ngā wāhi werawera, tiakina ai ngā mea i roto i te koroni me te whakarere mai. Hei paunga i ngā raraunga o te whakamahi pūkaha, ka noho haumaru tonu te HDPE, ā, ka noho tonu i tēnei ake uara i te whakapā mai i ngā mātauranga nui mo ēnei wā.
Te weheweheanga o ngā kete tūru whakamahere i roto i te HDPE he take anō hei whakaū i aua i waenganui i te rākau me te pūnako. I mēngi ā-putanga ā-tuhi, ā, i whakatakoto nei ki te whakamanawa i ngā hua e waihanga ana i te 1000 lbs. Ko tenei weheweheanga ka tuku tonu i te nuinga o ngā hangaenga me te nui ake o te whakarite i te mahi logistikihana, ka tiakina te mate o ngā kete i te whakawehi i ngā taonga ngenge. Nā reira, ko ngā kete HDPE he whakaaetanga pai mo te whakahaere me te whakatere i ngā hua nui i roto i ngā taiao hanga.
Nui ake ngā pūtea whakamana i muri i te mea hōhonu, nō te mahi whakaputu ki ngā whenua ture tae atu ki te porohita me te rākau. Ka kitea e ngā pakihi e whai ana i te ahumahi i te korenga o ngā pūtea i muri i ngā āhuatanga matua. Ko te whanaketanga o te ahumahi ka noho iti i te hoko anake i ngā whakaputunga, ko tēnā ka heke iho i ngā utu hanga i roto i ngā mahi. Hei tā ngā tohunga take taoka nei, ka āhei ngā pūtea kia pai ake te whakatika moni mō te kāwanatanga o te kāinga ki te iti iho i ngā utu tuatahi. Ko te whanaketanga o ngā whakaputunga ahumahi ka taea te whakaatu i te wāhanga o te hunga whakahaere i runga i te mea ka tino hirahira te whakahaere i te ahumahi.
Te noho tuatahi atu o ngā kōpū whakamahere paparehea he iti i ngā hiahiatanga pātengaro. Ki te paihere ki te rakau ka kitea te rino, ko te mīhini ka taea te koroni, engari e whai mana ana ngā kōpū paparehea i roto i te wā. Ko tēnei ka puta hei whiwhinga iti i ngā utu whakawhiti i muri i ngā kāwanatanga. He mea whakaatu mai i ēnei wharau e hainā nei ko te kino moni i ngā mahi whakahaere me ngā whakawhitinga ka riro i te ara ki te whakamahi i ngā whakarite whakamahere paparehea. Ko te toitū o te paparehea ka whai oranga i te roa, ā, me whai ake ngā pakihi i ō rātou rauemi ki te whiwhinga huarahi anō nā runga i te whakahaere, whakamana iho nei ngā kōpū paparehea hei whiringa pai ai i te take moni i roto i ngā whakarite whakamahere.
Nā ngā kōpū plastik i whai take matua ki te whenua kai me te whenua inu, nā te āheinga ki te whakapāhei i ngā ture hauora me ngā ture haumaru, ā, e waihanga ana i te tautoko i raro i te mīharo. Ko tā rātou aronga nui he mea nui, nā reira ka whakaiti i te whēako bacteria, ā, ka taea te tiaki i ngā mahi kai ki roto i ngā wāhi noa. Hei tauira, ko te rangahau mai i ngā kaiwhakahaere hauora kai e whakaatu ana he pai nui te plastik whakahokia hei whakamahi i ngā kai. Ka taea te whakamahi i ēnei kōpū ki te whakarite i ngā huringa o te whenua, whakamahia ana he whakaaetanga me te whakatika mō te tiaki kai me te tahae.
Ko tētahi o ngā pūtake matua o ngā kete rerei he waihanga mōhio ki ngā paoro rerei, e whakapakiri ana i te whanonga āhuarangi o te raraunga. E awhina ana tēnei waihanga ki te hanga i tētahi reta whakamahinga me te reta horopaki, e tiakina ana ngā momo raruraru logistikī, ka puta ko te mahi e rite ana. Ki ngā tatau mai i ngā kumupūtaiao logistikī, ka nui ake te whanonga pai i te waihanga o ngā raraunga rerei e pai ana. Ko te whakamahinga i ēnei kete me ngā paoro ka whakatika i ngā mahi, ka heke i te wā e pakaru nei i ngā here kore kitea rānei.
