How recycling concrete could accelerate sustainable …
With the world's population still growing, so continues the development of humans' physical environment. As things stand we still rely on newly cast concrete as an efficient, strong and relatively low cost building material, emitting unsustainable amounts of CO 2 as a result (reckoned to be 4 billion tonnes of cement annually, equating to 8% of global emissions).
