Sustainability: Protecting and Preserving our Resources.

The William Charles organization was committed to preserving and protecting the environment long before it was
considered the right thing to do.

William Charles is looked to as the state model for fostering the green movement with our landfill gas-to-energy
technology. We constructed a gas-to-energy plant at Winnebago Landfill that generates enough electricity to power 10 percent of the homes in the City of Rockford. From using reclaimed oil to heat buildings and fire asphalt plants, to building and maintaining hundreds of acres of wetlands and open spaces, we are engaged in a wide variety of green activities.

As we move into the future, the William Charles organization continues to embrace our role of good stewardship
throughout our Construction Management, Waste and Environmental Services and Real Estate Development
business units.

We use recapped tires; recycle vehicle and equipment filters; and annually recycle approximately 50,000 tons of
asphalt, saving approximately 2,400 gallons of oil. We have converted dozens of commercial and industrial brown
fields into productive reuse. And we continue to actively explore new sustainable energy technologies on the horizon, such as geothermal energy, solar energy, wind energy and gasification.

William Charles is LEED certified by the Green Building Council for Leadership in Energy and Environmental Design.

The William Charles quest to convert to alternative-fuel
William Charles operates a compost facility that receives approximately 26,000 tons of yard waste in a season. After processing, it is sold the following year as finished compost to golf courses and other landscapers. Throughout the William Charles companies, a total of 200,000 gallons of biodiesel is used during the year. With time, we hope to completely convert to alternative-fuel.
