No laila, ua hoʻi mai nā crocs, inā ʻaʻole, ʻaʻole loa lākou e pau i ke ʻano. He hoʻomoana anei kēia? ʻoluʻolu? Nostalgia? ʻAʻole mākou i maopopo. Akā, makemake mākou ma Scienceline i kā mākou Crocs, inā paha ʻo ia ka pālua poni ʻālohilohi a Lyric Aquino i ʻaʻahu ai ma ka lālani mua i kahi ʻaha mele ʻo Harry Styles, a i ʻole ka pālua polū a Delaney Dryfuss i ʻaʻahu ai i ka hale ʻaina ʻano ma Martha's Vineyard. Ke hana pū nei kekahi o kā mākou mau punahele me Crocs e like me Bad Bunny, nā kiʻiʻoniʻoni Cars a me 7-Eleven.
Ua noho nā clogs kaulana no 20 mau makahiki, akā i loko o ia manawa, ʻaʻole mākou i noʻonoʻo i ke ʻano o ko lākou hana ʻia ʻana. Ke hiki mai kēia nīnau i loko o ko mākou noʻonoʻo, ʻaʻole hiki iā mākou ke hoʻopau. No laila, e nānā pono kākou i ke kemika o Crocs a noʻonoʻo pehea e hiki ai iā mākou ke hoʻololi i kona ʻano e hōʻemi i ka kapuaʻi kaiapuni o ka hui.
He paʻakikī ke loaʻa kahi pane pololei ma ka pūnaewele. Ma kekahi mau ʻatikala ua kapa ʻia lākou he rubber, ma kekahi - foam a resin paha. Nui ka poʻe e hoʻopaʻapaʻa nei ʻaʻole lākou he plastic.
Ma ka pae kumu loa, hana ʻia nā Crocs mai ka mea Croslite i hoʻopaʻa ʻia. E ʻeli hohonu iki a e ʻike ʻoe he polyethylene vinyl acetate (PEVA) ka hapa nui o Croslite. ʻO kēia mea, i kekahi manawa i kapa wale ʻia ʻo EVA, no kahi papa o nā hui i kapa ʻia he polymers - nā molekala nui i hana ʻia me nā molekala liʻiliʻi, e hana hou ʻia ana i hoʻopaʻa ʻia. Loaʻa kona ʻano kemika mai nā wahie fossil.
"He palakiko maoli nā ʻaliga. ʻAʻohe kānalua no ia mea," wahi a Michael Hickner, he kanaka ʻepekema mea ma ke Kulanui ʻo Pennsylvania State nāna i loea i nā polymers.
Ua wehewehe ʻo ia he ʻano ākea ka palaki, akā pili pinepine ia i kekahi polymer i hana ʻia e ke kanaka. Manaʻo pinepine mākou he mea laumania a palupalu hoʻi i hoʻohana ʻia e hana i nā ipu lawe a me nā ʻōmole wai hoʻolei. Akā he palaki nō hoʻi ka styrofoam. Pēlā nō hoʻi no ka nylon a me ka polyester i loko o kou lole.
Eia nō naʻe, ʻaʻole hewa ke wehewehe ʻana iā Crocs ma ke ʻano he huʻa, resin a i ʻole rubber - ʻo ia hoʻi nā mea a pau i luna. He ākea a pololei ʻole kēia mau māhele, e pili ana kēlā me kēia i nā ʻano like ʻole o ke kumu kemika a me nā waiwai kino o Crocs.
ʻAʻole ʻo Crocs wale nō ka hōʻailona kāmaʻa e hilinaʻi nei iā PEVA no kona mau kapuwaʻi ʻoluʻolu. A hiki i ka hiki ʻana mai o PEVA i ka hopena o nā makahiki 70 a me ka hoʻomaka ʻana o nā makahiki 80, e like me kā Hickner, ua paʻakikī a ʻaʻole hiki ke kala ʻia nā kapuwaʻi kāmaʻa. "ʻAneʻane ʻaʻohe o lākou pale," wahi āna. "He mea paʻakikī loa ia." Akā ua ʻōlelo ʻo ia ua lawa ka palupalu o ka polymer māmā hou e lilo i mea kaulana i ka ʻoihana kāmaʻa. He mau makahiki ma hope mai, ʻo ka hana hou a Crocs ka hana ʻana i nā kāmaʻa āpau mai kēia mea.
