Hiki ke palaho ʻia ka PLA?
•Ua noho ka waikawa Polylactic, i ʻike ʻia hoʻi ʻo PLA, no nā makahiki he nui. Eia nō naʻe, ua komo koke nā mea hana nui o PLA i ka mākeke ma hope o ka loaʻa ʻana o ke kālā mai nā ʻoihana nui e makemake nui e pani i nā plastics synthetic. No laila, hiki ke palaho ʻia ka PLA?
•ʻOiai ʻaʻole maʻalahi ka pane, ua hoʻoholo mākou e hāʻawi i kahi wehewehe a paipai i ka heluhelu hou aku i ka poʻe hoihoi. ʻAʻole palaho ka PLA, akā palaho ia. ʻAʻole loaʻa pinepine nā enzymes e hiki ke wāwahi i ka PLA i ke kaiapuni. ʻO Proteinase K kahi enzyme e hoʻoulu ai i ka hōʻino ʻana o ka PLA ma o ka hydrolysis. Ua ʻimi nā mea noiʻi e like me Williams i ka makahiki 1981 a me Tsuji lāua ʻo Miyauchi i ka makahiki 2001 i ka nīnau inā paha palaho ka PLA. Ua kūkākūkā ʻia kā lākou mau hopena ma ka puke Biomaterials Science: An Introduction to Medical Materials a ua hōʻike ʻia ma kahi hālāwai o ka European Biomaterials Society. Wahi a kēia mau kumu, ua kāohi nui ʻia ka PLA e ka hydrolysis, kūʻokoʻa o kekahi mau mea biologic. ʻOiai he nui ka poʻe e manaʻo nei he palaho ka PLA, he mea nui e hoʻomaopopo i kēia.
•ʻO kaʻoiaʻiʻo, he mea kakaikahi loa ka hydrolysis o PLA e ka proteinase K a ʻaʻole ia he mea nui e kūkākūkā hou ʻia i ka ʻepekema biomaterial. Manaʻolana mākou e wehewehe kēia i nā pilikia e pili ana i ka biodegradability PLA a e hoʻomau mākou i kā mākou hana e hāʻawi i nā hopena maikaʻi loa no kāu mau pono plastik biodegradable a me ke kaiapuni.
Ihopena n:
He palakika biodegradable ka PLA i hoʻohana nui ʻia i nā mea o kēlā me kēia lā e like me nā ʻeke a me nā kīʻaha hoʻolei. Eia nō naʻe, hiki iā ia ke palaho wale i nā wahi composting ʻoihana a i ʻole nā wahi anaerobic digestion, e hoʻolilo ana i ka palaho i nā wahi kūlohelohe maʻamau i mea paʻakikī. Ua hōʻoia nā noiʻi e palaho iki ka PLA i ke kaiapuni kai.
