Pehea i hana ʻia ai ka pahi pahi biodegradable?

E like me kā mākou ʻike a pau, ke ulu nui nei nā huahana biodegradable i ka mākeke i kēia manawa no ka mea he kū hoʻokahi ke kaiapuni no mākou a pono mākou e pale iā ia. akā ʻo ka ʻoiaʻiʻo, aia nō nā huahana i hoʻohana ʻia i ka plastik ʻo ia ka mākeke nui loa. No laila, ʻoi aku ka nui o nā mea kūʻai aku i ka nīnau no nā pahi ʻumi biodegradable mai iā mākou.

No ke kaʻina hana o ka hana ʻūlū biodegradable, ua like ia me ke kaʻina pahi pahi plastik akā me nā ʻano mea like ʻole. no ka pahiolo plastik , ua hana ia me na mea palaki .

 Ua kapa ʻia ʻo PLA biodegradable particles ʻo ia ka polylactic acid. ʻO ka polylactic acid (PLA) kahi mea biodegradable hou i hana ʻia mai ka starch maka kumu i manaʻo ʻia mai nā kumu mea kanu hou e like me ke kulina. ʻO ka starch maka mea i saccharified e kiʻi i ka glucose, a laila fermented e ka glucose a me kekahi mau strains e hana kiʻekiʻe-maʻemaʻe lactic acid, a laila synthesize polylactic waika me kekahi molecular kaumaha ma ka chemical synthesis. Loaʻa iā ia ka biodegradability maikaʻi a hiki ke hoʻohaʻahaʻa ʻia e nā microorganism i ke ʻano ma hope o ka hoʻohana ʻana, i ka hopena o ka hana ʻana i ka carbon dioxide a me ka wai me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni, he mea maikaʻi loa ia i ka pale ʻana i ke kaiapuni a ʻike ʻia ʻo ia he mea pili i ke kaiapuni.

E hoʻohana ʻia ka mea no ka injection no ka paʻa e like me ka mea maʻamau, loaʻa iā mākou nā ʻano hiʻohiʻona like ʻole o ke ʻano o ka lima, no laila e hoʻoheheʻe ʻia nā lima ma lalo o nā mīkini injection:

Pēlā nō me ke poʻo, e hana ʻia nā ʻāpana a pau o ke poʻo ma lalo o nā mīkini injection, me nā laina hui ʻakomi e hui pū ai nā poʻo. a i loko o ka hale hana hoʻopaʻa lole , e hōʻuluʻulu nā limahana i ke poʻo a me nā lima a hoʻopaʻa iā lākou i loko o ka pūʻolo.
