Advancing Renewable Fuel Production from the Macroalga Ulva lactuca through Integrated Optimization of Biodiesel Yield and Physicochemical Properties

Algae-derived lipids are promising renewable feedstocks for biodiesel production. However, efficient conversion requires optimization of transesterification conditions to maximize biodiesel yield. This study aimed to optimize biodiesel production from Ulva lactuca lipids using potassium hydroxide-catalyzed transesterif...

Biocatalytic upgrading of fusel oil from bioethanol production to levulinate esters as renewable fuel oxygenates

The transition toward a sustainable bioeconomy requires efficient strategies for converting renewable biomass and industrial side streams into value-added chemicals and fuels. Fusel oil is an important coproduct of bioethanol fermentation and levulinic acid (LA), a key platform molecule derived from lignocellulosic bio...

Two-Stage Optimization of Oleic Acid Esterification via Response Surface Methodology and Green Chemistry Metrics Selection for Biodiesel from WCO

Biodiesel production from used cooking oil (WCO) is a sustainable alternative to fossil fuels, but its high free fatty acid (FFA) content (>5 wt %) makes direct basic transesterification difficult. This study presents an integrated two-stage strategy that optimizes the acid esterification of oleic acid (the dominant...

Effect of extraction temperature, time, and solvent type on the oil yield and biodiesel quality of aquatic Azolla pinnata

ABSTRACT Ethiopia has faced significant energy challenges arising from its overreliance on fossil fuels and traditional biomass, which deplete natural resources and hinder sustainable socio-economic development. Biodiesel production from locally available aquatic plant species would offer a feasible and sustainable ene...
