I ko mākou ola i kēlā me kēia lā, ʻike ʻia nā ʻōmole plastik ma nā wahi āpau.Manaʻo wau inā ua ʻike ʻoe aia kahi hōʻailona helu e like me ka hōʻailona triangle ma lalo o ka hapa nui o nā ʻōmole plastik (nā kīʻaha).
ʻo kahi laʻana:
ʻO nā ʻōmole wai mineral, i kaha ʻia i ka 1 ma lalo;
ʻO nā kīʻaha wela wela no ka hana ʻana i ke kī, i kaha ʻia i ka 5 ma lalo;
ʻO nā kīʻaha o nā noodles koke a me nā pahu meaʻai wikiwiki, hōʻike ka lalo i 6;
…
E like me ka ʻike a nā mea a pau, ʻo nā lepili ma lalo o kēia mau ʻōmole plastik he mau manaʻo hohonu, aia ka "code toxicity" o nā hue plastik a e hōʻike ana i ke ʻano o ka hoʻohana ʻana i nā huahana plastik pili.
"ʻO nā helu a me nā code ma lalo o ka ʻōmole" he ʻāpana o ka ʻike huahana plastik i kuhikuhi ʻia i nā kūlana aupuni:
Hōʻike ka hōʻailona triangle recycling ma lalo o kahi ʻōmole plastik i ka hana hou ʻana, a ʻo nā helu 1-7 e hōʻike ana i ke ʻano o ka resin i hoʻohana ʻia i loko o ka plastic, e maʻalahi a maʻalahi ke ʻike i nā mea plastik maʻamau.
“1″ PET – polyethylene terephthalate
He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
ʻAʻohe wela kēia mea a hiki i 70 ° C a kūpono wale no ka mālama ʻana i nā mea inu mehana a i ʻole ka hau.Hiki ke hoʻololi ʻia ke hoʻopiha ʻia me nā wai wela a wela paha, a hiki ke hoʻoheheʻe ʻia nā mea ʻino i ke kino kanaka;ʻO ka maʻamau, hana ʻia nā ʻōmole wai mineral a me nā ʻōmole inu carbonated me kēia mea.
No laila, ʻōlelo pinepine ʻia e hoʻolei i nā ʻōmole inu ma hope o ka hoʻohana ʻana, mai hoʻohana hou iā lākou, a i ʻole e hoʻohana iā lākou i mau pahu e mālama ai i nā mea ʻē aʻe.
“2″ HDPE – polyethylene mānoanoa kiʻekiʻe
He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
Hiki i kēia mea ke pale i nā wela kiʻekiʻe o 110 ° C a hoʻohana pinepine ʻia e hana i nā ʻōmole lāʻau keʻokeʻo, nā lako hoʻomaʻemaʻe, a me nā ipu plastik no nā huahana ʻauʻau.ʻO ka hapa nui o nā ʻeke plastik i hoʻohana ʻia i kēia manawa ma nā hale kūʻai kūʻai no ka mālama ʻana i ka meaʻai i hana ʻia me kēia mea.
ʻAʻole maʻalahi kēia ʻano ipu e hoʻomaʻemaʻe.Inā ʻaʻole maʻemaʻe ka hoʻomaʻemaʻe ʻana, e mau ana nā mea mua a ʻaʻole pono e hana hou ʻia.

He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
Hiki i kēia mea ke pale i nā mahana kiʻekiʻe o 81 ° C, he maikaʻi loa ka plasticity, a he maʻalahi.He mea maʻalahi ka hanaʻana i nā meaʻino i nā wela kiʻekiʻe a hoʻokuʻuʻia i ka wā o ka hanaʻana.Ke komo nā mea ʻawaʻawa i loko o ke kino o ke kanaka me ka meaʻai, hiki iā lākou ke hoʻoulu i ka maʻi kanesa o ka umauma, nā kīnā hānau i nā keiki hou a me nā maʻi ʻē aʻe..
I kēia manawa, hoʻohana maʻamau ʻia kēia mea i nā lole ua, nā mea kūkulu hale, nā kiʻiʻoniʻoni plastik, nā pahu plastik, a me nā mea ʻē aʻe, a ʻaʻole i hoʻohana pinepine ʻia no ka hoʻopili ʻana i ka meaʻai.Inā hoʻohana ʻia, e mālama pono ʻaʻole e wela.
