A revolutionary food production: minimal environmental footprint and negative carbon footprint

Vaxa Impact Nutrition is a high-tech company that offers a solution to convert energy into food (Energy to Food – E2F) in an efficient way.

The project was the first in the world to use high-tech continuous monitoring, data processing, and automatic system adaptation in order to obtain optimal results in the cultivation of microalgae, with any type of algae and without the use of pesticides or antibiotics.

In order to provide a precise flow and save even more water in its production plant, Vaxa installed BT-Maric constant flow limiters.

Vaxa Impact Nutrition converts clean energy into food, producing the most sustainable microalgae in the world, rich in omega-3 and proteins.

Additionally, the operations have a negative carbon footprint, which means that more carbon dioxide is converted into oxygen than is associated with the operation. Located in Iceland, the plant is integrated into one of the world’s largest geothermal power plants and turns the plant’s waste into sustainable resources for the production process. Using clean energy, hot and cold water and the natural carbon emissions of the geothermal power plant to produce microalgae makes the project fully sustainable and carbon negative. 

According to Kristinn, the director of Vaxa, “the fundamental reason for this project is that the founders realized that there soon won’t be enough food to feed the whole world due to the demographic growth and the increase of food consumption per capita. Today, there is enough food, but the reason for hunger in some places is that we do not share food well. It is a global problem and the founders wanted to find a new way to produce food. With this method, a kilo of protein can be cultivated with 1,500 times less soil and 500 times less water than what is necessary to make soja grow. This could be one of the keys to solving food problems in the world.”

According to the article “The Future of Feed: Integrating Technologies to Decouple Feed Production from Environmental Impacts” (published on April 16th, 2019 in Industrial Biotechnology Vol.15, n°2), “demographic growth, an expanding middle class and a global change in food preferences have led to a sustainable demand for animal-based products. Given that animal-based products play a vital role in the human diet, their consumption should still increase. However, livestock depends highly on soybeans for feed. The environmental consequences of soy production and the obstacles to expanding land for soy production cast doubt on the sustainability of the food system. It is imperative to reduce the future demand for soy using other food resources of similar nutritional values and separating food production (for livestock) from the ecological pressures.”
