He aha te mea e whakamāmātia ana i roto i ānei kōpū kōhī papaperi, he rerekē ngā hua i tēnei, i te mahinga o te hāngā o ngā kōpū kōhī, i te wā e rere ana, me ngā hua i muri i te whakamātua. Ko te polyethylene, i mōhiotia hoki hei PE, he rerekē i tēnei i te whakamāmātanga i ngā inu kia māmā tonu ki te 95° C, ā, he rerekē hoki i tēnei i te whakamāmātanga i te whakamātua kia kore ai ngā rere, nō reira ko ngā kaiwhakamahi katoa e whakamāhi ana i tēnei, ahakoa ngā huarahi iti. Ko te pānga? I te whakamātua i te PE i te papaperi, he uaua mō ngā kaiwhakamahi kia whakamātua, nā te mea he iti ngā whare whakamātua o te rohe e whakamāhi ana i ngā huarahi e wehe ai i te rākau mai i te papaperi. Ka tātai anō te PLA i te tātai kōrā, i whakamātua hei mea pai mō te taiao nā te whakamātua i tēnei i ngā whare whakamātua o te ao, ā, he rerekē i tēnei i ngā whare whakamātua o te AO. Engari ko ngā whakamātua ā-taiao nei e noho ana i he iti ake i te haurua o ngā tāone o Tiameri. Ko ngā whakamātua i te wai he rerekē anō, he iti ngā huarahi mātātoko, engari me whakamāhi i ngā whakamātua kia pūpū tonu kia kore ai ngā rere, ā, kāore e taea te whakamāhi i ngā hāngā i te 85° C. Me kōrero anō mō te take i tēnei i tātai ai ngā tāngata: kāore te kōhī e whakamātua i te hāngā māmā e tika ana i te reo. Ko ngā whakamātua i te PE i ngā kōpū kōhī e whakamātua ana i ngā inu i te 20–30% ake i ngā kōpū kōhī tātai, ā, he mātauranga tēnei i tātai ai ngā kiritaki o ngā kōhī i tēnei wā i tātai ai i ō rātou kōhī i te ata.
| Āhua o te Whakamātua | Max Temp | Kore whaitua | Paruwehenga |
|---|---|---|---|
| PE | 95°C | Mōhio nui atu | Ruatia |
| PLA | 90°C | Tino pai | Mō ngā whakamāhi i te ao tāwhiri anake |
| Wai-tirohanga | 85°C | Pai | Kawea |
*Ngā raraunga whai hua i tāpirihia mai i ngā whakamātautau i ngā kōpae (MBPak 2023)*
Ka āwhina ngā tiwhikete pai ki te tiaki i ngā kiritaki i ngā kerēme taiao teka, ahakoa he mea nui anake mēnā ka tautokohia e ngā taunakitanga tūturu me te horopaki tika. Ko te tohu FSC e tohu ana ko te rakau e ahu mai ana i ngā ngahere e whakahaerehia ana, i te mea e whakaatu ana te tiwhikete BPI ka taea e te kapu te wahia i te ahumahi i runga i nga paerewa ASTM D6400. Heoi anō, kāore te whai i ēnei tohu e tohu ana ka tika te whakakore i tētahi mea. He iti iho i te haurua o ngā pokapū kōpeke puta noa i Amerika e tango ana i ngā kapu i whakakikoruatia ki te rauemi PLA, ā, ko te nuinga o ngā ratonga tiki mai i te taone e kore e whai whakaaro ki te kohikohi i a rātou. Me whakamātau e te kaimahi wharekai he aha te mahi ā-rohe, kaua ki te whakawhirinaki ki ngā mea e tā ana i runga i te tākai. He nui tonu te tikanga o ngā tirotiro motuhake nā te mea he maha ngā hua e kīia ana he "taiao" he "pōkai" rānei, e wareware ana i ngā taipitopito nui e pā ana ki te nui o te pūngao e whakamahia ana ki te hanga i ngā rauemi PLA, ngā hau hau mai i te kawe i ngā mea huri noa,
I te wā e tere haere ana ngā mea i roto i ngā mahi kai, he nui ake te tikanga o te whakawātea pai i te pupuri i ngā inu kia wera, kia makariri rānei. Kua kite katoa tātou i te mea ka tupu ina wera rawa ngā kapu, ka kino ake rānei, ka puta he wera. Ka noho wera te hanga pakitara rua i ngā inu kia 40 ōrau te roa ake i ngā kapu noa, ā, ka heke iho te pāmahana o waho ki tētahi mea e haumaru ana mō te kaimahi ki te pa, i raro iho i te tohu 45 nekehanga Celsius e āwangawanga ana te hunga whakahaere. Heoi anō, he nui te whakahaere i te pūngao. Ka rere ngā kapu mā ki runga i ngā kaute, ka uaua ki te hopu tika, ā, ka puta he raruraru nui ina rere te hunga tūru i waenganui i ngā tēpu. Ko ētahi kapu hou he mea whai tapawhā motuhake e whakakore ana i te wai, ā, e whakaatu ana ngā kamupene kai e 30% iti iho ngā amuamu mō te pāmahana inu i muri i te huri ki ēnei. Ko te bonus? Kāore ēnei kapu e pakaru ina waihotia mō ngā haora. He pai ake te tū ki te hau, he pai ake te wera, nā reira ka roa te roa o te mahi, kāore e ngū, e kore hoki e whakaraerae.
