Cool. Yeah, maybe the old way of making cement will be too expensive in the future compared to a greener way. Good luck with your first mover attempt!
Another curious question: Do you make an "actual" limestone, or what is the final output? A rock, chalk, mudlike or something?

Thanks! Yeah, we think it will be. But more importantly, the old way isn't a viable option. It's effectively off the table. Sweden has already banned mining of limestone (https://www.ribaj.com/products/cementa-limestone-mine-suspen...) The product comes out as a really finely ground powder

to be specific, an application was not approved and the reason the court gave was insufficient proof that continued mining wouldn't effect the local groundwater

I think it's a bit late for foresight, maybe Cassandra (is there a Norse equivalent?) is a more apt description of the situation we are in ;-)
Good luck, great idea, hope it works out!

They're pretty good too ;)
Our experience so far has been that the environmental angle has been sufficient to persuade. Cement companies are in a bit of a bind given the attention to their sustainability efforts. However we're pitching ourselves as a cost competitive solution. Depending on geography we'll be able to positively affect their bottom line through the carbon credits system. Under the European ETS for example, they reward companies that reduce emissions (https://carbonmarketwatch.org/wp/wp-content/uploads/2016/11/...)
