University students from the Pacific Northwest on Thursday competed in the Alaska Airlines Environmental Innovation Challenge in Seattle, pitching their best ideas for potential startups that could help protect the planet.

Twenty-two teams reached the finals of the annual event, hosted by the University of Washington’s Buerk Center for Entrepreneurship. Winning teams brought home prizes of $2,500 to $15,000.

Students incorporated technologies using software, drones, chemistry, engineering biology and other disciplines into their innovations.

Eric Carlson, a judge and member of the E8 venture capital group, congratulated the students’ hard work as he presented a prize focused on climate impact.

“A huge amount of work lies ahead to address the world’s environmental challenges,” he said, “and this very energy and commitment will be absolutely necessary to overcome these challenges.”

Makoto Hamamoto Eyre, who participated in the Environmental Innovation Challenge in 2020 and is now CEO and co-founder of Homeostasis, a carbon capture startup, provided words of encouragement and wisdom to the students.

“It’s a meandering path. And so long as you’re rigorous about it and open to pivoting and really diving deep, you’re doing the right thing,” Eyre said. “You’re gonna get punched in the face so many times, it’s crazy. But that’s part of the pathway. You’re doing the right thing.”
