Mea hana ʻoihana o nā mīkini thermoforming.
I Malaki 2022, ua hoʻomau ʻia ka ʻElima UN Environment Conference i ka "Plastic Pollution Resolution (Draft)" ma Nairobi, ke kapikala o Kenya. Ma ka hālāwai, ua kau inoa ke poʻo o ka moku'āina, Kuhina Kaiapuni a me nā ʻelele ʻē aʻe mai 175 mau ʻāina i kēia mōʻaukala. Manaʻo ka ʻōlelo hoʻoholo e hāpai i ka hoʻokele honua e hōʻemi i ka pollution plastic a me ka manaʻolana e hoʻopau i ka pollution plastic ma 2024.
Ka nānā ʻana i nā mea hiki ke hoʻopau ʻia
Wahi a ka hōʻike kūlohelohe mua i hoʻokuʻu ʻia e ka OECD (Organization for Economic Co-operation and Development), i ka makahiki 2019, ʻo ka hoʻopuka makahiki o nā huahana plastik honua e pili ana i 460 miliona mau tons, a ua hōʻea ka ʻōpala plastik makahiki i 353 miliona tons. ʻO nā huahana i hana ʻia, e komo pū ana i ka ʻeke plastik (40%), nā huahana mea kūʻai aku (12), textiles (11%), etc.
Me ka hoʻomohala ʻana i nā kulekele, e hoʻonui mau ʻia nā mea biodegradable.
ʻO ka hoʻokūkū no ka hiki ke hana
I kēia manawa, hiki ke hoʻokaʻawale ʻia ka plastic degradable ma ka mākeke i ʻelua ʻano: "petroleum base" a me "biological base". Hoʻokaʻawale ʻia ka ʻokoʻa ma waena o nā mea ʻelua i ka hana ʻana i nā mea maka. Hoʻokumu ʻia ka plastic degradable e pili ana i ka Petroleum ma muli o ka ikehu fossil, ʻo ka hapa nui o ka PBS (polynoxylxylxylxyl glycol), PBAT (alcoholic glycolic glycolin a me phenyl -dysteenol (polymer maʻamau), PCL (polycopide), etc.; ma ka kulina, ka mauʻu a me nā mea olaola ʻē aʻe, e like me ka PLA (polylactic acid) a me ka PHA (polyxide alkyl).
Ma waena o nā mea biodegradable i ʻōlelo ʻia ma luna, i hoʻohālikelike ʻia me nā mea hiki ke hoʻohaʻahaʻa ʻia e ke kino, ʻoi aku ka haʻahaʻa o ka PLA (polyal acid) a me nā kumukūʻai PBAT, a ʻoi aku ka oʻo o ke kaʻina hana. ʻO ke koho nui o nā plastic maʻamau.
ʻO nā mea maka o PLA ka nui o ka palaoa a me ka mauʻu. Ma hope o ka hoʻohana ʻana, hiki ke hoʻoheheʻe koke ʻia i carbon dioxide, ka wai a me nā paʻakai inorganic ma lalo o nā kūlana compost (industrial compost). (PLA) hana i ka pōʻai kalapona.
Pono mākou e hoʻonui i ka ʻike no ka mālama ʻana i ke kaiapuni a hoʻemi i ka pollution plastic. ʻO kā mākoukūʻai nui i ka mīkini thermoforming hiki iā ia ke hana i ka papa ʻaina hoʻokahi manawa a PLA, ka hana maʻalahi a maʻalahi, ka papahana naʻauao, hiki ke hoʻokō i kāu mau pono hana.
