I guess that's the classic problem where waste is often economical to use as an input -- until the producer/market realizes it has an economic value and gets sold as a commodity.

If they want fly ash they are going to have to compete like everyone else in the cement/concrete business.

Usable flyash that isn’t complete shit is more and more difficult to come by and they might have to start looking at some of the dirtier stuff.

Also, they show any compression data on their products vs normal blocks?

I believe they have ASTM testing done on the blocks and are comparable to regular Portland blocks
