Tekau tau ki muri, i te hokonga mai o ngā pēke kawhe maturuturu e ngā kaihoko, kotahi anake te mea i arohia e rātou: "He reka?"

I tēnei rā, i hurihia e rātou te takai, i pānuihia marietia ngā tuhinga iti, ā, ka pātaihia he pātai hou: "Ka ahatia tēnei putea i muri i taku maka atu?"

Mō ngā kaihanga tī motuhake me ngā waitohu tī, ehara i te mea he whakatau mekameka tuku noa iho te whiriwhiri i te rauemi tātari tika, engari he whakatau hanga waitohu. I Tonchant, ka whiwhi mātou i ngā pātai i ia rā mō ngā rerekētanga i waenga i ā mātou tātari kore-whatu paerewa me ā mātou tātari PLA hou.

He painga ō rāua e rua i te mākete. Engari ko tēhea te mea e pai ake ana mō tō tauira pakihi? Me tātarihia kia taipitopito - kaua e titiro noa ki ngā tawhā taiao, engari ki tōna pānga hoki ki tō raina whakaputa me ngā hua.

Kaiwhakataetae: Mata PLA (muka kānga)
He aha tēnei? E hokohokohia ana te PLA (waikawa polylactic) hei "muka kānga". I ahu mai i ngā rauemi tipu hou pērā i te māngaro kānga, te tō rānei. Ina kite koe i aua putea mata hiraka, mārama hoki e āhua rite ana ki ngā papanga papai, ko te tikanga he PLA tēnā.

painga:

Te āro "hoa ki te taiao": Koinei te tino kaupapa hokohoko a te PLA. Ka pirau te PLA, ā, ka taea te whakawairakau i raro i ngā āhuatanga ahumahi. Mena kei runga i te oranga tonutanga, i ngā hua rauropi, i ngā uara "aorangi tuatahi" rānei te hanga o tō ahua waitohu, kāti he mea tino nui te PLA.

Ātaahua ki te titiro: He mārama ake te mata PLA i ngā papanga pepa/kore-whatu tuku iho. Mā tēnei ka kitea mārama e ngā kaihoko te puehu kawhe i roto i mua i te hanga, e tohu ana i te hou me te kounga o te kawhe.

Reka kūpapa: Kāore he tae, kāore hoki he kakara o te PLA kounga teitei, ā, e kore e whakararuraru i te reka o tō tunu kai putiputi, hua rānei.

Ko te mea pono: He nui ake te utu o te rauemi PLA—he 20-30% te utu nui atu i ngā rauemi paerewa. Hei tāpiri, he tairongo ake ki te pāmahana me te haumākū i te wā e rongoa ana.

Paerewa: Kakahu kore-whatu tuku iho (PP/PET)
He aha tēnei? Koinei te mea nui o te umanga. Ko te nuinga o ngā pēke kawhe me te tī maturuturu paerewa i roto i ngā hūpāmakete he mea hanga ki te polypropylene (PP) me te PET rānei.

painga:

Te whai hua o te utu: Mena kei te arotahi koe ki te mākete papatipu, ki ngā toa hokohoko, ki ngā hōtēra rānei, he nui ngā hoko me ngā hua iti, ko ngā papanga kore-whatu tuku iho te mea nui rawa atu.

Pūmautanga: He tino pakari ēnei rauemi. Ka taea e rātou te tu atu i ngā pānga kaha o ngā mīhini tākai aunoa tere-teitei, me te kore e pakaru, ā, he roa te wā e ora ai i roto i ngā āhuatanga āhuarangi rerekē.

Te whakahaere tango: Ko ngā papanga kore-whatu tuku iho he paku matotoru ake te hanganga, e āwhina ana ki te whakaroa i te tere rere, kia taea ai te tango i te wa e tere ringihia ana.

Ko te mea pono: he hua kirihou ēnei. Ahakoa he haumaru, ā, e tutuki ana i ngā paerewa kai, e kore e pirau i roto i ngā ipu wairākau māra.

Ngā āhuatanga whakaputa: Ka taea e tō mīhini te wehewehe i te rerekētanga?
Anei tētahi mea ngaro e kore e whakaaturia e te nuinga o ngā kaiwhakarato rauemi ki a koe: He rerekē te mahi a te PLA i runga i ngā mīhini rerekē.

Nā te mea he rerekē te ira rewa o te PLA i te PP/PET, me tino tika te whakahaere i te pāmahana, ā, ko te mea pai ko te whakamahi i te hangarau hiri ultrasonic. I ētahi wā ka tere rawa te rewa o te PLA nā ngā rīpene hiri wera tuku iho, kāore rānei i te tino kaha te hiri.

Koinei tonu te wāhi e whai wāhi mai ai a Tonchant hei "otinga kotahi-mutu".

Ki te hoko mai koe i ngā rōra i a mātou, mā mātou koe e āwhina ki te whakarerekē i ō mīhini o nāianei kia pai ai te whakahaere i ngā rauemi.

Mena ka whakamahia e koe tā mātou ratonga tākai, ka tukuna atu e mātou ō hua PLA ki tā mātou raina whakaputa ultrasonic hei tākai kia tino tika, kia ma hoki te hiri i ngā wā katoa.

Ki te hoko mai koe i tētahi mīhini i a mātou, ka whirihorahia e mātou kia rite ki ngā rauemi e whakaaro ana koe ki te whakamahi i ngā wā katoa.

Whakatau whakamutunga: Ko tēhea te mea me whiriwhiri e koe?
Tīpakohia te PLA mēnā ka tutuki ngā tikanga e whai ake nei:

Kei te hoko koe i ngā hua papai (neke atu i te $2 te utu mō ia putea taka).

Ko tō mākete whāinga ko Ūropi, ko Hapani, ko te hunga rānei e aro nui ana ki te taiao.

E hiahia ana koe ki te āhua "mata" hiraka, papai hoki.

Kōwhiria te papanga kore-whatu tuku iho mēnā ka tutuki ngā whakaritenga e whai ake nei:

Ka arotahi koe ki te nui o ngā hoko me te whakataetae ki ngā utu.

Ka tuku taonga koe ki ngā hōtēra, ki ngā tari, ki ngā kamupene rererangi rānei.

Mō ngā mekameka tuku taonga uaua, me tino pakari te mahi.

Kei te whakaroa tonu?
Kāore koe e hiahia ki te whakaaro noa. E rua ngā momo tātari e hangaia ana e Tonchant. Ka taea e mātou te tuku atu i tētahi kete tauira whakatairite kei roto ko ngā tātari PLA me ngā tātari kore-whatu paerewa, kia taea ai e koe te hanga i tētahi tauira whakatairite, te whakamātau i ngā rerekētanga, me te wheako i ō rātou kakano.
