Cement & Concrete in the circular economy
Cement & Concrete plays an important role in the circular economy – utilising materials that would otherwise go to waste.
Concrete is recyclable[1] and Concrete buildings due to their inherent strength and durability can be repurposed, reused or recycled into useful new applications.
The cement and concrete industry is also a significant user of industrial by-products to replace Portland Cement as a binder in concrete, and the use of recycled aggregates by our industry reduces demand for natural resources.
In cement production, combustible waste materials including spent oils, rubber, plastics, wood waste and municipal garbage can be used as an energy source in the kiln as a substitute of fossil fuels. These fuel substitutes reduce the industry's carbon footprint[2].
