He aha ka ʻeke plastik pili i ke kaiapuni?

He pōkole nā ​​ʻeke plastik pili i ke kaiapuni no nā ʻano ʻeke plastik biodegradable. Me ka hoʻomohala ʻana i ka ʻenehana, ʻike ʻia nā mea like ʻole e hiki ke pani i nā plastic PE kuʻuna, me nā PLA, PHA, PBA, PBS a me nā mea polymer ʻē aʻe. Hiki ke pani i nā ʻeke plastik PE maʻamau. Ua hoʻohana nui ʻia nā ʻeke plastik pale kaiapuni: nā ʻeke kūʻai kūʻai kūʻai nui, nā ʻeke mālama hou i ka roll-to-roll, a me nā kiʻiʻoniʻoni mulch ua hoʻohana nui ʻia ma Kina. Ua hoʻohana ʻo Jilin Province i ka PLA (polylactic acid) ma kahi o nā ʻeke plastik kahiko, a loaʻa nā hopena maikaʻi. Ma Sanya City, Hainan Province, ua hoʻohana nui ʻia nā ʻeke plastik biodegradable e pili ana i ka starch i nā ʻoihana e like me nā hale kūʻai a me nā hōkele.
ʻO ka ʻōlelo maʻamau, ʻaʻohe ʻeke plastik maikaʻi loa. Hiki ke hoʻohaʻahaʻa wale ʻia kekahi mau ʻeke plastik ma hope o ka hoʻohui ʻana i kekahi mau meaʻai. ʻO ia hoʻi, biodegradable plastic. Hoʻohui i kahi nui o nā mea hoʻohui (e like me ka starch, starch i hoʻololi ʻia a i ʻole cellulose ʻē aʻe, photosensitizers, biodegradants, a me nā mea ʻē aʻe.) He 19 mau ʻāpana e hoʻomohala a hana i nā plastic biodegradable ma Beijing. Ua hōʻike ʻia nā hoʻāʻo ʻana e hoʻomaka ana ka hapa nui o nā plastic degradable e lilo i mea lahilahi, lilo ke kaumaha, a nalowale ka ikaika ma hope o ka ʻike ʻia ʻana i ke kaiapuni maʻamau no 3 mau mahina, a ʻoki liʻiliʻi i nā ʻāpana. Inā kanu ʻia kēia mau ʻāpana i loko o ka ʻōpala a i ʻole ka lepo, ʻaʻole maopopo ka hopena degradation. ʻEhā mau hemahema i ka hoʻohana ʻana i nā plastic degradable: ʻo ka ʻai ʻana i ka meaʻai hou aku; ʻo ka mea ʻē aʻe, ʻaʻole hiki i ka hoʻohana ʻana i nā huahana plastic degradable ke hoʻopau loa i ka "pollution hiʻohiʻona"; ʻO ke kolu ʻo ia ma muli o nā kumu ʻenehana, ʻaʻole hiki i ka hoʻohana ʻana i nā huahana plastic degradable ke hoʻopau piha i ka hopena o ke kaiapuni "Potential hazards"; ʻO ka hā, he paʻakikī ke hana hou ʻana i nā plastic degradable no ka mea aia nā mea hoʻohui kūikawā.
ʻO ka ʻoiaʻiʻo, ʻo ka mea ʻoi loa ka pilikua kaiapuni ʻo ka hoʻohana ʻana i nā ʻeke plastik a i ʻole nā ​​ʻeke paʻa paʻa e hōʻemi i ka nui o ka hoʻohana. I ka manawa like, hiki ke hana hou ʻia e ke aupuni e hōʻemi i ka pollution kaiapuni.
