How much is the use of lignin a factor, in terms of long-term scaling?
Your success will depend on some claims you are making. I really hope you are just brief here, and have it amply written up elsewhere with real data. It always a major let-down when I meet with the inventors/idea folks and I find out there is a lot of hand-waving about claims, facts, and data. Good luck!
Very cool project! In the attached video, was that crushing only or was lignin binder being mixed in as well? The output looks dark but kind of powdery, I would guess that's soil being mixed in, because I don't see a fluid tank on the back of that tractor. It looks like resulting the particle size is quite small - I would assume that some amount of aggregate would be tolerable or even beneficial for material strength…

1. Great question! Different academic experts claim lignin would be very stable in roads and stay there for a long time, and that when some degradation eventually happens, it will sequester downwards and become part of the soil. Deepdive: We have made roads 14 years ago which are still stable and in good quality today, indicating there hasn't been much degradation of the lignin to speak of. Adding here also a quote f…
Where is the road made 14 years ago? Does lignin resist fungus/bacteria in a hot humid place like Brazil?
How do you propose to deal with fungi/ bacteria which have no issue digesting lignin? Likewise, what would your source of lignin material? How do the transportation and processing costs impact your ability to generate the parent materials for this process?
And most rot is actually around the lignin. Amazing material.
What is the cost comparison per foot of road between traditional road repair and your approach (factoring in the maintenance interval increase)? Are there any regulatory challenges you've discovered that might be roadblocks to you scaling out? For example, Google Fiber had pole access issues due to regulations passed to benefit existing ISPs. Is there anything like this in this space?
Are there any niches where you see particular traction as being easier? You've got a big opportunity you're going after so I'm curious about where you're starting. For example, maybe you're especially attractive in adverse environments like snow + mountains. Or maybe cost-conscious towns where you can easily partner with local road repair crews and there aren't meaningful revenues for larger established players. Not actually sure, just curious where your land & expand strategy starts.

Why is "proprietary" important ?
This sounds like an incredible project -- and very much needed. Road building is such a huge source of emissions. What are the biggest objections that your customers tend to have? How much is the use of lignin a factor, in terms of long-term scaling?
There are huge amounts of lignin in the world which is the base for our current binder. With our current producer volumes and without leveraging synthetic bio we can reach USD 2bn in yearly global revenue. If we were to leverage all the current lignin supply in the world we could Carbon Crush 1.5million miles of roads every year.

290 million years ago, Agaricomycetes fungi evolved the ability to breakdown lignin. That is the only time any species evolved this ability. And most rot is actually around the lignin. Amazing material.
We are working working with some awesome scientists at https://www.nmbu.no/en and we will dig deeper into global fungi tactics together with them
