ʻO nā kīʻaha wai plastik nā mea maʻamau i hoʻohana ʻia i ko mākou ola i kēlā me kēia lā. He mea nui e koho i nā mea palekana. He ʻatikala e pili ana i nā mea palekana o nā kīʻaha wai plastik.
Ke nānā nui nei ka poʻe i ke olakino a me ka mālama ʻana i ke kaiapuni, ʻoi aku ka nui o nā mea kūʻai aku i ka nānā ʻana i ke koho ʻana o nā kīʻaha wai plastik. ʻO ka palekana kekahi o nā mea nui e noʻonoʻo ai i ke koho ʻana i kahi hue wai plastik. E hoʻolauna kēia ʻatikala i kekahi mau mea kīʻaha wai plastik maʻamau a nānā i nā pilikia palekana.
ʻO ka mea mua, ʻo ka polyethylene (PE) kahi mea kīʻaha wai plastik maʻamau. Loaʻa iā ia ke kūpaʻa haʻahaʻa haʻahaʻa a kiʻekiʻe a ʻaʻole hoʻokuʻu i nā mea ʻino. Hiki ke hoʻohana ʻia nā ʻōmole wai polyethylene e paʻa i nā mea inu wela a i ʻole ke anuanu a palekana loa a hilinaʻi. Eia kekahi, ʻo ka polyethylene he plastic recyclable a he ʻoluʻolu kaiapuni.
ʻO ka lua, ʻo ka polypropylene (PP) he ipu kīʻaha wai maʻamau. E like me ka polyethylene, hiki i ka polypropylene ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika. No laila, ʻo nā hue wai polypropylene kahi koho palekana. Pēlā nō, ʻo ka polypropylene kekahi mea i hoʻohana hou ʻia a pili i ke kaiapuni.
Eia nō naʻe, ʻaʻole kūpono paha kekahi mau mea palaka e like me nā mea kīʻaha wai. No ka laʻana, polyvinyl chloride (PVC) he plastic maʻamau, akā hiki iā ia ke hoʻokuʻu i nā mea ʻino e like me nā plasticizers. Hiki i kēia mau mea kemika ke hoʻopilikia i ke olakino kanaka. No laila, i ke koho ʻana i nā hue wai plastik, e hoʻāʻo e pale i ka hoʻohana ʻana i nā mea polyvinyl chloride.
Eia kekahi, ʻo ka polystyrene (PS) he mea palaka maʻamau, akā pili ia i nā loli wela. Hiki i ka Polystyrene ke hoʻokuʻu i nā mea ʻino i nā wela kiʻekiʻe, ʻaʻole kūpono ia no nā mea inu wela. ʻOiai ʻoi aku ka liʻiliʻi o nā hue wai polystyrene ma ke kumukūʻai, mai kahi hiʻohiʻona palekana, manaʻo mākou e koho i nā mea ʻē aʻe.
Eia kekahi, aia kahi plastic biodegradable i kapa ʻia he melamine (PLA), i hoʻohana nui ʻia i ka hana ʻana i nā kīʻaha wai plastik i nā makahiki i hala. Hoʻokumu ʻia ka PLA mai nā kumuwaiwai hou e like me ka starch kulina a palekana a ʻaʻohe pōʻino i ke kanaka. I ka wā e hoʻohana ai, ʻaʻole e hana nā kīʻaha wai PLA i nā mea ʻino a i ʻole e hoʻohaumia i ke kaiapuni. No laila, ʻo nā hue wai PLA kahi koho palekana a pili i ke kaiapuni.
ʻO ka mea hope loa, ʻaʻohe mea pili i ke kīʻaha wai plastik āu e koho ai, manaʻo mākou e hahai i nā loina hoʻohana a mālama ʻia:
1. Mai hōʻike i nā ʻōmole wai plastik i nā wahi wela kiʻekiʻe e pale i ka palaho a me ka hoʻoheheʻe ʻana o nā mea plastik.
2. E hoʻomaʻemaʻe mau i nā ʻōmole wai plastik e pale i ke koena o ka lepo a me ka ulu ʻana o ka maʻi bacteria.
3. E hō'ole i ka ho'ohana 'ana i nā mea ho'oma'ema'e ko'iko'i i mea e pale aku ai i ka palekana o nā mea plastic.
4. Inā ʻeha a ʻelemakule paha ke kīʻaha wai, pono e hoʻololi ʻia i ka manawa e pale aku ai i ka hoʻohana ʻana i nā kīʻaha e pōʻino ai ke olakino.
I ka hōʻuluʻulu ʻana, ʻo ka polyethylene a me ka polypropylene nā mea maʻamau maʻamau o ka ʻōmole wai plastik, aʻo ka polyvinyl chloride a me ka polystyrene e pale ʻia e like me ka hiki. Eia kekahi, ʻo ka PLA plastic biodegradable kahi koho palekana a pili i ke kaiapuni. Ke koho ʻana i kahi kīʻaha wai plastik, e ʻoluʻolu e hoʻolohe i ka palekana o ka mea a hahai i nā loina hoʻohana a mālama pono. Ma kēia ala, hiki iā ʻoe ke koho i kahi hue wai plastik palekana a hilinaʻi a hauʻoli i ke ola olakino.
