Carbon Crusher has developed a process for repairing roads in a way that makes them carbon neutral

There are roughly 70 million kilometres of road worldwide. Most roads are made using oil-based bitumen to bind the small pieces of crushed materials together. Maintaining and repairing such an extensive network currently involves trucking in new materials to fill holes and cracks on heavy duty construction vehicles. All of this combines to make roads significant polluters.

By speeding up the repair process, and focusing exclusively on making roads smarter, more useful and sustainable, a long-overlooked resource could become an environmental asset, rather than a polluter. Methods for sequestering carbon are improving, providing growing numbers of opportunities to use new materials. And integrating infrastructure already in place into new systems of renewable energy networks, such as road-charging for EVs, could reduce costs while increasing accessibility, helping governments build momentum for take-up of new transport technologies.
