Abstract
A method and a system of properly utilizing CO2 captured from the atmosphere as an agricultural fertilizer and a fuel for electric generation. The recycling method comprises: collecting information relating to demand for the CO2 to be utilized as the fertilizer and demand for the CO2 to be utilized as the fuel; calculating a ratio between an amount of the CO2 to be utilized as the fertilizer and an amount of the CO2 to be utilized as the fuel, based on the collected information; and thereafter utilizing the CO2 as the fertilizer and as the fuel based on the calculated ratio.
Claims4
A recycling method of utilizing CO2 captured from air as a fertilizer to supply nutrients to plants, and as a fuel to be burnt to generate thermal energy, comprising:
- collecting information relating to a demand for the CO2 to be utilized as the fertilizer and a demand for the CO2 to be utilized as the fuel;
- calculating a ratio between an amount of the CO2 to be utilized as the fertilizer and an amount of the CO2 to be utilized as the fuel based on the collected information;
- and
- thereafter utilizing the CO2 as the fertilizer and as the fuel based on the calculated ratio, wherein
- the ratio between the amount of the CO2 to be utilized as the fertilizer and the amount of the CO2 to be utilized as the fuel is calculated based on a demand for an electric power to be generated utilizing the fuel derived from the CO2.
