ʻO Bioplastic kahi ʻano like ʻole o nā mea olaola a hoʻohaʻahaʻa i ke ʻano me ka ʻole o nā pilikia. Hoʻopili kēia pūʻulu i nā mea hana i hoʻohana ʻia i nā ʻano āpau. Hana ʻia kēlā ʻano mea mai ka biomass (microorganisms a me nā mea kanu), a he ʻoluʻolu kūlohelohe. Ma hope o ka hoʻohana ʻia ʻana i ke kūlohelohe, decompose lākou i compost, wai a me carbon dioxide. Hana ʻia kēia hana ma lalo o ka mana o nā kūlana o ke kaiapuni. ʻAʻole ia e hoʻopili ʻia e ka helu o ka biodegradation. ʻO kahi laʻana, ʻo ka plastic i hana ʻia mai nā ʻaila ʻaila i ʻoi aku ka wikiwiki ma mua o ka plastic-bio.
Hoʻonohonoho bioplastic
Hoʻokaʻawale ʻia nā ʻano bioplastics like ʻole i nā pūʻulu aʻe.
- Pūʻulu mua. Hoʻopili pū ʻia me nā plastics o nā mea ola a hapa a me nā mea ola, ʻaʻohe o lākou hiki ke biodegrade. ʻO PE, PP a me PET kēia. Hoʻopili pū kēia i nā biopolymers - PTT, TPC-ET
- Ka lua. Hoʻopili kēia pūʻulu i nā plastics biodegradable o biodegradability. ʻO PLA, PBS a me PH
- Pūʻulu ʻekolu. Loaʻa nā mea o kēia hui mai nā minela, no laila he biodegradable lākou. ʻO PBAT kēia
Kuhi ka International Organization of Chemistry i ka manaʻo o "bioplastic" ʻo kēia huaʻōlelo e alakaʻi hewa nei i ka poʻe. ʻO ka ʻoiaʻiʻo ʻo ka poʻe ʻike liʻiliʻi e pili ana i nā waiwai a me nā pono o nā bioplastics hiki ke ʻae iā ia ma ke ʻano he ʻano pilikino. ʻOi aku ka pili o ka hoʻopili ʻana i ka manaʻo o "polymers of biological origin". ʻAʻohe kuhi o nā pono kaiapuni i kēia inoa, akā koʻikoʻi wale i ke ʻano o nā mea. No laila, ʻoi aku ka maikaʻi o nā bioplastics ma mua o nā polym synthetic synthetic.
ʻO ka mākeke bioplastics hou
I kēia lā ke pani ʻia nei ka mākeke bioplastic e nā pono like ʻole i hana ʻia mai nā kumuwaiwai hou. Kaulana nā meaolaola i hana ʻia mai ke kō a me ke kō. Hāʻawi lākou i ka starch a me ka cellulose, ka mea, ʻoiaʻiʻo, nā polymers kūlohelohe e hiki ai ke loaʻa ka palekiko.
Loaʻa nā bioplastics kulina mai nā ʻoihana e like me Metabolix, NatureWorks, CRC, a me Novamont. Hoʻohana ʻia ke kō e hana i nā mea mai ka hui Braskem. Ua lilo ka aila Castor i mea maka no nā bioplastics i hana ʻia e Arkema. Hana ʻia ʻo Polylactic acid e Sanyo Mavic Media Co Ltd. hana i kahi CD biodegradable. Hana nā Biopolymers Rodenburg i nā bioplastics mai kaʻuala. I kēia manawa, ke koi ʻia nei ka hana ʻana o nā bioplastics mai nā mea maka hou i makemake ʻia, ke hōʻike mau nei nā ʻepekema i nā laʻana hou a me nā hanana i kēia ʻaoʻao.
