ʻO ka polylactic acid (PLA) he mea biodegradable hou, i hana ʻia me ka starch maka i manaʻo ʻia e nā kumu mea kanu hou (e like me ke kulina). Loaʻa ka Glucose mai ka starch raw material ma o ka saccharification, a laila hana ʻia ka waika lactic maʻemaʻe kiʻekiʻe e ka fermentation o ka glucose a me kekahi mau bacteria, a laila hoʻohui ʻia ka polylactic acid me kekahi kaumaha molekala e ke ʻano synthesis kemika.
Loaʻa iā ia ka biodegradability maikaʻi. Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganism i ke ʻano, a hoʻopuka hope loa i ka carbon dioxide a me ka wai, ʻaʻole ia e hoʻohaumia i ke kaiapuni, he mea maikaʻi loa ia i ka mālama ʻana i ke kaiapuni. ʻIke ʻia ʻo ia ma ke ʻano he mea pili i ke kaiapuni.
ʻO ke ʻano o ka mālama ʻana i nā plastics maʻamau, ʻo ia ka incineration a me ka puhi ahi, ka hopena i ka nui o nā kinoea ʻōmaʻomaʻo i hoʻokuʻu ʻia i ka lewa, aʻo ka polylactic acid plastics i kanu ʻia i loko o ka lepo no ka hoʻohaʻahaʻa ʻana, a komo pololei ka carbon dioxide i ka lepo a i ʻole. hoʻopili ʻia e nā mea kanu, ʻaʻole ia e hoʻokuʻu ʻia i ka lewa a ʻaʻole e hoʻoulu i ka hopena ʻōmaʻomaʻo.
