Energy from food waste

There seems to be a minitrend that I hope is as good as it sounds. Some food companies are exploring ways to take the waste that's produced in the course of their manufacturing and convert it to energy.

A recent such announcement comes from the Philadelphia Cream Cheese division of Kraft. Two of their plants in upstate New York plan to convert the whey (a byproduct of cheesemaking) into biogas, thus reducing their gas energy purchases by about one-third.

Another food company looking for similar solutions is Heinz. At their production facility in Oregon, there are plans to produce biofuels from potato peels.

If they joined forces, they might also have a fine potato chowder.
