Case Study - Mengdong Energy Group
Source: Date: 10.01.22

Mengdong Energy Group's circular industrial chain focuses on circular and comprehensive utilization of lignite with coal, electricity and aluminum as main associated industries and coal-to-chemicals, building material and eco-agriculture as future auxiliary industries. Aimed at "less consumption, re-utilization and resource optimization", it will achieve low consumption, low emission and high efficiency of the industries.
  
By improving the accuracy of geological exploration, optimizing design and mining scheme, applying advanced mining equipment to coalfield and shifting from oil-driven mining to electrical mining, Mengdong Energy Group has considerably increased the coal recovery and effectively reduced resource consumption and hazard discharge. Coal is the basis for the circular industrial chain of Mengdong Energy Group. Coal with low heat value is locally converted through the two industrial chains of "low-heat-value coal - mine-mouth power plant" and "low-heat-value coal - self-supply power plant - smelting of non-ferrous metals", while coal with medium heat value is converted into electricity and coal-chemical products by building the two industrial chains of "medium-heat-value coal - railway - rail-mouth power plant" and "medium-heat-value coal - railway - coal-chemical", thus achieving diversified utilization of coal resources. Meanwhile, weathered coal is used to producepotassium humate, sodium humate, fulvic acid and other products.
 
By means of multiple portfolios including cross-industrial cooperation or industrial chain extension, Mengdong Energy Group has enhanced resource efficiency on a large scale, across multiple regions and by a large margin.
