Nordic microalgae cleans wastewater and produces biodiesel

A further study, written by the researcher of the University of UmeƄ Lorenza Ferro, highlights the importance of microalgae in the environment and the considerable possibilities that these plants offer in the field of biofuel production.

Biomass made of algae has been increasingly taken into account and used in recent years for the production of biofuels because these microorganisms can form and store large amounts of lipids. The latter can then be converted into biodiesel. As if that were not enough, the same microalgae can be very useful for purifying wastewater because the nitrogen and phosphorus in them can also be used to feed the microalgae.

In the Nordic countries of Europe, however, the use of microalgae is very limited: this environment is in fact characterized by very long winters with the sun peeping out much less often than in the regions further south and this causes significant problems in the use of microalgae. The researcher shows, in her study, that in such contexts using native strains of Nordic microalgae can be the solution.

“My work has shown that local Nordic microalgae are much better than standard varieties. Our Nordic strains are currently tested under “real conditions” with the aim of extending the growth period until late autumn or even winter,” says the researcher.
