Incorporating coal as a filler to fabricate polymer composites or as a modifier to enhance the properties of polymeric materials is an important strategy to extend the nonenergy application and sustainability of coal. The literature shows that different process pathways can be used to develop coal/polymer composites owing to different enduses.

Coal can be used in the production of thermal power. Then this thermal helps further to produce electricity. In this process, coal has to be transformed into powder form. The powdered coal is now heated at a very high temperature to turn water into steam. Electricity is generated when the steam turns turbines at high speed. 4. Cement
