Abstract

The improper disposal of agricultural waste poses significant environmental and health risks, particularly in developing countries like Nigeria. However, this substantial volume of waste also presents economic opportunities for sustainable energy generation. This study investigates the production of eco-friendly briquettes from agricultural waste and optimizes their composition for maximum heating value. Fecal, softwood and hardwood were mixed in a varied proportion. The results show that a mixing ratio of 50% faecal, 50% hardwood waste, and 0% softwood sawdust, with a compression pressure of 100 kPa and particle size of 100 μm, yields the highest heating value (17.51 MJ/kg). Taguchi optimization confirms that the mixing ratio has the most significant influence on heating value, followed by particle size and compression rate. The study’s findings demonstrate the potential of agricultural waste briquettes as a sustainable approach to energy generation to reduces not only environmental pollution but also provides a viable alternative energy source.
