ʻO ka polylactic acid (PLA) he polymer polymerized me ka lactic acid ma ke ʻano he kumu kumu nui, i hoʻopiha piha ʻia a hiki ke hana hou ʻia.ʻO ke kaʻina hana o ka polylactic acid he pollution-free, a hiki i ka huahana ke biodegraded e hoʻokō i ka holo ʻana i ke ʻano, no laila he mea polymer ʻōmaʻomaʻo kūpono.ʻO ka waika polylactic ((PLA)) he ʻano mea biodegradable hou nonā huahana palaki, Paʻi 3D.ʻO ka starch i unuhi ʻia mai nā kumuwaiwai mea kanu hiki ke hoʻololi ʻia (e like me ke kulina) e hana ʻia i lactic acid ma ka fermentation a laila hoʻololi ʻia i polylactic acid e ka polymer synthesis.

ʻO ka poly (lactic acid) he biodegradability maikaʻi loa a hiki ke hoʻohaʻahaʻa loa ʻia e 100% o nā microorganism i ka lepo i loko o hoʻokahi makahiki ma hope o ka haʻalele ʻana, e hopena i ka carbon dioxide a me ka wai a ʻaʻohe pollution i ke kaiapuni.Loaʻa maoli "mai ke ʻano, no ke ʻano".ʻO ka hoʻokuʻuʻana o carbon dioxide o ka honua e like me nā moʻolelo nūhou, e piʻi ka mahana o ka honua i 60 ℃ i 2030. Hoʻopau mau ʻia nā plastik maʻamau, e hoʻokuʻu ʻia ka nui o nā kinoea ʻōmaʻomaʻo i ka lewa, ʻoiai ke kanu ʻia ka polylactic acid i ka lepo no ka hoʻohaʻahaʻa. .ʻO ke kalapona kalapona i loaʻa e hele pololei i loko o ka lepo organik a i ʻole e hoʻomoʻa ʻia e nā mea kanu, ʻaʻole e hoʻokuʻu ʻia i ka lewa, ʻaʻole e hoʻoulu i ka Greenhouse Effect.

He kūpono ka poly (lactic acid) no nā ʻano hana like ʻole e like me ka puhi ʻana a me ka hoʻoheheʻe ʻanahoʻoheheʻe ʻia.He maʻalahi ke hana a hoʻohana nui ʻia.Hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana i nā ʻano meaʻai āpau, nā meaʻai i hoʻopaʻa ʻia, nā pahu meaʻai wikiwiki, nā lole i ulana ʻole ʻia, nā ʻenehana a me nā lole kīwila mai ka ʻoihana a hiki i ka hoʻohana kīwila.A laila hana ʻia i loko o nā lole mahiʻai, nā lole mālama ola kino, nā lole lole, nā huahana maʻemaʻe, nā lole anti-ultraviolet waho, ka lole lole, ka moena papahele a me nā mea ʻē aʻe, ʻoi aku ka maikaʻi o ka mākeke.Hiki ke ʻike ʻia he maikaʻi kona ʻano mīkini a me ke kino.

ʻO nā waiwai kino kumu o ka polylactic acid (PLA) a me ka petrochemical synthetic plastics ua like like, ʻo ia hoʻi, hiki ke hoʻohana nui ʻia e hana i nā huahana noi.ʻO ka polylactic acid ka maikaʻi o ka glossiness a me ka transparency, e like me ke kiʻi i hana ʻia mai ka polystyrene a ʻaʻole hiki ke hāʻawi ʻia e nā huahana biodegradable ʻē aʻe.