"Manaʻo wau ʻo ke kilokilo kūikawā o Crocs ka hana lima," wahi a Hickner. ʻO ka mea pōʻino, ʻaʻole hōʻike nui ʻo Crocs i ke ʻano o ka hana ʻana o Crocs, akā hōʻike nā palapala patent a me nā wikiō o ka hui e hoʻohana lākou i kahi ʻenehana maʻamau i kapa ʻia ʻo ka injection molding, kahi hana e kuleana no nā mea kālā plastik a me nā piliki Lego. E like me ka pū glue wela, omo kahi mīkini hoʻoheheʻe injection i ka plastic paʻakikī, hoʻoheheʻe iā ia, a hoʻopuka iā ia ma o kahi paipu ma kekahi ʻaoʻao. Komo ka plastic i hoʻoheheʻe ʻia i loko o ka mold, kahi e hoʻomaʻalili ai a lawe i kahi ʻano hou.
Hana pinepine ʻia ke kāpili wela mai ka PVA. Akā, ʻaʻole e like me ke kāpili wela, e hoʻopiha ʻia ka polymer Croslite me ke kinoea e hana i ke ʻano huʻa. ʻO ka hopena, he kāmaʻa hanu, palupalu, a pale wai e kākoʻo a hoʻomalu i ka ʻaoʻao o ka wāwae.
E loli iki ana ke kaʻina hana e hana i nā kāmaʻa plastik i ʻoi aku ka launa pū me ke kaiapuni. Ma kā lākou hōʻike hoʻomau hou loa, ua ʻōlelo ʻo Crocs ua hoʻokuʻu kekahi o kā lākou mau clogs maʻamau i 2.56 kg o CO2 i ka lewa. Ua hoʻolaha ka hui i ka makahiki i hala e hoʻolālā ana lākou e hoʻemi i kēlā helu i ka hapalua ma ka makahiki 2030, ma ka hapa ma o ka hoʻohana ʻana i nā plastik i hana ʻia mai nā kumuwaiwai hou ma mua o nā wahie fossil.
Ua hoʻomohala mua ʻia ka mea bio-based hou, i kapa ʻia ʻo Ecolibrium, e Dow Chemical a e hana ʻia mai "nā kumu mea kanu e like me ka ʻaila tall maka (CTO), ʻaʻole nā ​​​​kumu fossil," wahi a kahi ʻelele Dow ma kahi leka uila. ʻO ka ʻaila Tall, kahi huahana ʻaoʻao o ke kaʻina hana pulp lāʻau i hoʻohana ʻia e hana i ka pepa, loaʻa kona inoa mai ka huaʻōlelo Suedena no ka paina. Ke loiloi nei ka hui i nā koho mea kanu ʻē aʻe, wahi a kā lākou ʻelele.
"ʻO kēlā me kēia koho bio-based i manaʻo ʻia e Dow e pono e hoʻihoʻi ʻia ma ke ʻano he huahana ʻōpala a i ʻole he huahana ʻaoʻao o ke kaʻina hana," i kākau ai lākou.
Ua hōʻole ʻo Crocs e wehewehe inā ua hoʻomaka lākou e hoʻohana iā Ecolibrium i ko lākou mau kāmaʻa. Ua nīnau pū mākou iā Crocs i ka pakeneka o kā lākou mau plastics e hele mai ana mai nā kumu hou i ka hopena o ke au he ʻumi, me ka manaʻo mua e hoʻolālā ana lākou i kahi hoʻololi piha. Ua pane mai ka mea haʻiʻōlelo a wehewehe mai: "Ma ke ʻano he ʻāpana o kā mākou pahuhopu o ka hoʻokō ʻana i ka hoʻokuʻu ʻole ʻana ma ka makahiki 2030, ke manaʻo nei mākou e hōʻemi i nā hoʻokuʻu ʻana mai kekahi mau huahana ma 50% ma ka makahiki 2030."
Inā ʻaʻole e hoʻolālā ʻo Crocs i kēia manawa e hoʻololi piha i nā bioplastics, ma muli paha kēia o nā kumukūʻai palena a me ka loaʻa. I kēia manawa, ʻoi aku ke kumukūʻai o nā bioplastics like ʻole a ʻoi aku ka liʻiliʻi o ka hana ʻana ma mua o nā plastics maʻamau. He mea hou lākou a hoʻokūkū me nā kaʻina hana kuʻuna "i hoʻokumu nui ʻia," wahi a Jan-Georg Rosenboom, he ʻenekinia kemika ma MIT. Akā inā e hoʻomau ka ulu ʻana o ka ʻoihana bioplastics, manaʻo ʻo Rosenboom e hāʻule nā ​​​​kumukūʻai a piʻi aʻe ka loaʻa ma muli o ka hoʻonui ʻia o ka nui o ka hana ʻana, nā ʻenehana hou a i ʻole nā ​​​​lula.
