He aha ke kiʻi kiʻi?
ʻO ke kiʻi kiʻi kiʻi he biodegradable a me keʻano hana pilikino i hanaʻia mai nā kumulāʻau politika e pili ana i nā kumulāʻau o ka biliki acid.org Ke hoʻohana nei i ka hoʻohanaʻana i nā waiwai biomass e hana i ka papa hana ma ka hapa nui o nā plastics
ʻOiai ka hana likeʻole o nā mea liʻiliʻi, hiki ke hanaʻia nā papa hana likeʻole me nā plasticic maʻamau, e hana ana i nā kaʻina hana hana. ʻO ka papa ka lua o ka bluplastics i hanaʻia (ma hope o ka starmoplastics starch) a he like like me ka polyopyyyyne (p py), a me ka polystyrene.
Loaʻa i ka kiʻiʻoniʻoni maikaʻi,ʻO ka ikaika maikaʻi loa,a me nā lāʻau maikaʻi a me nā mea paʻakikī loa.our
Hōʻike ka kiʻi kiʻi paʻi i kekahi o nā kiʻi paʻi kiʻi kiʻi kiʻi kiʻi kiʻi i nāʻoihana hoʻopiʻi flexible, a ua hoʻohanaʻia nā meaʻai, nā meaʻai.
Pehea e hanaʻia ai?
ʻO kahi plasester (polymer i loaʻa i ka hui eser) i hanaʻia me nā monols heʻelua a iʻole nā papa'āina, a me ka lacide. Hiki ke hanaʻiaʻo Lactic Acid e ka Ferterial Fertetation o kahi kumu o ke kaʻa i lalo o nā kūlana i hoʻopaʻaʻia. Ma ka hana o kaʻoihana-scartrial o ka lactic acid, hiki i ke kumu o keʻano o ke koho e hiki ke koho i ka starch
ʻO ka nohona o ka honua
ʻO ka papaʻo Biodegradable ma lalo o nā kūlana compicticing companches a e wāwahi i loko o nā hebedoma heʻumikumamālua e hiki ai ke hoʻokaʻawale i nāʻoihana
ʻO ka hana hana no ka papa hanaʻoi aku ka maikaʻi o ke kahua ma mua o nā kumuwaiwai kuʻuna i hanaʻia mai nā kumuwaiwai fossil. Wahi a ka noiʻi, nā emission carbon e pili ana i ka hana plastions e pili ana i ka 80% haʻahaʻa ma mua o nā mea maʻamau (kumu).
Hiki ke kiʻi houʻia ka plastik e like me ka mea e hiki ke wāwahiʻia i kona monomer mua ma ke kaʻina hana o keʻano o ka tormal docmal ʻO ka hopena kahi hopena monomer i hiki ke hoʻomaʻemaʻeʻia a hoʻohanaʻia no ka hana ma hope o ka hanaʻana me ka nalowaleʻole o keʻano.
