Application Of Systems Engineering And Project Management For Algae Photo Bioreactors, Andrew S. Balberchak

Industrial and Manufacturing Engineering

EXECUTIVE SUMMARY

Today there is much talk about different sources for biofuel to replace the decreasing supply of fossil fuels. Algae seem very promising with its abundance across the globe and relatively simple growing conditions. Lipids can be extracted from this organism which is then converted to biofuel. Although biofuel production from algae is not economically viable at this stage, researchers are suggesting using the by-products of algae for supplemental and healthcare use.
