I kēia mau lā, kaulana loa nā ʻeke plastik biodegradable, a ua hoʻolaha ʻia nā pae like ʻole o ka pāpā i ka honua, a ʻo ia kekahi o nā ʻano nui o nā ʻeke plastik biodegradable, ʻo PLA maoli kekahi o nā mea nui.E hahai pono mākou i ka mea hana ʻeke peke ʻoihana ʻoihana TOP PACK e hoʻomaopopo i nā ʻeke plastik biodegradable PLA.
- He aha ka PLA a me ke aha i hana ʻia ai?
ʻO ka PLA kahi polymer (polylactic acid) i haku ʻia me nā ʻāpana liʻiliʻi lactic acid.ʻO ka ʻakika lactic kahi ʻakika organik e hana nui i ko mākou ola i kēlā me kēia lā.ʻO ka yogurt a mākou e inu mau ai a i ʻole kekahi mea me ka glucose, hiki ke hoʻololi ʻia i lactic acid, a ʻo ka lactic acid o nā mea hoʻohana PLA mai ka kulina, i hana ʻia mai ka mea maka o ka starch i unuhi ʻia mai ka kulina.
I kēia manawa, ʻo PLA kekahi o nā mea maʻamau i hoʻohana ʻia i nā ʻeke plastik biodegradable, loaʻa kahi hiʻohiʻona ʻokoʻa: ʻO PLA kekahi o nā mea biodegradable non-toxic, kāna mau mea maka mai ke ʻano.
- He aha ka pili o ka hoʻohaʻahaʻa ʻana o PLA?
ʻO ke kaʻina hana biodegradation a me kona lōʻihi e hilinaʻi nui i ke kaiapuni.No ka laʻana, wela, haʻahaʻa, a me nā microbes ʻO ke kanu ʻana i nā ʻeke plastik hiki ke hoʻohaʻahaʻa loa i ka PLA i loko o ka lepo hiki ke hōʻailona o ka pala i loko o ʻeono mahina.
A ʻoi aku ka lōʻihi o ka hoʻohaʻahaʻa ʻana i nā ʻeke plastik biodegradable PLA ma ka lumi wela a ma lalo o ke kaomi.I loko o kahi lumi maʻamau, ʻo ka PLA biodegradable plastic degradation e lōʻihi ka manawa.ʻAʻole e hoʻolalelale ka lā i ka biodegradation (koe wale nō ka wela), a ʻo ka kukui UV wale nō ka mea e nalowale ai ka waihoʻoluʻu a lilo i haikea, ʻo ia ka hopena like me ka hapa nui o nā plastics.
Nā pōmaikaʻi o ka hoʻohana ʻana i nā ʻeke plastik biodegradable PLA
I ka mōʻaukala o ke kanaka, ʻoluʻolu a maikaʻi hoʻi ka hoʻohana ʻana i nā ʻeke plastik, ʻo ia ka hopena i hiki ʻole ke hoʻokaʻawale ʻia nā kānaka mai nā ʻeke plastik i ko lākou ola i kēlā me kēia lā.ʻO ka ʻoluʻolu o nā ʻeke plastik e alakaʻi i nā poʻe e poina ʻo ka mea i hana mua ʻia o nā ʻeke plastik ʻaʻole ia he mea hoʻolele, hoʻohana pinepine ʻia a hoʻolei ʻia.Akā ʻaʻole ʻike ka poʻe he nui ka polyethylene ka mea nui no ka hana ʻana i nā ʻeke plastik, he paʻakikī loa e hoʻohaʻahaʻa.ʻO ka nui o nā ʻeke plastik i hoʻolei ʻia i kanu ʻia i ka lepo, kahi e alakaʻi ai i kahi ʻāina nui ma muli o ke kanu ʻana i nā ʻeke plastik a me ka noho lōʻihi.He haumia keʻokeʻo kēia.Ke hoʻohana nā kānaka i nā ʻeke plastik no nā ʻeke plastik biodegradable, e hoʻopau ʻia kēia pilikia.ʻO ka PLA kekahi o nā plastic biodegradable maʻamau a he polymer i hana ʻia mai ka lactic acid, kahi huahana non-pollument a biodegradable.Ma hope o ka hoʻohana ʻana, hiki ke hoʻopuehu ʻia a hoʻohaʻahaʻa ʻia ka PLA i carbon dioxide a me ka wai ma nā mahana ma luna o 55 ° C a i ʻole ma ka hana ʻana o nā microorganisms waiwai nui o ka oxygen e hoʻokō ai i ka pōʻaiapili waiwai ma ke ʻano.Hoʻohālikelike ʻia me ka d o nā ʻeke plastik maʻamau, pono nā ʻeke plastik biodegradable i mau mahina wale nō e hoʻopau ai i ka hōʻino o ka manawa.ʻO kēia ka mea e hoʻohaʻahaʻa ai i ka ʻōpala o nā kumuwaiwai ʻāina i ka nui a ʻaʻohe hopena i ke kaiapuni.Eia kekahi, ʻo nā ʻeke plastik maʻamau i ke kaʻina hana e hoʻopau i nā wahie mōʻalihaku, ʻoiai nā ʻeke plastik biodegradable e hōʻemi i ka hapalua o nā wahie fossil ma mua o ia.No ka laʻana, inā ua hoʻololi ʻia nā huahana plastik a pau o ka honua e nā ʻeke plastik biodegradable i hoʻokahi makahiki, e hoʻopakele ʻo ia ma kahi o 1.3 biliona barela o nā wahie mōʻalihaku i hoʻokahi makahiki, ʻo ia hoʻi kahi ʻāpana o ka hoʻohana wahie fossil honua.ʻO ka hemahema o PLA ʻo ia nā kūlana degradation koʻikoʻi.Eia nō naʻe, ma muli o ke kumu kūʻai haʻahaʻa o PLA i nā mea ʻeke plastik biodegradable, ʻo ka hoʻohana ʻana i ka PLA ma mua.
