    Dynamic changes in environmental conditions had necessitated continuous research towards the development of innovative structural composites with enhanced properties. To produce functional concrete-based composites, there is a need for structural modification using reinforcing fillers that could improve the strength and toughness of the composites. Agricultural exercise creates many nonedible components which constitute environmental nuisances owing to their little or no economic value. However, processing such components into useful reinforcing fillers in concrete and other matrices for composite development encourages a wealth creation from waste, environmental hygiene and ecofriendly materials for engineering applications. This study focuses only on the production of nanoparticles which can be used as fillers in composite development. Nanoparticles were produced from the flamboyant pods using a disc and optimised ball milling technique. Pods were pulverised using a disc miller and the powders obtained were ball milled at varied charge ratios and velocities to produce reinforcing nanoparticles. Particles obtained in each of the milling exercises were analysed and 2 functional interaction response surface model was developed to optimise the milling parameters and particle sizes. Result obtained indicated a decrease in size of the flamboyant pod particles as milling durations and charge ratios increase. P value of the model <0.0001 which is much less than 0.05 shows that the model is significant in explaining dependence of the particle sizes on the milling parameters. Hence, the developed model affirms that a minimum size of 3.5209 nm of the flamboyant pod particles can be obtained without agglomeration of particles when milling at 10 charge ratios for 17 hours 29 minutes
