When thousands of students gather on Libe Slope for Slope Day, the focus is typically on music, sunshine, and celebration. Behind the scenes, however, Slope Day has steadily become a model for how large campus events can reduce waste and support the Cornell community.

This year marked the fourth consecutive Slope Day with staffed waste stations, an initiative that began as a pilot effort and has grown into a cornerstone of the event’s sustainability strategy. Since that first year, Slope Day has seen measurable improvements in waste reduction and recycling accuracy every single year, demonstrating how small operational changes can add up to meaningful impact.

Waste Stations That Work

Waste stations—clearly labeled and staffed by trained volunteers—help attendees sort compost, recycling, and landfill waste correctly. The presence of people at each station makes a significant difference: questions can be answered in real time, contamination is reduced, and recyclable or compostable materials are far more likely to end up in the right stream.

Each year since implementation, waste diversion rates at Slope Day have improved, showing a growing culture of participation and awareness among students, staff, and visitors. What began as a new concept has now become an expected and effective part of the event experience.

Supporting Cornell Employees Through Bottle Deposits

Slope Day’s sustainability efforts now extend beyond waste reduction alone. Bottle deposit funds collected during the event are directed to Cornell’s Employee Emergency CARE Fund, turning returned containers into direct support for employees facing unexpected financial hardships.

This connection between recycling and community care highlights how sustainability can intersect with social responsibility—ensuring that the benefits of a large celebration extend well beyond a single day on the slope.

Community Cleanup Effort on the Slope

Once the music ends and the crowds disperse, another critical sustainability contribution begins. Members of CRU (Christian Reformed University Fellowship) volunteer their time to walk Libe Slope after the event, collecting remaining recyclables and waste to ensure materials are properly sorted and the space is left clean.

Their dedication plays a vital role in capturing resources that might otherwise be missed and demonstrates the power of student-led action in supporting campus sustainability goals.

Celebrating Progress—and Looking Ahead

After four years, Slope Day’s sustainability story is one of continuous improvement, collaboration, and shared responsibility. From staffed waste stations to employee support through bottle deposits and volunteer-led cleanup efforts, the event shows what’s possible when planning aligns environmental stewardship with community values.

As Slope Day continues to evolve, these efforts provide a strong foundation for making future celebrations even more sustainable—proving that Cornell traditions can grow while staying true to principles of care for people and the planet.
