BiodegradableʻAʻole pono nā mea polymer i kahi kūlana kūikawā a i ʻole ke ʻano o nā kūlana o waho e like me ka māmā, ka wela a me ka wai i ka hana hoʻohaʻahaʻa.Pono lākou e hoʻohana walemicroorganismse hana i ka hopena physicochemical maikaʻi a hoʻohua hopekalapona kalapona.ʻO nā ʻano mea a pau i hana ʻia e ka hopena degradation, ʻaʻole ia e hoʻopōʻino a hoʻoweliweli iki i ke olakino kanaka.
ʻO nā ʻeke hoʻopili biodegradable -ʻeke kopea me nā ʻeke hōʻailona hiki ke hana hou ʻia -ʻeke ʻeke meaʻaihana ʻia e Yantai Meifeng Plastic Packaging Co.
ʻEkolu mau ʻano nui obiodegradablemea polimer.ʻO kekahi nā mea polymer i hana ʻia e nā microorganism, i loaʻa nui ʻia e ka microbial fermentation, a ʻo ka mea nui loa he polyhydroxybutyrate, nona nā waiwai biodegradation maikaʻi.Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ka hoʻoili ʻana a me ka hana ʻana o ia mau mea, a ʻaʻole i hoʻohana pinepine ʻia i ka hana kikoʻī.ʻO ka lua he mau mea polymer synthetic.I kēia manawa, ʻoi aku ka maʻamau o nā mea polymer synthetic i ka mākeke Kina he polyvinyl alcohol a me polycaprolactone.I waena o lākou, hoʻohana nui ʻia ka polycaprolactone i ka hoʻopili meaʻai.ʻO ke kolu he mau mea polymer maoli.ʻO nā mea polymer kūlohelohe maʻamau ka cellulose, starch, protein, a me chitosan ma ke ʻano he matrix.Ma hope o ka hoʻohana ʻana no kekahi manawa, hiki ke hoʻohaʻahaʻa maikaʻi ʻia nā mea polymer kūlohelohe a ʻaʻohe hopena i ke kaiaola o waho.kekahi haumia.
