I ka hapa mua o 2022, ʻaʻole i hoʻomau ka mākeke calcium carbide kūloko i ka nui o ka fluctuation ma 2021. Ua kokoke ka mākeke holoʻokoʻa i ka laina kumu kūʻai, a ua kau ʻia i ka fluctuations a me nā hoʻololi ʻana ma muli o ka hopena o nā mea maka, ka lako a me ke koi. , a me nā kūlana lalo. I ka hapa mua o ka makahiki, ʻaʻohe hiki ke hoʻonui hou ʻia o nā mea kanu PVC carbide kūloko, a ua kaupalena ʻia ka piʻi ʻana o ka mākeke calcium carbide. He mea paʻakikī i nā ʻoihana chlor-alkali e kūʻai i ka calcium carbide e mālama i kahi ukana paʻa no ka manawa lōʻihi.
