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.
Claims18
A method of manufacturing a living construction material, comprising:
- (a) loading a solid object with cells of a urease-producing organism and a urea-producing organism to produce a loaded solid object;
- (b) adding the loaded solid object to a marine environment, the marine environment containing one or more of carbon, nitrogen and calcium;
- and
- (c) forming 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 one or more of carbon, nitrogen and calcium, while the loaded solid object is in contact with the marine environment, to thereby produce the living construction material.
