Olusegun David Samuel,Modestus O. Okwu,Oluwayomi J. Oyejide,Ebrahim Taghinezhad,Asif Afzal,Mohammad Hossein Kaveh +5 more
TL;DR: In this paper, the grey wolf optimizer (GWO) was used to predict the yield of waste sunflower oil methyl ester (WSOME)/biodiesel (BD) production from WSO and the least square regression method was accosted to correlate the density of (0%KS+100%BD), (5PKS+ 95%BD, (50%KS +50BD) and (100%KS−0%BD) blends.
Journal ArticleDOI
Comparison of Response Surface Methodology (RSM) and Artificial Neural Network (ANN) in modelling of waste coconut oil ethyl esters production
TL;DR: The attributes of renewability and environmental friendliness have made ethanol a preferable alternative to methanol in the production of biodiesel from lipid feedstocks as discussed by the authors. But, for the first time, this...

Production of fatty acid ethyl esters from rubber seed oil in hydrodynamic cavitation reactor: Study of reaction parameters and some fuel properties
TL;DR: In this article, the authors adopted HCR to produce ethyl esters (biodiesel) from low FFA rubber seed oil (RSO), and the effects of transesterification variables namely catalyst dosage (KOH), reaction time (30-50 min) and ethanol/RSO molar ratio (3.5 7.0) were examined on the biodiesel yield.
Journal ArticleDOI
Evaluating challenges to implementing eco-innovation for freight logistics sustainability in Nigeria
TL;DR: In this paper, the authors identify the challenges to implementing eco-innovation practices for freight logistics sustainability to aid management to take informed decisions to overcome these challenges before the environmental burdens become critical.
