Abstract

Sewage sludge is one of the most polluting wastes that affect the environment, which contains organic and inorganic pollutants released into the surroundings. Using non-renewable energy for the engine also releases large amounts of pollutants results from combustion products was other issues to the environment. The decline of non-renewable energy sources, such as natural gas, fossil fuel, and petroleum made the world increase the production of alternative fuels like waste-derived fuels. Recently, biodiesel production developed from edible oil to cover the depilation of non-renewable energy supply. But it has also become a significant challenge for food security. Therefore, finding other potential opportunities for lipid extraction is crucial. Algae and sludge conversion presented by recent studies seem to be a promising method. The paper presents the extraction and optimization of lipids from blended sludge and algae for biodiesel production. The procedure of the study was a characterization of algal and sludge wastes, the extraction of the lipid component by Soxhlet extraction, and the parameters optimization for maximum oil yield obtain. Temperature, extraction time, and solvents were the basic factor affect oil extraction yield. In the optimization 80 temperature, 6hrs time and hexane solvent results in 61% oil extraction yield which maximum point. Algae and wastewater sludge high potential of lipid and can be substitute edible oil supplies for biodiesel production.
