Abstract
The current study sets out to optimize resource utilization by coupling data envelopment analysis (DEA) with the analytical hierarchy process (AHP) methodology to model sustainable binder choice without experimenting available binders. The results of the AHP showed that the cardboard pulp binder was the preferred material to use. Cardboard pulp binder, palm kernel decanter cake, and charred palm kernel shells in a ratio of 10: 20:70 was the used to manufacture composite briquettes. The values obtained for calorific value, specific fuel consumption, and average burning rate were 22.72 MJ/kg, 2.21 kg/L, and 4.87 g/min respectively for the optimal choice. The briquettes produced in this study promotes circular economy and provides a novel framework to address cooking energy poverty issues through the manufacturing of waste-based biofuels. To the best of our knowledge, this is the first study in sub-Saharan Africa to use these waste resources to create composite briquettes.
