   Thanks for the comment. See calculation breakdown added in a few threads above. Some of our thoughts about the carbon negative part: Paper mills captures CO2 from trees (that are sustainably harvested, more trees planted than harvested p.a.

   This is a very fair question. We need to be mindful going forward in how we communicate. We can say that our Scope 3 emissions are negative, but scope 1 we are slightly positive (but still much lower than competition) Just to clarify; we go

   It's correct that lignin is used as a fuel, here's one source of it. ~98 is burnt. "currently most of the lignin produced from paper industry is burned as low-value fuel to generate electricity and heat (Luo and Abu-Omar, 20

   Thank you for this Question! In Norway, where we have stabilized more than 2,5 mill sqm of road, this is the problem we solve the most. Our Lignin is very strong, and more dynamic than our competitors binders, which means it doesn't c

   Yes indeed, thanks for the great short hand product notes! Lower carbon impact + lower cost + 0-25% more durable We can supply the crusher hardware, our binders, onsite first time PM + remote PMs after that. We now do this in all of Europe,

   Thanks for the question! I do not believe that Lignin is the right "glue" in this case. It is quite water resistant, but to bind properly, it needs a certain amount of finer particles in the mix. If You choose gravel instead of p

   Thanks for diving into this! Yes, our Crusher, method and the Lignin binds sand and silts in a great way. If there is a lot of clay, we would also like to add some lime to help with the internal moist, here we have several carbon neutral so

   Thanks for digging into this, awesome questions! Transport is included in all of our estimates, but we haven't yet done the comparison for every location in the world. We are working on a tool so we can on the fly update the CO2 calcul

   Good question! First I think Haakon thinks it sounds A LOT cooler. Second, we have been R&D our asses off developing the actual Crusher hardware. The current Crusher we have developed over the last years is specifically designed for cr

    Thanks! We are very excited turning roads into a part of the climate solution. Road construction and refurbishment is a very conservative industry and unfortunately they often want to stick to the way they've done things before. But we

    "Great question, we would love to crush carbon in South America! Our 14 year old road is in Heart Valley in Norway. All of our experience is from Norway so far and our current binder works well in similiar climates around the globe. So

    Thank You! You are right! The video shows the first step, which is the crushing. Lignin mixing is step 2. The road can be used by cars immideatly after compacting, as with other methods. However, if You want asphalt on top, it is necessary

    Yes! We are the nice vikings, crushing carbon every day! :-)
