This disclosure relates to a foamable resin composition containing a nitrogen gas-generating compound and methods of using the composition for loss circulation control.

A system and method for disposing carbon dioxide is disclosed. The system includes a foam generator that generates a plurality of disposable foam vessels from a polymer based solution mixed with water and captured carbon dioxide from the atmosphere. The plurality of disposable foam vessels contains an amount of carbon dioxide. The plurality of disposable foam vessels is mixed in a cementitious material with a set of mixers. In a preferred embodiment, the set of mixers is a concrete mixing plant. During the curing process of the cementitious material the plurality of disposable foam vessels dissipates allowing for a timely release of CO.sub.2 to chemically react with the surrounding cementitious material. This irreversible chemistry change permanently disposes of the carbon dioxide.

Systems and methods of sequestering carbon dioxide in concrete are described herein. The methods include combining water and a foaming agent to form a foaming agent mixture, adding a gas comprising carbon dioxide to the foaming agent mixture in a first mixing chamber, mixing the water, the gas comprising carbon dioxide and the foaming agent to form a foam mixture in the first mixing chamber, the foam mixture comprising a plurality of foam bubbles containing the at least a portion of the carbon dioxide, combining the foam mixture with concrete materials in a second mixing chamber so that the foam mixture contacts the concrete materials, the concrete materials comprising cement, and mixing the foam mixture and the concrete materials in the second mixing chamber to form the concrete having the carbon dioxide sequestered therein.
