Evaluating microalgal integrated biorefinery schemes: Empirical controlled growth studies and life cycle assessment

- Marine and freshwater microalgae were comparatively grown varying media nitrate.
- Lipid, starch, and protein contents were quantified.
- LCA assessed energy consumption, GHG emissions, and eutrophication potential.
- Non-lipid fraction composition presented significant trade-offs among endpoints.
- Tailoring species/growth conditions can enable a sustainable algal biorefinery.
