Abstract: Based on differences in the internal organization and thermal characteristics of industrial sludge, the main heat source or cementing agent is provided during the manufacture of biofuel briquettes. This study thus discusses the producibility and flammability of biofuel briquettes, and proposes the optimal formula for producing biofuel briquettes from industrial sludge. The experimental results demonstrated that food processing sludge and sewage sludge can offer excellent calorific value, combustion rate and flame temperature. Moreover, pulp sludge and sewage sludge can provide cementing properties. The four industrial sludge, including food processing sludge, pulp sludge, textile sludge and sewage sludge, can reach the surface combustion stage at 83°C, and can begin stable burning at 177–247°C. The corresponding temperature of maximum weight loss is 250–351°C. Considering the manufacturability, stability and combustion characteristics of biofuel briquettes produced from industrial sludge, the recommended appropriate additions of food processing sludge, pulp sludge, textile sludge and sewage sludge are 30–50%, 20–50%, 20–30% and 30–40% of the total mixture, respectively.
