Integrating Algae Cultivation with Waste Leachate Treatment: A Sustainable Solution for Waste Management and Biofuel Production

Coupling the cultivation of algae with the treatment of waste leachate presents a promising and sustainable approach to both waste management and biofuel production. This study examines the quality of biodiesel produced from Chlorella vulgaris cultivated in an open photobioreactor using municipal waste leachate sourced from a stream in District ۱۴, Tehran. The C. vulgaris was grown in BG-۱۱ medium under controlled laboratory conditions, with two primary setups: one with aeration and agitation as a control, and the other subjected to thermal pretreatment. Biodiesel was produced using a ۱.۵% w/w methoxide catalyst solution, composed of methanol and potassium hydroxide, applied through a microwave system. The biodiesel was analyzed for quality parameters, including kinematic viscosity, density, oxidation stability, iodine value, and cetane number, comparing these results to the EN ۱۴۲۱۴ standard for biodiesel quality using BiodieselAnalyzer software. The findings reveal that biodiesel derived from C. vulgaris grown in waste leachate demonstrated the most favorable characteristics among the three conditions evaluated, successfully meeting the EN ۱۴۲۱۴ standard.
