Danish algae could be the future’s sustainable feed protein

In future, algae may become the primary source of protein for feed, thus replacing the imported soya used today. There is indeed potential in Danish-grown microalgae. The potential is to be investigated over the next years through the ReMAPP project, which is supported by the Danish Innovation Fund.

Cultivated algae will be supplied with CO2 and nutrients from the biogas industry’s side-streams. The objective of the project is to produce proteins from algae from land usage which is up to ten times less than with conventional feed crops.

"Microalgae have long been in the scientific spotlight as they can achieve very high growth rates and can be grown on land that is otherwise unsuitable for agriculture. The algae will be a mixed culture adapted to the Danish climate, which offers robust production and a long growing season,” says Jesper Mazanti Aaslyng who is heading up the project at the Technological Institute.

The ReMAPP project
The ReMAPP project will develop its first trial fields with algae in tubular bags at the Technological Institute in Taastrup after which an 800 sq.m. system will be established at the biogas plant, NGF Nature Energy Holsted in South Jutland, which will produce 13 million m3 of biogas per year. The project has a total budget of DKK 26 million and will run until the end of 2022.
