In this year, pollution control has become a hot spot again. The report calls for the continuous promotion of pollution prevention and control, and consolidation and expansion of the achievements of the Blue Sky Defense War. It is required that this year’s emissions of sulphur dioxide and nitrogen oxides should be reduced by 3%. Continuous efforts should be made to tackle air pollution in Beijing, Tianjin, Hebei and its surrounding areas, the Yangtze River Delta and the Fenwei Plain, and to strengthen the control of industrial, coal-fired and motor vehicle pollution sources. To strengthen the prevention and control of water and soil pollution, this year’s chemical oxygen demand and ammonia nitrogen emissions will decrease by 2%.

Since the pilot project in Hebei Province at the end of 2015, the environmental storm has lasted for more than three years, with great efforts and wide scope. In 2017, it has achieved full coverage of 31 provinces in the country; in 2018, more than 200 inspection teams were dispatched to carry out pull-net inspection, especially for the “scattered and dirty” enterprises that are not in place, the obsolete coal-fired boilers, the illegal production of non-pollution treatment facilities, excessive emissions and other issues found together and handed over publicly. In 2019, Li Ganjie, Minister of Ecological Environment, said that it would take four years for China to complete the second round of central ecological environment protection supervision and “look back”.
With the increasing pressure of environmental protection, the impact on compound fertilizer is also growing. As we all know, the pollution of compound fertilizer is mainly wastewater, dust, air pollution, and so on. Some enterprises that use phosphate ore as raw material also have the problem of stacking and disposal of phosphogypsum. The dechlorination process also involves hydrochloric acid. Beginning in 2016, with the increasing frequency of environmental protection inspection, the phenomenon of production restriction and parking of compound fertilizer plants has increased. For those devices that fail to meet the standards, they are required to rectify and upgrade environmental protection equipment. For those devices that are polluted heavily, they are required to relocate and enter industrial parks on the edges of Taihu Lake and Yangtze River Basin. According to incomplete statistics, in 2018, the capacity of the main enterprises with abnormal production and parking for more than three months has exceeded 3 million tons.
Compound fertilizer has a large production capacity, but its effective utilization rate is low. With the advancement of environmental protection, it is conducive to quickening the withdrawal of backward production capacity, accelerating the process of industry shuffling, and thus promoting the healthy development of the compound fertilizer industry.
