Solvay process - The Full Wiki

Sodium carbonate can be mined from this source less expensively than it can be produced by the Solvay process, and with the closing of the original Solvay, New York plant in 1986, there have been no Solvay-based plants operating in North America. Throughout the rest of the world, however, the Solvay process remains the major source of soda ash.

Sodium carbonate - Wikipedia

The Solvay process recycles its ammonia. It consumes only brine and limestone, and calcium chloride is its only waste product. The process is substantially more economical than the Leblanc process, which generates two waste products, calcium sulfide and hydrogen chloride.
