Me ka hoʻonui ʻana i ka ʻike i ka hopena o ke kaiapuni o ka ʻōpala plastik a me ke kaumaha i hoʻonui ʻia e pili ana i kona hoʻolei ʻana, aia kahi māka e hoʻohana i ka hana hou ma kahi o ka plastic puʻupaʻa inā hiki.No ka nui o nā mea hoʻohana i hana ʻia me ka plastic, ua hoʻāla kēia i ka nīnau inā hiki ke hoʻololi i nā plastics i hana hou ʻia i loko o ka lab, a inā pēlā, pehea ka hiki.
Hoʻohana ka poʻe ʻepekema i nā mea i hoʻohana ʻia i loko o ka nui o nā huahana i loko a puni ka lab - me nā paipu (Nā paipu Cryovial,Nā paipu PCR,Nā paipu Centrifuge), Microplates(palapala moʻomeheu,24,48,96 papa punawai hohonu, ʻO nā pale PCR), ʻōlelo paipai pipette(Automated or Universal tips), petri dishes,Nā ʻōmole Reagent,a oi aku.No ka loaʻa ʻana o nā hopena kūpono a hilinaʻi hoʻi, pono nā mea i hoʻohana ʻia i nā mea hoʻohana i nā kūlana kiʻekiʻe loa i ka wā e pili ana i ka maikaʻi, kūlike, a me ka maʻemaʻe.He koʻikoʻi nā hopena o ka hoʻohana ʻana i nā mea waiwai ʻole: hiki ke lilo ka ʻikepili mai kahi hoʻokolohua holoʻokoʻa, a i ʻole ka pūʻulu o nā hoʻokolohua, hiki ke lilo i mea waiwai ʻole me ka pau ʻole o ka pau ʻana a i ʻole ke kumu o ka haumia.No laila, hiki anei ke hoʻokō i kēia mau kūlana kiʻekiʻe me ka hoʻohana ʻana i nā plastic recycled?No ka pane ʻana i kēia nīnau, pono mākou e hoʻomaopopo mua i ka hana ʻana o kēia.
Pehea e hana hou ʻia ai nā plastik?
ʻO ke ao holoʻokoʻa, ʻo ka hana hou ʻana o nā plastics kahi ʻoihana e ulu nei, i alakaʻi ʻia e ka hoʻonui ʻana i ka ʻike i ka hopena o ka ʻōpala plastic i ka honua honua.Eia nō naʻe, nui nā ʻano like ʻole o nā ʻōnaehana hana hou e hana ana ma nā ʻāina like ʻole, ma ke ʻano o ka nui a me ka hoʻokō.I Kelemānia, no ka laʻana, ka papahana Green Point, kahi e uku ai nā mea hana i ke kumukūʻai o ka hana hou ʻana i ka plastic i kā lākou huahana, ua hoʻokō ʻia i ka makahiki 1990 a ua hoʻonui ʻia i nā wahi ʻē aʻe o ʻEulopa.Eia nō naʻe, ma nā ʻāina he nui, ʻoi aku ka liʻiliʻi o ka hana ʻana i nā plastics, ma muli o nā pilikia he nui e pili ana i ka hana hou ʻana.
ʻO ka luʻi nui i ka hana hou ʻana i ka plastic, ʻo ia ka mea ʻoi aku ka nui o nā mea kemika ma mua o ke aniani.ʻO ia ke ʻano o ka loaʻa ʻana o kahi mea hana hou, pono e hoʻokaʻawale ʻia ka ʻōpala plastic i nā ʻāpana.Loaʻa i nā ʻāina a me nā ʻāina ʻē aʻe kā lākou mau ʻōnaehana maʻamau no ka hoʻokaʻawale ʻana i nā ʻōpala recyclable, akā he nui nā mea like ʻole no ka plastics:
- Polyethylene terephthalate (PET)
- Polyethylene kiʻekiʻe (HDPE)
- Polyvinyl chloride (PVC)
- Polyethylene haʻahaʻa haʻahaʻa (LDPE)
- Polypropylene (PP)
- Polystyrene (PS)
- 'ē aʻe
Nui nā ʻokoʻa i ka maʻalahi o ka hana hou ʻana o kēia mau ʻano like ʻole.No ka laʻana, maʻalahi ka hana hou ʻana o nā hui 1 a me 2, akā ʻaʻole i hana hou ʻia ka ʻāpana 'ē aʻe' (hui 7).Ma waho o ka helu o ka hui, hiki ke ʻokoʻa loa nā plastik recycled mai ko lākou mau hoa puʻupaʻa ma ke ʻano a i ʻole ka maʻemaʻe a me nā waiwai mechanical.ʻO ke kumu o kēia, ʻoiai ma hope o ka hoʻomaʻemaʻe ʻana a me ka hoʻokaʻawale ʻana, mau ka haumia, mai nā ʻano plastics a i ʻole nā mea e pili ana i ka hoʻohana mua ʻana o nā mea.No laila, ʻo ka hapa nui o nā plastics (ʻaʻole like me ke aniani) e hana hou ʻia i hoʻokahi manawa a ʻokoʻa nā mea hana i hoʻohana ʻia ma mua o ko lākou mau hoa puʻupaʻa.
