To lower greenhouse gas emissions, the construction industry uses carbon dioxide sequestration, which is the process of capturing and storing carbon dioxide. In an effort to lessen its environmental impact, the construction sector, which produces substantial amounts of carbon dioxide through the manufacturing of steel and cement, is turning increasingly to carbon dioxide sequestration technologies. Here are some important techniques and developments in carbon dioxide sequestration for the building industry:
1. Carbon Capture and Storage (CCS)
Capturing carbon dioxide emissions at the source is a key component of CCS, moving it to a storage location, and seeding geological formations beneath the surface. By keeping carbon dioxide out of the atmosphere, this technique greatly aids in the effort to reduce emissions.
2. Carbon Capture and Utilization (CCU)
The goal of CCU is to capture CO2 and use it to make products that are beneficial to society, incorporating it into the value chain. Concrete, aggregates, and even polymers are among the building materials that can be made with the help of carbon dioxide.
3. Bio-based Materials
Hempcrete and mycelium-based composites are two examples of bio-based building materials that naturally sequester carbon dioxide as they grow. These renewable resources serve as carbon sinks and offer an eco-friendly substitute for conventional building materials.
4. Enhanced Weathering
Spreading finely ground silicate rocks over construction sites promotes enhanced weathering. By reacting with atmospheric carbon dioxide, these rocks effectively sequester carbon by forming stable carbonate minerals. This technique can be included into efforts to stabilize the soil and landscape during building projects.
5. Direct Air Capture (DAC)
Although not specifically related to construction sector, DAC technology can be utilized in conjunction with construction projects since it directly extracts carbon dioxide from the air. The carbon dioxide that is captured can be stored underground or used to produce building materials.
Challenges and Considerations:
Cost: The initial investment and ongoing expenses associated with carbon dioxide capture technologies can be substantial. This is one of the challenges associated with implementing carbon dioxide sequestration in the construction industry.
Energy Requirements: If energy is not sourced sustainably, the energy requirements of some sequestration techniques may outweigh the benefits of reducing carbon dioxide emissions.
Scalability: One major challenge is scaling these technologies to meet the enormous demands of the construction industry. Support from Regulation and Policy: Incentives and regulations from the government are essential to encourage the use of carbon dioxide sequestration technologies.

A workable solution for the construction sector to lower its carbon footprint is carbon dioxide sequestration. The industry can change its methods to become more ecologically conscious and sustainable by utilizing cutting-edge materials and technologies. The incorporation of carbon dioxide sequestration techniques is anticipated to increase in popularity and become increasingly important in the worldwide fight against climate change as technology develops and costs come down.
