Annually, people consume over 250,000,000 tons of meat worldwide1. With all of this meat being produced and eaten, blood has become one of the most common waste materials in the world. Blood bricks are a new and innovative (and somewhat disgusting) building material developed by architect Jack Munro that utilizes this waste. Sand and blood are used in place of mud and water to create this earthen brick that can be used as a low cost building material.
Blood is mixed with sand and preservatives and then baked at 160°F for an hour to produce a structurally stable and waterproof brick2. Munro has done many experiments with this material and has found it to be as stable as traditional mud bricks, if not more so. He has also experimented with other methods of using blood in construction. One idea was to pour tons of blood over a sand dune with protective objects left in areas where you want to create apertures in the final structure. Once the blood has coagulated into a shell over the dune, wind is allowed to blow away the loose sand underneath leaving a large structure of blood and sand2. But even if this is a cheap and eco-friendly building material, will people accept it?
In many cultures using blood is considered to be disgusting or taboo. Islamic cultures consider blood to be Najis, or dirty, and even contact with blood is taboo3. Judaism considers blood to carry the life of the animal and thus cannot be consumed by humans3. In some cases, cultural taboos against blood, like these, may not be an issue as the blood here is not being eaten. But even so, Munro may find it hard to convince people to live in a house made out of blood and sand.
