Our own Bob Wimmer, Project Director of Infrastructure Solutions, joined the 4th grade students at Ebb Valley Elementary School in Manchester, Maryland, as part of the STEM program to see what an engineer does every day. Bob showed how spoiled food and other food waste can be converted into renewable natural gas through anaerobic digestion. The students learned how renewable fuels and converting waste into energy can provide additional options for producing energy. The students asked great questions about what an engineer does every day and Bob showed how engineering applies math, science, social skills and many other disciplines in order to construct new facilities and structures.
