Ua ʻike ʻo Allan Griff, ka ʻenehana loea, ka mea kākau no PlasticsToday, a me ka mea ʻoiaʻiʻo ponoʻī, ua ʻike ʻo ia i kahi ʻatikala ma MIT News i piha i nā hoʻopunipuni ʻepekema. Kaʻana like ʻo ia i kona manaʻo.
Ua hoʻouna mai ʻo MIT News iaʻu i kahi hōʻike e pili ana i ka noiʻi e pili ana i nā zeolites, nā mineral porous i hoʻohana ʻia no ka hana ʻana i ka propane mai nā polyolefins ʻōpala (recycled) me kahi catalyst cobalt. Pīhoihoi au i ka hewa ʻepekema a me ka hoʻopunipuni ʻana i ka ʻatikala, ʻoi aku ka noʻonoʻo ʻana i kona kumu ma MIT.
Ua ʻike ʻia nā zeolite porous. Inā hiki i nā mea noiʻi ke hoʻohana i ko lākou nui pore e hana i nā molekala kalapona 3 (propane), he nūhou ia. Akā, ke nīnau nei i ka nīnau e pili ana i ka nui o ka 1-carbon (methane) a me 2-carbon (ethane) a me kāu hana me lākou.
Hōʻike pū ka ʻatikala he mea haumia ʻole nā polyolefins recyclable, he hewa ia no ka mea ʻaʻole ia he mea ʻawaʻawa i ko lākou ʻano paʻa maʻamau - nā paʻa CC ikaika loa, nā kaulahao lōʻihi, haʻahaʻa haʻahaʻa. Manaʻo wau e pili ana i ka ʻona o ka cobalt ma mua o ka plastics.
He kiʻi kaulana ka toxicity o ka plastic plastic ma muli o ka pono o ke kanaka e kūʻē i ka ʻepekema i hiki iā mākou ke manaʻoʻiʻo i ka mea hiki ʻole ke hoʻi i ka ʻoluʻolu o ka wā kamaliʻi ke hiki ʻole ke wehewehe.
Hoʻohui ka ʻatikala i ka PET a me ka PE a loaʻa ke kaha kiʻi (ma luna) o ka ʻōmole soda, i hana ʻia mai PET, ʻokoʻa loa i nā polyolefins a ua hana hou ʻia. ʻAʻole pili, no ka mea, ʻoluʻolu i ka poʻe e ʻike i ka nui o nā ʻōmole plastik a manaʻo he mea ʻino nā plastik āpau.
Hoʻopunipuni ke kaha kiʻi no ka mea e hōʻike ana i ka hānai ʻana o ka plastic ringed (aromatic) a me ka hana ʻana i ka propylene, ʻaʻole propane. ʻOi aku paha ka waiwai o ka propylene ma mua o ka propane a ʻaʻole pono e hoʻohui i nā hydrogens. Hōʻike pū ke kaha kiʻi i ka hana ʻana o ka methane, ʻaʻole makemake ʻia, ʻoi aku ma ka lewa.
Ua ʻōlelo ka ʻatikala he mea hoʻohiki ka ʻoihana waiwai e hana i ka propane a kūʻai aku, akā ʻaʻole hāʻawi nā mea kākau i ka ʻike kālā a i ʻole ka hana ʻana a i ʻole ka ʻikepili kūʻai. A ʻaʻohe mea e pili ana i ka ikehu i nā kilowatt-hola, hiki ke hoʻoemi i ke kaʻina hana i nā poʻe manaʻo kaiapuni. Pono ʻoe e uhaʻi i ka nui o kēlā mau paʻa CC ikaika e uhaʻi i ke kaulahao polymer, kahi hemahema maʻamau i ka hana hou ʻana i ka holomua/kemika koe wale nō kekahi pyrolysis.
ʻO ka mea hope, a i ʻole ka mea mua, ke kāhea nei ka ʻatikala i ke kiʻi kaulana o nā plastics i loko o ke kanaka (a me ka iʻa), me ka nānā ʻole i ka hiki ʻole o ka ʻeli ʻana a i ʻole ke kahe ʻana. Nui loa nā ʻāpana i ke komo ʻana i ka pā o ka ʻōpū a laila kaʻapuni i kahi pūnaewele o nā capillaries. A pehea ka nui, e like me kaʻu e ʻōlelo pinepine ai. Hiki i nā ʻupena iʻa i hoʻolei ʻia ke pōʻino i nā mea ola, akā, ʻo ka hopu ʻana a me ka ʻai ʻana iā lākou.
Eia nō naʻe, makemake nui ka poʻe e manaʻoʻiʻo aia nā micro-plastic i loko o mākou e kākoʻo i ko lākou pono e pale aku i ka ʻepekema, ka mea e hoʻonele iā lākou i ka hōʻoluʻolu o nā hana mana. Hiki iā lākou ke hoʻopaʻa inoa i ka plastic toxic no ka mea:
● ʻaʻole kūlohelohe (akā, he kūlohelohe nā olai a me nā maʻi maʻi);
●he mea kemika (akā, ua hana ʻia nā mea a pau me nā kemika, me ka wai, ka ea, a me mākou);
● hiki ke hoʻololi (akā, ʻo ke anā a me ko mākou kino);
●synthetic (akā, he nui nā lāʻau lapaʻau a me nā meaʻai);
● ʻoihana (akā, he mea noʻonoʻo nā hui a mālama i nā kumukūʻai i ka wā e hoʻoponopono pono ʻia ai).
ʻO ka mea a mākou e makaʻu ai iā mākou iho - hoʻomāinoino.
ʻAʻole wale ka lehulehu unscientific ka manaʻo i kēia ʻano. Ke hoʻolilo nei kā mākou ʻoihana ponoʻī i nā hoʻāʻo e hoʻōki i ka "plastic pollution" e like me ka poʻe kālai'āina i ʻike pololei i ka hoʻomaopopo ʻana i ka moʻolelo e like me ka hana ʻana i ka mea a ka poʻe koho.
He pilikia ʻokoʻa ka ʻōpala mai ka haumia, a hiki i kā mākou ʻoihana plastics ke hōʻemi a pono e hōʻemi i kāna mau poho. Mai poina kākou i ke kōkua ʻana o nā plastic i ka hōʻemi ʻana i nā ʻōpala ʻē aʻe - ka meaʻai, ka ikehu, ka wai - a pale i ka ulu ʻana o ka pathogen a me ka maʻi, akā ʻaʻohe kumu.
ʻAʻole pōʻino nā plastik akā makemake ka poʻe e hewa? ʻAe, a ʻike paha ʻoe i ke kumu.
