Braskem S.A.
General Manager (1976-2006)
Braskem S.A. was the first company in S. America to produce salt by solution mining and to use abandoned salt cavities for waste disposal (calcium/magnesium slurry resulting from brine treatment).  Braskem started operations in 1975 and has since produced more than 20 million tons of net salt (sodium chloride) via solution mining.  800,000 ton/year brine production for chlor-alkali plants located in Alagoas and Bahia.
