Waste Data

1. In 2020, the campus population declined due to the COVID-19 pandemic, leading to a significant increase in the tons of landfilled waste per person.

2. In 2025, categories were modified in order to more accuratly represent the material and its use. For example, Reduction and Reuse was introduced in 2025 to capture edible food leftovers, which was previously categoried under Organics. Additionally, Other Recovered Material was removed and the items were reclassified under Recyclables. Lastly, wood chips, logs, brush-to-chips, and grasscycling have been reclassifed from Organics to Reduction and Reuse because that material is repurposed to some areas on campus.
