In terms of recycling, precast concrete products can be crushed to form recycled aggregate and used in a number of applications. It is estimated that 90% of concrete products are currently either reused or recycled11.

Is steel a sustainable material?

Steel’s material properties make it the ultimate sustainable construction material both in terms of its material properties and the credentials of steel-framed buildings. … Low and zero carbon buildings and buildings with high BREEAM ratings are readily achievable using steel construction.

Why is concrete environmentally unfriendly?

The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil.
