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

Yes, thanks for clarifying
Another curious question: Do you make an "actual" limestone, or what is the final output? A rock, chalk, mudlike or something?
