What to do with the Sulfur?

Its amazing what you can talk about when you are trying to avoid work. A group of us got on the subject of power plants and how to make them better for the environment. We came up with a pretty good idea. For a coal plant, the two main pollutants are sulfur and carbon-dioxide. There is a process where you use the excess steam to create cooled water. Run that water into a pool and use it to cool the carbon-dioxide. From there you then dissipate the CO2 through a coiled pipe running through the ground in either a forest surrounding the plant or a series of farms surrounding the plant using an osmosis membrane. The extra CO2 will be absorbed by the plants and infuse the air with oxygen.

The only problem we have found is what to do with the sulfur. If you mix it with something, it tends to create a nasty by product. Someone else talked about using an interior plant ring as a sulfur absorber and just replace the plants as they die off. I'm not sure that would be cost effective given how much sulfur you might be pumping out. Once you can figure out what to do with the sulfur, you could do a lot in regard to cleaning up power plants around the world and increasing either food supply or general plant growth. Either option is good.
