With 35% CO2 in the flue gas of glass furnace as raw material, the liquid CO2 with a purity of 99.99% is produced through flue gas treatment, CO2 capture, compression, rectification and liquefaction, and the product quality reaches the national food level standard. The formal launch of the project will help CNBM to build a full life cycle "building materials+" integrated green industrial chain, and contribute to building materials for the country to achieve the strategic goal of "carbon neutrality".
