A paper towel in a public washroom? It’s made from recycled paper. Pick up a coffee from your local drive-through? The cup is made from recycled plastic.

Concrete is the most commonly used construction material in the world, but it is also the biggest in terms of environmental impact, says Yahya "Gino" Kurama, a professor of civil and environmental engineering and earth sciences at Notre Dame.
