Concrete is one of the world's most popular construction materials, noted for its strength, durability, and adaptability. However, its manufacture has major environmental consequences, including resource depletion and carbon emissions. As the globe moves towards more sustainability, including circular economy ideas into concrete manufacturing appears to be a feasible option.

The circular economy emphasises waste reduction and resource efficiency by extending the useful life of resources and products. This idea, when applied to concrete, entails recycling waste materials and using novel approaches to extend the life of structures.

One important feature of concrete manufacturing is the utilisation of recycled resources such as crushed concrete and construction and demolition waste (CDW). Incorporating these materials decreases the need to extract virgin resources, saves energy, and diverts waste from landfills.


Moreover, technologies such as carbon capture and utilisation (CCU) may absorb carbon dioxide emissions from industrial operations and use them in concrete production, improving the environmental performance.

Furthermore, maintaining, repairing, and refurbishing concrete buildings is critical for extending their life. Implementing modern monitoring systems and using durable materials can reduce the need for replacements, lowering resource consumption and waste creation.

The use of circular economy ideas in concrete manufacturing not only increases environmental sustainability, but also has economic benefits. It decreases reliance on raw resources, lowers disposal costs, and opens prospects for new business models and employment development.


Finally, including the circular economy into concrete manufacturing offers a viable avenue to achieve sustainability goals in the building sector. By focusing on resource efficiency, waste reduction, and durability, we can create a more resilient and ecologically friendly constructed environment for future generations.
