●Ma ke ola o kēlā me kēia lā, ʻoi aku ka nui o nā ʻeke plastik, a ʻokoʻa nā ʻano o nā ʻeke plastik.ʻO ka maʻamau, kakaʻikahi mākou e nānā i nā mea o nā ʻeke plastik a me ka hopena i ke kaiapuni ma hope o ka hoʻolei ʻia ʻana.Me ka hoʻolaha mālie ʻana o ka "plastic ban", ua hoʻomaka ka nui o nā mea kūʻai aku e hoʻolohe i nā ʻeke plastik degradable.Nui nā mea kūʻai aku e hoʻololi i nā ʻeke plastik degradable, akā naʻe, ʻaʻole ʻike nā mea kūʻai aku i ka ʻokoʻa ma waena o nā ʻeke plastik maʻamau, nā ʻeke plastik degradable a me nā ʻeke biodegradable.E ʻae mai iaʻu e haʻi aku iā ʻoe.
ʻEkolu ʻano ʻeke ʻeke i ka wehewehe ʻana, ka pono a me ka hemahema
Wehewehe:
●ʻO nāʻeke'ilika maʻamau he mau mea'ilika'ē aʻe e like me PE, aʻo ka mea nui he resin.ʻO ka Resin kahi hui polymer ʻaʻole i hui pū ʻia me nā mea hoʻohui like ʻole.ʻO Resin ka helu ma kahi o 40 a 100 ka nui o ke kaumaha o ka plastic.Hoʻoholo nui ʻia nā waiwai kumu o nā plastics e ke ʻano o ka resin, akā hoʻokani pū kekahi mea hoʻohui.Loaʻa i nā ʻeke plastik biodegradable ka maʻamau mālama kaiapuni kūloko GB/T21661-2008, ʻoiai ʻaʻole pono nā ʻeke plastik kuʻuna e hoʻokō i kēia maʻamau.He 200 mau makahiki a ʻoi aʻe paha ka hoʻohaʻahaʻa ʻana o nā ʻeke plastik kahiko ma hope o ka hoʻolei ʻia ʻana.E hoʻoulu i ka "pollution keʻokeʻo" i ke kaiapuni.
●Degradable plastic eke: Literally, he degradable plastic bag, 'o ia hoʻi, hiki ke hoʻohaʻahaʻaʻia, akā naʻe i loko o ka'ilika a me nā mea'ē aʻe e pili ana, akā, ua hoʻohaʻahaʻa waleʻia,ʻaʻole i hoʻohaʻahaʻa loa.Hana ʻia ia me ka polyethylene plastic, i hoʻohui ʻia me ka photodegradant a me ka calcium carbonate a me nā pauka mineral ʻē aʻe, ʻike ʻia hoʻi he ʻeke plastik photodegradable.Hoʻopau ʻia kēia ʻano ʻeke plastik ma lalo o ka hana a ka lā.Eia nō naʻe, ke noho mau nei ka polyethylene ma hope o ka hoʻokaʻawale ʻana i ka fen i ke kaiapuni kūlohelohe.ʻOiai ʻaʻole hiki ke ʻike ʻia ke ola ʻana o ka pollution keʻokeʻo ma ka laina o ka ʻike, ke hoʻomau nei ka pollution keʻokeʻo i ko mākou wahi a puni ma ke ʻano o nā ʻāpana liʻiliʻi, hiki ke ʻōlelo ʻia e hoʻōla i nā hōʻailona akā ʻaʻole ke kumu kumu.No ka maʻalahi, ma hope o ka hoʻolei ʻana i ka ʻeke plastik degradable, e hoʻohaumia ʻia ke kaiapuni i kekahi ʻano, e like me ka ʻeke plastik maʻamau.ʻO kona huakaʻi hope loa ua like nō ia me nā ʻeke plastik kahiko.Ma hope o ka hoʻolei ʻia ʻana, komo lākou a pau i nā ʻāina ʻāina a i ʻole e hoʻopau ʻia, a ʻaʻole hiki ke hoʻohaʻahaʻa ʻia e ka ʻoihana ʻenehana kūikawā.No laila, ʻo ka "degradable" he "degradable" wale nō, ʻaʻole like me ka "full biodegradation".ʻO ke ʻano, ʻaʻole hiki ke hoʻonā ʻia nā ʻeke plastik degradable i ka "pollution keʻokeʻo", ʻaʻole hoʻi he "panacea" e hoʻonā i ka haumia ʻeke plastik.ʻO ka mea nui, e hoʻohua nō ia i ka nui o ka ʻōpala, a me nā ʻeke plastik degradable ʻaʻole i hoʻohaʻahaʻa ʻia.
