Of late, some biological wastes have proven to be reliable candidates in promoting the economic viability of developing polymeric composites. However, the field-proven reliability prediction of such materials during service life requires extensive characterization. In this research, the influence of 75 µm bovine femur ash subjected to two-step calcination process on spectroscopic, wear, mechanical, water absorbent and biocorrosive properties of epoxy/femur waste biocomposites was investigated. The test materials were developed via open mould casting and subjected to preferred characterizations apropos of the abovementioned properties. Elemental constituents of the biocomposites and the ash were determined by energy dispersive x-ray spectroscopy with scanning electron microscopy and x-ray fluorescence spectroscopy, respectively. The investigated properties were studied dependent on predetermined volume fractions of the ash in epoxy matrix. Observations from the experimental results revealed that properties’ enhancement was not specific to either low or high volume fraction of the ash in epoxy. Different properties were enhanced at different volume fractions of the ash. Nonetheless, one biocomposite approaching intermediate volume faction of the ash used, exhibited optimum combination of the investigated properties. This is a clear indication that bovine femur waste can be successfully exploited for engineering applications, especially in the areas of materials development.
