ABSTRACT
Biomass Briquetting can address waste problems, reduce air pollution from direct open air
burning and also reduce dependence on fossil fuels for heat generation. Dry leaves have been
shown to have high calorific values; therefore the purpose of this study is to determine the effects
of some binders on the physical and combustion properties of dried leaves briquettes. Dried
leaves were mixed with binders such as clay, starch and Arabic gum separately at different ratios
of 10%, 20%, 30% and 40%, and made into briquettes using a manual press with a hydraulic jack
of 20 tons. Physical and combustion properties of these briquettes were obtained using different
methods prescribed by other researchers. From the results of the properties tested, briquettes
made from dried leaves and gum at 40% of binder was most resistant to water. Dried leaves and
clay at 40% had the highest relative density of 0.7977g/cm3. Dried leaves and starch had a
relative density at 40%, 0.4640g/cm3 while briquettes with gum binder had 30%, 0.4030g/cm3.
Dried leaves and gum at 40% had the highest volatile matter of 84.110% and the highest heating
value of 30.5118MJ/kg at 10%. Briquettes at this ratio failed to hold, because of its low
durability. The high ash content of briquettes bonded with clay 16.353% to 34.487% made it
difficult to ignite, due to the presence of non combustible matter. Dried leaves bonded with
starch at 20% had high heating value of 30.2189, and was able to withstand shattering with
durability of 81.752% and high relaxation ratio of 1.7427. It can then be considered as the best
binder in this study.
