arbon Crusher was founded by Haakon Brunell and Kristoffer Roil in 2021, who were later joined by Hans Arne Flato. Together, they developed the equipment and technology for sustainable roads. The Carbon Crusher machine can crush asphalt and rocks finely.Instead of bringing new, costly materials, this machine grinds up the top layer of the existing road that needs repairs, recycling it. Then, instead of the conventional bitumen (a form of crude oil), it uses lignin, a natural component of plants, to glue the crushed top layer.Because the trees that are the lignin source absorbed CO2 throughout their lifetime, the end result of this road repair process is considered to be carbon-neutral. The lignin-based binder is said to be more flexible than bitumen, which makes roads last longer, without the potential cracking due to cold temperatures.
