Abstract
Biodiesel production from microalgae is studied in this work by using Aspen Plus as
a simulator of biodiesel production. In addition, the environmental impact assessment is
evaluated in this work by using life cycle assessment method. The results show that
human toxicity is the highest contribution during biodiesel production. Heat and methanol
production are the major cause of human toxicity with 89% and 4.46% of heat and
methanol, respectively. In addition, agricultural land occupation and fossil depletion are
considerable impacts of biodiesel production.
