Below is an email from Daphne regarding waste/energy tracking at Athletics.

Hi Jen,

Yes! I’m attaching the spreadsheet used to generate the graph, as well as the spreadsheets containing the raw data. I’m cc’ing Shreya in this conversation as she has contributed the most to visualizing the waste and recycling data.

For background: Looking at the raw data you will notice that it is separated between frontload and rolloff/swingpan – these are the 3 types of outdoor receptacles we use for landfill and recycling collection (frontload being smallest, swingpan being a little bigger, and rolloff being largest size). They are separated because their collection process is different. Then, we must bring all the data together for metrics like a diversion rate.

Frontload receptacles are lifted, and their contents are dumped into a truck. The frontload receptacle is left in place after, so trucks go around and pick up multiple buildings’ worth of frontload waste (like neighborhood trash trucks). For this reason, we don’t have a perfect understanding of how much waste individually comes from buildings with these receptacles (though the technology does exist for us to eventually understand this better).

Rolloff receptacles are rolled directly onto and off the truck. Some rolloffs have a compactor built within them (State Farm Center, for example). The receptacle is then taken to the Waste Transfer Station, weighed, dumped, and then taken back to its original location.

Swingpan receptacles function just the same as rolloff, the only difference is the smaller size of the receptacle.

I’m attaching a single slide that visualizes the receptacle and accompanying truck, as this is what helped bring it together for me. All three types of receptacles are used for both landfill and recycling collection, it’s just a matter of how much space is outside any given building for a truck to navigate through + how much waste/recycling is expected to be produced from a given building which ultimately determines the type of outdoor receptacle used.

Please let me know if you have any questions!

Thank you,

Daphne
