Sustainable approach for biodiesel production and wastewater treatment by cultivating Pleusrastrum insigne in wastewater

The globalized modern world has been confronted with some of the most challenging problems, most of which arises from human activities. Overexploitation of fossil fuels which leads energy and environmental crisis, loss of aquatic ecosystem due to improper disposal of household and industrial waste into water bodies constitute some of the biggest emerging global problems. In this study, an unconventional and sustainable approach to produce biodiesel was analyzed by growing Pleurastrum insigne in wastewater. The growth of P.insigne in wastewater in turn significantly reduce the amount of biological oxygen demand, total phosphorus content and total nitrogen content in the wastewater. Production of biodiesel conforming to international standards was predicted from P. insigne cultivated in wastewater confirming the effectiveness of combining wastewater treatment and biodiesel production.
