ʻO ka waikawa Polylactic (PLA) kahi polymer i polymerized me ka waikawa lactic ma ke ʻano he mea maka nui, kahi i loaʻa piha a hiki ke hana hou ʻia. ʻAʻohe haumia o ke kaʻina hana o ka waikawa polylactic, a hiki ke biodegraded ka huahana e hoʻokō ai i ke kaʻapuni ʻana i ke kūlohelohe, no laila he mea polymer ʻōmaʻomaʻo kūpono ia. ʻO ka waikawa Polylactic ((PLA)) kahi ʻano hou o ka mea biodegradable nonā huahana palaki, Paʻi 3DʻO ka starch i unuhi ʻia mai nā kumuwaiwai mea kanu hou (e like me ka kulina) ua hana ʻia i ka waikawa lactic ma o ka fermentation a laila hoʻololi ʻia i ka waikawa polylactic ma o ka polymer synthesis.

Loaʻa i ka Poly (lactic acid) ka biodegradability maikaʻi loa a hiki ke hoʻohaumia loa ʻia e 100% o nā microorganisms i loko o ka lepo i loko o hoʻokahi makahiki ma hope o ka haʻalele ʻia ʻana, e hopena ana i ke kalapona dioxide a me ka wai a ʻaʻohe haumia i ke kaiapuni. Hoʻokō maoli "mai ke ʻano, no ke ʻano". ʻO nā hoʻokuʻu kalapona dioxide o ka honua e like me nā hōʻike nūhou, e piʻi ka mahana honua i 60 ℃ i ka makahiki 2030. Ke puhi ʻia nei nā plastics maʻamau, e hoʻokuʻu ʻia ai ka nui o nā kinoea ʻōmaʻomaʻo i ka lewa, ʻoiai ua kanu ʻia ka waikawa polylactic i loko o ka lepo no ka hoʻohaumia ʻana. ʻO ka hopena o ke kalapona dioxide e hele pololei i loko o nā mea olaola o ka lepo a i ʻole e omo ʻia e nā mea kanu, ʻaʻole e hoʻokuʻu ʻia i ka lewa, ʻaʻole ia e hoʻoulu i ka hopena hale ʻōmaʻomaʻo.

He kūpono ka Poly (lactic acid) no nā ʻano hana like ʻole e like me ke kālai ʻana i ka puhi a mehoʻoheheʻe ʻana i ka pahuHe maʻalahi ke hana a hoʻohana nui ʻia. Hiki ke hoʻohana ʻia e hana i nā ʻano ipu meaʻai āpau, nā meaʻai i hoʻopili ʻia, nā pahu ʻaina awakea wikiwiki, nā lole i ulana ʻole ʻia, nā lole ʻoihana a me nā lole kīwila mai ka ʻoihana a i ka hoʻohana kīwila. A laila hana ʻia i nā lole mahiʻai, nā lole mālama ola, nā ʻōpala, nā huahana hoʻomaʻemaʻe, nā lole anti-ultraviolet waho, nā lole halelewa, nā moena papahele a pēlā aku, he mea hoʻohiki nui ka manaʻolana mākeke. Hiki ke ʻike ʻia he maikaʻi kona mau waiwai mechanical a me ke kino.

Ua like nā ʻano kino kumu o ka polylactic acid (PLA) a me nā plastics synthetic petrochemical, ʻo ia hoʻi, hiki ke hoʻohana nui ʻia e hana i nā ʻano huahana noi like ʻole. Loaʻa i ka polylactic acid ka ʻōlinolino maikaʻi a me ka transparency, kahi like me ke kiʻiʻoniʻoni i hana ʻia mai ka polystyrene a ʻaʻole hiki ke hāʻawi ʻia e nā huahana biodegradable ʻē aʻe.
