Airports throughout the United States are greening their operations. They are installing solar panels and energy efficient light fixtures, using low-emission vehicles in their fleets and changing their waste management programs. The Environmental Protection Agency (EPA) designed this guide to help airport managers who want to create a more environmentally-friendly waste operation. The EPA hierarchy of waste management prioritizes source reduction, then reuse, recycling and finally disposal in landfills. However, this guide focuses on recycling as a positive first step for airports to take as they conquer their waste issues.
