Out behind the product is key for energy saving and pollution remediation

In China's "Eleventh Five-Year" plans, the unit GDP energy consumption by 20%, the total discharge of major pollutants by 10% as a binding target, highlights the transformation of economic growth mode of thinking. According to the plan, each unit of GDP energy consumption by about 4%, however, as the "Eleventh Five-Year" in 2006 the first year, reducing energy consumption did not achieve the target, which means the next few years the government will further increase the intensity of energy Great.

Cement as a high resource consumption, high energy consumption and high pollution and excess capacity in the industry has become a focus of government regulation of industries. As the backward production capacity more than 50% in 2005, China's average consumption of standard coal per ton of cement 170 kg, 36% higher than international standards. Comparison of energy consumption from the industrial value added terms, China is also at a high level in 2000 6664 tons of standard coal / millions of dollars, even taking into account the price of cement in China is only 1/3-1/4 of this factor in developed countries, China's cement unit energy intensity of industrial value added is still 4-5 times higher than the advanced international level.

The most advanced dry process cement kiln energy-saving effect is obvious, the unit energy consumption of about 135 kg of standard coal / ton, energy intensity of industrial value added was 5.2 thousand tons of coal equivalent / million, than the industry average by 20% or more.

Emissions of pollutants from the atmosphere of view, new dry process kiln near the international level, while behind the kiln pollution is serious, leading to the average domestic cement industry emission levels much higher than international standards.

In addition, the backward cement production capacity of the waste of resources is also very alarming. To limestone, for example, a lot of behind the cement kiln with artificial mechanical and artisan mining nearly 80% of the limestone mine, with an average output rate of only 50%, while the number of large new dry kiln companies have their own dedicated limestone mine, a highly mechanized, computerized planning of mining and reclamation operations, production and comprehensive utilization rate of more than 90%.

Can be seen from the above analysis, the domestic cement industry, high energy consumption, heavy pollution mainly by the high percentage of backward production capacity caused by the production if it were all part of NSP replaced, then the industry average power consumption will drop by 20%.
Eight countries in April last year, ministries appear "about speeding up restructuring of cement industry in a number of opinions" and the October 17 NDRC promulgated the "Development of Cement Industry Policy" and "cement industry development plan" to eliminate backward production capacity on have given a high priority.

According to the structural adjustment program, by 2010 the proportion of new dry cement to 70%, total elimination of backward production capacity of 250 million tons, cement unit comprehensive energy consumption decreased by 25%, significantly reduce dust emissions, industrial waste (including powder coal ash, blast furnace slag, etc.) over Facilitation amount of 250,000,000 tons, limestone resource utilization from 60% to 80%.

National Development and Reform Commission on February 18 this year to Express documents issued in the form of "backward cement production capacity on the good work-out notice," clearly made the provinces, autonomous regions and municipalities and eliminate backward cement production capacity in the number of requests for the development of practicable, eliminate backward production capacity to implement the work program, and with the provinces, autonomous regions and municipalities in the timing of this year was signed in Beijing "during" phase out backward cement production capacity of letters of responsibility. Development and Reform Commission also said it will in due course with the authorities closed down backward on the cement around the elimination of backward cement production capacity and the work of inspectors, and inspectors report results to the State Department.

The NDRC issued during the Spring Festival Express documents demonstrated the central government to eliminate backward production capacity of cement degree of attention and urgency of this work. As we reported in previous research in related companies, as repeatedly emphasized, the backward cement production capacity out to follow the economic growth mode transformation of the necessary steps to implement will be much higher than in the past, used to eliminate backward production capacity slow, excessively bureaucratic situation will occur fundamental changes.
