Māhele mea biodegradable

I nā makahiki i hala iho nei, ua loaʻa i ka haʻiʻōlelo e pili ana i nā mea hoʻomau i ka manawa like ʻole, e like me ka ulu ʻana o ka ʻike i nā hopena kaiaola e pili ana i nā plastics maʻamau. Ua puka mai nā mea biodegradable ma ke ʻano he kukui o ka manaolana, e hoʻokomo ana i ke ʻano o ka hoʻokele waiwai pōʻai a me ka hoʻohana pono ʻana i nā kumuwaiwai.

1.PHA

ʻO nā polyhydroxyalkanoates (PHA) nā polymers biodegradable i hoʻohui ʻia e nā microorganism, maʻamau maʻamau, ma lalo o nā kūlana kikoʻī. Hoʻokumu ʻia me nā monomers hydroxyalkanoic acid, kaulana ʻo PHA no kona biodegradability, hoʻololi hou ʻia mai nā mea kanu mea kanu, a me nā waiwai waiwai. Me nā noi mai ka hoʻopili ʻana a hiki i nā mea lapaʻau, hōʻike ʻo PHA i kahi koho eco-friendly e hoʻohiki ai i nā plastics maʻamau, ʻoiai ke kū nei i nā luʻina e hoʻomau nei i ka uku-pono a me ka hana nui.

2.PLA

ʻO ka Polylactic Acid (PLA) kahi thermoplastic biodegradable a bioactive i loaʻa mai nā kumuwaiwai hou e like me ka starch kulina a i ʻole ke kō. ʻIke ʻia no kona ʻano alohilohi a me ka crystalline, hōʻike ʻo PLA i nā waiwai mechanical mahalo. Hoʻohana nui ʻia i nā noi like ʻole, e komo pū ana i ka ʻeke, textiles, a me nā mea biomedical, mahalo ʻia ʻo PLA no kona biocompatibility a me ka hiki ke hōʻemi i ka hopena o ke kaiapuni. Ma ke ʻano he ʻokoʻa hoʻomau i nā plastics kuʻuna, pili ʻo PLA me ka ulu ʻana o ka manaʻo nui i nā mea eco-friendly i nā ʻoihana like ʻole. Hoʻomaopopo ia i ka pōʻaiapuni ma ke ʻano a he mea polymer ʻōmaʻomaʻo.

3.Selulose

Cellulose, i loaʻa mai i nā paia o nā mea kanu, he mea versatile e hoʻonui nei i ka nānā ʻana i ka ʻoihana paʻi. Ma ke ʻano he kumuwaiwai hou a nui hoʻi, hāʻawi ʻo cellulose i kahi koho hoʻomau i nā mea hoʻopili maʻamau. No loko mai o ka pulp lāʻau, pulupulu, a i ʻole nā ​​koena mahiʻai, hāʻawi ʻia ka pahu cellulose-based i nā pono he nui. Hiki ke hoʻolālā ʻia kekahi mau ʻano hoʻohālikelike e lilo i compostable, e kōkua ana i ka hōʻemi ʻana i ka ʻōpala kaiapuni.

4.PPC

ʻO ka Polypropylene Carbonate (PPC) kahi polymer thermoplastic e hoʻohui i nā waiwai o ka polypropylene me nā mea o ka polycarbonate. He mea bio-based a biodegradable, e hāʻawi ana i kahi ʻokoʻa pili i ke kaiapuni i nā plastics kuʻuna. Loaʻa ka PPC mai ka carbon dioxide a me ka propylene oxide, e hana ia i kahi koho hou a hoʻomau.Hoʻolālā ʻia ʻo PPC e biodegradable ma lalo o kekahi mau kūlana, e ʻae iā ia e wāwahi i loko o nā ʻāpana kūlohelohe i ka wā lōʻihi, e hāʻawi ana i ka hopena o ke kaiapuni.

