According to Sinochem New Network, the Ministry of Ecology and Environment recently issued the \"Pollution Control Standards for Coal Chemical Gasification Slag (Draft for Comment)\\" (hereinafter referred to as the \"Standards\") to seek public feedback. The “Standards” set specific requirements for the disposal and utilization of gasification slag, filling the gap in **environmental and ecological standards** in this field. It is understood that gasification slag contains toxic and harmful substances such as heavy metals and benzo[a]pyrene, and the leachates from some of this slag are acidic or alkaline. Improper collection, storage, transportation, backfilling, filling, utilization, and disposal can pose pollution risks. At present, the recycling rate of gasification slag is very low, with landfilling and dumping being the main methods. The large amounts of gasification slag that are stored and landfilled hinder the sustainable development of coal gasification technology. It is urgent to find ways to dispose of this slag on a large scale, while keeping environmental risks under control, in order to promote the green and healthy development of coal gasification technology. A relevant official from the Ministry of Ecology and Environment stated that the formulation of these \"Standards\" focuses on achieving a balance among environmental, economic, and social benefits, adhering to four principles: the first is the principle of controlling pollution at key stages in the production process. Research is conducted on the pollution emission points at key stages such as the generation, collection, storage, transportation, backfilling, filling, utilization, and landfilling of gasification slag, and corresponding pollution control measures and limits are proposed for each stage. Environmental risk assessments are focused on the processes of backfilling, filling, utilization, and landfilling of gasification slag, and pollutant limit requirements for the gasification slag and its treatment by-products are established to control environmental pollution during the large-scale disposal of gasification slag. The second is the principle of pollution prevention and control per unit. In view of the characteristics of high generation volume, high residual carbon content, and high moisture content of the gasification slag, it is proposed that generating units should reduce the amount of such slag by controlling gasification process parameters and implementing dehydration measures, thereby fulfilling their responsibilities for pollution control and curbing environmental pollution risks at the source. Third is the principle of economic and technical feasibility. By taking into account the economic, market, and industrial development conditions in the areas where gasification slag is generated, a technical and economic feasibility assessment is conducted to ensure that pollution control requirements are practical to implement and that the associated costs are competitive in the market, thereby promoting the sustainable development of coal chemical enterprises. Fourth is the principle of large-scale consumption. Focusing on large-scale disposal methods for gasification slag, it enables the effective management of both historically accumulated and newly generated gasification slag, provided that environmental risks remain under control. The Standards specify the overall requirements for pollution control of coal chemical gasification slag, and are applicable to pollution control and environmental management throughout the entire process of coal chemical gasification slag generation, collection, storage, transportation, backfilling, filling, utilization, and disposal, including both those resulting from past activities and new ones. The official stated that after the implementation of the \"Standards\", it is expected that 8 million tons of gasification slag can be reduced each year (about 10% of the current total amount of gasification slag), thereby reducing the costs associated with the utilization and disposal of such slag at its source.
