Hoʻomohala a me ka hoʻohana ʻana i nā plastik biodegradable

ʻO ka wehewehe ʻana o nā plastic biodegradable, ʻo ia ke kuhikuhi i ke ʻano, e like me ka lepo, ke one, ka wai wai, ka wai wai, kekahi mau kūlana e like me ka composting a me nā kūlana anaerobic digestion, ka hoʻohaʻahaʻa ʻia e ka hana microbial o ke ʻano o ke ʻano, a ma hope. decomposed i carbon dioxide (CO2) a me/aiʻole methane (CH4), wai (H2O) a me ka mineralization o ka mea i loko o ka paʻakai inorganic, a me ka biomass hou (e like me ke kino o nā microorganisms, etc.) o ka plastic.

Ka hoʻohālikelike ʻana o kekahi mau plastic biodegradable maʻamau

ʻO ka huahana a me ka hāʻawi ʻana i nā plastic biodegradable

Wahi a ka ʻikepili hou loa i hoʻokuʻu ʻia e ka European Bioplastics Association i Kepakemapa 2019, ʻo Sepatemaba 2019, ʻo ka mana hana makahiki honua o nā plastic biodegradable.2144,000 tona;

ʻO ka PLA (polylactic acid).628,000 tona, helu helu no29.3%;

ʻO ka PBAT (polyadipic acid/butylene terephthalate).606,800 tona, helu helu no28.3%;

ʻO ka plastic degradable ma muli o ka starch96.27 tona, helu helu no44.9%o ka hiki honua biodegradable plastic.

Ka hāʻawi honua ʻana i ka hiki ke biodegradable plastics i 2019

(Uni: %)

Ke koi nei i lalo o ka honua no nā plastic biodegradable i 2019

(Uni: %)

Kūlana biodegradable

ʻO ka hoʻohaʻahaʻa lepo

Hiki ke hoʻohaʻahaʻa ʻia ka PBAT, PHA, PCL a me PBS ma hope o 5 mahina.

He lohi ka emi ʻana o nā mea PLA, 0.23% wale nō i ka makahiki.

Hiki ke hoʻohaʻahaʻa loa ʻia ka PLA a me ka PKAT ma kahi o ka hapalua makahiki ma hope o ka hui ʻana.

ʻO ka hoʻohaʻahaʻa wai

Hiki ke hoʻohaʻahaʻa loa ʻia ka PHA a me ka PKAT i nā lā 30 ~ 60 ma lalo o ke kūlana wai kai simulated o 25 ℃ ± 3 ℃.
