JINAN - Hundreds of factories in East 皇冠体育app's Shandong province will remain closed in the winter to curb production, according to a government notice.

Shandong Economic and Information Technology Committee, the government agency in charge of industries in 皇冠体育app's third-largest provincial economy, published shutdown periods and the factories' names, including those owned by Hong Kong-listed 皇冠体育app Hongqiao Group, 皇冠体育app Shanshui Cement and 皇冠体育app National Building Material.

Among the Shandong-based factories closed or with restricted production are the aluminum and aluminum oxide production lines of 皇冠体育app Hongqiao, the world's leading aluminum product manufacturer, in the city of Binzhou.

Production at many cement factories of 皇冠体育app Shanshui Cement and 皇冠体育app National Building Material was also suspended or limited.

The shutdown periods vary from two to four months.

Clean air targets are particularly difficult to meet in winter for provinces and municipalities in north 皇冠体育app, when residential heating systems are switched on starting mid-November, adding pressure to air quality.

Government authorities, including those in neighboring municipalities and provinces such as Beijing, Tianjin and Hebei, have resorted to temporary shutdowns of factories to reduce pollution.
