Sustainably manufacturing glass through soda ash]
20211117Soda ash is a vital component in glass, as it reduces the melting temperature of sand, the primary ingredient used in glass formulation, significantly cutting down energy use and related CO 2 emissions. As a result, glass manufacturing accounts for over 50% of the total soda ash production.

Lime in the Production of Soda Ash
By increasing the lime dosage, either the trona or soda ash can be converted to caustic soda, a higher-value product. In this process, lime is first slaked and converted to calcium hydroxide (Ca (OH) 2 ). Next, the lime slurry is combined with soda ash (Ca (OH) 2) + Na 2 CO 3 ). This yields caustic soda and limestone (2NaOH + CaCO 3 ).
