Characterization of briquettes developed from banana peels, pineapple peels and water hyacinth

Uganda's energy needs are heavily reliant on biomass sources. This dependency of Uganda's burgeoning population on biomass for household and commercial purposes is posing pressure on natural resources such as forests. This study was carried out to investigate the utilization of some of the country's highly produced agricultural waste for the creation of biofuels. Methods: Pineapple peels, banana peels and water hyacinth were utilized for generation of both carbonized and uncarbonized briquettes. Physical properties and calorific values for the developed briquettes were determined through thermogravimetric analysis and using a bomb calorimeter. Results and conclusion: Pineapple peel carbonized briquettes had the highest calorific value (25.08 MJ/kg) followed by a composite of banana peels and pineapple peels (22.77 MJ/kg). The moisture content for briquettes ranged between 3.9 to 18.65%. Uncarbonized briquettes had higher volatile matter (ranging between 62.83 and 75.1%) than carbonized briquettes (ranging between 22.01 and 24.74%). Uncarbonized briquettes had shorter boiling time (ranging between 27 and 36 minutes for 2.5 liters) than carbonized briquettes (ranging between 26 and 41 minutes). Water hyacinth alone produced briquettes with low calorific values (16.22 MJ/kg), however, calorific values increased when mixed with banana (20.79 MJ/kg) or pineapple peels (20.55 MJ/kg). The findings reveal crucial information on how agricultural wastes might be used to augment the energy sources pool in order to protect the environment and creating social stability in the community.
