ʻO ka waikawa Polylactic (PLA) kahi mea biodegradable hou, i hana ʻia me nā mea maka starch i hāpai ʻia e nā kumuwaiwai mea kanu hou (e like me ka kulina). Loaʻa ka glucose mai ka mea maka starch ma o ka saccharification, a laila hana ʻia ka waikawa lactic kiʻekiʻe ma o ka fermentation o ka glucose a me kekahi mau bacteria, a laila synthesized ka waikawa polylactic me kekahi kaumaha molekala ma ke ʻano synthesis kemika.
He maikaʻi kona biodegradability. 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, ʻaʻole ia e hoʻohaumia i ke kaiapuni, he mea maikaʻi loa ia no ka pale ʻana i ke kaiapuni. Ua ʻike ʻia he mea aloha i ke kaiapuni.
ʻO ke ʻano o ka mālama ʻana i nā plastics maʻamau ka incineration a me ka cremation, e hopena ana i ka nui o nā kinoea ʻōmaʻomaʻo i hoʻokuʻu ʻia i ka lewa, ʻoiai ua kanu ʻia nā plastics polylactic acid i loko o ka lepo no ka degradation, a ʻo ke kalapona dioxide i hana ʻia e komo pololei i loko o nā mea organik lepo a i ʻole e omo ʻia e nā mea kanu, ʻaʻole e hoʻokuʻu ʻia i ka lewa a ʻaʻole e hoʻoulu i ka hopena ʻōmaʻomaʻo.
