MiAlgae aims to revolutionize the current livestock and pet feed industries by producing microalgae rich in polyunsaturated fatty acids (PUFAs) to offer as a replacement to fishmeal in feed. 🚫🐟 Feed suppliers are in need of this alternative to fishmeal due to declining wild fish stocks and rising demand for Omega-3s. MiAlgae has developed an environmentally beneficial, effective, and simple solution of producing microalgae which delivers the required nutrients to livestock and pets without the need for fish. ♻️ Our zero-waste solution recycles the nutritional co-products from whisky production to grow Omega-3 rich microalgae, returning clean water in the process. 🌍 Our mission is to create a product that will contribute substantially towards the sustainable production of livestock, a prerequisite to fulfilling the needs of the growing world population. 💡Please check us out and follow us on: -https://www.twitter.com/mialgae -https://www.instagram.com/mialgae/
