BRUSSELS, June 4 (Reuters) - Belgian drugs, chemicals and plastics maker Solvay (SOLB.BR) said on Thursday that its Solvay Indupa INU.BA unit had completed the upgrade and expansion of its vinyl activities in Brazil.
The three-year, $150 million investment has left the Santo Andre plant with a total annual vinyl chloride monomer and polyvinyl chloride capacity of 300,000 metric tonnes per year, Solvay said.
The investment also included a new unit of chlorine and caustic soda production, which cut electric energy consumption by 30 percent and increased caustic soda production capacity to 170,000 tonnes per year.
Buenos Aires-based Solvay Indupa is 69.9 percent owned by Solvay and is listed on the Buenos Aires stock market. (Editing by Will Waterman)
