Nā ʻoiaʻiʻo e pili ana i ka lula

1. He aha ka palapalai hoʻohaʻahaʻa?

ʻO ka palekiko hoʻohaʻahaʻa kahi manaʻo nui. He wā ia o ka manawa a loaʻa i hoʻokahi a ʻoi paha nā ʻanuʻu ma lalo o nā kūlana kaiapuni i ʻōlelo ʻia, e hopena ana i nā hoʻololi nui i ka hanana kemika o nā mea, nalo o kekahi mau waiwai (e like me ka pono, ka mole mole, ka hana a me ka ikaika mechanical) a / a haki pālolo.

2. He aha ka plastic biodegradable?

ʻO nā meaola biodegradable he plastics i hiki ke hoʻopau ʻia e ka hana a nā meaola ola, nā microbes maʻamau, i loko o ka wai, carbon dioxide, a me biomass. Hana pinepine ʻia nā meaola biodegradable me nā mea pono hou, nā meaola micro, nā petrochemical, a i ʻole nā ​​hui pū o nā mea ʻekolu.

3. He aha kahi meaola olaola?

ʻO nā mea biodegradable e hoʻopili me nā mea polymer biodegradable kūlohelohe e like me cellulose, starch, pepa, a pēlā aku, a me nā plastics biodegradable i loaʻa ʻia e ka bio-synthesity a i ʻole synthes kemika.

ʻO ke ea biodegradable e pili ana i ka paʻakai inorganic mineralized a me ka biomass hou (e like me nā kino make microbial, a me nā mea ʻē aʻe) nona ka hoʻohaʻahaʻa e hoʻokumu ʻia e ka hana o nā microorganism i ke ʻano ma lalo o nā kūlana kūlohelohe e like me ka lepo a me / a one, a / a i ʻole nā ​​ʻano kikoʻī e like me nā kūlana composting a i ʻole ka anaerobic digestion a i ʻole nā ​​wai wai moʻomeheu wai, a laila e hoʻoliʻiliʻi loa ʻia i carbon dioxide (CO2) a i ʻole / a me methane (CH4), wai (H2O) a me nā mea i loaʻa i loko.

Pono e hoʻomaopopo ʻia i kēlā me kēia ʻano meaola biodegradable, e like me ka pepa, koi i kekahi mau ʻano kaiapuni no kona hoʻohaʻahaʻa. Inā ʻaʻohe ona kūlana hoʻohaʻahaʻa, keu hoʻi nā kūlana ola o nā microorganism, e lohi loa kona hoʻohaʻahaʻa; i ka manawa like, ʻaʻole hiki ke hoʻohaʻahaʻa wikiwiki i kēlā me kēia ʻano o nā meaola biodegradable ma lalo o nā kūlana kaiapuni. No laila, koi ʻia mākou e hoʻoholo inā he biodegradable kahi mea ma o ke aʻo ʻana i nā kūlana o ke kaiapuni a puni a me ke kālailai ʻana i ke ʻano o nā mea ponoʻī.

4. Nā ʻano ʻē aʻe o nā plastics biodegradable

Wahi a ke ʻano o nā mea maka i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia ka palu biodegradable i ʻehā mau ʻāpana. ʻO ka mahele mua kahi palolo e hoʻoponopono pololei ʻia mai nā mea kūlohelohe. Ma ka mākeke i kēia manawa, hiki ke hana ʻia i ka ea biodegradable, i hana ʻia e nā polymers kūlohelohe me ka starch thermoplastic, biocellulose a me polysaccharides a pēlā aku. ʻO ka mahele ʻelua kahi polymer i kiʻi ʻia e ka fermentation microbial a me ka synthes kemika, e like me ka polylactic acid (PLA), a pēlā aku. ʻO ka mahele ʻekolu he polymer, kahi i hoʻopili pono ʻia e nā mea microorganism, e like me polyhydroxyalkanoate (PHA), a pēlā aku. ʻO ka mahele ʻehā kahi plastic biodegradable i loaʻa i ka hoʻopili ʻana i nā mea i haʻi ʻia ma mua a i ʻole ka hoʻohui ʻana i nā synthetics kemika.
