Wylie IS D’s S tory

In the fall of 2016, S tudent Nutrition Director introduced the EP A ’s Food Recovery Challenge as part of its S ustainable Materials Management Program. The challenge targets reducing “ food print” and reducing food waste in half by the year 2030.

SLIDE 27

With members of the energy management team, Wylie IS D set out to get baseline measurements out of each of its school cafeterias. Measurements were collected for liquid and solid waste. Y es… a week of dumpster diving!
