- ggm 6y agoThe article also suggests using waste from steel and cement manufacturing, which is crazy. <citation required> If the production process is happening anyway, and if the waste exists anyway, why is it definedly crazy to re-purpose it? It isn't neccessarily the best at scale economic source of the kinds of rock dust we need, but if you have it, and it worked, then (without citing specifics like cross contamination risks or at scale problems) why is this specifically more crazy than the idea itself?
- linuxftw 6y agoPutting industrial waste onto food, bad, bad idea. Look into the amount of contaminants in former steel mill sites.
