Adele Peters of Fast Company reports on Carbon Crusher, a Norwegian startup that is creating carbon-negative roads.
- The company uses a plant-based binder, instead of an oil-based one, and recycled asphalt to create carbon-negative roads.
- For now Carbon Crusher is focusing on replacing current roads with its unique technology, not building new ones.
- Free market innovation is key to creating a cleaner future.
“The process starts with recycling. Instead of trucking in new materials when a damaged stretch of asphalt needs repair, the company uses a machine that grinds up the top layer of the existing road. The equipment can also be used with concrete, another high-carbon material, as long as the concrete isn’t reinforced with steel. Then, the company uses lignin—a material in plants that’s a major byproduct of the paper industry—to glue the crushed material together.”
