Me ka wikiwiki o ka hoʻomohala ʻana i ka ʻoihana hoʻopihapiha, ka hana hou o ka ʻenehana noi waiwai a me ka hoʻonui nui ʻana o ka manaʻo o ka mālama ʻana i ke kaiapuni o ka poʻe, ʻoi aku ka nui o ka paʻi plastik i hana ʻia i nā mea kūlohelohe. o nā ʻeke plastik kaiapuni: ʻilika hoʻopōmaikaʻi ʻia, ʻilika hiki ke hoʻopau ʻia a me ka plastik hiki ke ʻai.
ʻO ka Plastic Recycled
ʻO ka plastic recycled ka hoʻohana hou ʻana i ka plastic, ma o ka hana ʻana i ka ʻili mīkini, i mea e hoʻopau ai i ka hoʻohana hou ʻana i ka plastic.
ʻO ka plastic recycled ka mea i loaʻa hou ma hope o ka hana ʻana i ka palaka ʻōpala e ke ʻano kino a i ʻole kemika e like me ka pretreatment, melting granulation a me ka hoʻololi ʻana, ʻo ia ka hoʻohana hou ʻana i ka plastic.
ʻOi aku ka maikaʻi loa o ka plastic recycled ma mua o ke kumukūʻai waiwai hou, ʻoiai aia ma ka hana holoʻokoʻa a ʻaʻole maikaʻi nā waiwai e like me ka ikaika o nā mea hou, akā ʻaʻole pono mākou e hoʻohana i ka nui o nā huahana i hana ʻia nā waiwai a ka hana o na mea maikai a pau e hana ia, no laila ua pau i ka hailona o ka pono ole, a me ka reworked mea okoa, e like me ka like 'ole e pono ai, Pono wale e hana i kekahi hiʻona o ka hiʻona, hiki ke hana i ka huahana pili. , i ole e poho ka waiwai.
ʻO ka Plastic Degradable
ʻO nā plastic degradable e pili ana i nā plastics i hoʻohaʻahaʻa maʻalahi ʻia ma ke ʻano kūlohelohe ma muli o ka hoʻohui ʻana i kekahi mau mea hoʻohui (e like me ka starch, starch i hoʻololi ʻia a i ʻole cellulose, photosensitizer, biodegradation agent, etc.) i ke kaʻina hana.Hāʻule nā plastic degradable i ʻehā mau ʻāpana nui:
1. Biodegradable Plastic
ʻO ka maloʻo, ʻaʻole pono e pale i ka māmā, kahi ākea o nā noi, ʻaʻole hiki ke hoʻohana wale ʻia no ka kiʻiʻoniʻoni plastik mahiʻai, ʻeke ʻeke, a hoʻohana nui ʻia i ka lāʻau lapaʻau.Me ka hoʻomohala ʻana o ka biotechnology hou, ua uku nui ʻia nā plastik biodegradable a lilo i wahi wela hou i ka noiʻi a me ka hoʻomohala ʻana.
2.Photodegradable Plastic
Hoʻohui ʻia kahi photosensitizer i ka plastic e wāwahi mālie i lalo o ka lā.Aia ia i ka hanauna mua o nā plastics degradable, a ʻo kona hemahema ʻo ka hiki ʻole ke ʻike ʻia ka manawa hoʻohaʻahaʻa ma muli o ka lā a me ka hoʻololi ʻana i ke aniau, no laila ʻaʻole hiki ke mālama i ka manawa degradation.
3.Water Degradation o Plastic
Hoʻohui i ka wai absorbent mea i loko o ka plastic, ma hope o ka hoʻohana ʻana, e hoʻolei i ka wai hiki ke hoʻoheheʻe, hoʻohana nui ʻia i ka lāʻau lapaʻau a me nā mea pono olakino (e like me nā mīkina lima lapaʻau), maʻalahi e luku a me ka mālama disinfection.
4. Māmā/biodegradable Plastic
ʻO Photodegradation a me microbial hui pū ʻana o kahi papa plastic, loaʻa iā ia ka māmā a me ka microbial degradation o nā ʻano plastik.
ʻAi ʻAi
ʻO ka edible plastic kahi ʻano o ka paʻi ʻai, ʻo ia hoʻi, edible packaging, maʻamau i haku ʻia me ka starch, protein, polysaccharide, momona, mea hoʻohuihui, hoʻohana nui ʻia e like me ka plastic wrap, packaging film, high point packaging, food packaging, pastry packaging, hoʻopili ʻana i nā mea ʻala, etc.
Me ka hoʻomohala ʻana o ka ʻoihana meaʻai hou, hoʻonui mau ʻia ka ʻeke meaʻai.Ke kū nei kahi ʻano mea ʻenehana meaʻai meaʻai hou, edible packaging, hiki ke hoʻomaikaʻi i ka kūʻē ʻana ma waena o nā mea hoʻopili a me ka pale ʻana i ke kaiapuni.Hiki ke hoʻololi ʻia i mea ʻai meaʻai no nā holoholona a i ʻole nā kānaka ma hope o ka hoʻokō ʻia ʻana o ka hana o ka packaging.ʻO ka mea hoʻopili ʻai meaʻai he ʻano ʻōpala me ka ʻole o ka ʻōpala, ʻo ia ke ʻano o ka waiwai hoʻopaʻa ʻia i ka mālama kaiapuni.
