Hoʻokaʻawale ʻia ke kaulahao ʻoihana biodegradable plastics i ʻekolu mau ʻāpana: ka hoʻolālā a me nā kumu waiwai kī, nā huahana plastik biodegradable, a me ka hoʻohana ʻana i nā plastic biodegradable. Ma waena o lākou, ʻo PLA a me PBAT nā kuhikuhi hoʻomohala nui o nā mea degradable i ka wā e hiki mai ana. Hāʻawi ʻia nā ʻoihana ʻelele o ke kaulahao ʻoihana plastic degradable o Kina ma Shandong, Anhui, Guangdong, Jiangsu a me nā wahi ʻē aʻe, akā liʻiliʻi ka nui o nā ʻoihana, a pono e hoʻomaikaʻi ʻia ka mākeke.

ʻO ka ʻike nui o ke kaulahao ʻoihana o nā plastic degradable: ʻO PLA a me PBAT ke alakaʻi hoʻomohala nui o nā mea hiki ke hoʻohaʻahaʻa i ka wā e hiki mai ana. 

ʻO ka upstream o ke kaulahao ʻoihana o nā plastic degradable ka hana ʻana i nā mea maka. Wahi a ke kumu o nā mea maka, ua hoʻokaʻawale ʻia nā mea maka i loko o nā plastik bio-based a me nā plastics-based petroleum. Ma waena o lākou, ʻo nā kumu kumu o nā plastics bio-based (e like me ka starch based plastics, PLA, PHA, a me nā mea ʻē aʻe) he mau kumuwaiwai kūlohelohe kūlohelohe e like me ka starch (e like me ke kulina, ka ʻuala, a me nā mea ʻē aʻe), ka mauʻu mea kanu, chitin, a pela aku, oiai ua hookumuia na plastic i hoohanaia i ka aila (e like me PBAT, PCL, PBS, PGA, etc.) mai na huahana petrochemical e like me ka monomer. ʻO ke kahawai waena o ke kaulahao ʻoihana palaki biodegradable ka hana ʻana i nā huahana plastik biodegradable, e komo pū ana me ka papa ʻaina disposable, nā ʻeke plastic disposable, pepa ʻōwili, lole, kiʻi ʻoniʻoni, nā mea paʻi 3D, nā mea lapaʻau, a me nā mea ʻē aʻe. ka hoʻohana ʻana i nā plastic degradable, me ka hoʻopili ʻana, nā mea uila, nā kaʻa a me ka lawe ʻana, nā mea kūʻai aku, nā lole lole, ka mahiʻai, nā uhi, ka paʻi 3D, ka lāʻau lapaʻau hou, ka hale hana a me ke kūkulu ʻana, etc. Ua hoʻokumu a hoʻokomo nā ʻāina a me nā ʻāina i nā kānāwai a me nā lula e pili ana i ka hoʻohana ʻana i nā plastic non-degradable ma o ka pāpā ʻana, ka palena, ka ʻohi koi a me ka ʻauhau haumia, a me ka hoʻomohala ikaika ʻana i nā mea biodegradable hou e pale ai i ke kaiapuni a me ka lepo. Mai 2019 a 2020, ua hoʻopuka pū nā ʻāina he nui ma Asia i nā kulekele hoʻopaʻa ʻana i ka plastic, me China, Pakistan, India, Philippines, Thailand, Algeria a me nā ʻāina ʻē aʻe. I ka wā e hiki mai ana, e ulu wikiwiki ka noi no nā plastic biodegradable ma Asia. ʻO PLA a me PBAT nā kuhikuhi hoʻomohala koʻikoʻi o nā mea degradable i ka wā e hiki mai ana. ʻO PLA kekahi o nā plastic degradable maʻamau. ʻO ke kaʻina hana he pollution-free, a hiki ke hoʻohaʻahaʻa ʻia ka huahana i carbon dioxide a me ka wai me ka hopena ʻole i ke kaiapuni. Loaʻa iā PLA ka biosafety hilinaʻi, biodegradability, nā waiwai mechanical maikaʻi a me ka hana maʻalahi, a hoʻohana nui ʻia i ka ʻeke, ʻoihana textile, mulch mahiʻai a me nā ʻoihana polymer biomedical. ʻO ka PBAT kahi plastic degradable thermoplastic me ka ductility maikaʻi a me ka elongation i ka wā hoʻomaha, a me ka pale wela maikaʻi a me ka hana hopena. Ma muli o kāna hana kiʻiʻoniʻoni maikaʻi a me ka maʻalahi o ka puhi ʻana i ke kiʻiʻoniʻoni, hoʻohana nui ʻia ʻo PBAT ma ke kahua o ka kiʻiʻoniʻoni hoʻokuʻu ʻia a me ke kiʻi mahiʻai. He haʻahaʻa ko PBAT no nā mea waiwai i hoʻopaʻa ʻia i ka ʻaila, ʻoi aku ka ʻenehana oʻo a me ka liʻiliʻi o ka hoʻopukapuka kālā. Hoʻohui ʻia me ke ʻano, kahua noi a me ke kumukūʻai hana o PBAT, manaʻo ʻia e lilo i ʻāpana nui loa o nā plastic degradable i ka wā e hiki mai ana.
