Cementos Portland Valderrivas said it plans to invest – US$180m to upgrade its cement plant at Bath in the state of Pennsylvania. The unit of construction group Fomento de Construcciones y Contratas (FCC) said the move will allow the factory to increase its output by 50 per cent with lower energy costs and less environmental pollution. The new project will bring Cementos Portland’s total investment in the United States to date to US$800m.
