Method and apparatus for carbon dioxide sequestration

A method for sequestering carbon dioxide, comprising:

• mixing a pre-mixture of primary fresh concrete ingredients in a rotatable mixing drum which is mounted to a chassis of a wheeled vehicle;
• operating an internal combustion engine so as to produce an exhaust gas containing products of combustion including carbon dioxide, wherein the internal combustion engine is configured to drive one or more wheels of the wheeled vehicle;
• cooling the exhaust gas, wherein the exhaust gas is cooled by passing it through a heat exchanger which is cooled by a cooling fluid having a temperature lower than a temperature of the exhaust gas;
• directing the cooled exhaust gas into the mixing drum;
• introducing the exhaust gas into the pre-mixture of primary fresh concrete ingredients during the mixing process;
• and
• allowing the carbon dioxide from the exhaust gas to be physically mixed with and sequestered into a fresh concrete mixture.
