E kāhāhā ana ʻoe no ka hoʻohana nui ʻia ʻana o nā ʻeke ʻōpala a puni ka honua a ʻaʻole ia he mea hou.ʻO nā ʻeke plastik ʻōmaʻomaʻo āu e ʻike ai i kēlā me kēia lā i hana ʻia me ka polyethylene.Ua hana ʻia lākou ma 1950 e Harry Washrik a me kāna hoa, ʻo Larry Hansen.No Kanada mai nā mea ʻelua.
He aha ka mea ma mua o ka ʻeke ʻōpala?
Ma mua o ka māhele ʻia ʻana o nā ʻeke ʻōpala, nui ka poʻe i kanu i ka ʻōpala ma ka pā.Puhi ʻōpala kekahi poʻe.Ma hope koke iho, ua ʻike lākou he mea pōʻino maoli ke puhi ʻana a me ke kanu ʻana i ke kaiapuni.Hiki i nā ʻeke ʻōpala ke kōkua i ka poʻe e hana maikaʻi i ka ʻōpala.
ʻEke ʻōpala mua
I ka wā mua, ua hoʻohana ʻia nā ʻeke ʻōpala no nā hana ʻoihana.Ua hoʻohana mua ʻia lākou ma ka haukapila Winnipeg.Ua hana ʻo Hansen no ka carbide union, nāna i kūʻai i ka mea hou mai iā lākou.Ua hana ka hui i nā ʻeke ʻōpala ʻōmaʻomaʻo mua i ka makahiki 1960 a kapa ʻia lākou he ʻeke ʻōpala hale.
Ua hoʻomaka koke ka mea i manaʻo ʻia a hoʻohana ʻia i nā ʻoihana a me nā ʻohana.I ka hopena, ua lilo ia i huahana kaulana.
ʻeke huki
I ka makahiki 1984, ua komo ka mōʻaukala o nā ʻeke ʻōpala i ka mākeke, e maʻalahi ai ka poʻe e lawe i nā ʻeke piha.Ua hana ʻia ke kaula huki mua me ka plastic density kiʻekiʻe.He lōʻihi kēia mau ʻeke a loaʻa iā ia kahi mīkini pani ikaika.Akā ʻoi aku ka pipiʻi o kēia mau ʻeke.Kaulana ʻia nā ʻeke huki huki ma ka home a maʻalahi hoʻi e lawe, no laila ua kūʻai au iā lākou no ka uku keu.
He mea hoʻopaʻapaʻa ke aloha kaiapuni o nā ʻeke ʻōpala polyethylene.I ka makahiki 1971, ua hoʻolālā ʻo Dr. James Gillett i kahi plastik e wāwahi i ka lā.Ma o ka mea i hana ʻia, hiki iā mākou ke hoʻohana i nā ʻeke plastik a kū mau ma ka ʻaoʻao o ka pale kaiapuni.Loaʻa nā ʻeke biodegradable ma ka mākeke i kēia mau lā a hoʻohana ʻia e nā poʻe he nui.
