Norwegian startup is building carbon-negative roads.

Carbon Crusher combines recycled asphalt with plant-based glue to repair the blacktop instead of using traditional bitumen—a viscous form of petroleum that has a significant environmental impact and even continues to emit air pollution once in place on the road.
