Thanks to the boom in shale gas, the US chemical market in particular has been undergoing a renaissance since 2009. Over the past few years, annual chemical production in the Americas has risen by 3.6 percent on average. Investments have climbed 10 percent during the same period. The chemical industry on the other side of the Atlantic is dominated by two countries. The US chemical sector accounts for 90 percent of chemical sales in North America. The main player in South America is Brazil, which represents 51 percent of chemical sales there.
