City eyes biogas to fuel vehicles

By Joe Pinchot, The Herald

When Hermitage city officials were forced to upgrade the water pollution control plant, they decided to do it in a way that would save the city money along with benefiting the environment.

The saving money part was to come from cooking sludge and waste food to create a biogas that could be burned to generate electricity.

But, city officials are learning that, with the installation of new equipment, at a comparatively modest expense, they can save much more money.
