Secrets of Sustainability at SEA
By Isabella Newcomer, Environment and Sustainability Intern.
When I tell people that I have a summer internship with the Port of Seattle’s Environment and Sustainability Department at Seattle-Tacoma International Airport (SEA), their initial reactions are often confusion, or even disbelief that a major airport has a whole department focused on environmental stewardship. My time with the Port of Seattle supporting waste reduction and outreach programs has not only given me my first professional experience in my chosen field of study (I’m a rising junior at Scripps College studying Environmental Analysis) but also a unique lens into the behind-the-scenes operations of an airport. If you’re anything like me, you’ve looked out the window at your gate while waiting to board a flight and wondered, “What is that pipe for? What does that button do? Where do my bags go after I drop them off at that scary-looking conveyer belt?"