5.PHB

ʻO ka Polyhydroxybutyrate (PHB) kahi polyester biodegradable a me bio-based no ka ʻohana polyhydroxyalkanoates (PHAs). Hoʻohui ʻia ʻo PHB e nā microorganism like ʻole he mea mālama ikehu. He mea kaulana ia no kona biodegradability, renewable sourcing, a me ke ʻano thermoplastic, e hoʻolilo iā ia i moho hoʻohiki i ka ʻimi ʻana i nā mea ʻokoʻa hoʻomau i nā plastics kuʻuna. He mea biodegradable ka PHB, ʻo ia hoʻi, hiki ke wāwahi ʻia e nā microorganism ma nā ʻano kaiapuni, e hāʻawi ana i ka hoʻemi ʻana i ka hopena o ke kaiapuni i hoʻohālikelike ʻia me nā plastic non-biodegradable.

6. Mākaʻikaʻi

Ma ke ʻano o ka hoʻopili ʻana, hana nui ka starch ma ke ʻano he mea hoʻomau a biodegradable, e hāʻawi ana i nā mea ʻokoʻa pili i ke kaiapuni i nā plastik maʻamau. Hoʻokumu ʻia mai nā kumu mea kanu, hoʻopili ʻia ka hoʻopili ʻana i ka starch-based me ka hoʻoikaika honua e hōʻemi i ka hopena o ke kaiapuni o nā mea hoʻopili.

7.PBAT

ʻO ka PBAT kahi polymer biodegradable a compostable no ka ʻohana aliphatic-aromatic copolyesters. Hoʻolālā ʻia kēia mea maʻalahi no ka hoʻoponopono ʻana i nā pilikia kaiapuni e pili ana i nā plastics kuʻuna, e hāʻawi ana i kahi koho hoʻomau. Hiki ke loaʻa ka PBAT mai nā kumuwaiwai hou, e like me nā meaʻai mea kanu. Hoʻopili kēia ʻano hoʻololi hou me ka pahuhopu e hōʻemi i ka hilinaʻi ʻana i nā kumuwaiwai fossil palena. A ua hoʻolālā ʻia e biodegrade ma lalo o nā kūlana kaiapuni. Hoʻohiolo nā microorganisms i ka polymer i nā huahana kūlohelohe, e hāʻawi ana i ka hōʻemi ʻana i ka ʻōpala plastik.

PBAT

ʻO ka hoʻokomo ʻana i nā mea biodegradable e hōʻailona ana i kahi neʻe nui i nā hana hoʻomau i nā ʻoihana like ʻole. ʻO kēia mau mea, i loaʻa mai nā kumuwaiwai hou, loaʻa ka mana kūlohelohe e hoʻoheheʻe maoli, e hōʻemi ana i ka hopena o ke kaiapuni. ʻO nā hiʻohiʻona kaulana ʻo Polyhydroxyalkanoates (PHA), Polylactic Acid (PLA), a me Polypropylene Carbonate (PPC), kēlā me kēia hāʻawi ʻana i nā waiwai kūʻokoʻa e like me ka biodegradability, renewable sourcing, a me ka versatility. Hoʻopili ʻia ka hoʻopaʻa ʻana i nā mea biodegradable me ka hoʻoikaika honua no nā mea ʻē aʻe e pili ana i ka kaiaola i nā plastik kahiko, e hoʻoponopono ana i nā hopohopo e pili ana i ka pollution a me ka pau ʻana o nā kumuwaiwai. Loaʻa kēia mau mea i nā noi i loko o ka ʻeke, textiles, a me nā mea lapaʻau, e hāʻawi ana i kahi pōʻai pōʻai kahi i hoʻolālā ʻia ai nā huahana me ko lākou noʻonoʻo ʻana i ka hopena o ke ola. ʻOiai nā paʻakikī e like me ke kumukūʻai kūpono a me ka hana nui, ʻo ka noiʻi ʻana a me ka holomua ʻenehana e manaʻo e hoʻomaikaʻi i ka hiki ke ola o nā mea biodegradable, e hoʻoulu i ka wā e hiki mai ana.
