No ke aha e hoʻohana ai i nā plastic biodegradable?
ʻO ka plastik kahi mea kumu nui. Me ka ulu wikiwiki o ka hoʻokele waiwai a me ke kaiāulu a me ka puka ʻana mai o ka nui o nā ʻoihana hou e like me ka e-commerce, express delivery and takeout, ke piʻi wikiwiki nei ka hoʻohana ʻana i nā huahana plastik.
ʻAʻole lawe wale ka plastic i ka ʻoluʻolu i ke ola o ka poʻe, akā ke kumu hoʻi i ka "pollution keʻokeʻo", kahi e hōʻino nui ai i ke kaiaola a me ke olakino kanaka.
Ua hōʻike maopopo ʻo Kina i ka pahuhopu o ke kūkulu ʻana i kahi Kina nani, a ʻo ka mālama ʻana i ka "pollution keʻokeʻo" ka mea e pono ai ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kaiaola a kūkulu i kahi Kina nani.
He aha ke ʻano o nā plastic biodegradable?
ʻO nā plastics degradable he plastics i hoʻohaʻahaʻa ʻia e ka hana a nā microorganism i ke ʻano, e like me ka lepo, ka lepo one, ka wai hou, ka wai kai a me nā kūlana kūikawā e like me ka composting a i ʻole anaerobic digestion, a hope loa i hoʻohaʻahaʻa ʻia i carbon dioxide (CO2) a i ʻole / / a me methane (CH4), wai (H2O) a me nā paʻakai anorganic mineralized o ko lākou mau mea, a me ka biomass hou (e like me nā microorganism make, etc.).
He aha nā ʻāpana o nā plastic degradable?
Wahi a ka Standard Guide for Classification and labeling of degradable plastic products organised by China Federation of Light Industry, degradable plastics loaʻa nā ʻano hoʻohaʻahaʻa like ʻole i ka lepo, compost, moana, wai hou (nā muliwai, nā muliwai, nā loko) a me nā wahi ʻē aʻe.
Wahi a nā kūlana kaiapuni like ʻole, hiki ke hoʻokaʻawale ʻia nā plastic degradable i:
ʻO nā plastik hiki ke hoʻoheheʻe ʻia ka lepo, nā plastic degradable composting, nā plastik hoʻoheheʻe ʻia i ka wai maʻemaʻe, nā plastics degradable digestion anaerobic sludge, nā plastics degradable digestion anaerobic paʻa kiʻekiʻe.
He aha ka ʻokoʻa ma waena o nā plastic degradable a me nā plastics maʻamau (non-degradable)?
Hana ʻia nā plastic kuʻuna me ka polystyrene, polypropylene, polyvinyl chloride a me nā mea hoʻohui polymer ʻē aʻe me nā paona molekala o nā haneli haneli a me ke ʻano kemika paʻa, he paʻakikī ke hoʻohaʻahaʻa ʻia e nā microorganism.
He 200 mau makahiki a me 400 makahiki no ka hoʻohaʻahaʻa ʻana i nā plastic plastic kuʻuna i loko o ke kaiapuni kūlohelohe, no laila e maʻalahi ka hoʻohaumia ʻana i ke kaiapuni ma ke kiola ʻana i nā plastic plastic kuʻuna i ka makemake.
He ʻokoʻa loa nā plastic biodegradable me nā plastic plastic kuʻuna ma ke ʻano kemika. ʻO kā lākou mau kaulahao polymer nui ka nui o nā mea paʻa ester, hiki ke hoʻopaʻa ʻia a hoʻohana ʻia e nā microorganisms, a hoʻopau hope ʻia i loko o nā molekala liʻiliʻi, ʻaʻole ia e hoʻohaumia mau loa i ke kaiapuni.
ʻO nā ʻeke plastik maikaʻi maʻamau maʻamau ma ka mākeke hiki ke hoʻoheheʻe ʻia?
E like me nā koi o ka lepili o GB/T 38082-2019 "Biodegradable plastic Shopping peke", e like me ka hoʻohana like ʻole ʻana o nā ʻeke kūʻai, pono e hōʻailona maopopo ʻia nā ʻeke kūʻai "nā ʻeke kūʻai kūʻai pololei ʻai" a i ʻole "pili pololei ʻole i ka meaʻai. nā ʻeke kūʻai plastik biodegradable”. ʻAʻohe hōʻailona "ʻeke plastik pili i ke kaiapuni".
ʻO nā ʻeke plastik pale kaiapuni ma ka mākeke ʻoi aku ka nui o nā gimmicks i hana ʻia e nā ʻoihana ma ka inoa o ka mālama kaiapuni. E ʻoluʻolu e wehe i kou mau maka a koho pono.
