Nā Mea Hoʻoemi Bio-degradable
ʻOiai e hoʻokumu ana i ka moʻomeheu hou, lawe mai nā ʻano huahana plastik āpau i ka haumia keʻokeʻo.He mea paʻakikī ke hoʻohana hou ʻana i nā kīʻaha kīʻaha, nā huahana plastic disposable a me nā kiʻi ʻoniʻoni mahiʻai, a ʻo kā lākou hana lapaʻau ʻo ka incineration a me ke kanu ʻana.ʻO ka hoʻoulu ʻana e hoʻopuka i nā kinoea ʻino a hoʻohaumia i ke kaiapuni.ʻAʻole hiki ke hoʻopau ʻia ka polymer i loko o ka ʻāina e nā microorganism no ka manawa pōkole a hoʻohaumia i ke kaiapuni.Aia ke koena kiʻiʻoniʻoni i loko o ka lepo, kahi e keʻakeʻa ai i ka ulu ʻana o nā aʻa hua a me ka absorption o ka wai a me nā meaʻai, hoʻemi i ka permeability o ka lepo, a alakaʻi i ka hōʻemi ʻana i ka hua.Hiki i nā holoholona ke make i ke keʻakeʻa ʻana o ka ʻōpū ma hope o ka ʻai ʻana i ka ʻili plastik.ʻO nā ʻupena lawaiʻa synthetic a me nā laina i nalowale a haʻalele ʻia paha i ke kai ua hoʻopōʻino nui ʻia i ke ola kai, no laila he mea nui e kākoʻo i ka ʻai ʻōmaʻomaʻo a hoʻoikaika i ka pale o ke kaiapuni.ʻO nā mea biodegradable e like me ke ʻano e like me nā huahana ʻenehana kiʻekiʻe a me nā huahana palekana kaiapuni ke lilo nei i wahi wela no ka noiʻi a me ka hoʻomohala ʻana.
Hoʻokahi mea biodegradable loa, e like me ka polymer cellulose maoli, polycaprolactone synthetic, a me nā mea ʻē aʻe.② Ma muli o ka hana biochemical microbial, enzyme catalysis a i ʻole acid-base catalysis o nā hydrolysis like ʻole;③ ʻO ka hoʻohaʻahaʻa kaulahao o nā radical manuahi i hoʻokumu ʻia e nā kumu ʻē aʻe.
ʻO ka ʻāpana ʻē aʻe he mau mea biodisintegrating, e like me ka starch a me ka polyethylene blends, nona ka decomposition ma muli o ka luku ʻana i nā mea hoʻohui a me ka nāwaliwali o ke kaulahao polymer, e hoʻohaʻahaʻa ai i ke kaumaha o ka polymer a hiki i ka hiki ke hoʻopau ʻia e ia. microorganisms, a hope loa i carbon dioxide (CO2) a me ka wai.
ʻO ka hapa nui o ka bio-Hoʻohui ʻia nā mea disintegrating me ka polyethylene a me ka polystyrene ma ka hoʻohui ʻana i ka starch a me ka photosensitizer.Ua hōʻike ʻia nā haʻawina e pau ana nā ʻeke plastik biodegradable i hoʻokumu ʻia i ka starch i loko o ka pae ʻāina, me ka launa ʻole ʻana me ka lā, ʻoiai inā he pōʻino olaola, ʻo ka biodegradation ka nui.-hoʻohaʻahaʻa.Hōʻike kekahi hōʻike manawa ʻaʻole ʻike ʻia ka hōʻino ʻana o nā ʻeke ʻōpala, ʻaʻohe pōʻino kūlohelohe i nā ʻeke ʻōpala.
No ka hoʻoponopono ʻana i ka pollution kaiapuni, ʻoiai ʻoi aku ka maikaʻi o nā plastics based starch ma mua o nā huahana plastic disposable, akā hoʻohana mau i ka polyethylene a i ʻole nā mea polyester non-biodegradable e like me nā mea maka, hiki ke lilo i mau mea semi-degradable, ma kahi o ka starch i hoʻohui ʻia hiki ke hoʻohaʻahaʻa ʻia. ʻO ke koena nui o ka polyethylene a i ʻole ka polyester e mau nō a ʻaʻole hiki ke hoʻoheheʻe ʻia, hoʻoheheʻe wale ʻia i ʻāpana, ʻaʻole hiki ke hana hou ʻia.No laila, lilo nā mea biodegradable piha i ka manaʻo o ka noiʻi ʻana i nā mea degradable.
