Ua lilo ka "noho haʻahaʻa kalapona" i kumuhana nui i kēia au hou. I nā makahiki i hala iho nei, ua komo mālie ka palekana kaiapuni ʻōmaʻomaʻo, ka mālama ʻana i ka ikehu, a me ka hoʻēmi ʻana i nā hoʻokuʻu ʻana i ka hihiʻo o ka lehulehu, a ua lilo hoʻi i ʻano hou i kākoʻo ʻia a kaulana nui ʻia i loko o ke kaiāulu. I ke au ʻōmaʻomaʻo a me ke au haʻahaʻa kalapona, ua manaʻo ʻia ka hoʻohana ʻana i nā huahana biodegradable he hōʻailona koʻikoʻi o ke ola haʻahaʻa kalapona, a ua mahalo nui ʻia a hoʻolaha nui ʻia.

Me ka wikiwiki o ke ola, ua lilo nā pahu ʻaina awakea plastik huʻa hoʻolei ʻia, nā ʻeke plastik, nā chopsticks, nā kīʻaha wai a me nā mea ʻē aʻe i mea maʻamau i ke ola. ʻOkoʻa mai ka pepa, ka lole a me nā mea ʻē aʻe, ua hoʻolei ʻia nā huahana plastik ma ke ʻano a paʻakikī ke hoʻohaumia ʻia. ʻOiai e lawe mai ana i ka maʻalahi i ke ola o kānaka, hiki i ka hoʻohana nui ʻana ke hana i ka "haumia keʻokeʻo". Ma kēia ʻano, ua puka mai nā biomaterials biodegradable. ʻO nā mea biodegradable kahi mea e kū mai ana he mau pono koʻikoʻi ma ke ʻano o ka hana kaiapuni i hoʻohālikelike ʻia me nā huahana plastik hoʻolei kuʻuna. ʻO nā huahana i hana ʻia me ka hoʻohana ʻana i nā biomaterials biodegradable ma ke ʻano he mea maka he wahi mākeke nui a lilo i mea lawe koʻikoʻi o ka manaʻo nohona haʻahaʻa kalapona.

Nui nā ʻano mea biodegradable, mePCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, a pēlā aku. I kēia lā e kālele ana mākou i ka mea biodegradable e kū mai ana ʻo PLA.

PLA, ʻike ʻia hoʻi ʻoʻakika polylacticd, CAS 26023-30-3he mea maka starch i hoʻomoʻa ʻia e hana i ka waikawa lactic, a laila hoʻololi ʻia i ka waikawa polylactic ma o ka synthesis kemika a loaʻa iā ia ka biodegradability maikaʻi. Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaumia loa ʻia e nā microorganisms ma ke ʻano, a laila hana i ka carbon dioxide a me ka wai me ka ʻole o ka haumia ʻana i ke kaiapuni. He maikaʻi loa ke kaiapuni, a ua ʻike ʻia ʻo PLA he mea aloha kaiapuni me nā waiwai olaola maikaʻi loa.

ʻO nā mea maka nui o ka PLA he mau olonā mea kanu hou, kulina a me nā huahana mahiʻai a me nā huahana ʻē aʻe, a ʻo ka PLA kahi lālā koʻikoʻi o nā mea e ulu mai ana i ka biodegradable. He mau waiwai kūikawā ko PLA ma ke ʻano o ka paʻakikī a me ka transparency. Loaʻa iā ia ka biocompatibility ikaika, ka laulā o ka noi, nā waiwai kino a me nā mechanical ikaika, a hoʻokō i nā koi hoʻohana like ʻole. Hiki ke hoʻohana ʻia i nā ʻano hana like ʻole no ka hana nui, me ka helu antibacterial o 99.9%, e lilo ia i mea degradable maikaʻi loa.

ʻAkika Polylactic (PLA)He mea hou e pili ana i ke kaiapuni a me ka ʻōmaʻomaʻo biodegradable i hana ʻia mai ka waikawa lactic ma ke ʻano he mea maka; I nā makahiki i hala iho nei, ua hoʻopili ʻia ka PLA i nā huahana a me nā kahua e like me nā ʻōpala, nā mea ʻaina, nā mea hoʻopili kiʻiʻoniʻoni, nā fibers, nā lole, nā mea paʻi 3D, a pēlā aku. Loaʻa iā PLA ka hiki ke hoʻomohala nui i nā kahua e like me nā lako kōkua lapaʻau, nā ʻāpana kaʻa, ka mahiʻai, ka ululāʻau, a me ka palekana o ke kaiapuni.

ʻO ka PLA i hana ʻia eʻOihana Unilongʻo ia ka mea hope loa i loko o kēlā me kēia "particle" polylactic acid. Ma o ke koho pono ʻana o nā mea maka polylactic acid kiʻekiʻe, hoʻohana ʻia ka plastic PLA polylactic acid a me ka fiber PLA polylactic acid e hana i nā pani plastic petroleum olakino, ʻoluʻolu i ka ʻili, kiʻekiʻe ke ʻano, a ikaika antibacterial. ʻO kāna huahana nui e pili ana i nā lole hou, nā kāmaʻa a me nā pāpale, nā mea ʻaina, nā kīʻaha a me nā ipu hao, nā mea kākau, nā mea pāʻani, nā lole home, nā lole a me nā lole paʻa, nā waiwai hale, nā ʻūlū maloʻo a pulu, a me nā ʻoihana ʻē aʻe e pili kokoke ana i ko mākou ola o kēlā me kēia lā.

ʻO ka puka ʻana mai oPLAhiki ke kōkua i nā kānaka e noho mamao aku mai ka haumia keʻokeʻo, e hōʻemi i ka pōʻino plastik, a paipai i ka ʻike kūpono o ka piko kalapona a me ke kūlike kalapona. ʻO ke kumu o Unilong Industry ʻo ia ka "hoʻomau i ka wikiwiki o nā manawa, alakaʻi i kahi nohona aloha kaiapuni", paipai ikaika i nā huahana biodegradable, e ʻai i nā kānaka i ke olakino a ola i ke ola olakino, e ʻae i ka biodegradation e komo i nā tausani o nā hale, alakaʻi i kahi ʻano hou o ke ola ʻōmaʻomaʻo a me ke ola haʻahaʻa-kalapona, a komo piha i ke ola haʻahaʻa-kalapona.
