In order to reduce the fossil fuel usage, to meet huge energy demand and lessen air pollution, a green, clean and sustainable biofuel is the only alternative. Biodiesel production becomes cheaper when we use a cheap precursor, eco-friendly catalyst and a proper process. Pig tallow from the meat industry containing high fatty acid can be utilized as an effective precursor for biodiesel preparation. This study produced biodiesel from pig tallow oil via ultrasonic assisted and CuO catalysed two-step esterification process. Cinnamomum tamala (C. tamala) extract was utilized for CuO nanoparticles preparation and characterized using infra-red spectra, x-ray diffraction, particle size distribution, scanning and transmission electron microscopy. Biodiesel production was modelled using Box-Behnken design (BBD) and artificial neural network (ANN), in the variables range of ultrasonication (US) time (20–40 min), CuO nanocatalyst load (1–3 wt%), and the methanol to pre-treated PTO molar ratio (10:1–30:1). Statistical analysis proved that the ANN modelling was better than BBD. Optimal yield of 97.82% obtained using Genetic Algorithm (GA) at US time: 35.36 min, CuO catalyst load: 2.07 wt%, and the molar ratio: 29.87:1. Comparison with previous studies proved that ultrasonication significantly reduced the CuO nanocatalyst load, and increased the molar ratio and improved the process.
