ʻEke ʻAʻahu ʻAiʻa Biodegradable

ʻO ka pōʻaiapuni o ka ʻeke compostable:
Hana ʻia: lawe ʻia ka mākū kulina mai ka mea maka, he polymer maoli i loaʻa mai ka starch kulina, ka palaoa a i ʻole ka ʻuala.
A laila, hoʻololi nā microorganisms i kahi mole liʻiliʻi o ka waika lactic e hana ma ke ʻano he kumu no ka hana ʻana i nā kaulahao polymer o ka waikawa polylactic.
Hāʻawi nā kaulahao crosslinking o ka polymeric o ka polylactic acid i wahi i ka pepa plastik biodegradable e hana ana ma ke ʻano he kumu no ka wehewehe ʻana i ka nui o nā huahana plastic nonpolluting.
Lawe ʻia kēia ʻāpana plastik i nā ʻoihana hana a me ka hoʻololi ʻana o nā ʻeke plastik.
A laila hāʻawi ʻia lākou i nā hale kūʻai no ka hoʻohana ʻana a me ka hoʻolaha ʻana i nā ʻeke compostable i ko lākou ola i kēlā me kēia lā.
Hoʻohana ʻia ka ʻeke a laila lilo ia i mea ʻino (manawa i manaʻo ʻia e hoʻohana ai: ʻumikūmālua mau minuke)
ʻO ke kaʻina hana o ka biodegradation e lilo i ka manawa i manaʻo ʻia mai 6 a 9 mau mahina.
ʻO nā bioplastics i unuhi ʻia mai ka mākū kulina, ua lilo ia i kumu waiwai pau ʻole a hiki ke hoʻololi hou ʻia, hāʻawi i nā pōkole ola pōkole a paʻa i ka nui o ka mahiʻai nui, ʻai haʻahaʻa i ka wai, hoʻoikaika i ka ulu ʻana o ka ʻāpana mahiʻai a ʻoi aku ka ikaika o ka hoʻonui ʻana o nā mea kanu ala e haʻalele ai.Ma nā kaʻina hana a pau o ke ola, ua emi nā mea hoʻopalapala a hiki i ka 1000% i ka hoʻohālikelike ʻana me ke kaʻina hana o ka hana ʻeke plastik.
ʻO ka ʻokoʻa o ka ʻeke Compostable ʻo ia ka hiki ke hoʻohana ʻia i mea hoʻomomona no nā mea kanu home, a me ia e ulu ai lākou i ke olakino a hoʻoikaika i ka hoʻohana hou ʻana i nā ʻeke plastik.Me nā ʻeke AMS Compostables, ma waho aʻe o ka hana ʻana i ka hoʻohana hou ʻana, pale ʻia ka hōʻiliʻili ʻana i nā ʻōpala pono ʻole no nā ʻōpala hoʻomaʻemaʻe a me ka hoʻohaʻahaʻa ʻana i ka ʻōpala me ka pahuhopu o ka hoʻomaikaʻi ʻana i nā kūlana olakino o ka lehulehu a me ke kaiapuni.
Hoʻohana ka mea maʻamau i kahi ʻeke plastik maʻamau no ka manawa pōkole e like me 12 mau minuke ma mua o ka hoʻolei ʻana, me ka noʻonoʻo ʻole i kahi e pau ai.
Akā i ka manawa i waiho ʻia ai i kahi pae ʻāina, ʻoi aku ka nui o ka hale kūʻai hale kūʻai maʻamau i mau haneli a mau kaukani mau makahiki e wāwahi - ʻoi aku ma mua o ke ola kanaka.ʻO nā ʻeke ka nui weliweli o ka plastic i loaʻa i loko o nā ʻōpū kohola a i ʻole nā ​​pūnana manu, a ʻaʻole ia he mea kupanaha - ma ke ao holoʻokoʻa, hoʻohana mākou ma waena o 1 a 5 trillion ʻeke plastik i kēlā me kēia makahiki.
Kūʻai ʻia nā ʻeke plastik biodegradable ma ke ʻano he ʻoi aku ka maikaʻi o ka kaiaola, hiki ke wāwahi i nā mea ʻino ʻole i ʻoi aku ka wikiwiki ma mua o nā plastik kahiko.Ua ʻōlelo kekahi ʻoihana i kā lākou ʻeke kūʻai "e hoʻohaʻahaʻa a biodegrade i kahi kaʻina hana hoʻomau, hiki ʻole ke hoʻohuli ʻole ʻia" inā pau ia e like me ka ʻōpala i ke kaiapuni.
