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, eia ka nui aʻe o ka poʻe kūʻai aku i ka nīnau o nā pahi kahiki 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 pahi pahi plastik, ua hana ʻia ia me nā ʻāpana plastik.

 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.
