Life cycle assessment of Moringa oleifera derived biodiesel: Energy efficiency, CO₂ intensity and environmental impacts

Abstract

This paper performs a thorough cradle to tank life cycle assessment to examine environmental impacts of Moringa oleifera derived biodiesel. Attributional LCA according to ISO 14040-44, using CML-IA baseline method, was conducted. Furthermore, Biodiesel versus petrodiesel comparison was undertaken.Moringa oleifera derived biodiesel shows a GWP of 39.94 gCO 2 eq/MJ of biodiesel, which presents a reduction of 52.34%, compared to petrodiesel. It revealed an EROEI value of 1.48, which can reach 3.20 with allocation applying, presenting an energy saving over petrodiesel of 53%. In addition, Ozone layer depletion impact of Moringa based biodiesel is lower than that of petrodiesel. This good performance notwithstanding, Moringa oleifera derived biodiesel exhibits high environmental impacts in terms of Abiotic Depletion of elements, Human Toxicity, Fresh water aquatic eco-

Moringa oleifera (drumstick tree)—nutraceutical, cosmetological and medicinal importance: a review

“…This is due to the use of greenhouse gas-producing agricultural machinery, which is used more frequently during irrigation. Biodiesel from M. oleifera oilseeds can greatly help in the fight against global warming (Amouri et al, 2023).…”
