Sustainability wins worth celebrating

CU �Ǹ�Թ�’s commitment to sustainability took a major step forward this year as the�� celebrated its first full year of operation—and the numbers show just how much progress the campus has made in waste diversion and reuse.

Opened in January 2025, the Surplus Store was created to give university-owned items a second life while offering affordable options for students, faculty, staff and the community. From clothing and office furniture to electronics and lab equipment, the store has quickly become a resource for those looking to save money, reduce waste and participate in a more circular campus economy.

A year of measurable impact

In its first full year, the Surplus Store saw dramatic growth in both the volume of items redistributed and the materials diverted from the landfill. Compared to the year prior to its soft opening, the number of items moved through direct sales, campus sales and donations increased by��311%—jumping from 3,427 items to 14,086. Total material tonnage diverted from disposal also rose sharply, growing by��262%, from 115.49 tons to 418.6 tons.

To put this impact into perspective, CU �Ǹ�Թ� generates nearly 5,000 tons of waste each year, diverting about half through recycling, composting and reuse. The Surplus Store plays a major role in that effort, helping to manage materials that make up nearly 10% of the campus’s total diversion by mass and 20% of the university’s overall waste‑diversion impact. And because reuse gives material a useful second life, it delivers on our goal to build a circular economy for our campus and the region.

“These results show what’s possible when we make sustainability simple and accessible,” said Walter O’Toole, assistant director of Distribution Services. “Every item reused saves resources and supports our campus community.”

“The Surplus Store is a great example of how CU �Ǹ�Թ�’s campus serves as a living laboratory for sustainability, turning everyday actions into meaningful impact,” said Andrew Mayock, CU �Ǹ�Թ�’s vice chancellor for sustainability. “By extending the life of university materials, we reduce waste, lower our environmental footprint and strengthen our culture of reuse. This progress moves our campus toward a more sustainable future and offers a model for other campuses and communities.”

Circularity in action—at an accessible price

Beyond reducing waste, the Surplus Store also supports equity and affordability on campus. By reselling high-quality items at low cost—including sit-stand desks, Windows-11-ready laptops, dorm essentials and clothing—the store makes essential resources more accessible for both students and community members.

This model of reuse is central to CU �Ǹ�Թ�’s circularity efforts: keeping materials in use longer, reducing the need for new purchases and ensuring that valuable goods remain available within the campus community rather than ending up in the landfill.

Weekly walkthrough videos on the store’s website help shoppers preview what’s available before visiting in person.

“The growth we have seen is exciting because it shows people really want to participate in reuse,” said Denise Worthington, property services program manager. “Every item that finds a new home makes a difference.”
