C&E Concrete saw a window of opportunity in the 1980's to join the greener power generation. With the help from Volvo wheel loaders and articulated haulers they are able to contribute to the greener power movement by extracting limestone that is used by coal power plants to scrub exhaust emissions and for dust control in underground coal mines to prevent explosions.

What happens when lizenithne is fed in a coal-fired boiler ... Another by-product of Coal use, which we've touched on only once or twice, is the "sludge" generated by at least some types of "Flue Gas Desulphurization", "FGD", devices, which, by regulation, are now being installed on all new Coal-fired electric power plants, and which have been retrofitted on most existing ones.
In coal plants crushed limestone can be used as a filter to remove acid rain causing emissions before they can go up the stack.
