In this work different methodologies from process engineering based on conceptual design and process simulation with ASPEN PLUS; life cycle assessment and waste reduction algorithm are used for energy; and environmental impact assessment of 5 different feedstocks (Palm; Jatropha; Microalgae; Tallow; Waste Cooking Oil) using 3 different technological configurations from industry; such processes with acid catalysis; basic catalysis and cogeneration; at Colombian and Peruvian context. It was found how productivities for process catalyzed with NaOH are comparatively higher (1.007-1.014 kg of Biodiesel per kg of Crude Oil); than those catalyzed with H2SO4 (0.845-0.949 kg of Biodiesel per kg of Crude Oil). The Production costs for basic catalyzed processes (USD/L 0.408-0.505) were higher than those for acid catalyzed processes (USD/L 0.219-0.257). The PEI (Potential Environmental Impact) generated for basic catalyzed; had a PEI per kg between - 0.078 and -0.033; while acid catalyzed -0.031 and -0.025. Finally LCA for jatropha and palm oil process; evidence Ecosystem Quality damage; a Resources damage; a Human Health damage lower for Jatropha oil in comparison to Palm oil. The Jatropha oil; in a basic catalyzed configuration with energy cogeneration is the best alternative of process; environmental and economics by biodiesel production.
