Ke ulu nei ka ʻike kaiapuni, e piʻi mau ana ke koi no nā mea ʻē aʻe i ka papa ʻaina plastic disposable kuʻuna.PLA (polylactic acid) mea hiki ke hoʻoheheʻe ʻia, i hana ʻia mai nā kumuwaiwai hou e like me ka kulina a me ka starch, ua loaʻa hou ka kaulana i nā hale ʻaina a me ka lawe ʻana, e lilo i wahi ʻālohilohi hou i ka mākeke mea kūʻai aku.

Ua kipa aku ka poʻe nūhou i kekahi mau ʻoihana hale ʻaina a ʻike ʻia ua hoʻopau mua nā kaulahao alakaʻi i kahi hoʻololi piha iPLA papaʻaina. Ua hōʻike ʻia ke poʻo o ka hoʻomau ʻana o Nayuki's Tea ua hoʻololi piha ka brand i nā mea pili i ka kaiaola no nā mauʻu, ʻeke ʻoki, a me nā mea ʻē aʻe mai ka makahiki 2021. Hoʻohana ka brand ma luna o 30 miliona mau papa pākaukau PLA i kēlā me kēia makahiki, e hōʻemi ana i ka hoʻohana ʻana i ka plastic non-degradable e 350 tons i ka 2021 wale nō. "Ma hope o ka hoʻololi ʻana i ka papa ʻaina PLA, ua hoʻonui ʻia ka hapa o nā loiloi maikaʻi e pili ana i ka 'packaging friendly environment' i nā kauoha lawe i ka 22%, he 15 pakeneka hoʻonui."

Ma ka ʻaoʻao hana, ua alakaʻi ʻia ka ʻoihana pākaukau PLA e nā kulekele a me nā ikaika mākeke. I kēia makahiki, ua hoʻokō ikaika ʻo Guizhou, Beijing, a me nā kūlanakauhale ʻē aʻe "kaʻina plastic, "e koi pono ana i ka ho'ēmi 30% o ka hoʻohana 'ana i ka papaʻaina non-degradable i loko o ka meaʻai a me ka lawe lawe 'ana i loko o nā kūlanakauhale ma luna o ka pae prefecture ma ka hopena o 2025. I mua o nā kulekele maikaʻi, nā hui e like me Hengxin Lifestyle ua hoʻonui i ka hoʻonuiʻana i ka hana. ma kahi o 600-800 miliona mau ʻāpana papa ʻaina i kēlā me kēia makahiki ua hoʻopau ʻo kāna hale hana Thai i kāna mau hoʻouna mua ma ʻApelilanā mākeke papaʻaina, e hoʻonui ana i ka palena waiwai nui ma mua o 31%.

Eia nō naʻe, hopohopo kekahi mau mea kūʻai e pili ana i ka ʻike mea hoʻohana o ka papa ʻaina PLA. Ua wehewehe ka R&D Luna Hoʻokele o Biomaterials ma Kingfa Technology, "ʻO kā mākou papa pākaukau PLA i hana nui ʻia he wela a hiki i 120 ° C a, e like me ka hoʻāʻo ʻana o ka ʻaoʻao ʻekolu, hiki ke kū i nā infusions o ka aila wela a me ka wai paila. Hoʻohaʻahaʻa ʻia ʻo ia ma luna o 90% i ka lepo maoli i loko o ʻeono mahina, i ka hopena decomposing i carbon dioxide a me ka wai. Wahi a ka poʻe i loko o ka ʻoihana, e pōmaikaʻi ana i ka ʻenehana ʻenehana a me ka hōʻemi ʻana i ke kumukūʻai, manaʻo ʻia ka mākeke PLA kūloko e ʻoi aku ma mua o 1.8 miliona tons ma 2025, e like me ka nui o ka mākeke o kahi kokoke i 50 biliona yuan. ʻO ka ʻāpana papa ʻaina e helu no 40% o kēia, e hoʻolalelale ana i ka hoʻololi ʻana o ka ʻoihana papa ʻaina inā hua ʻōmaʻomaʻo.
