Method and Related Systems for Capturing Carbon Dioxide from Air

A method of capturing carbon dioxide and/or ammonia from biomass material, the method comprising:

• providing a capturing apparatus comprising a first chamber and a second chamber in open communication with one another such that air can be transmitted between the first chamber and the second chamber, wherein the first chamber and the second chamber collectively define an enclosed space from which said air cannot escape;
• placing the biomass material in the second chamber and allowing the biomass material to decompose in the second chamber whereby said air within the enclosed space is enriched with carbon dioxide and ammonia;
• providing a source of water enriched with hydroxides in the first chamber such that carbon dioxide in solution in the water is below equilibrium with carbon dioxide in the air within the enclosed space and the water absorbs some of the carbon dioxide in the air.
