Lipid production from a microalgae consortium supplemented with porcine wastewater
Keywords:
Lipids, Simulation, BiorefineryAbstract
Microalgae are microorganisms studied for the production of high value products due to their high content of proteins, lipids, carbohydrates and chlorophyll. In this work, the production of lipids from a consortium of Chlorella sp. is evaluated technically and economically, considering 18 scenarios for their production, 9 of them partially supplemented with swine wastewater. An area of 1 ha was considered for biomass cultivation, primary and secondary biomass collection, and lipid extraction. Through simulation in SuperPro Designer v10 software, consumption and production parameters were evaluated. The results show that the production cost is high, ranging from 836.9 US $/kg to 1131.5 US $/kg of lipids produced. The use of wastewater reduces the production cost by approximately 10%. The evaluation of technical and economic parameters allows the implementation of strategies to reduce production costs.