Hoʻolālā pū ʻo Crocs e hoʻohana i nā ʻenehana ʻē aʻe e hōʻemi i nā hoʻokuʻu kalapona, e like me ke hoʻololi ʻana i ka ikehu hou, akā e like me kā lākou hōʻike 2021, ʻaʻole e hana ʻia kēia hoʻololi a hiki i ka hapa lua o kēia kenekulia. A hiki i kēlā manawa, ʻo ka hapa nui o ka hōʻemi e hele mai ana mai ka hoʻoponopono ʻana i kekahi mau plastik i hoʻokumu ʻia i ka wahie fossil me nā koho ʻē aʻe i hou.
Eia nō naʻe, aia kekahi pilikia nui ʻaʻole hiki i kēia palaki bio-based ke hoʻoponopono: kahi e hele ai nā kāmaʻa ma hope o ko lākou pau ʻana. Ua ʻike ʻia nā alligators he lōʻihi ke ola. Ma kekahi ʻaoʻao, ʻo ia ke kū'ē loa i nā pilikia wikiwiki e ʻeha nei ka ʻoihana. Akā ma ka ʻaoʻao ʻē aʻe, pau nā kāmaʻa i nā ʻōpala, a ʻo ka biodegradability ʻaʻole ia he biodegradability.
"ʻIke ʻoe, ʻaʻole hiki ke luku ʻia nā Crocs, ʻo ia ka mea e hoʻoulu ai i nā pilikia hoʻomau," wahi a Hickner. Kuhi ʻo ia he nui aku paha nā crocodiles ma ka Pacific Garbage Patch.
Ua wehewehe ʻo Hickner ʻoiai hiki ke hana hou ʻia ka hapa nui o PEVA me nā kemika, ʻaʻole hiki ke hana pū ʻia me nā hana hou ʻana o ka hale. Pono paha ʻo Crocs e hana i kā lākou kahawai hana hou ponoʻī, e hana hou ana i nā kāmaʻa kahiko e hana i nā mea hou.
"Inā makemake ʻo Crocs e hana i kahi ʻokoʻa, e loaʻa iā lākou kahi papahana hana hou," wahi a Kimberly Guthrie, nāna e aʻo i ke kūʻai aku ʻana a me ke kūpaʻa ʻana o ke ʻano ma ke Kulanui ʻo Virginia Commonwealth.
Ua hui pū ʻo Crocs me ka mea kūʻai aku pūnaewele thredUP e ʻimi i kahi home hou no nā clogs o ke kau i hala. Ke hoʻolaha nei ʻo Crocs i kēia hui pū ʻana ma ke ʻano he ʻāpana o kāna kūpaʻa e hōʻemi i ka nui o nā kāmaʻa e pau ana i nā ʻōpala. Ke hoʻouna ʻoe i nā lole a me nā kāmaʻa i hoʻohana ʻia i kahi hale kūʻai pūnaewele consignment, hiki iā ʻoe ke kau inoa no Crocs Shopping Points.
ʻAʻole i pane mai ʻo ThredUP i kahi noi e ʻike i ka nui o nā pālua i hiki i nā hale kūʻai lole kahiko a i kūʻai ʻia aku paha i nā lumi lole hou. Eia nō naʻe, hāʻawi wale aku kekahi poʻe i ko lākou mau kāmaʻa kahiko. Ma ka ʻimi ʻana iā thredUP, loaʻa iā ʻoe nā ʻano kāmaʻa Crocs like ʻole i nā kala a me nā nui like ʻole.
Ua ʻōlelo pū ʻo Crocs ua hoʻopakele lākou ma mua o 250,000 mau kāmaʻa mai ka ʻōpala i nā makahiki ʻelima i hala ma o kā lākou papahana hāʻawi. Eia nō naʻe, ʻo kēia helu ke kumu e hāʻawi ai ka hui i nā kāmaʻa i kūʻai ʻole ʻia ma kahi o ka hoʻolei ʻana iā lākou, a hāʻawi ka papahana i nā kāmaʻa i ka poʻe e pono ai. Eia naʻe, ʻoiai ke kūpaʻa o Crocs i ka hoʻomau ʻana, ke hoʻomau nei ka hui i ka paipai ʻana i kāna mau lālā Crocs Club e hoʻi mai no nā mea hou loa i nā clogs plastik paʻa.
No laila he aha kā kēia e waiho nei iā mākou? Paʻakikī ke ʻike. Ua ʻoluʻolu iki mākou no ka nalo ʻana o kā mākou hui pū ʻana me Bad Bunny i kūʻai ʻia aku a pau, ʻālohilohi i ka pouli, akā ʻaʻole no ka manawa lōʻihi.
