Microalgae are not only carbon binders, but also potent environmental cleaners. Their ability to biosorb enables them to filter pollutants such as heavy metals from contaminated waters. This makes them a promising solution in water treatment processes and in the bioremediation of industrial waste gases, where they can absorb pollutants such as sulphur and nitrogen oxides.

One forward-looking area of microalgae research is their application in biofuel production. Because microalgae can efficiently convert sunlight into chemical energy, they offer a renewable alternative to fossil fuels. Their cultivation as a raw material source could accelerate the transition to sustainable energy sources.

In agriculture, microalgae offer solutions for soil improvement. Their ability to fix nitrogen and convert it into a form available to plants makes them a potent biofertiliser. Microalgae are also of great importance in aquaculture. As a protein-rich food source, they serve as a high-quality fish feed that improves both the growth rate and the health of the fish. Through their sustainable production, microalgae can help reduce the need for wild-caught fishmeal and thus reduce the overfishing of our oceans.

With the growing world population, microalgae have also come into focus as a source of food. They can be cultivated in wastewater, which conserves water resources. They also serve as a basis for biofuels, offering solutions for the food-energy-water nexus.
