Campus Wide Zero Waste Data
>Back to Sustainability Initiative Homepage
This webpage hosts our Zero Waste Calculator, depicting the current state of our campus zero waste journey. There are several displays of data in the window below, containing actual weights of the waste generated across campus. Most of the waste data is broken up by building, allowing campus community members to better understand waste in their particular sphere of influence. Please note the sheets at the bottom of the window, containing four different views of campus waste data. These charts and tables are updated weekly, so come back each week to check in on our progress as a campus!
- Table: This sheet contains a snapshot of our campus-wide waste generation for the most current week and the week preceding it. Shown is each building's waste mix for the two most current weeks (including pounds of recycling, compost, and trash) along with its total waste generated and diversion rate for that week only. (This is a change from previous years, when all diversion rates were listed as cumulative values.)
- Weekly Charts: The graphs show the two most recent week's waste data for each building on campus. The buildings are grouped together in categories based on building use. A few important notes: The waste data are all listed in pounds and the graphs in each category (i.e. classrooms) are using slightly different scales.
- Trend Lines: This sheet shows each building's weekly diversion rate throughout the year in a graphic display, allowing users to quickly see a building’s journey to zero waste! As you can tell from the graphs, the journey to a zero waste campus does not happen overnight. The path is not always straight or predictable, and it is filled with highs and lows. To see a specific building's diversion rate for a certain week, simply hover over the point on the colored line of the building which you are seeking.
- Diversion Rates: This sheet shows each building's weekly diversion rate throughout the year as in the “Trend Lines” sheet, but in a numerical display.
Terms
Waste Mix: This refers to the types of waste streams leaving a building. Generally, waste mix is composed of compost, recycling, and trash.
Diversion Rate: Refers to the percentage of waste generated that was not sent to the landfill/incinerator. Waste diversion rate is calculated by: The sum of recycling & composting divided by the sum of the total waste
Cumulative Diversion Rate: The total percentage of waste generated on campus throughout the year that was not sent to the landfill/incinerator, beginning on July 1.
