【 摘 要 】

The study evaluated the physical and mechanical properties of briquettes made from water lettuce (Pistia stratiotes) at different binder ratios of banana peels, yam peels and cassava peels at compaction pressure of 10 MPa. The water lettuce was collected from Amassoma River, cleaned and sun-dried. Binder levels of 10, 20, 30, 40 and 50% by weight of each feedstock were used. A steel cylindrical die of dimension 17.0 mm height and 6.0 mm diameter was used to produce briquettes using hydraulic press with dwell time of 45 seconds. The ASAE standard methods were used to determine the physical properties of briquettes. The obtained data was statistically analysed using Analysis of Variance (ANOVA) and simple statistical tools such as means and standard errors. The obtained values for initial bulk density of milled uncompressed mixture of water lettuce, yam peels, cassava peels and banana peels at different binder ratios were 142.39 kg/m3, 221.26 kg/m3, 208.30 kg/m3 and 243.54 kg/m3. Compressive density of briquettes at different binder proportions showed significant difference at P
