A global leader in Soda Ash
Solvay is a global leader in Soda Solvay® sodium carbonate production, using two different processes: the traditional Solvay ammonia process and the refining of a primary source of sodium carbonate, natural Trona (or sesquicarbonate).
e.Solvay: the new Soda Ash Process
Solvay has invested €40 million over the past years to develop proprietary technology first patented in 2014. Solvay’s researchers and engineers have invented e.Solvay, a new method to produce soda ash, achieving three revolutionary improvements in the process: emitting 50 percent less CO2; reducing water, brine and limestone consumption; and completely eliminating limestone residues. This should allow Solvay plants to operate more efficiently and sustainably, while enhancing their competitiveness.
