Abstract

Cultivation of microalgae for applications such as fuel, food, pharmaceuticals and farming is a rapidly developing area of research and investment. Whilst microalgae promises to deliver many environmental benefits compared with existing biofuel technology, there are also issues to overcome in relation to wastewater management, emissions control, land use change and responsible development of genetically modified organisms. This review seeks to highlight both the positive and negative impacts of microalgae cultivation, focusing on impacts to the aquatic, atmospheric and terrestrial biospheres that may occur and would need to be managed should the microalgae cultivation industry continue to grow.

  • Microalgae production has proven environmental benefits but also potential adverse impacts related to high water and energy demand, management of wastewater, emission control, land use, and risk of microbial contamination.

    “Microalgae production has proven environmental benefits but also potential adverse impacts related to the high water and energy demand, management of wastewater, emission control, land use and risk of microbial contamination (Usher et al., 2014; Mayers et al., 2016; Béchet et al., 2017).”

    From Current Status of the Algae Production Industry in Europe: An Emerging Sector of the Blue Bioeconomy (2021) · cites this paper as Usher et al., 2014

    The Abstract identifies wastewater management, emissions control and land-use change as issues, while Energy and nutrient supply describes substantial water and energy demands. Viruses, pathogens and parasites discusses contamination risks. The claim overstates the benefits as “proven”: the Abstract says microalgae promises benefits, and Energy and nutrient supply reports mixed environmental comparisons. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
