wants to eat healthy and save the planet? Replace beef with spirulina! -Bio Pass

Asaf Tzachor, in cooperation with an international team of scientists, analyzed the most advanced biotechnology systems for cultivating spirulina. The system is designed and operated by Vaxa Impact Nutrition and is located in Iceland's ON Power Geothermal Park. It benefits from the resource flow of Hellisheidi power stations, including renewable electricity for lighting and electricity use, hot and cold water flow for thermal management, fresh water for cultivation and carbon dioxide for biological fixation.

According to a new analysis led by Dr. Asaf Tzachor, School of Sustainable Development, Rickman University, there will be a state-of-the-art facility in the future.Iceland, can be usedcultivation of spirulinato replace beef. The analysis found that every kilogram of spirulina instead of one kilogram of beef can reduce nearly 100 kilograms of greenhouse gas emissions, saving 340 square meters of land and 1400 liters of water.

According to laboratory analysis, researchers found that the nutritional content of spirulina agricultural products is better than beef in terms of protein, essential fatty acids and iron, and can be used as a healthy, safe and more sustainable meat substitute in the daily diet..

for every kilogram of beef replaced by Icelandic spirulina, consumers will save about 1400 liters of water, 340 square meters of fertile land and reduce nearly 100 kilograms of greenhouse gas emissions into the atmosphere, according to the study. In addition, algae can be consumed in different forms, including as wet biomass, or in the form of pastes, powders or pills. For example, people can use Icelandic spirulina powder as an ingredient for pasta, pancakes and pastries, or drink an Icelandic spirulina milkshake..

Although the role of meat in human diet is beneficial, its ecological footprint is quite large and harmful. Raising beef cattle requires arable land and feed reserves, and emits greenhouse gases into the atmosphere, leading to climate change and global warming. One kilogram of beef requires about 1450 liters of water and 340 square meters of fertile land. In addition, producing one kilogram of beef produces about 100 kilograms of greenhouse gases..

As the demand for animal-derived proteins grows, so does the damage caused by animal husbandry. In response, humans are looking for new ways to ensure their nutritional safety, including alternative sources of protein, the supply of vitamins and essential minerals.

algae, especially spirulina, are considered to be one of the most effective food producers on the planet and can be cultivated using different techniques. In this study, Spirulina was cultivated in a closed, controlled system, using advanced photon management methods (controlled exposure to the required wavelength), completely isolated from the harsh environment of Iceland.

this biotechnology system is extremely flexible to fluctuations in environmental and climatic conditions. It can be deployed in different parts of the world in a modular manner. In addition, Spirulina is an autotrophs that rely on photosynthesis and the supply of carbon dioxide. Therefore, unlike many other alternative protein sources, growing this food source can eliminate greenhouse gases in the atmosphere and mitigate climate change.

Rickman University, said: "Nutritional security, climate mitigation and adaptation can go hand in hand. All consumers have to do is add a little Icelandic spirulina to their meals and diets, not beef. It is healthier, safer and more sustainable. No matter what we want the world to change, it should be reflected in our dietary choices."

the study was carried out by Dr. Asaf Tzachor and researchers from the Danish Institute of Technology, the University of Iceland and the Matis Iceland..
