Thesis Overview

The project titled "Optimization of biofuel production using microalgae cultivation and lipid extraction techniques in a pilot-scale biorefinery" aims to address the growing need for sustainable and environmentally friendly sources of biofuels. With the increasing global demand for energy and the negative environmental impacts associated with fossil fuel consumption, there is a critical need to develop alternative sources of energy that are renewable and eco-friendly. Microalgae have emerged as a promising candidate for biofuel production due to their high lipid content and rapid growth rate. By cultivating microalgae in a pilot-scale biorefinery, this project seeks to optimize the production of biofuels through efficient lipid extraction techniques. The integration of advanced technologies and processes will be crucial in maximizing the yield of biofuels from microalgae, making the production process economically viable and environmentally sustainable. The research will focus on exploring different cultivation methods for microalgae, including open pond systems and photobioreactors, to determine the most efficient approach for scaling up production in a pilot-scale biorefinery. Additionally, various lipid extraction techniques such as solvent extraction, supercritical fluid extraction, and enzymatic hydrolysis will be evaluated to identify the most effective method for extracting lipids from microalgae biomass. Through a comprehensive analysis of the cultivation and extraction processes, the project aims to optimize the overall biofuel production efficiency and yield. The research will also investigate the impact of key variables such as nutrient availability, light intensity, temperature, and pH on microalgae growth and lipid accumulation. By optimizing these parameters, the project seeks to enhance the productivity and quality of biofuels derived from microalgae. Overall, the project "Optimization of biofuel production using microalgae cultivation and lipid extraction techniques in a pilot-scale biorefinery" represents a significant step towards developing sustainable biofuel production methods that can help reduce greenhouse gas emissions and mitigate the effects of climate change. The findings of this research have the potential to contribute to the advancement of bioenergy technologies and the transition towards a more sustainable energy future.
