Abstract: A pyrolyzer was fabricated for the collection of liquid products from the pyrolysis of untreated bamboo saw dusts from UPV-Bamboo Enterprise Development Project. Collection and analysis of the liquid products were performed for two temperature ranges from 490-500oC and 550-560oC. Based on the generated method from the fabricated pyrolyzer, the yield ranges from 8% to 16%.The analyses included the physicochemical properties of the liquid products such as the pH, viscosity, density, and heating value. For temperature ranges of 490-500oC and 550-560oC, mean values of pH were 4.47 and 4.30; density values were 1087.37 kg/m3 and 1066.76 kg/m3 ; viscosity values were 1.32 mm2/s and 1.62 mm2/s; and heating values were 1.99 MJ/kg and 2.51 MJ/kg respectively. The results showed that there was no significant difference in the pH, viscosity, calorific value, and density of the untreated bamboo saw dust with different operating temperatures of the pyrolyzer equipment using a One-Way Analysis of Variance (ANOVA) since the p-value of each test were greater than the specified α = 0.05 level of signif- icance.
