Post-Lunch Time Waste Audit (Step 4)

June 9 2020

Post Organics Diversion Waste Audit is performed to see if metrics are close to first waste audit waste diversion potential.

Summary

A second waste audit was done on January 14th to measure a few things: how student sorting was progressing; measure the current levels of waste diversion and contamination rates; compare current waste diversion rates to the first audit's waste diversion potential rate. 

Initial discussion with students reveals that there are challenges and successes to volunteering as bin monitors. Successes are a feeling of accomplishment and helping the planet and animals by minimizing waste to the landfill. Challenges include remembering volunteer days and times and managing peer relationships when it comes to other students not sorting correctly. 

The second waste audit reveals that students are potentially creating less total waste by weight because liquids are diverted from the landfill and compost bins (liquids were not taken into account during the first waste audit). 

The second waste audit also reveals that student efforts are exceeding the first audits waste diversion potential. Whereas the first audit predicted a 60% waste diversion rate, the second audit results are an actual waste diversion rate of 78%! Coupled with school-wide paper and cardboard recycling, it is estimated that FCE students and staff are diverting between ~90% of waste (by weight) from the landfill on a daily basis!!! Amazing!
