Bioplastics
Ma muli o ka waiwai, hiki i ka manawa o ka bioplastics e hoʻopiha piha ʻia i kahi manawa ʻokoʻa a pono e hoʻopuehu ʻia i loko o nā keʻena compost ʻoihana, kahi e hiki ai ke kiʻekiʻe o ka mahana o ka compost, a ma waena o 90 a 180 mau lā.ʻO ka hapa nui o nā kūlana honua e koi nei e hoʻohaʻahaʻa ʻia ka 60% o ke kino i loko o 180 mau lā, a me kekahi mau kūlana ʻē aʻe e kāhea ana i nā resins a i ʻole nā huahana compostable.He mea nui nō hoʻi e hoʻokaʻawale i waena o ka degradable a me ka biodegradable a me ka compostable, no ka mea, hoʻohana pinepine ʻia kēia mau huaʻōlelo.
Pākīpika biodegradable
ʻO ka plastic biodegradable kahi ʻano plastic e hoʻohaʻahaʻa ʻia e nā microorganism kūlohelohe (e like me ka bacteria, fungi, etc.) i kekahi manawa.E hoʻomanaʻo ʻaʻohe kuleana e waiho i nā "koena ʻona ʻole", ʻaʻole hoʻi i ka manawa i koi ʻia no ka biodegradation.
He mea nui hoʻi ka hana hou ʻana no ke kaiapuni, a no ia kumu, loaʻa iā mākou kahi ʻaoʻao e pili ana i nā ʻeke hana hou me nā ʻike hoihoi.
Pākīpika biodegradable
Loaʻa i nā plastic degradable nā ʻano plastic degradable a pau, me nā plastic biodegradable a me ka compostable plastics.Eia nō naʻe, hoʻohana maʻamau nā plastic non-biodegradable a i ʻole compostable i ka lepili "degradable plastic".Hoʻohana ka hapa nui o nā huahana i nā lepili plastik biodegradable, e hoʻohaʻahaʻa ʻia ma muli o ke kino a me ke kemika.ʻAʻole ʻo ka hana olaola kahi ʻāpana nui o ka hoʻohaʻahaʻa ʻana i kēia mau huahana, a i ʻole lohi loa ke kaʻina hana no ka helu ʻia ʻana he biodegradable a i ʻole compostable.
Nā ʻano plastic degradable
Ma muli o ka starch
Hana ʻia kekahi mau mea i hoʻoheheʻe ʻia mai ka mākū kulina.Pono kēia mau mea i kahi microbial kaiapuni ma mua o ka hoʻohaʻahaʻa ʻana, e like me ka pae ʻāina a i ʻole ka compost, e hoʻohaʻahaʻa loa ʻia kekahi i kēia kaiapuni, a ʻo nā mea ʻē aʻe e puncture wale nō, ʻoiai ʻaʻole e hoʻohaʻahaʻa nā mea palaki.Hiki ke hoʻopōʻino i ka lepo, nā manu a me nā holoholona hihiu ʻē aʻe a me nā mea kanu ʻē aʻe i koe.ʻOiai ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā mea hana hou, ʻaʻole lākou e hāʻawi i ke ala maikaʻi loa no ka hoʻomohala ʻana.
Aliphatic
ʻO kekahi ʻano o ka plastic degradable hoʻohana i nā polyesters aliphatic maʻamau.E like me ka starch, hilinaʻi lākou i ka hana microbial o ka compost a i ʻole nā ʻāina ʻāina ma mua o ka hoʻohaʻahaʻa ʻana.
Hiki ke paʻi kiʻi
E hoʻohaʻahaʻa lākou i ka wā e ʻike ʻia ai ka lā, akā ʻaʻole e hoʻohaʻahaʻa i loko o nā pae ʻāina, nā ʻōpala, a me nā wahi pōʻeleʻele ʻē aʻe.
ʻO ka oxygen hiki ke hoʻoheheʻe ʻia
Hoʻohaʻahaʻa ʻia nā huahana i luna e ke kaʻina degradation hydration, akā ʻo ke ʻano pono a me ka hoʻokele waiwai i ka ʻenehana hou ʻo ia ka hana ʻana i ka plastic, a ua hoʻohaʻahaʻa ʻia ka plastic e ke kaʻina degradation OXO.Hoʻokumuʻia kaʻenehana ma ka hoʻokomoʻana i kahi liʻiliʻi o nā mea hoʻohui hoʻohaʻahaʻa (maʻamau 3%) i loko o ke kaʻina hana hana maʻamau, a laila e hoʻololi i nā waiwai o ka plastic.ʻAʻole hilinaʻi ia i nā microorganism e wāwahi i nā plastics.Hoʻomaka ka hoʻohaʻahaʻa ʻana o nā plastik ma hope koke o ka hana ʻana a hoʻolalelale i ka hoʻohaʻahaʻa i ka wā e ʻike ʻia ai i ka wela, ka māmā a i ʻole ke kaomi.ʻAʻole hiki ke hoʻohuli ʻia kēia kaʻina hana a hoʻomau a hiki i ka hoʻemi ʻana o ka mea i carbon dioxide a me ka wai.No laila, ʻaʻole ia e waiho i nā ʻāpana polymer petroleum i ka lepo.
