A low-cost briquetting machine utilizing locally available
materials was developed to transform agro-wastes into
fuel briquettes. Compaction ratio revealed that 3:1.5 for
sawdust and 3:1 for carbonized rice hull. The percentage
of binder used to attain a result of excellent firmness of
briquettes was 20% for carbonized rice hull and 25%
for sawdust. For the computed utilized heat produced by
the charcoal briquettes using the stove with blower, the
results showed that sawdust had greater heat value than
carbonized rice hull, therefore, the higher the heat value the
