Microalgae can recover greenhouse gases and nutrients from industrial waste. This technology can be used to reduce climate footprint and eutrophication. Lina Mattsson’s dissertation in ecology shows that microalgae can be used also in the Nordic climate, which has previously been considered a challenge as the algae are dependent on heat and sunlight.
The technology, which Linnaeus University’s research group Algoland has worked with for a long time, involves leading emissions into cultivation containers, so-called photobioreactors, containing microalgae. Through photosynthesis, the algae can recover substances like carbon dioxide, nitrogen, and phosphorus, and transform these into valuable biomass instead of having them disperse in nature. The green algal biomass mass is valuable as it contains large quantities of proteins, carbohydrates, and lipids.
“The algal biomass can be used for products that are of benefit to society, like biofuel, feed, cosmetics, and food supplements. In this way, microalgae can contribute to solutions for a more circular society”, explains Lina Mattsson, researcher in ecology.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
