Scientists at the Reichmann University School of Sustainability have calculated that replacing each kilogram of beef with one kilogram of spirulina algae will prevent 100 kilograms of greenhouse gases and save 340 square meters. m of fertile soil. The research was published in the journal marine biotechnology.
The scientists evaluated the future of Vaxa Impact Nutrition, the modern biotechnological system in Iceland that grows spirulina. The factory runs on renewable energy.
The research team found that the nutritional quality of spirulina produced with this system is superior to beef in terms of protein, essential fatty acids and iron content, and can serve as a healthy, safe and more sustainable alternative to meat in the daily diet.
According to the research, consumers will save approximately 1,400 liters of water on an area of 340 square meters by replacing each kilogram of beef with Icelandic spirulina. m of fertile soils and about 100 kg of greenhouse gases released into the atmosphere. Also, algae can be consumed in various forms such as wet biomass or paste, powder or tablet. For example, you can use Icelandic spirulina powder as an ingredient in smoothies, pasta, pancakes, and baked goods.
