Document Type and Number:
WIPO Patent Application WO/2023/219458
Kind Code:
A1
Abstract:
The present invention relates to a method of reducing carbon dioxide using microalgae. The carbon dioxide reduction method according to the present invention comprises the steps of: supplying carbon dioxide (CO2)to a first medium within a reactor to produce bicarbonate ions (HCO3 -); inoculating microalgae into the first medium supplied with carbon dioxide and performing a first phototrophic cultivation; adding calcium ions (Ca2 +) to the first medium inoculated with microalgae and performing a second phototrophic cultivation, so as to produce calcium carbonate (CaCO3); and discharging a portion of the first medium from the reactor and adding a second medium to the reactor to perform a semi-continuous cultivation process.
