A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. As shown in the Biomass Briquette Production diagram, the PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Biomass Briquettes are one of the most helpful ways of generating energy from waste disposal. Different types of waste have been utilized in order to develop biomass briquettes. The biomass briquette production technology of briquettes is the process of extrusion screw waste or finely shredded wood waste under high pressure.
