Penrice is the only manufacturer of soda ash and sodium bicarbonate in Australia and in 2004 supplied 74% of the soda ash and 88% of sodium bicarbonate used by Australian industry.

Soda ash is predominantly sold into the Australian market for use in the manufacture of glass containers (typically wine bottles) and flat glass. Sodium bicarbonate is sold domestically as well as exported with major end uses including animal feed, food, kidney dialysis, personal care and pharmaceutical products.

Penrice also operates the largest marble and limestone mine in South Australia at Angaston in the Barossa Valley. The Mine provides a secure low cost input into the production by Penrice of soda ash and sodium bicarbonate. External sales from the Mine are used for a variety of applications including cement, civil construction, lime, glass, mineral processing, agriculture, stockfeed and landscaping.

Penrice's total sales revenue for the year ending 30 June 2006 is forecast to be from 71% soda ash, 18% sodium bicarbonates and 11% limestone.
