Limestone Makes for Cleaner Coal.C&E Concretesaw 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.

An SO2 scrubber systemis the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas. There are some variations in design of scrubbers.
