Description of the Related Art Conventionally, coal ash processing in a coal-fired thermal power plant has relied heavily on landfill of a final disposal site and substitution of clay raw materials in a cement plant. However, land acquisition at the final disposal site is becoming difficult, and the cement industry is no longer able to receive coal ash at the coastal cement plant.
It is necessary to expect the inland factory's capacity to accept. As other effective utilization methods, there are various uses such as roadbed materials, civil engineering work, coal mine filling, and building materials, but at present, there is no use that can be processed in large quantities.
