• [Display omitted] ▶ Heterogeneous catalytic elimination of environmental pollutants (waste oil) especially applied to biodiesel industrial processes. ▶ Preparation, characterization, activation, deactivation and regeneration of a novel and commercially applicable environmental heterogeneous catalyst. ▶ Production of biodiesel from clean energy (biomass). ▶ Catalytic reaction in which wastes are converted to useful products. ▶ Environmentally friendly biodisel is produced by this catalyst. A natural porous silica, pumice, was studied as heterogeneous catalyst in the transesterification reaction of sunflower oil and frying oil with methanol for biodiesel production. This low cost natural porous material was subjected to ion exchange with a KOH aqueous solution in order to increase its activity. The dependence of the reaction variables such as temperature, reaction time, catalyst loading and methanol/oil molar ratio were studied using sunflower oil and waste oil as feedstock. Moreover, in order to save production costs, the reusability of the catalyst in the transesterification reaction was studied.
