Biostone: Biological Concrete made from sand, bacteria, and urine

Now here is an interesting biological product that could eventually be used to replace standard concrete while lowering our CO2 emissions. Yeah, cement production is not the most environmentally friendly thing in the world, to say the least. Anyway, the product is called "biostone" and it plans on putting your urine to better use; ha! The combination of this biological concrete uses sand, bacteria, and urine.

The procedure for creating this biostone/biological concrete involves filling a mold (that has the desired shape of the product) with sand before pumping a bacteria solution of bascillus pasterurii into the mold. From this point, it will set overnight. On the next day, a solution of urea, calcium chloride and nutrient broth is then pumped into the mold. As was stated on the actual page I just read: "The bacteria uses the urea as energy to absorb the calcium chloride and convert it into calcium carbonate, a cement-like mixture that binds the sand together within the mold." You can read more about this, here:

One of the YouTube videos is located here:

Of course, this particular method would not interest the common consumer nor would they probably like the idea of buying products that are made from urine and bacteria. LOL! On a good note, this is a step in the right direction since the idea behind this biological concrete/biostone can be expanded upon and hopefully be used later on to build houses, etc., and make industrial manufacturing more environmentally friendly and sustainable. I just thought this was an interesting advancement nonetheless and decided to share these tidbits of info today; cheers!
