Low-Cost Bioprocessing Technologies for Algae-Based Carbon Sequestration

Abstract

Algae-based carbon sequestration has emerged as a promising technology for mitigating global climate change by capturing carbon dioxide (CO2) from the atmosphere. The process involves the use of algae, which photosynthesize and convert CO2 into organic carbon, aiding in the reduction of atmospheric greenhouse gases. However, one of the primary challenges to widespread adoption is the high cost of bioprocessing technologies required to cultivate, harvest, and process algae efficiently. This paper explores the potential of lowcost bioprocessing technologies for algae-based carbon sequestration, focusing on innovative methods that reduce operational expenses without compromising effectiveness. We discuss various approaches, including photobioreactor optimization, alternative nutrient sources, bioflocculation, and low-cost harvesting methods, alongside their impact on system efficiency and scalability. The findings indicate that such technologies can enhance the economic feasibility of algae-based carbon sequestration, making it a more viable solution for large-scale CO2 capture. The paper also highlights the importance of technological advancements in reducing energy consumption, improving productivity, and fostering the commercialization of algae-based carbon sequestration.
