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.
According to the company, the over 40-million miles of roads worldwide emit approximately 400 million tons of CO2 per year through both construction and maintenance. One study, published in 2019, reported that each kilometer of road produced around 65.8 kilograms of CO2 equivalent.
In addition to being more sustainable than traditional methods, Carbon Crusher says that its process is faster, more cost-effective, and even sequesters carbon once implemented. The company also believes that its road surfaces are more durable than others.
