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.

The invention is directed towards a process for complete conversion of multiple industrial wastes to sustainable alternatives and usable products resulting in water in-soluble product alike chemical gypsum useful for cement manufacturing used in construction industry. The inventor has utilized industrial wastes from multiple industries together taking into consideration their chemical and physical properties without using any form of energy. The whole process is carried out at ambient temperature under open sky. In described two exemplary processes, the inventor has disclosed process comprising the steps of mechanically mixing metallurgical inert waste of aged dry Jarofix containing crystallized Gypsum with freshly generated Jarosite or dry/wet Red Mud followed by addition of adequate acidic concentration waste water, calcitic wastes, pozzolanic property enhancers & lime treatment. The multiple wastes mix crystallized chemical gypsum mass on drying is used as a whole without any leftover.

A method of pumping a fluid and reactive solid into a mineral formation includes the fluid reacting with the mineral formation to produce a nucleation product. The method may be used in shale formations to seal fissures and prevent leakage. The fluid used in this method may comprise CO.sub.2 and the nucleation products may be the products of carbonation reactions. A cement formed by reacting CO.sub.2 with a reactive solid under deep geological formation conditions is also disclosed.
