Last week we completed our first school wide waste audit! About 7-10 trash bins were audited and all data was recorded using 4 platforms; weight, volume, frequency, and observation.

The school wide waste audit included trash cans from hallways, classrooms, and the cafeteria. We began the audit by laying out tarps and bins to sort the trash into. Some surprising things we found in the trash were body sprays, untouched lunches, a whole Capri Sun, and a condom.


From this activity we were hoping to better understand how much recycling compost and trash our school produces. From this information we can then decide what size cans would be appropriate for our school. We don’t want to have one overflowing bin, but another one that is nearly empty. One of the ways this audit was different from the classroom audit was that it had a lot more lunch items.

We calculated that there was 71% compost, 20% recycling, and only 9% landfill.We hypothesized that people threw their lunch waste away in the hallways or outside, less than in the classrooms. This second audit gave us even more evidence that the three bin system is needed at Oakland Tech, because we have so much compost and recycling that is going into the landfill.
