Abstract

original image

Algal fuel cells: Repeated nutrient recycling is demonstrated by reusing the aqueous phase obtained from the hydrothermal liquefaction (HTL) of microalgae. This is achieved, for the first time, by performing a complete set of four continuous growth–HTL cycles. Results show similar growth rates in each cycle, the potential of nutrient reduction, as well as cell morphology changes. This study demonstrates progress towards the standalone operation of algae biorefineries.
