China: China's Ministry of Industry and Information Technology (MIIT) has unveiled a document to ask cement companies in north China to carry out peak-shifting production on a trial basis in the winter. The peak-shifting production will not only ease the 'haze weather,' but also enhance the cement market and reduce producers' costs, according to industry insiders.

Due to fierce market competition, cement enterprises in north China produce cement at full capacity in the winter to seize the opportunity when the energy supplies end and building operations start. However, in the summer, many enterprises are forced to produce at half of their installed capacity due to the glut of cement on the market. As the cement industry is a high energy-consumption industry, the overlap of cement production and energy supply in winter increases coal consumption and leads to haze weather in north China. If peak production were carried out in winter for four months, about 4.36Mt of coal and 177bnm3 of flue gas emissions would be cut in the whole northern area, which could help improve the local environment. The peak-shifting production could also help ease overcapacity.

After the peak-shifting, cement enterprises in north and northeast China will suspend production for four to five months in winter and the overcapacity rate in the domestic cement industry will fall to 16 – 21% from the current 51%, which would help enhance the industrial climate.
