1. ʻIke holoʻokoʻa o ke kaulahao ʻoihana:
ʻO ka inoa piha o ka polylactic acid ʻo ia ka poly lactic acid a i ʻole ka poly lactic acid. He mea polyester molekala kiʻekiʻe ia i loaʻa ma o ka polymerization me ka lactic acid a i ʻole ka lactic acid dimer lactide ma ke ʻano he monomer. No kahi mea molekala kiʻekiʻe synthetic a loaʻa iā ia nā ʻano o ke kumu olaola a me ka degradability. I kēia manawa, ʻo ka polylactic acid kahi plastic biodegradable me ka ʻoihana ʻoi loa, ka hana nui loa a me ka hoʻohana nui ʻia ma ka honua. ʻO ka ʻaoʻao luna o ka ʻoihana polylactic acid nā ʻano mea maka kumu āpau, e like me ka kulina, ke kō, ka beet kō, a pēlā aku, ʻo ka waena waena ka hoʻomākaukau ʻana o ka polylactic acid, a ʻo ka iho i lalo ka hoʻohana nui ʻana o ka polylactic acid, me nā papa ʻaina palekana kaiapuni, nā ʻōpala palekana kaiapuni, a pēlā aku.
2. ʻOihana uka
I kēia manawa, ʻo ka waikawa lactic ka mea maka o ka ʻoihana waikawa polylactic kūloko, a ua hoʻomākaukau nui ʻia ka waikawa lactic mai ka kulina, ke kō, ka pī kō a me nā huahana mahiʻai ʻē aʻe. No laila, ʻo ka ʻoihana kanu mea kanu i hoʻomalu ʻia e ka kulina ʻo ia ka ʻoihana uka o ke kaulahao ʻoihana waikawa polylactic. Mai ka manaʻo o ka hana kulina a me ka wahi kanu o Kina, e hiki aku ka hana kanu kulina o Kina i 272.55 miliona tons i ka makahiki 2021, me kahi pae nui, a ua paʻa ka wahi kanu ma 40-45 miliona heketa no nā makahiki he nui. Mai ka lako lōʻihi o ka kulina ma Kina, hiki ke manaʻo ʻia e paʻa mau ka lako o ka kulina i ka wā e hiki mai ana.
No nā mea maka ʻē aʻe e hiki ke hoʻohana ʻia no ka hana ʻana i ka waikawa lactic, e like me ke kō a me ka pī kō, ʻo ka huina o ka hana a Kina i ka makahiki 2021 he 15.662 miliona tone, ʻoi aku ka haʻahaʻa ma mua o nā makahiki i hala, akā aia nō ma ka pae maʻamau. A ke ʻimi nei nā ʻoihana a puni ka honua i nā ala hou e hoʻomākaukau ai i ka waikawa lactic, e like me ka hoʻohana ʻana i ke kumu kō i loko o nā olonā lāʻau e like me ka mauʻu a me ka sawdust e hoʻomākaukau ai i ka waikawa lactic a i ʻole ke ʻimi ʻana i ke ʻano o ka hoʻohana ʻana i ka methane e hana i ka waikawa lactic. Ma ke ʻano holoʻokoʻa, e paʻa loa ka lako o ka ʻoihana uka o ka waikawa polylactic i ka wā e hiki mai ana.
3. ʻOihana waena
Ma ke ʻano he mea palaho piha, hiki i ka waikawa polylactic ke lawe mai i ka hopena o nā mea maka i loko o ka ʻōnaehana hoʻoulu hou a me ka hana hou ʻana o nā kumuwaiwai, nona nā pono i loaʻa ʻole i nā mea i hana ʻia ma ka petroleum. No laila, ke piʻi nei ka hoʻohana ʻana o ka waikawa polylactic ma ka mākeke kūloko. ʻO ka hoʻohana ʻana o ka kūloko i ka makahiki 2021 he 48071.9 tons, he piʻi ʻana o 40% i kēlā me kēia makahiki.
Ma muli o ka haʻahaʻa o ka hiki ke hana o ka waikawa polylactic ma Kina, ʻoi aku ka nui o ka lawe ʻana mai o ka waikawa polylactic ma Kina ma mua o ka nui o ka mea i hoʻokuʻu ʻia aku. I nā makahiki i hala iho nei, ua piʻi koke ka nui o ka lawe ʻana mai o ka waikawa polylactic ma muli o ke koi kūloko. I ka makahiki 2021, ua hōʻea ka lawe ʻana mai o ka waikawa polylactic i 25294.9 tons. Ua holomua nui ka lawe ʻana aku o ka waikawa polylactic i ka makahiki 2021, a hiki i ka 6205.5 tons, he piʻi makahiki-ma-makahiki o 117%.
Hōʻike pili: hōʻike e pili ana i ka loiloi ʻana o ke au hoʻomohala a me ka wānana i ka manaʻolana hoʻomohala o ka ʻoihana huahana polylactic acid o Kina mai 2022 a 2028 i hoʻopuka ʻia e Zhiyan consulting
4. ʻOihana iho
I nā noi ma hope, ua hoʻopili ʻia ka waikawa polylactic ma nā ʻano he nui me kona biocompatibility kū hoʻokahi a me ka biodegradability. I kēia manawa, ua hoʻohana nui ʻia i loko o ka ʻōpala pae pili meaʻai, nā mea ʻaina, ka ʻōpala ʻeke kiʻiʻoniʻoni a me nā huahana a me nā ʻano ʻē aʻe. No ka laʻana, hiki ke hoʻohaʻahaʻa loa ʻia ka ʻili plastik mahiʻai i hana ʻia me ka waikawa polylactic a nalowale ma hope o ka ʻohi ʻana i nā mea kanu, ʻaʻole ia e hōʻemi i ka nui o ka wai a me ka momona o ka lepo, akā e pale aku hoʻi i nā kumukūʻai hana a me nā hana hou e pono ai no ka hoʻōla ʻana i ka ʻili plastik, ʻo ia ke ʻano maʻamau o ka hoʻomohala ʻana o ka ʻili plastik ma Kina i ka wā e hiki mai ana. ʻO ka ʻāina i uhi ʻia e ka ʻili plastik ma Kina ma kahi o 18000 heketa, a ʻo ka hoʻohana ʻana o ka ʻili plastik i ka makahiki 2020 he 1357000 tons. Ke hiki ke hoʻolaha ʻia ka ʻili plastik degradable, loaʻa i ka ʻoihana waikawa polylactic kahi ākea no ka hoʻomohala ʻana i ka wā e hiki mai ana.
