What kinds of waste are produced by smokestack scrubbers?

    Cleaning the air comes with a cost.  Smokestack scrubbers remove sulfur from emissions using a shower of limestone.  The byproduct is a non-toxic material called gypsum that is recyclable.  Gypsum can be used in concrete as an additive.  The trouble is that there does not exist a market for the amount of gypsum that will be produced – more than 300,000 tons per year.  Landfills have to be created for the massive amounts of gypsum.
