He ʻeke plastik i hana ʻia me ka plastic degradable:
1. Degradable plastics:
ʻO ka plastic degradable e pili ana i ka nui o nā mea hoʻohui (e like me ka starch, starch i hoʻololi ʻia a i ʻole cellulose, photosensitizers, biodegradants, etc.) i hoʻohui ʻia i loko o ke kaʻina hana e hōʻemi i kona kūpaʻa a laila e hoʻohaʻahaʻa maʻalahi i ke kaiapuni kūlohelohe.
2. Hoʻohālikelike:
Hoʻokaʻawale ʻia nā plastic degradable i ʻehā mau ʻāpana:
①Photo degradable plastic
I ka hoʻokomo ʻana i ka photosensitizer i loko o nā plastics, ua hoʻoheheʻe ʻia nā plastics ma lalo o ka lā. No ka hanauna mua o nā plastics degradable, a ʻo kona hemahema ʻo ia ka paʻakikī o ka wā hoʻohaʻahaʻa e wānana ma muli o nā loli o ka lā a me ke aniau, no laila ʻaʻole hiki ke hoʻomalu ʻia ka manawa degradation.
②Pila hiki ke hoʻoheheʻe ʻia
ʻO ka hopena i makemake ʻia he plastic i hiki ke hoʻopiha ʻia ma ke ʻano he kahua lāʻau molecular group. Me ka biotechnology hou, ua hoʻonui ʻia ka nānā ʻana i nā plastic biodegradable, i lilo i mea hoʻomohala o ka noiʻi a me ka hoʻomohala ʻana.
③Pila māmā/biodegradable
ʻO kahi ʻano plastic e hoʻohui i ka photodegradation a me nā microorganisms, loaʻa iā ia nā hiʻohiʻona o ka māmā a me nā microorganism degradable plastics i ka manawa like.
④Pila hoʻoheheʻe wai
E hoʻohui i nā mea hoʻoheheʻe wai i nā plastics, hiki ke hoʻoheheʻe ʻia i ka wai ma hope o ka hoʻohana ʻana. Hoʻohana nui ʻia ia i nā mea lapaʻau a me nā mea hoʻomaʻemaʻe (e like me nā mīkina lima lapaʻau), kahi kūpono no ka luku a me ka disinfection.
3.Introduction:
Ua hōʻike ʻia nā hoʻāʻo e hoʻomaka ana ka hapa nui o nā plastic degradable e ʻemi, e lilo ke kaumaha, e nalowale ka ikaika, a nahā liʻiliʻi ma hope o 3 mau mahina o ka hoʻolaha ʻana i ke kaiapuni ākea. Inā kanu ʻia kēia mau ʻāpana i loko o ka ʻōpala a i ʻole ka lepo, ʻaʻole ʻike ʻia ka hopena degradation.
