He aha nā koho pākaukau biodegradable i kēia manawa?He aha ka ʻokoʻa?Inventory of popular disposable degradable tableware ma ka mākeke
Ma ke ʻano o ka hoʻolaha ʻana i ka mālama ʻana i ke kaiapuni, ʻoi aku ka nui o nā ʻoihana e hoʻololi mālie i nā pahu ʻaina maʻamau me ka papa ʻaina hiki ke hoʻohaʻahaʻa ʻia e hōʻemi i ka pollution kaiapuni.Nui aʻe nā ʻano pahu ʻaina maikaʻi a hoʻohaʻahaʻa ʻia i ka mākeke.
No laila he aha ka pahu awakea biodegradable?He aha nā ʻāpana nui o ka pahu ʻaina hiki ke hoʻohaumia?He aha ka ʻokoʻa ma waena o nā pahu ʻaina degradable i hana ʻia me nā mea like ʻole?
ʻO ka papa ʻaina biodegradable e pili ana i ka papa ʻaina e hiki ke hana i nā hopena biochemical ma lalo o ka hana a nā microorganisms (bacteria, molds, algae) a me nā enzymes i loko o ke kaiapuni kūlohelohe, e hoʻololi ai i ka poʻo waho i nā loli maikaʻi o loko, i ka hopena i ka hana ʻana i carbon dioxide a me ka wai.
ʻEluaʻano o nā mea i hoʻohanaʻia no ka papaʻaina hiki ke hoʻohaʻahaʻaʻia: hoʻokahi i hanaʻia i nā mea kūlohelohe, e like me nā hua pepa, ka'ōpala, ka starch, a me nā mea'ē aʻe, hiki ke hoʻohaʻahaʻa pihaʻia, iʻikeʻia hoʻi he mau mea pili i ka nohona;Hana ʻia kekahi ʻano mai ka plastic e like me ka mea nui, e hoʻohui ana i nā mea e like me ka starch a me nā photosensitizers, hiki ke hoʻohaʻahaʻa ʻia.
I kēia lā, e nānā kākou i nā mea ʻai mea ʻai hoʻopau ʻia ma ka mākeke.
ʻO nā lako kīʻaha ma ka mākoki kulina
He pahu meaʻai biodegradable maʻamau i ka mākeke o kēia manawa.ʻO ke kumu nui o ka starch ʻo ke kulina, no laila ua kapa ʻia ʻo ia i kekahi manawa ʻo kāna starch based.Eia nō naʻe, ʻo kēia ʻano pahu meaʻai ʻo ia ka hui ʻana o ka starch a me ka petroleum kuʻuna PP plastic, i kapa ʻia ʻo bio based ma waho.
ʻO ka papaʻaina ma ka mākoki kulina ka mea e hāʻule ai nā waiwai kino o ka mea holoʻokoʻa ma o ka biodegradation o ka starch, akā ʻaʻole hiki ke hoʻohaʻahaʻa ʻia ka PP i hoʻokumu ʻia i ka aila ma hope o ka hāʻule ʻana.Hiki i ka helu degradation ke piʻi i ka 40% -80% ma muli o ke ʻano o ka pahu ʻaina awakea, no laila hiki ke noʻonoʻo ʻia he pahu ʻaina degradable, ʻaʻole ia he mea hoʻopau piha.
No laila, hiki ke hoʻololi i nā mea ʻai i hoʻopaʻapaʻa ʻia i ka papa ʻaina ma ka mākeke.
Nā lako pākaukau i hoʻoheheʻe ʻia i ka pulp (mea kanu fiber molded tableware)
Ma ke ʻano o nā mea maka, hoʻohana ʻia nā pahu ʻaina awakea i hoʻoheheʻe ʻia i ka pulp e like me ka mauʻu palaoa a me ke kō ma ke ʻano he kumu, me ka ʻole o ka hoʻohui ʻana i nā mea PP.Hoʻokumu ʻia lākou ma o ka pulp molding wet pressing process, a me nā mea hoʻohui meaʻai e like me ka wai a me ka ʻaila hōʻoia i hoʻohui ʻia i ka pulp e hoʻokō i ka hopena o ka paʻa ʻana i ka meaʻai anu a me ka wela.
ʻO nā pahu meaʻai hiki ke hoʻohaʻahaʻa ʻia i nā mea kanu kekahi o nā ʻano pahu ʻaina awakea i ka mākeke o kēia manawa.ʻO ka lawe ʻana i ka ʻāina ʻo Hainan, ʻo ia ka mea mua i pāpā i nā kīʻaha papaʻa plastik, ma ke ʻano he laʻana, ua pāpā loa ʻo Hainan Province i ka hoʻohana ʻana, ke kaʻa ʻana, ke kūʻai ʻana, a me ka mālama ʻana i nā kīʻaha palaka.ʻO nā mea pākaukau i hoʻoheheʻe ʻia i ka pulp me ke kānalua ʻole e lilo i mea hoʻololi i ka plastik kūpono.
ʻO nā pahu ʻaina awakea ʻo Bagasse Sugarcane pulp no ke ʻano degradable piha, hiki ke hoʻohaʻahaʻa loa ʻia i loko o nā lā 90 ma lalo o nā kūlana ʻoihana a hale paha, e hoʻi ana i ke ʻano.He mau mea biodegradable maoli lākou a loaʻa kekahi mau pono ma ke ala o ka pāpā ʻana i ka plastic.
PLA mea hoʻoheheʻe ʻia
Hōʻike pinepine nā pahu ʻaina awakea PLA i nā huahana e hui pū i nā kiʻi ʻoniʻoni PLA me nā huahana i hoʻoheheʻe ʻia i loko o ke kaʻina hana pulp, ʻo ia hoʻi nā huahana i uhi ʻia e PLA.
Hoʻokumu ʻia ka kiʻi ʻoniʻoni PLA composite a hana ʻia mai ka polylactic acid ma ke ʻano he mea maka, hiki ke hoʻomehana ʻia a hoʻohui ʻia i ka pulp molding a me nā huahana pepa.He kiʻiʻoniʻoni biodegradable loa ia.
ʻO ka polylactic acid (PLA) kahi ʻano mea biodegradable hou i hana ʻia mai ka starch i loaʻa mai nā kumuwaiwai mea kanu hou.Loaʻa ʻia nā mea waiwai starch ma o ka saccharification no ka loaʻa ʻana o ka glucose, a laila fermented me kekahi mau kānana e hana ai i ka waikawa lactic maʻemaʻe kiʻekiʻe.A laila, hoʻohui ʻia kekahi waika polylactic kaumaha mole ma o nā ʻano hana synthesis.
Ma ka hoʻohuiʻana i ke kaʻina hana lamination me nā hua pulp i hoʻoheheʻeʻia, hiki ke ho'ōlaʻia ka hoʻohanaʻana i nā mea waiʻole a me kaʻaila, hiki ke hoʻopaʻa i nā pores o nā huahana pulp.I ka hoʻohana maoli ʻana, hoʻemi ka papa ʻaina i ka hanu o ka huahana, ka hopena o ka hana insulation kiʻekiʻe a me ka manawa insulation lōʻihi.
