How to reproduce NaHCO3 by using Sodium Sulphate?

This is the solvay process to make sodiumcarbonate from sodiumchloride basically. Nothing to do with Sulphurdioxide.

No i meant: can we use solvay process to produce sodiumbicarbonate from Na2SO4 + Ca(HCO3)2 ?
The Na2SO4 generating by the filter as a waste. So we may add Ca(HCO3)2 into it and for an industrial scale , we may use solvay process for doing this?

chenbeier:
Probably, but a problem would be at step 7, what will happen there? Convert that diagramm from NaCl to Na2SO4, what other chemicals will go arround, what are the soloubilities in comparison of the existing process?
