    The rate and cost of biodiesel production has been hampered by the nature of the catalysts and feedstocks used. The bifunctional catalyst prepared from the mixture of 40 wt% sulphonated corncob (acid source) and 60 wt. % calcined cowbone (base source) was employed in the kinetic studies of the waste cooking oil transesterification for biodiesel production. The kinetic reaction tends towards fitting into a pseudo-first order reaction with activation energy (Ea) and collision factor of 21.4833 kJ/mol and 0.4909𝑠−1 , respectively. The effects of each parameter on the production of biodiesel were highlighted. The physicochemical properties such as the flashpoint (403 K), pour point (281.2 K) and cloud point (283.11 K) of the synthesized biodiesel were also obtained. Furthermore, a test on reusability was performed for the bifunctional catalyst and it was found to retain its catalytic potential until the fifth cycle with a percentage catalyst loss of 7 %. This result indicates that the bifunctional catalyst was effective in the kinetic study of the transesterification of waste cooking oil.