He mea kākau moʻolelo ʻepekema ʻo Allison Parshall me ka makemake nui i ka haʻi moʻolelo multimedia. Kākau pū ʻo ia no Quanta Magazine, Scientific American a me Inverse.
ʻO Delaney Dryfuss ke Luna Hoʻoponopono Nui o Scienceline i kēia manawa a he mea noiʻi no Inside Climate News.
Aloha au i kāu mau koloka, akā, ʻoi aku ke kumukūʻai o kekahi. E ʻoluʻolu e hoʻouna mai iaʻu i kāu pālua hou loa, ka nui 5. Ua ʻaʻahu au i kaʻu pālua hope loa no nā makahiki he nui. E mālama i ke kaiapuni a e ola maikaʻi.
Ke lana nei koʻu manaʻo e like me ko lākou maikaʻi i kēia manawa no ka mea ʻo ko lākou palupalu wale nō ka mea hiki iaʻu ke komo i ka hana ma muli o koʻu ʻāʻī a me nā pilikia ʻē aʻe e pili ana i koʻu mau wāwae. Ua hoʻāʻo nui au no ka ʻeha wāwae a pēlā aku. ʻO nā insoles Orthotic… ʻaʻole hana akā ʻo wau ka mea hiki ʻole ke komo i nā kāmaʻa a ʻaʻole paha i loaʻa iaʻu kahi mea kūpono iaʻu a i kēlā me kēia manawa aʻu e hele ai e kaomi lākou i ka pōpō o koʻu wāwae, a loaʻa iaʻu ka uila a i ʻole kekahi mea like. me he mea lā aia kekahi mea i loko ʻaʻole pono e noho ma laila… makemake wale au e palupalu lākou e like me ke koena i hiki iaʻu ke hoʻomau i ka hana.
Ma hope o ka heluhelu ʻana i kēia, ua manaʻo wau e hōʻino ʻo Crocs i kā lākou huahana. ʻO kēia nā kāmaʻa maikaʻi loa ma ka mākeke i kēia manawa ma ke ʻano o ka ʻoluʻolu a me ke kākoʻo. No ke aha e hoʻopunipuni ai i ka holomua a hōʻino i kahi mea maikaʻi. Ke hopohopo nei au no nā crocs i kēia manawa, i koʻu ʻike ʻaʻole hiki iaʻu ke kūʻai hou iā lākou.
Aia wau ma ke kahakai ma Oregon e huki ana i ʻelua mau ʻaligato limu. ʻIke loa, ua lōʻihi ko lākou noho ʻana i loko o ka wai, no ka mea, ua uhi ʻia lākou e nā mea ola kai a ʻaʻole i haki iki. Ma mua, hiki iaʻu ke iho i kahakai a loaʻa ke aniani kai, akā i kēia manawa hiki iaʻu ke loaʻa wale ka palakiko - nā ʻāpana nui a me nā ʻāpana liʻiliʻi. He pilikia nui kēia.
Pono wau e ʻike i ka mea hana nui loa o kēia mau kāmaʻa, hana mākou i nā mea hoʻonaninani kāmaʻa, kūʻai aku mākou ma mua o 1000 mau pālua i kēlā me kēia mahina, ua nele mākou i kēia manawa.
He mea paʻakikī ke ʻike inā he kūpono kekahi o kēia mau manaʻo a he hoʻopunipuni wale paha i nā bots. I koʻu manaʻo, ʻo ke kūpaʻa ma Crocs ua like ia me kahi hui o nā piliona e kau inoa ana i ka Giving Pledge a hāʻawi aku i ka hapalua o ko lākou waiwai. ʻAʻohe o lākou e komo ikaika ana i kēia, akā ua loaʻa iā lākou ka nui o ka hoʻolaha no kā lākou mau ʻōlelo. Ua hōʻike ʻo Crocs Inc. i ka loaʻa kālā makahiki moʻolelo o $3.6 biliona, piʻi 54% mai ka makahiki 2021. Inā makemake maoli lākou i nā hui e lawe i ke kuleana no ka waiwai maoli o ko lākou mau kāmaʻa, aia ke kālā no ka hoʻopukapuka hoʻomau. I ka wā e apo ai ka hanauna ʻōpio i kēia mau kāmaʻa a me ke kūpaʻa, hiki iā Crocs ke lilo i moʻolelo MBA inā e hoʻolohe lākou i nā loli o nā mea kūʻai aku. Akā ʻo ka hana ʻana i kēlā mau lele nui hiki ke paʻakikī loa, ʻoiai ʻo ka hoʻopukapuka ʻana i nā ana kūpaʻa pipiʻi he kūʻē loa ia i nā hoʻihoʻi no nā mea kuleana/mea hoʻopukapuka i ka wā pōkole.