“4″ LDPE – polyethylene haʻahaʻa haʻahaʻa
He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
ʻAʻole ikaika ka wela o kēia ʻano mea a hoʻohana nui ʻia i ka hana ʻana i ke kiʻi ʻoniʻoni a me ka kiʻiʻoniʻoni plastik.
ʻO ka ʻōlelo maʻamau, e hoʻoheheʻe ʻia ke kiʻi ʻoniʻoni ʻoniʻoni PE kūpono i ka wā i ʻoi aku ka mahana ma mua o 110 ° C, e waiho ana i kekahi mau mea hoʻomākaukau plastik ʻaʻole hiki ke decomposed e ke kino kanaka.Eia kekahi, ke wili ʻia ka meaʻai i ke kiʻiʻoniʻoni a hoʻomehana ʻia, e heheʻe maʻalahi ka ʻaila i loko o ka meaʻai i loko o ke kiʻi paʻa.hoʻoheheʻe ʻia nā mea ʻino.
No laila, pono e wehe ʻia ka meaʻai i ʻōwili ʻia i loko o ka ʻili plastik ma mua o ka waiho ʻana i loko o ka umu microwave.
“5″ PP – polypropylene
He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
ʻO kēia mea, hoʻohana mau ʻia e hana i nā pahu ʻaina awakea, hiki ke kū i nā wela kiʻekiʻe o 130 ° C a ʻaʻohe ʻike maopopo.ʻO ia wale nō ka pahu plastik hiki ke waiho ʻia i loko o ka umu microwave a hiki ke hoʻohana hou ʻia ma hope o ka hoʻomaʻemaʻe ʻana.
Eia naʻe, pono e hoʻomaopopo ʻia he kaha “5″ ma lalo o kekahi pahu ʻaina awakea, akā he kaha “6″ ma ka poʻi.I kēia hihia, ʻōlelo ʻia e wehe ʻia ke poʻi i ka wā e waiho ʻia ai ka pahu ʻaina i ka umu microwave, ʻaʻole pū me ke kino pahu.E kau i loko o ka microwave.

He mea ʻawaʻawa ke kīʻaha plastik āu e inu ai?E nānā wale i nā helu ma lalo a ʻike!
He mea kēia i hoʻohana nui ʻia, ʻoi aku ka nui o ka hana ʻana i nā ʻōmole pēpē, nā kīʻaha ākea, a me nā mea ʻē aʻe.no laila, e makaʻala a e makaʻala nui i ka hoʻohana ʻana i kēia ipu plastik.
No laila, ma hope o ka hoʻomaopopo ʻana i ke ʻano o kēia mau lepili plastik, pehea e haki ai i ka "code toxicity" o nā plastic?
4 mau ala ʻike ʻona
(1) Ke ho'āʻo ʻike
ʻO nā ʻeke plastik ʻona ʻole he waiu keʻokeʻo, translucent, a ʻaʻole waihoʻoluʻu a ʻālohilohi, maʻalahi, maʻalahi i ka hoʻopā ʻana, a ʻike ʻia he wax ma ka ʻili;ʻO nā ʻeke plastik ʻona ʻeleʻele a i ʻole melemele māmā ke waihoʻoluʻu a pili.
(2) ʻIke Jitter
E hopu i kekahi wēlau o ka ʻeke plastik a lulu ikaika.Inā kani ʻo ia, ʻaʻole ia he mea make;ina he leo puolo, he mea make.
(3) Hoʻāʻo wai
E kau i ka ʻeke plastik i loko o ka wai a kaomi i lalo.He liʻiliʻi koʻikoʻi ko ka ʻeke plastik ʻona ʻole a hiki ke lana i luna.He umekaumaha kiko'ī ko ka ʻeke plastik ʻona a e pohō.
(4) ʻIke ahi
ʻO nā ʻeke plastik polyethylene non-toxic, hiki ke puhi ʻia, me nā lapalapa uliuli a me nā poʻo melemele.I ka wā e ʻā ana, kulu lākou e like me nā waimaka kukui, honi i ka paraffin, a hoʻemi iki ka uahi.ʻAʻole hiki ke puhi ʻia nā ʻeke plastik polyvinyl chloride ʻawaʻawa a pio ke hoʻopau koke ʻia lākou mai ke ahi.He melemele me ka ʻōmaʻomaʻo lalo, hiki ke lilo i kaula i ka wā i hoʻoluliluli ʻia, a he ʻala ʻala o ka waika hydrochloric.
