Closing nutrient loop Circular economy Collaboration Community building Waste Animal-sourced food Alternative protein Consumer choice Women empowerment

Anemia is a condition caused by a lack of iron in the body and a major public health problem that affects millions of people around the world. It leads to fatigue, weakness, and impaired cognitive function, among other symptoms. One of the main sources of iron for humans is red meat, which is rich in iron. However, the production of red meat is resource-intensive and has a significant environmental impact. Upcycling wasted animal blood from slaughterhouses could act as a better alternative, and sustainable solution to the problem of iron deficiency anemia. The scabilitity of this innovation would include collecting the blood from slaughterhouses and processing it into a form that could be easily consumed. This can be done through dehydration, sterilization, and the addition of other nutrients to create a nutrient-rich supplement. Not only is this approach more sustainable than traditional methods of iron supplementation, it takes a food systems approach to reduce the loss of a highly-needed nutrient and can improve animal welfare. Using animal blood that would otherwise be discarded could help to reduce the strain on our planet's resources and minimize the environmental impact of food production.
