In January 19th, the Ministry of Environmental Protection announced that China will implement the special emission limits of air pollutants in the Beijing Tianjin Hebei air pollution transmission channel city (that is, the "2+26" city). For thermal power, steel, petrochemical, chemical industry, nonferrous metals (excluding alumina), cement and other related industries, the existing enterprises as well as in the use of the boiler should be from the beginning of October 1, 2018, implementation of sulfur dioxide, nitrogen oxides, particulate matter and volatile organic compounds in particular emission limit; for coking chemical industry, the existing enterprises should begin to implement special emission limits from October 1, 2019; for the national emission standard has not stipulated the special emission limit of the industry, all shall emission in the revision of the standard or modified, the existing enterprises to implement. Since a 2017 began in April, about a year's "2+26" city environmental inspection and mid November carried out by the heating season, staggering production has not ended, and the Ministry of environmental protection for "2+26" city then the new tactics, particularly atmospheric pollutant emission limits, this will result in greater pressure on production. Due to environmental impact, EPS production and consumption of plastic raw materials have declined to varying degrees in recent years. Some small and medium-sized enterprises are forced to shut down or fail because they cannot afford heavy costs. All of the city of Tianjin and pollution of transmission, EPS downstream in the insulation board, in the environmental impact, the real estate regulation policy to suppress and XPS alternative products, the construction of new EPS insulation board amount declined significantly on, led to the current EPS of the insulation material market share accounted for around 40%. And it is reported that the environmental pressure, the Spring Festival approaching business orders for poor downstream enterprise more than at the end of January and early February bubble closed after the Lantern Festival to resume production, even delayed until 3 months late, compared with the previous year the Spring Festival holiday extended a lot. From the current trend, environmental protection will still be the norm in 2018. Air pollution control code, which is bound to continue to suppress the EPS downstream enterprises operating in the construction industry, the amount will continue to decline, affected by this, a UN expected in 2018 domestic consumption may still fell EPS.
