Turning Roads into Carbon Sinks with Carbon Crusher

Haakon Brunell is the CEO and Co-founder of Carbon Crusher, a Norwegian company turning traditional road construction on its head. Carbon Crusher refurbishes existing roads using bio-based binders and on-site recycling to create carbon-negative, cost-effective, and more durable infrastructure. 

In this episode, Haakon shares how their "Crushing-as-a-Service" model and SkyRoads AI platform reduce emissions, increase road longevity, and drive down costs. He explains why roads are both a climate problem and a climate opportunity—and how Carbon Crusher plans to sequester a gigaton of CO₂ by 2035.

MCJ is an investor in Carbon Crusher, having participated in the company's seed round back in 2022 when it emerged from Y Combinator. Guest hosting for the first time on this episode is MCJ Partner, Thai Nguyen.
