In the future, the cement and concrete industries will use a variety of carbon capture and utilization technologies to capture carbon dioxide emitted into the air during production, use, recycling, and upgrading, so as to completely realize a closed cycle of carbon dioxide.

At present, the cement industry is trying its best to reduce its carbon footprint and has controlled its carbon emissions to about 7% of the global total. However, in order to achieve the goal of zero net emissions, the cement industry must use carbon capture technology.

Currently, the cement industry is developing the following types of carbon capture technologies：
·Direct separation/non-contact calcination
·Oxygen-enriched combustion
·Capture after combustion
·Calcium cycle
·Amine method
·Ammonia method
·Membrane separation method

Although carbon capture technology continues to advance, there are still challenges in its economic considerations. Therefore, the establishment of a "carbon economy model" will help us no longer be limited to a few case studies, so as to widely deploy carbon capture technology. In the process of establishing this economic model, we need to re-evaluate carbon dioxide as a usable commodity, not waste.

At the same time, the construction industry has begun to work hard to establish a carbon dioxide economic model. Among them, concrete carbonization, which concrete engineers have worried about for a long time, is providing a series of opportunities for permanent storage of carbon dioxide in building materials.


The vision of the Low Emissions Intensity Lime And Cement Project is to achieve the future sustainable development of the cement and lime industry without significant impact on operability, capital intensity or efficiency.

In addition to the construction industry, there are some commercial technologies that can consume large amounts of carbon dioxide. Among them, in addition to the well-known use of enhancing oil recovery, other traditional uses of carbon dioxide include urea production, Sabazi synthesis, Fischer-Tropsch synthesis, hydrogenation to methanol, dry reforming, hydrogenation to formic acid, and Electrochemical reduction etc.

In addition, various industries are also actively developing and using biotechnology to complete carbon capture and utilization. Among them, the low-cost microalgae can not only effectively "eat" the carbon dioxide in the flue gas, but can also grow into algae, which can be further used in the production of bioplastics, biofuels, and fertilizers. For example, in applications in the cement industry, algae can be processed into fish food and provided to local fisheries.