Kei roto i te secta ahuwhenua, e hāngai ana ngā kete rereki mo te haere me te whakamahinga pai o ngā kai, whakaiti atu i ngā mate. Ki te whanui o te hanga o ēnei kete, ka whakaiti heke tonu i ngā pūtake wareware, hei tautohe mai i ētahi whakawhitinga ahuwhenua. Inaianei, kei roto i te marae pūtaiao whakarongo, e whai tikanga ana ngā kete whakamahinga rereki ki ngā huringa ture, whakamana i te haere pai o ngā taonga whakaaro. Ko tēnei mōhiotia ki runga i ngā sector, he whiwhi whenua nui te mahi a ngā whakaritenga rerekiriki i te whakamana i ngā paerewa hauora me ngā paerewa pai.
Kei te whai mana te kete rēhita supermārketī 575-250 me tana hanga whakamahora, e mahi ana i te whakariterite o te pūtahi nui, ā, kei te whiwhi i tētahi whiringa pai mō ngā supermārketī e mahi ana i ngā taonga nui rawa. Kua hangaia te whiu hei whiu i te mana wehi nui, ko ngā whakamātau nui kua tohungia he tino taea te kuhu i te 300 lbs ki runga nei, kāore i te hinga, kāore hoki i te whakapae i ngā whare whakamātau materiale. Kia taea ai ēnei pūkenga te whakauru pai o ngā momo rerekē, whakatipu i te wāhi me te haumanu i roto i tētahi āhuatanga pureti.
Ka taea e ngā poraka whiwhi kai te whakapai i tō rātou āhuatanga pūtake ki runga i te tohu paetawhiti me ngā pūnaha kīwari whai wāhi nui, i raro i te kete 575-250 matua. Ko te whakamahere i ēnei kete me ngā tohu poraka whai mana ka whakapai i te āhuatanga matihaki, ā, ka whakapakari i te hokianga pūtake ki runga i ngā kaiwhakamuhimuhi. He maha ngā wheako pūnaha kīwari e tae ana, ā, ka taea e ngā poraka whiwhi kai te whakarite i ngā kete ki ngā āhuatanga o rātou poraka. Ko te rangahau i te kāinga he tino pai rawa te whakaae mai i tēnei tūtohetanga i ngā raraunga whakamahi, ka whakapakari i te hokianga o ngā kaiwhakamuhimuhi, ā, ka whakapai hoki i te ngenge whakamua ki te hoko, ka whakapai i te wāhi whiwhi kai ki te whakangungu i ngā kaiwhakamuhimuhi me te hokianga pūtake.
Kāo kē te whakamahana taiao o te kete 575-250, nō te mea kua hangaia ia nohe ki ngā rerekē hoki e taea ana te whakahokia, e tika ana ki ngā tikanga hokohoko whakatipuritanga. I te mutunga o tōna wā whakamahi, e taea nei ngā rerekē o te kete kia whakahokia iho, he whakaiti i ngā pūtake ā-taiao, ā, he whakarite i te ahumoemoe whakawhitinga. He tohutohu i a ngā whenua taiao e whakaatu nei he whakaiti nui te whakahoki rerekē i ngā paku oneone, e whakaatu ana i te whakatipuritanga o te kete ki ngā kaupapa māngai taiao, ā, e paihere ana ki ngā hokomaha e tiaki i te whakatipuritanga i roto i ō rātou mahi.
Nō te whakamahinga o ngā kete rereke ā-tūranga i te ao hurihuri, ka whai wāhi nui ngā kete rereke whakarerekē nei ki te whakangungu i ngā tikanga o te takutai hurihuri, nā te mea he rerekētanga me te whakahokiwhenuatanga o rātou. Ka tukua e ngā āhuatanga nei he whiwhinga nui ki te whakaheke i ngā pānga taiao i whakapāhai ai ngā mahi hanga me te whakaputu. Ki te whakauru i ngā kete rereke whakarerekē ki ngā mahi, ka taea e ngā pakihi whakangungu i ō rātou tohu aniwaniwa ā-motu me te whakaae ki ngā whakaitanga whakarawea. He mea kitea mai i ngā tatau huringa taiao he hanga kotahi e whai ake ana i te whakamahi i ēnei tikanga, ā, ka awhina ngā marae pakihi ki te iti i ngā momo whakaputu me te whakanui i te whakarawea.
Ko tētahi o ngā painga matua o te whakamahi i ngā kete rerei he wawe ka taea e rātau te whakahoki anō, nā reira ka puta he uara iti i te watea i ā muri i ngā pūtake kē. Ka taea e ngā kaihoko e whakauru ana i ngā rārangi whakahoki e tiaki i ngā taonga me te whakatupu hia he ritenga hanganga e pai ai ki te whenua. Nā ngā rautaki whakahaere watea i whakaatuhia ka kitea e ngā pakihi e whakamahia ana i ngā whakaaetanga whakahoki, ko ngā rautekau watea iti i utaina, nā reira ka taea e rātau hoki te whai hua i te oranga taiao me te tuku hua moni.
