MECS is the global leader in sulfuric acid process technology and related high performance products custom engineered for acid plant production environments. These process technologies combined with value added technologies for ethanol production, heat exchange and specialized air pollution control form a diversified and strong business positioned for serving customers world wide. MECS has built long term relationships throughout the world using strategically positioned local offices, sales reps and agents, joint ventures, licensees and a respected and experienced global supply chain. The foundations of MECS were constructed and began with Monsanto Enviro-Chem Systems Inc. This original company was formed as a wholly owned subsidiary of Monsanto Company in 1969 through a consolidation of several existing process technology, product and services businesses. Some of these businesses were established as early as 1917. On August 5, 2005 the management team of Monsanto Enviro-Chem Systems, Inc. completed the purchase of the subsidiary from Monsanto. As a result, the new MECS Inc. is built on a heritage of nearly 100 years in assisting customers to achieve added value in their process operations.
