Michigan is known as the Great Lakes State since it borders on four of the five Great Lakes. Much of the state's economy is dependent at least in part on the supply of water from the lakes either to feed industry or tourism. For years that has been concern in the state about large scale bottlers taking the water from the lakes to package and sell at inflated prices. This has been a particular concern in recent years with dropping lake water levels.
The Poland Springs unit of the Nestle company has announced that they are switching over their entire water tanker fleet to running on B5 biodiesel. The company expects the change to yield reductions in carbon dioxide emissions of 1.8 million pounds per year. Poland Spring's use of biodiesel is part of their company wide effort to reduce their environmental footprint that includes a 91 percent internal recycling rate.
