• Resumen

  • Stricter pollution controls Due to increasingly strict government environmental standards and more frequent inspections, over the last two years Chinese magnesia companies have (either voluntarily or been forced to) upgraded their production facilities to reduce pollution. According to the Anshan Bureau of Environmental Protection, based in Liaoning's Anshan city, Haicheng is home to a total of 95 magnesia companies with 1,700 magnesia kilns. [...]recycling is being heavily promoted, through the proliferation of technologies capable of producing new magnesia materials out of spent magnesia bricks. China's crude steel output increased by 1.2% y-o-y in 2016 to 808.4m tonnes and a recovery in steel prices also saw some mothballed steel mills restart operations. International observers have cast doubt on the veracity of these claims, but the Chinese government has insisted it is ahead of schedule and that it wants to axe a further 100-120m tonnes by 2020, indicating that the trend in domestic refractories demand for the remainder of the decade will be negative. Many are concerned that the rise in Chinese steel demand and prices last year were led by government stimulus in areas such as infrastructure ( see box ), but this state funding for large raw materials-consuming projects is due to end sometime in the second half of this year.
