Manaʻo ʻia nā mea hana hou e hoʻohana ʻia i ka ʻeke meaʻai

I ka hoʻomaka ʻana o ka poʻe e hoʻouna i nā ʻeke ʻuala i ka mea hana, ʻo Vaux, no ke kūʻē ʻana ʻaʻole i maʻalahi ka hana hou ʻana i nā ʻeke, ʻike ka hui i kēia a hoʻomaka i kahi wahi hōʻiliʻili.Akā ʻo ka ʻoiaʻiʻo, ʻo kēia hoʻolālā kūikawā e hoʻonā wale i kahi wahi liʻiliʻi o ka mauna ʻōpala.I kēlā me kēia makahiki, kūʻai wale ʻia ʻo Vox Corporation i 4 biliona ʻeke ʻeke ma UK, akā 3 miliona wale nō ʻeke ʻeke i hana hou ʻia i loko o ka papahana i ʻōlelo ʻia ma luna, a ʻaʻole lākou i hana hou ʻia ma o ka papahana hana hou ʻana o ka hale.

I kēia manawa, ʻōlelo ka poʻe noiʻi ua hiki mai paha lākou i kahi ʻano hou aʻe.ʻO ke kiʻiʻoniʻoni metala i hoʻohana ʻia i loko o nā ʻeke ʻeke kīkī ʻuala o kēia manawa, nā pahu kokoleka a me nā ʻeke meaʻai ʻē aʻe he mea maikaʻi loa ia no ka mālama ʻana i ka meaʻai maloʻo a maʻalili, akā no ka mea, ua hana ʻia lākou me nā ʻāpana he nui o ka plastic a me ka metala i hui pū ʻia, paʻakikī lākou e hana hou.hoʻohana.

"ʻO ka ʻeke ʻuala ʻuala kahi pahu polymer ʻenehana kiʻekiʻe."wahi a Dermot O'Hare o ke Kulanui o Oxford.Eia naʻe, paʻakikī loa ka hana hou ʻana.

Ua ʻōlelo ka ʻoihana hoʻolei ʻōpala Pelekane ʻo WRAP, ʻoiai ʻo ka ʻōlelo ʻenehana, hiki ke hana hou ʻia nā kiʻiʻoniʻoni metala ma ka pae ʻoihana, mai ka ʻike waiwai, ʻaʻole hiki ke hana hou i kēia manawa.

ʻO ke koho ʻē aʻe i manaʻo ʻia e O'Hare a me nā lālā o ka hui he kiʻi ʻoniʻoni lahilahi i kapa ʻia he nanosheet.Hoʻokumu ʻia ia me nā waikawa amino a me ka wai a hiki ke uhi ʻia i ke kiʻi ʻoniʻoni (polyethylene terephthalate, a i ʻole PET, ʻo ka hapa nui o nā hue wai plastik i hana ʻia me PET).Ua paʻi ʻia nā hopena pili ma "Nature-Communication" i kekahi mau lā aku nei.

Me he mea lā e mālama pono ana kēia ʻano mea ʻino ʻole no ka ʻeke meaʻai."Mai kahi manaʻo kemika, ʻo ka hoʻohana ʻana i nā mea ʻawaʻawa ʻole e hana i nā nanosheets synthetic he mea holomua."wahi a O'Hare.Akā ua ʻōlelo ʻo ia e hele ana kēia ma ke kaʻina hoʻoponopono lōʻihi, a ʻaʻole pono ka poʻe e manaʻo e ʻike i kēia mea i hoʻohana ʻia i ka ʻeke meaʻai ma ka liʻiliʻi loa i loko o 4 mau makahiki.

ʻO kahi ʻāpana o ka paʻakikī i ka hoʻolālā ʻana i kēia mea ʻo ia ka hoʻokō ʻana i nā koi o ka ʻoihana no kahi pale kinoea maikaʻi e pale aku ai i ka haumia a mālama i ka huahana hou.No ka hana ʻana i nā nanosheets, ua hana ka hui ʻo O'Hare i kahi "ala hoʻomāinoino", ʻo ia hoʻi, ke kūkulu ʻana i kahi labyrinth pae nano e paʻakikī ai i ka oxygen a me nā kinoea ʻē aʻe ke hoʻopuehu i loko.

Ma ke ʻano he pale oxygen, ʻoi aku ka nui o kāna hana ma kahi o 40 mau manawa ma mua o nā kiʻi ʻoniʻoni ʻoniʻoni metala, a ʻoi aku ka maikaʻi o kēia mea i ka ʻoihana "ho'āʻo kulou".He mea maikaʻi loa ka kiʻiʻoniʻoni, ʻo ia hoʻi, hoʻokahi wale nō mea PET hiki ke hoʻohana hou ʻia.
