He aha nā ʻokoʻa ma waena o nā ʻeke plastik maʻamau, nā ʻeke plastik degradable a me nā ʻeke plastik biodegradable?

●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. 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 loaʻa, a me ka hou biomass plastics.

ʻeke plastik biodegradablehe mau ʻeke piha biocompostable a me ka degradable. 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.
