Q: No ke aha e koho ai iā Shandong Yino?
A: 1. Hoʻolako paʻa a me ka maikaʻi
ʻO nā mea maka o 2-methyltetrahydrofuran, furfural a me 2-methylfuran, ʻo kā mākou huahana kālepa. Hoʻopaʻa mākou i kahi lako paʻa (ka puka makahiki o 15,000 tons, ka mea hana 2-methyltetrahydrofuran nui loa o ka honua); ʻO ka hana pono'ī o nā mea maka e hiki ai iā mākou ke hoʻomalu maikaʻi i ka paʻa o ka maikaʻi.
2. He kūʻokoʻa ka ʻoihana hoʻomalu maikaʻi i ka hale hana a mālama pono i ka maikaʻi
3. Ua uhi ka ʻoihana i ka honua, aia nā ʻelele ma nā awa a puni ka honua, a ua ʻae ʻia nā ʻōlelo kālepa like ʻole.
4. E nānā i ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau
Aia kekahi pūʻulu piha o ke kinoea ʻōpala, ka wai ʻōpala, a me ka mālama ʻana i ke koena o ka ʻōpala, a me ka hana hou ʻana iā lākou e hana i ka uila.
