In a world first, engineers from Britain's University of Cambridge have shown that cement can be recycled without the same steep cost to the environment as making it from scratch
Researchers on Wednesday said they were a step closer to solving one of the trickiest problems in tackling climate change -- how to keep making cement despite its enormous carbon footprint.
In a world first, engineers from Britain's University of Cambridge have shown that cement can be recycled without the same steep cost to the environment as making it from scratch.
Cement binds concrete together but the whitish powder is highly carbon-intensive to produce, with the sector generating more than triple the emissions of global air travel.
