The purpose of the study was to determine how the amount of binder affected the ignition time and rate of burning of fuel briquettes made from a blend of banana (Musa acuminata) and waterlily (Nymphaea lotus Linn.) peels at varying binder ratios (0, 20, 40, 60, and 80% by weight of each feedstock). Before the briquettes were expelled for additional research, the homogenous feedstock was compressed by a hydraulic press at a pressure level of 5 MPas and a dwell period of 20 seconds. The steel cylindrical die had dimensions of 14.21 cm in height and 2.14 cm in diameter. Fixed carbon ranged from 16.68 to 25.38, volatile matter from 50.5 to 56.8, ash from 15.4 to 18.2, and calorific value from 24751 kJ/kg to 25737 kJ/kg, according to the study’s findings. The results of this study are appropriate for domestic and small-scale industrial heating applications since they exceed the standard minimum calorific value of 17000 kj/kg for fuel sources (DIN 51731:1996-10). Because the ash content increased and the calorific value decreased beyond 60%, it can be concluded that the ideal amount of binder recommended for the production of waterlily banana peels’ bonded briquettes is at 60% and below, even though the combustion properties generally improved with an increase in binder concentration. Increasing the binder ratio and decreasing the particle size resulted in a decrease in the burning rate, but it also prolonged the briquettes’ ignition period.