I loko o kahi noiʻi i paʻi ʻia i kēia pule ma Environmental Science and Technology, ua hoʻokomo nā mea noiʻi i nā ʻeke eco-friendly i hana ʻia mai nā ʻano mea like ʻole a me nā mea plastik a loaʻa mai nā hale kūʻai UK i ka hoʻāʻo.Ma hope o ʻekolu mau makahiki i kanu ʻia i loko o ka ʻāina māla, i hoʻopaʻa ʻia i loko o ka wai kai, i ʻike ʻia i ka mālamalama a me ka ea a i ʻole i hoʻopaʻa ʻia i loko o kahi keʻena hana, ʻaʻohe o nā ʻeke i haki loa i nā wahi āpau.
Kākoʻo ʻia
ʻO ka ʻoiaʻiʻo, hiki i nā ʻeke biodegradable i waiho ʻia ma lalo o ka wai i loko o kahi marina hiki ke hoʻopaʻa piha i nā mea kūʻai.
"He aha ke kuleana o kekahi o kēia mau polymers hou a hou?"i nīnau aku ai ʻo Richard Thompson, he mea olaola moana mai ke Kulanui o Plymouth a me ka mea kākau kiʻekiʻe o ka noiʻi.ʻO ka polymer kahi kaulahao hou o nā kemika i hana ʻia i ke ʻano o ka plastic, inā biodegradable a i ʻole synthetic.
"He paʻakikī lākou i ka hana hou ʻana a lohi loa i ka hoʻohaʻahaʻa inā lilo lākou i ʻōpala i ke kaiapuni," i ʻōlelo ai ʻo Thompson, me ka manaʻo ʻana i kēia mau plastic biodegradable e hoʻonui i nā pilikia ma mua o ka hoʻoponopono ʻana.
ʻO ka mea a nā mea noiʻi i hana ai
Ua hōʻiliʻili nā mea noiʻi i nā laʻana o ʻelima ʻano ʻeke plastik.
ʻO ke ʻano mua i hana ʻia me ka polyethylene kiʻekiʻe - ka plastic maʻamau i loaʻa i nā ʻeke hale kūʻai.Ua hoʻohana ʻia ia e like me ka hoʻohālikelike ʻana no nā ʻeke ʻē aʻe ʻehā i kapa ʻia ʻo ia he ʻoluʻolu:
He ʻeke plastik biodegradable i hana ʻia ma kahi ʻāpana mai nā pūpū ʻoyster
ʻElua ʻano ʻeke i hana ʻia mai ka plastic oxo-biodegradable, aia nā mea hoʻohui i ʻōlelo ʻia e nā hui e kōkua wikiwiki i ka haki ʻana o ka plastic.
He ʻeke compostable i hana ʻia mai nā mea kanu
Hoʻokomo ʻia kēlā me kēia ʻano ʻeke i ʻehā kaiapuni.Ua kanu ʻia nā ʻeke holoʻokoʻa a me nā ʻeke i ʻoki ʻia i loko o ka lepo māla ma waho, i hoʻopaʻa ʻia i loko o ka wai paʻakai i loko o ka marina, waiho ʻia i ka mālamalama a me ka ea ākea, a i ʻole i hoʻopaʻa ʻia i loko o kahi pahu ʻeleʻele i loko o kahi keʻena hoʻomalu wela.
ʻO ka oxygen, ka mahana a me ka māmā e hoʻololi i ke ʻano o nā polymers plastik, wahi a Julia Kalow, he mea hoʻomaʻamaʻa polymer mai Northwestern University, ʻaʻole i komo i kēia noiʻi.Pēlā pū kekahi me ka wai a me ka launa pū ʻana me ka bacteria a i ʻole nā ​​ʻano ola ʻē aʻe.
ʻO ka mea i loaʻa i ka poʻe ʻepekema
ʻOiai i loko o kahi kaiapuni moana paʻakikī, kahi i uhi koke ai nā limu a me nā holoholona i ka plastic, ʻaʻole i lawa ka lōʻihi o ʻekolu mau makahiki e wāwahi ai i kekahi o nā plastics koe wale nō ka koho compostable kumulāʻau, i nalowale i lalo o ka wai i loko o ʻekolu mahina.ʻO nā ʻeke i loaʻa i nā mea kanu, ua mau nō naʻe, ua nāwaliwali ke kanu ʻia ma lalo o ka lepo māla no 27 mahina.
ʻO ka lāʻau lapaʻau wale nō i wāwahi mau i nā ʻeke a pau, ʻo ia ka wehe ʻana i ka ea ākea no nā mahina ʻeiwa, a ma ia ʻano, ʻo ka ʻeke polyethylene maʻamau i ʻoki ʻia i ʻāpana ma mua o ka hala ʻana o 18 mahina.
