Abstract
The influence of torrefaction pretreatment on the properties of briquettes made from the blends of sawdust (SD) and cassava peel (CP) was studied. These feedstocks were combined at mixing ratios of 90/10, 70/30, 50/50, 30/70 and 10/90 for untreated and torrefied conditions. The physical and combustion properties were determined using standard methods. Results obtained at all mixing ratios show that the fixed carbon, volatile ignitability, and calorific value increase with the increase in the torrefaction temperature. Further results show that the physical and mechanical properties yield better result through water preconditioning. This work established that high quality briquettes with improved strength and caloric value could be produced from discarded SD and torrefied CP.
