Biostone: Biological Concrete made from 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: www.gizmag.com/dupe-sand-urine-bacteria-concrete-machine/30804/

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!
