#32How are you saying this is carbon negative? Don't get me wrong the process is impressive and very cool, but the marketing around it just feels scammy.
-5kg of carbon per m2? How? The lignin based binder absorbs more carbon from the air after it is placed into the road? I may be misreading but it seems like these numbers are based on the amount of carbon in the lignin itself (i.e. since it isn't burned which would be positive, you can count it as negative as it is not burned)
If I am wrong on this, please correct me. But it sure sounds like a lot of conveniently vague statements to make for nice sounding numbers. This would be a shame as even without misleading claims of CO2 reduction, the benefit of removing oil from the process and replacing it with a renewable source is clear and should stand for itself.
If the binder does indeed absorb C02 over time what is the rate? What effect does it have on the binders stability? Or if its used in its manufacturing how are you sourcing the CO2? What is the breakdown timeframe for the binder releasing any sequestered carbon back into the atmosphere?

OP says the lignin is "a waste product from the paper industry" and "majority of lignin is burnt". So it sounds like: currently, grow tree (pulling carbon from the atmosphere), process for paper industry, burn the resulting lignin, carbon returns to atmosphere. With this process: grow tree, process for paper industry, embed lignin in road material. If the lignin remains in the road more-or-less permanently (I asked about this in a separate comment), that sounds like legit removal; the carbon started out in the air and ends up in the road.

#34Tangential question: Has there been a discussion already on why HN participants cant invest in such YC startups?
There's no restrictions on investing in YC startups if you participate on HN.
And we have emails and other contact options on our website if you would like to reach out, https://www.carboncrusher.io/

Yes exactly, that's how we think about it. We are using nature's own capture machine, trees... thanks for this clear explanation :)

#36I love this idea. I really hope your technology is more widely adopted.

#37Awesome, impactful concept, this can be huge! Now comes the challenge of scaling
Re: Launch HN: Carbon Crusher (YC W22) – Carbon Negative Roads
#38Very cool stuff. How far are you along with "SkyRoads"? Monitoring roads with the spatial resolution you would need sounds quite expensive. Though if it is for quotes on a per-request biases or once a year it might be more suitable.
