Concrete is the most manufactured and used material on the planet. With all its versatile applications in the building and construction industry, it has to a great extent shaped our modern societies. Worldwide, around 30 billion tonnes of concrete are produced each year.
However, the environmental footprint of this abundant material cannot be neglected. Concrete is basically composed of cement and aggregates, the former mainly acting as a binder for the latter. Currently estimated at 4 billion tonnes a year, the production of cement has a significant impact on the climate, and it is everywhere on the rise due to the increasing demand for concrete.
The huge carbon footprint of cement production accounts for approximately 8% of the world’s carbon dioxide (CO2) emissions. Considered one of the largest greenhouse gas emitters on the planet, the cement industry is actively searching for solutions to lower its carbon footprint and manufacture greener concrete products.
