I te tau 2019, i puta he ohorere i roto i te umanga inu i roto i tētahi rangahau nā te Whare Wānanga o McGill. I kitea e ngā kairangahau, i te wā i ruia ai te tī ki te pāmahana hanga pia, ka tukuna he āhua...11.6 piriona kirihou moroitime3.1 piriona nanoplasticski roto i te kapu.

Mō ngā waitohu tī, he whakaohooho tēnei.

Mō ngā tekau tau, ko te pēke tī pīramiti "hiraka" i hangaia ki te nairona, ki te PET rānei, te paerewa ahumahi mō te tī rau kore utu kounga teitei. He ātaahua te āhua, ā, ka taea e ngā rau te whakawhānui. Engari i te tipu haere o te mōhiotanga o ngā kaihoko, kei te huri haere te whakamāramatanga o te "tino utu".

Kāore te utu nui e kī ana ko te "reka" anake; engari ko te tikanga"He haumaru mōku, he haumaru hoki mō te ao."

Mena he kaipupuri waitohu tī koe, he kaihanga tī rānei e whakawhānui ana ki te mahi tī, ko te aro atu ki te take kirihou moroiti te huarahi nui ki te hanga whakawhirinaki. Anei me pēhea te whakawhiti i tō raina whakaputa ki tētahi heke mai kore kirihou.

Te Raru o ngā Kirihou "Huna"

Ehara i te mea ko ngā putea nairona anake te raruraru. Ahakoa ngā putea tī pepa tuku iho, he maha tonu ngā wā kei rotongā muka polypropylenehei āwhina i a rātou ki te hiri wera, ki te whakamahi rāneiepikorohaidrinhei whakakaha i te pepa ina mākū.

Ina pā te wai kohua ki ēnei rauemi, kāore e rewa, engari ka taea te pirau i te taumata iti rawa. Kei te inu ō kaihoko i te Oolong maunga teitei, i te Earl Grey waro rānei hei oranga mō rātou—ko te mea whakamutunga e hiahiatia ana e rātou ko te taha o ngā polymer hangai.

Te Otinga: Mata PLA (Muka Kānga)

Ko te huarahi tino whai hua ki te whakakore i ngā kirihou moroiti me te pupuri tonu i te ataahua o te putea piramiti ko te huri kiPLA (Waikawa Polylactic).

He mea hokohoko pinepine te PLA hei "Muka Kānga", he kirihou koiora i ahu mai i ngā māngaro tipu ka taea te whakahou (ko te nuinga he kānga, he tō rānei).

• Te Āhua Ataahua:He rite tonu tōna āhua ki te nairona—he mārama, he kanapa, he kaha.

• Te Rerekētanga:Ehara i te mea he hinu. I raro i ngā tikanga whakawairakau ahumahi, ka pakaru hei wai, hei CO2, me te koiora.

• Te Haumaru:He ārai-bacteriostatic tūturu tōna, ā, kāore e tuku i ngā kirihou moroiti paitini ina werahia.

Te Auahatanga o te Ahumahi:I Tonchant, kua kite mātou i tētahi300% te pikingai roto i ngā uiuinga mō ngā roera mata PLA i ngā tau e rua kua pahure ake nei. Kei te neke te mākete, ā, kei te tere haere.

Ehara i te Rauemi Anake—Ko te Tikanga

Anei tētahi taipitopito hangarau e warewarehia ana e te nuinga o ngā waitohu:Me pēhea te hiri i te putea?

Ka taea e koe te hoko i te mata whatu pirau pai rawa atu o te ao, engari ki te whakamahi koe i te piripiri matū (piri) hei kati i te putea, kei te whakauru anō koe i ngā poke ki roto i te kapu.

Koia te takeHangarau Hiri Ultrasonickāore e taea te whiriwhiri mō te takai hoa-taiao.

Ka whakamahia e ngā mīhini ultrasonic ngā wiri auau teitei hei hono tonu i ngā rauemi. Kāore he pae wera, kāore he kāpia, kāore he here whakarewa.

• Ko te Hua:He tuitui ma, he iti noa iho, ā, he 100% te piri ā-tinana.

• Ngā Tohungatanga o Tonchant:Ehara i te mea ko te mata PLA anake tā mātou e tuku ana. Ka hangaia e mātou teNgā Mīhini Tākai Pēke Tī Aunoae whakamahi ana i tēnei hangarau ultrasonic. Ka whakarite mātou kia tino tika te whakatikatika o te mīhini ki te pūwāhi rewa motuhake o te mata muka kānga, kia kore ai e pakaru, e ngoikore rānei ngā hiri.

He pai te utu mō te whakawhiti?

Kia pono tātou: He nui ake te utu o ngā rauemi PLA i te nairona, i te PET rānei.Heoi, whakaarohia te utu "Mōrearea Waitohu".

Ki te kī mai tētahi kaiwhakataetae he kirihou ō putea, ki te pātai mai rānei tētahi kaihoko,"Ka taea tēnei te whakawairakau?"ā, me kī atu koe kāo, ka ngaro atu taua kiritaki ake tonu atu.

Mā te huri ki te takai pirau ka taea e koe te tā"He mea hanga ki ngā tipu," "Kore-kirihou," me te "Ka taea te whakapūkara"i runga i ō pouaka. I te mākete tī kounga teitei, ko ēnei kereme he whakamārama i te utu teitei ake e taea ai te whakakapi i te pikinga iti o ngā utu rauemi.

Me pēhea te tīmata

Kāore koe e hiahia ki te whakahou i tō mekameka tuku katoa i te pō kotahi.

1. Whakamātauria te Rauemi:Tonoa mai he kete tauira o tā mātou mata muka kānga PLA. Hangaia e koe. Tirohia te mārama me te koretake o te reka.

2. Tirohia ō mīhini:Mena kei a koe ngā mīhini tākai o nāianei, me whakarerekē pea kia taea ai te whakahaere i te PLA. Ka taea e ā mātou kaihangarau te ārahi i a koe ki ngā tautuhinga pāmahana me te kume.

3. Tīmata ki tētahi Raina:Whakarewahia he "Kohinga-Taiao" motuhake mā te whakamahi i ā mātou putea PLA kau kua oti kē te hanga hei whakamātautau i te urupare a te mākete.

Kua rite koe ki te tango i ngā kirihou moroiti i tō waitohu? [Whakapā atu ki a Tonchant] hei matapaki i tēnei rā mō ngā rōra mata PLA, ngā tūtohu ritenga, me ngā otinga tākai ultrasonic.
