Carbon Capture and Utilization in Construction - Carbon Sequestration in Building Materials:

Introduction to Carbon Capture and Utilization (CCU): Carbon Capture and Utilization (CCU) in construction is a progressive strategy aimed at mitigating carbon dioxide (CO2) emissions from building activities. This approach involves capturing CO2 emissions and integrating them into various construction processes, with a focus on carbon sequestration in building materials. The goal is to reduce the overall carbon footprint of the construction industry and contribute to sustainable development.

Carbon Sequestration Techniques: Carbon sequestration in building materials involves innovative techniques to capture and utilize CO2. Certain building materials, like concrete, inherently absorb CO2 during their production. Additionally, emerging technologies explore direct air capture (DAC) methods, where CO2 is captured from the atmosphere and integrated into building materials during their manufacturing. These materials act as carbon sinks, effectively sequestering CO2 and minimizing its release into the environment.

Environmental Benefits and Challenges: The incorporation of carbon sequestration in building materials offers notable environmental benefits. It aids in combatting climate change by actively reducing the concentration of CO2 in the atmosphere. Furthermore, such materials often exhibit improved durability, thermal performance, and fire resistance. However, challenges persist, including the need for scalable and energy-efficient carbon capture technologies, addressing the economic viability of large-scale implementation, and encouraging widespread industry adoption for significant environmental impact.
