Food‐processing sludge (FPSs) have high moisture content (approximately 80–90%) and odor, and therefore can easily become a potential environmental hazard. However, FPS has a higher calorific value and a lower ash content (dry basis). This study assessed the fuel briquettes potential of different food‐processing sludge‐derived fuels (FPSDFs) through analysis of their FPSs composition and combustion characteristics. The experimental results showed that FPSs were weak acid with high concentrations of chloride ions. Moreover, the calorific value of FPSs (18.59–25.70 MJ/kg, dry basis) could reach up to 72.4–100.1% of that of coal. The formability of FPSDFs was significantly related to FPSs type, and FPSDFs were characterized by high temperature (900–1100°C), flammability, low‐moisture regain (8–14%) and lightweight (0.7–0.9 g/cm 3 , dry basis). Considering fuel potential revealed that FPSs from the dairy and beverage industries was the most suitable material for manufacturing fuel. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1790–1795, 2015
