国际能源价格上涨使得美国天然碱生产成本和运输费用显著上升,近两年逐步减少对亚洲市场的出口,造成亚洲地区供应偏紧,价格上涨。2008年由于产量释放有限,亚洲地区供应仍将偏紧,而2009年由于中国、印度、东欧地区有超过300万吨产能释放,供应紧张局面将会得到缓和。 The rise in international energy prices has led to a significant increase in the production cost and transportation costs of trona in the United States. In the past two years, the export to the Asian market has been gradually reduced, resulting in tight supply and rising prices in Asia. Supply in Asia will remain tight due to limited output in 2008, while supply will be eased in 2009 as more than 3 million tons of capacity are released in China, India and Eastern Europe.
