Ecolab and Badger State Ethanol:

Providing the Value of a Total Cleaning Partnership

Ecolab has a long-standing business model of “finding a customer need and filling it.” Three years ago, when Ecolab was looking for new ways to fuel continued growth, the Ecolab team began looking at other market segments that used CIP processes; a cleaning technology Ecolab invented more than 50 years ago.
