Comparative life-cycle assessment of reverse osmosis and microalgae-based treatment for hypersaline oilfield produced water
Published 2025“…Furthermore, the microalgae system provided a net credit for fossil resource scarcity (−0.193 kg oil-eq) and reduced freshwater eutrophication by 60 % relative to RO. However, it also presented important trade-offs, including a 2.19-fold increase in land use, a 9.7-fold increase in marine eutrophication driven by the nitrogen content of the glucose feedstock, and higher human carcinogenic toxicity. …”
