Abstract
The invention is directed to kits, compositions, tools and methods comprising a cyclic industrial process to form biocement. In particular, the invention is directed to materials and methods for decomposing calcium carbonate into calcium oxide and carbon dioxide at an elevated temperature, reacting calcium oxide with ammonium chloride to form calcium chloride, water, and ammonia gas; and reacting ammonia gas and carbon dioxide at high pressure to form urea and water, which are then utilized to form biocement. This cyclic process can be achieved by combining industrial processes with the resulting product as biocement. The process may involve retention of calcium carbonate currently utilized in the manufacture of Portland Cement.
Claims16
A living construction material comprising:
- a loaded solid object comprising cells of a urease-producing organism and cells of a urea-producing organism, wherein the loaded solid object is loaded with spores and vegetative cells of the urease-producing organism and the urea-producing organism via placement of a solid object in a composition containing dry organisms such that the organisms are retained within or on a surface of the solid object;
- and
- a carbon source, a nitrogen source and a calcium source,
- wherein the loaded solid object is configured to form calcium carbonate within, around, or external to the loaded solid object for a period of six months or more using the cells of the urease-producing organism and the urea-producing organism, and the carbon, nitrogen and calcium sources, while the loaded solid object is immersed entirely within a marine environment.