He aha nā huahana e hiki ke hana ʻia mai nā plastic recycled?
ʻO ka nīnau no nā mea hoʻohana lab: Pehea e pili ana i nā mea hoʻohana lab?Loaʻa nā mea hiki ke hana i nā plastic-grade plastic mai nā mea hana hou?No ka hoʻoholo ʻana i kēia, pono e nānā pono i nā waiwai i manaʻo ʻia e nā mea hoʻohana mai nā mea hoʻohana lab a me nā hopena o ka hoʻohana ʻana i nā mea substandard.
ʻO ka mea nui o kēia mau waiwai he maʻemaʻe.Pono e hoʻemi ʻia nā haumia i loko o ka plastik i hoʻohana ʻia no nā mea hoʻohana lab no ka mea hiki iā lākou ke lele i waho o ka polymer a i loko o kahi laʻana.Hiki i kēia mau mea i kapa ʻia nā leachable ke loaʻa i nā hopena hiki ʻole i ka manaʻo, no ka laʻana, nā moʻomeheu o nā cell ola, me ka hoʻopili ʻana i nā ʻenehana analytical.No kēia kumu, koho mau nā mea hana o nā mea hoʻohana lab i nā mea me nā mea hoʻohui liʻiliʻi.
I ka hiki ʻana mai i nā plastic recycled, ʻaʻole hiki i nā mea hana ke hoʻoholo i ke kumu kūpono o kā lākou mau mea a no laila nā mea haumia i loaʻa.A ʻoiai ke hoʻoikaika nui nei nā mea hana i ka hoʻomaʻemaʻe ʻana i nā plastic i ka wā o ke kaʻina hana hou ʻana, ʻoi aku ka haʻahaʻa o ka maʻemaʻe o nā mea hana hou ma mua o nā plastik puʻupaʻa.No kēia kumu, kūpono nā plastic recycled no nā huahana i hoʻohana ʻole ʻia e nā liʻiliʻi liʻiliʻi.ʻO nā mea hoʻohālike e pili ana i nā mea hana no ke kūkulu ʻana i nā hale a me nā alanui (HDPE), nā lole (PET), a me nā mea cushioning for packaging (PS)
Eia nō naʻe, no nā mea hoʻohana lab, a me nā noi koʻikoʻi ʻē aʻe e like me ka nui o nā mea pili i ka meaʻai, ʻaʻole lawa nā pae maʻemaʻe o nā kaʻina hana hou i kēia manawa e hōʻoiaʻiʻo i nā hopena hilinaʻi a hiki ke hana hou ʻia i ka lab.Eia kekahi, he mea nui ka ʻike o ka optical kiʻekiʻe a me nā waiwai mechanical i ka hapa nui o nā mea hoʻohana lab, a ʻaʻole i ʻoluʻolu kēia mau koi i ka wā e hoʻohana ai i nā plastic recycled.No laila, ʻo ka hoʻohana ʻana i kēia mau mea hiki ke alakaʻi i nā hopena maikaʻi ʻole a i ʻole nā mea maikaʻi ʻole i ka noiʻi, nā hewa i nā noiʻi forensic, a me nā maʻi lapaʻau hewa ʻole.
Ka hopena
ʻO ka hana hou ʻana i ka plastik kahi ʻano i hoʻokumu ʻia a ulu nui i ka honua e loaʻa ka hopena maikaʻi a mau loa i ke kaiapuni ma o ka hōʻemi ʻana i ka ʻōpala plastik.I loko o ke kaiapuni lab, hiki ke hoʻohana ʻia ka plastic recycled i nā noi i hilinaʻi ʻole ʻia i ka maʻemaʻe, no ka laʻana i ka ʻeke.Eia nō naʻe, ʻaʻole hiki ke hoʻokō ʻia nā koi no nā mea hoʻohana lab ma ke ʻano o ka maʻemaʻe a me ke kūpaʻa ʻana e nā hana hana hou o kēia manawa, a no laila pono e hana ʻia kēia mau mea mai nā plastik puʻupaʻa.
