An alternative biorefinery approach to address microalgal seasonality: blending with spent coffee grounds
Open accessAbstract
An effective method for the production of fuels and chemicals from microalgae is to ferment the carbohydrate fraction, extract the lipids and convert the resulting solids through hydrothermal liquefaction (HTL).

Different approaches are discussed in recent scientific literature to improve economic issues, such as using co-HTL to cover algal reduced productivity in colder seasons or algal cultivation costs and previously extracting valuable compounds from algae then converting residual biomass into biofuel.
“Different approaches are also discussed in the recent scientific literature and aim to improve the economic issues, such as using the co-HTL process to cover algal reduced productivity in colder seasons [87, 88] or algal cultivation costs [89] and previously extracting valuable compounds from the algae and then converting the residual biomass into biofuel [90–92].”

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.
