ʻO nā hoʻololi ʻē aʻe i nā mea hoʻopili plastik

1. ʻO ka hoʻololi ʻana o ka ʻoihana paʻi kiʻi
Ke hoʻohuli nei i ka mōʻaukala o nā ʻeke plastik, e ʻike mākou he mōʻaukala ʻoi aku ka ʻoi aku ma mua o 100 mau makahiki.I kēia manawa i ka 21st century, hoʻomau ka ʻepekema a me ka ʻenehana, nā mea hou a me nā ʻenehana hou e hoʻomau nei, polyethylene, pepa, alumini alumini, nā plastics like ʻole, nā mea hoʻohui a me nā mea hoʻopili ʻē aʻe e hoʻohana nui ʻia, aseptic packaging, shockproof packaging, anti- static packaging, anti-child Packaging, hui puʻupuʻu, composite packaging, lāʻau lapaʻau a me nā ʻenehana ʻē aʻe e ulu aʻe a ʻoi aku ka makua, a ua puka mai nā ʻano pahu hou a me nā mea e like me nā ʻeke kū i ka plastic, i hoʻoikaika i nā hana o ka paʻi ʻana i loko. he nui na ala.

2. Nā pilikia palekana o nā mea plastik
I ka wā ma mua, loaʻa i nā ʻeke ʻeke plastik nā plasticizers a me ka bisphenol A (BPA), he mea pōʻino i ke olakino o ke kanaka, a ua paʻi pinepine ia mau lono.No laila, "ʻona a maikaʻi ʻole" ka manaʻo stereotype o ka poʻe i ka paʻi plastik.Eia kekahi, hoʻohana kekahi mau mea kālepa ponoʻole i nā mea i kūponoʻole i nā koi i mea e hōʻemi ai i nā kumukūʻai, e hoʻoikaika ana i ke kiʻi maikaʻiʻole o nā mea plastic.Ma muli o kēia mau hopena maikaʻi ʻole, loaʻa i ka poʻe ke kūʻē i ka pale plastik, akā ʻo ka mea ʻoiaʻiʻo, ʻo ka plastics i hoʻohana ʻia no ka ʻai ʻana i ka meaʻai he hoʻonohonoho piha o EU a me nā lula aupuni, a ʻo nā mea maka i hoʻohana ʻia e nā ʻoihana pono e hoʻokō i nā koi o kēia mau lula. , me ka loaʻa ʻana o nā lula EU koʻikoʻi a me nā kānāwai REACH kikoʻī loa e pili ana i nā mea plastik e pili ana i ka meaʻai.
Ua hōʻike ka British Plastics Federation BPF i kēia manawa ʻaʻole palekana wale nō, akā hāʻawi pū kekahi i ke kōkua nui i ke olakino lehulehu a me ka holomua o ke kaiāulu kanaka.

3. Lilo nā biopolymers degradable i koho hou no nā mea hoʻopili
ʻO ka puka ʻana mai o nā mea biodegradable e hana i nā mea hoʻopili i kahi koho hou.Ua ho'āʻo pinepine ʻia a hōʻoia ʻia ka paʻa o ka meaʻai, ka palekana a me ka maikaʻi o ka hoʻopili ʻana i nā mea biopolymer, kahi i hōʻoia piha ʻia ʻo nā ʻeke ʻeke biodegradable ka meaʻai kūpono loa i ka honua.
I kēia manawa, hiki ke hoʻokaʻawale ʻia nā polymers biodegradable i ʻelua mau ʻāpana: kūlohelohe a me ka synthetic.ʻO nā polymers degradable kūlohelohe ka starch, cellulose, polysaccharides, chitin, chitosan a me kā lākou derivatives, etc.;Ua māhele ʻia nā polymers degradable synthetic i ʻelua ʻano: synthesis artificial a me bacterial.ʻO nā polymers degradable i hoʻohui ʻia e ka bacteria me nā poly Hydroxyalkyl alcohol esters (PHAs), poly(malate), synthetic degradable polymers me nā polyhydroxyesters, polycaprolactone (PCL), polycyanoacrylate (PACA), etc.
I kēia mau lā, me ka hoʻomau mau ʻana o ke ola waiwai, ʻoi aku ka nui o ka nānā ʻana o ka poʻe i ka hoʻopili ʻana o nā huahana, a ʻo ka palekana a me ka palekana o ke kaiapuni i lilo i mau pahuhopu.No laila, pehea ka hoʻomaka ʻana i ka pōʻai ʻōmaʻomaʻo e pili ana i ke kaiapuni a me ka pollution-free ʻōmaʻomaʻo ua lilo i kumuhana hou i hoʻomaka ai nā ʻoihana paʻi ma koʻu ʻāina e nānā.
