At present, China's coking enterprises are in general operating difficulties and face losses in the entire industry. The domestic price of coke dropped to 950 yuan per ton, and the average export price dropped to 130 US dollars per ton, with a decline of 50%. The overcapacity resulted in a backlog of products, while raw coal prices were increasing. Coke has become one of the few surplus industries announced by the National Development and Reform Commission. At the 2005 coke market symposium held recently, participating experts called for strengthening the macro-control of the coking industry, accelerating the process of rectification, eliminating backward production capacity, and promoting industrial restructuring and industrial upgrading. Since 2002, the rapid development of China's macroeconomic and steel industry has triggered an upsurge of investment in coking society. At that time, China had not yet implemented the coking industry access system. Many small coke ovens that did not meet the national industrial development policies had gone all the way, resulting in a rapid expansion of domestic coke production capacity. According to authoritative statistics, in 2002, the annual production capacity of various types of machine coke in China was 108 million tons, and by the end of 2005, it was about 320 million tons, which has increased twofold in three years. In addition, there is an annual capacity of 100 million to 150 million tons of projects under construction. These capacities far exceed the market demand of 270 million tons per year. The current total coking capacity in China is distributed in more than 1300 coking enterprises, with an average of less than 200,000 tons per company. At the same time, there are tens of millions of tons of soil coke. They are not only unburned but also have low resource utilization and serious pollution. They do not conform to the national coking industrial policy. (Yao Wen)