Ko ngā kōpae kōhao papaperi e toru ngā whakamātautau pūmahara e tika ana ki ngā ratonga pūkenga:
Ko te whakamārama tonu he whāinga o te whakamāhinga pūmahara: ko ngā tāwhai kōhao me ngā tāwhai papaperi ōrite (he iti noa i te 210gsm) ngā whāinga tīmatanga. Ko ngā whakamātautau ā-wāhi hoki e whakamārama ana i te whakamārama ake o ngā āhua pūtahi i te tūranga o ngā 25% i ngā āhua rerekē—pērā i ngā tēpu ā-wāhi, i ngā kāri e neke ana—i ngā āhua tūtahi tāwhai.
Ko te whiriwhiri i te rahi tika mō ngā kapu kawhe pepa ehara i te mea he mea hāngai noa ki te logistics he whakatau pakihi tino nui tēnei e pā ana ki te pai o te whakahaere o ngā mea i ia rā. Ko te nuinga o ngā wāhi e piri ana ki ngā rahi paerewa pēnei i te 8, 12, me te 16 ounce nā te mea he pai te ōrite ki ngā mea e tonoa ana e te iwi: nga kōti espresso, te kawhe maturuturu noa, me ngā inu waiu pēnei i te latte. Ina whakamahia e ngā wharekai ēnei rahi paerewa, ka pai ake te ahuareka o ngā kiritaki. I kite ētahi mahi i ō rātou whakatauranga makona e piki ana i te 15 ki te 20 ōrau noa iho nā te mea he ōrite te āhua o ngā mea katoa, ā, he iti iho te hua i te whakatipu. I te wā e hoko ai i ngā taonga, kaua e whakawhirinaki anake ki ngā tau tawhito o mua. Engari, tirohia ngā tono tūturu me ngā momo inu e tonohia ana i nā tata nei. Mā tēnei e ārai ai i te rere i ngā wā tino pukumahi, i te mutunga rānei o te noho noa iho o te tini kapu. Mā te hoko i te nuinga ka ora te moni i tētahi wāhi i waenganui i te 10 ki te 30 ōrau, engari mēnā anake ka tiakina tika i roto i ngā taiao e āraia ana, e kore ai e whakaraerae te haumākū, e kore ai e puta ngā raruraru kōpeke. Ko te kimi i ngā kaiwhakarato e tuku ana i a koe ki te tono i ngā huinga iti ake ina hiahiatia, he mea whai tikanga hoki, ina koa i ngā wā tino nui pēnei i ngā hararei, ngā huihuinga raumati rānei ina piki ohorere te tono. Ko te mea whakamutunga, engari ko te mea tino iti rawa, kia mahara ki te huri i te kararehe mā te whakamahi i te huarahi tuatahi ki te tuatahi ki waho kia kore ai e pakaru tetahi mea i te wa e tatari ana i runga i nga papa i mua i te tae atu ki nga ringa o nga kaihoko.
Ko te PLA i hanga mai i te patate kōrākore e whakamātua ana hei mea pai ki te taiao, nā te rere o tēnei i ngā whakamātua pāwhara, engari he rerekē ngā wāhi e wātea ana ki te whakamātua i tēnei.
Ko ēnei whakamānaitanga e whakamārama ana i ngā kaihoko mō te whakamātua i ngā rākau i tātai ai, me te whakamātua i ngā kōpū kawhe papaperi i ngā whakamātua pāwhara, ahakoa ko te whakamātua tika i te wāhi e whānui ana ki ngā whakamātua o te rohe.
Ko ngā kōpū e rua ngā pātītī, me ngā tāwhai kōpū e whakamātua ana, e whakapakari ana i te whakamātua, ā, e aki ana i ngā rere kawhe, e whakamārama ana i te haumātua me te whakamātua i te wā o te whakamāhi.