● Nā ʻeke plastik biodegradable: ʻO nā mea waiwai o nā ʻeke plastik biodegradable i haku ʻia me PLA (polyacid) a me PBAT (polyadipic acid).ʻO ia mau mea pū kekahi me PHAS, PBA, PBS, a me nā mea ʻē aʻe, i ʻike ʻia he mau mea pili i ke kaiapuni.ʻO nā huahana ʻōmaʻomaʻo ʻino.ʻO nā mea ʻeke plastik biodegradable, i ʻike ʻia he plastic biodegradable, e pili ana i ka hana a nā microorganism e noho nei ma ke ʻano ma lalo o nā kūlana kūlohelohe e like me ka lepo a i ʻole ka lepo one, a i ʻole ma lalo o nā kūlana kikoʻī e like me nā kūlana compost a i ʻole nā kūlana hoʻoheheʻe anaerobic a i ʻole nā hopena moʻomeheu aqueous.Ke kumu o ka degradation, a hope loa degrades i carbon dioxide (CO2), methane (CH4), wai (H2O) a me ka mineralized inorganic paʻakai o nā mea i loko, a me ka hou biomass plastics.

ʻeke plastik biodegradable
ʻeke plastik biodegradablehe mau ʻeke biocompostable a hiki ke hoʻopau ʻia.Ma lalo o ke kūlana o ka compost degradation, hiki ke hoʻopau piha ʻia i loko o 180 mau lā.ʻO nā huahana hoʻohaʻahaʻa he carbon dioxide a me ka wai, e komo pololei i ka lepo a hoʻopili ʻia e nā mea kanu, hoʻi i ka lepo, a i ʻole ke komo ʻana i ke kaiapuni ākea.Hiki ke hoʻohaʻahaʻa ʻia me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni, no laila mai ke ʻano maoli a no ke ʻano.Hiki ke ʻōlelo ʻia nā ʻeke plastik biodegradable he pani no nā plastics, hiki ke hōʻemi nui i ka pilikia o ka haumia keʻokeʻo ma muli o ka hiki ʻole o nā ʻeke plastik maʻamau ke hoʻoponopono.Hiki iā ia ke hoʻoponopono i ka pilikia o ka pollution plastic, ma mua o ka hoʻōla ʻana i nā hōʻailona.ʻO ka hoʻohana ʻana i nā ʻeke plastik biodegradable e hōʻemi nui i ka haumia o nā huahana plastik i ke kaiapuni.He mea pili kaiapuni, olakino a maʻemaʻe, a hiki ke hoʻohana me ka hilinaʻi.ʻOi aku ka maikaʻi o nā ʻeke plastik biodegradable ma mua o nā mea ʻē aʻe, hoʻohana lōʻihi ma mua o nā ʻeke pepa, a emi ke kumukūʻai ma mua o nā ʻeke pepa.
Hahai & Hoʻokaʻaʻike mai iā mākou
Hiki iā ʻoe ke ʻike i nā huahana like ʻole i kā mākou hale kūʻai.ʻO nā kikoʻī huahana hou aku e ʻoluʻolu e hahai i kā mākou hale kūʻai, e hōʻano hou mākou i ka ʻike ʻelua i ka pule a hoʻokipa e hoʻokaʻaʻike mai iā mākou, e pane koke mākou iā ʻoe.Mahalo iā ʻoe no kāu heluhelu ʻana~
