Certainly clever, but I can't see this catching on. There's just too much of the "icky factor" in it. The trend seems to be towards using *fewer* animal products, not more.

For many years it was common to use animal derived additives in lime based renders. Blood, hair and manure were all used and still are when working on historic buildings. In this case the blood seems to being used as a bonding agent whereas in traditional construction it was used to improve the workability of the render. Just goes to show there is nothing new under the sun.

mooseman, "icky factor"? THINK about that. When an animal is butchered, blood is a generally considered a 'byproduct' and discarded/wasted. This process takes a byproduct and converts into a sanitary, useful, stable and durable product.

Most interesting idea, too bad that making food out of the blood is much better use of it.

The Vegies and Vegans have left the building.....never to return.

The blood from butchered animals is not currently being wasted. It is used to make various animal feeds and fertilizer products.
at least in industrialized countries, they use blood for fertilizer, animal food, etc
ew but still
and in some far off primitive country, will they have molds, ovens, the other chemicals.?

This is wrong on so many levels-chief among them would be the subsidizing the meat industry-a very unsustainable food using 100 times the land and contributing to 25% of the greenhouse gasses. I'm with Mike Hallett, the Veggies and Vegans have vacated the building...never to be seen again.

While there is an ick factor, what is interesting is this person has looked at an unconventional material and investigated it's properties in ways never thought of. What else is out there? I'm still jazzed about hempcrete and wish there was some way to cut thru the cr*p about hemp to get it on the market in the US in a big way.

The heat causes the protein to coagulate but why wouldn't it rot over time?
Interesting idea though.
If you look at the amount of crop you would need to replace animals in our diet (and if you don't calculate animal feed as if every bit of it comes from dedicated cropland--much of it comes from human crop waste and processing byproducts), meat actually takes up less land than the equivalent in vegetative calories and nutrients.
Blood used in animal feed will probably become less popular and less legal with mad cow disease and new potential diseases.
The Hajj probably results in a lot of spare blood. Muslims are not supposed to consume it but they don't seem to have any shortage of sand. With some desalination they might get into the brick production and export business.
