Coal ash is currently being toted as an “green” additive to concrete. Just to clairify… Coal ash is considered hazardous if it is released into air or water, yet when added to concrete it is then rendered safe? Eventually, it would be re-released into the environment when the concrete is removed and ground into gravel again. More on this topic to come.
